Installation Instructions
Safety Requirements
1. The SMARTLINK® MRV system should be used for positioning of multiple valves/dampers to control the air/fuel ratio to industrial/
commercial burners. The product is intended to replace mechanically or pneumatically linked air/fuel ratio control equipment in
combustion applications that can benefit from increased positioning repeatability and tamper resistance. If the equipment is used in a
manner not specified, the protection provided by the equipment may be impaired.
2. This product performs fail-safe air and fuel valve positioning only and does NOT include any air proving, flow monitoring, flame
detection, or burner management functions. This product operates in response to burner management start-up commands (i.e. Purge,
Light-off, Modulate) and to the temperature controller's output (or Firing Rate command) after burner start-up.
3. The SMARTLINK® MRV system is only responsible for proper positioning of valves/dampers attached to its actuators. If burner air/fuel
ratio can be significantly affected by other control motors, fans, variable frequency drives, or large changes in process operating
conditions, it is the commissioning engineer's responsibility to apply external equipment to detect unsafe air/fuel ratio operating
conditions.
4. This product must be set-up and maintained by qualified combustion personnel. Before operating this product, read all installation,
commissioning, and operating instructions (pages 10-30.7-43 through 10-30.7-89). Review all product specifications on pages 1030.7-5 and 10-30.7-6 to ensure the product is suitable for the intended application. During the burner commissioning process, external
equipment (i.e. flow/pressure devices, O2 analyzer, etc.) or a view of the burner flame is required to ensure proper valve position setup.
5. This product must be electrically interfaced to the burner management system's permissive circuit or the automatic burner control's
safety circuit. This important wiring requirement ensures that any failure within the SMARTLINK® MRV system can shut down the
combustion system or disable a start-up sequence by turning off the main gas supply to the burner (i.e. de-energizing fuel shut-off
valves). Specifically, MAXON Relay Output Interface contacts (CE1/CE1R, CE2/CE2R, CO1/CO1R) must be connected in series with
the permissive circuit. If the minimum system is purchased and the Relay Output Interface is not provided, it is the commissioning
engineer's responsibility to connect the MAXON Control Interface relay drive outputs (RO2 and RO5) to appropriate interface relays
for safe shut down.
6. A current loop output signal (OUT+/OUT- of the Control Interface) is provided for optional monitoring of the start-up state, firing rate,
and valve position (during commissioning). This signal is not designed as a fail-safe output and should not be used by external
equipment to shut down the combustion system without the use of the SMARTLINK® MRV discrete permissive outputs (as discussed
in the previous safety requirement).
7. After mechanical replacement and re-calibration of a valve actuator, the previously commissioned valve positions must be re-verified.
8. The SMARTLINK® MRV Relay Output Interface (ROI), Purge Position Proven (PPP) and Light-off Position Proven (LPP) signals
should be connected to the burner management (or automatic burner control) if a purge and light-off command sequence is required.
These output signals are used to confirm the purge and light-off positions. If the optional Relay Output Interface is not purchased,
Control Interface relay drive signals RO3 and RO4 must be properly connected to customer-supplied interface relays.
9. If the power supply is not MAXON-supplied, a SELV (Safety Extra Low Voltage) rated supply with 24VDC output must be provided.
10. If the components of a SMARTLINK® MRV system are ordered separately (i.e. without a factory-wired Interface Panel assembly), the
commissioning engineer must incorporate a switch or circuit breaker that is in close proximity to the SMARTLINK® system. The switch
or breaker must be marked as the disconnection device for the equipment.
11. To avoid unsafe operating conditions or injury to fingers in the valve adapter assembly, turn off power to the system before actuator
replacement or valve body (or damper) servicing is performed. Read and follow all instructions for actuator removal and re-installation
as described on Page 10-30.7-68. After actuator replacement or valve body servicing, the commissioning engineer must verify burner
performance through the entire operating range and re-adjust valve positions (for the replaced actuator) as required. Refer to the
Commissioning Procedures on Pages 10-30.7-61 through -62. After any actuator replacement or valve body servicing, the
commissioning engineer must also confirm that the valve actuator number "selected" for re-adjustment (using the Control Interface or
User Display) is attached to a known valve body or damper. If a User Display is purchased, the fluid type associated with each valve
actuator should be defined as described in step a of the Commissioning Procedure on Page 10-30.7-63 and this will avoid any
confusion on which actuator controls which valve. Actuators purchased as part of a 2, 3 or 4 valve actuator system are numbered
electronically during manufacturing as #0, #1, #2 and #3. A spare actuator is always identified as #4 and is changed to a #0, 1, 2 or 3
during the replacement procedure. A green diagnostic LED in the actuator's wiring compartment and labeled "DIAG" indicates the
valve number by blinking 0 (always ON), 1, 2, 3 or 4 times per second. On the actuator label, the last digit of the model number also
indicates the valve actuator's number (with the exception of the spare actuator).

SMARTLINK® MRV Components
As shown below, the minimum SMARTLINK® MRV system requires two Valve Actuators and one (DIN rail-mounted) Control
Interface. A total of four Valve Actuators can by supported by one Control Interface. In addition, several optional DIN rail-mounted
components are available to simplify electrical interfacing and commissioning. These optional components include:
a) Relay Input Interface – Provides the electrical interface between the 6 Control Interface inputs and the customer’s burner
management or flame safety device. This device is available in 120VAC, 230VAC, and 24VDC models.
b) Relay Output Interface – Provides the electrical interface between the 5 Control Interface outputs and the customer’s burner
management or flame safety device.
c) Network Interface – Provides a plug-type terminal connector for all SMARTLINK® MRV field devices.
d) User Display – Provides a 4-line x 20-character LCD display for system commissioning and maintenance.
e) Universal Power Supply – Provides regulated 24VDC power to all SMARTLINK® MRV system components.
These optional components can be ordered individually and wired by the customer. However, two SMARTLINK® MRV Interface
Panel assemblies are available with factory-wired components as follows:
(1) 24” x 20” Interface Panel: Includes factory-wired Input & Output Relay Interfaces, Network Interface, Supply, Control
Interface, User Display, and Terminal Block Assembly
(2) 20” x 16” Interface Panel: Includes factory-wired Input & Output Relay Interfaces, Network Interface, Supply, Control
Interface, and Terminal Block Assembly
The larger, 24” x 20” Interface Panel includes a User Display. Both Interface Panels provide a 4-Amp breaker and power switch as
well as a labeled terminal block for field wiring.
The Interface Panels can be specified with a windowed, NEMA 4X enclosure in painted steel, 304-stainless or 316-stainless.
When provided with a NEMA 4X enclosure, the complete package is Class I, Division 2, and ATEX and IEC Ex approved
and no purging equipment is required.
Because SMARTLINK® Valve Actuators communicate digitally to the Control Interface, an EIA Level 4 Cable with 2 twisted pair
and shield is required for these connections. Required cable may be purchased from MAXON. See the Electrical Installation
section for wiring specifications.

Electrical Installation
The SMARTLINK® MRV System block diagram below indicates the sources and destinations of all electrical wiring. If the Control
Interface is ordered with an Interface Panel assembly, the following field wiring is required:
•
120/230 VAC supply and protective earth wiring between the customer’s fused, AC power source and Interface Panel
terminal block (L1, L2, and PE).
•
Low voltage 4-20 mA firing rate command and feedback signal wiring between the user’s process controller and Interface
Panel terminal block (INA+, INA-, OUT+, and OUT-). The shield wire for the firing rate command (INA+ and INA-) should be
grounded immediately as it enters the enclosure that houses the MRV Interface Panel. If the Interface Panel is purchased
with the enclosure option, terminate the shield wire on the corner ground post closest to where the cable enters. The shield
wire for the 4-20 mA firing rate feedback (OUT+, OUT-) should be terminated only at the process or temperature controller end.
•
Input Command Relay wiring between the customer’s burner management or flame safety device and the Interface Panel
terminal block (PPC, LPC, MVC, RRC, and CCOM). The ground reference (CCOM) must be wired for any of the input
command signals to function.
•
Output Relay wiring between the customer’s burner management or flame safety system and the Interface Panel terminal
block (ALM/ALMR, CE2/CE1R, PPP/PPPR, and LPP/LPPR).
•
Communications Network wiring between each SMARTLINK® Valve Actuator (+24, GND, DA, DB, SHD) and the 4-terminal
connectors (F24+, F24-, DA, DB) of the Network Interface. The shield wire of each network cable should be connected to the
actuator “SHD” terminal (keeping the shield length to 1 inch or less). The shield wire should also be tied to ground as it enters
the enclosure of the MRV Interface Panel (keeping the maximum length to 6 inches or less). If the Interface Panel is
purchased with the enclosure option, terminate the shield wire on the corner ground post closest to where the cable enters
the enclosure.

Electrical Installation
The MRV Interface Panel includes a Universal Power Supply, Relay Input Interface, Relay Output Interface and Network
Interface module. (The 24” x 20” Interface Panel also includes a User Display.) These DIN rail-mounted devices are factory-wired
to the SMARTLINK® MRV Control Interface and a labeled terminal block assembly for field wiring as shown in the wiring diagram
below. A “typical” electrical schematic of a SMARTLINK® MRV system is also provided as a representative example of how the
system is interfaced to a temperature controller and flame safety device.
To ensure the burner can be shut down in the event of a SMARTLINK® MRV failure, the commissioning engineer must verify
specific output connections to the burner management equipment or automatic burner controls. Reference the following electrical
wiring information for fail-safe system operation: a) Example Wiring Diagram: Lines 103 and 104 (page 10-30.7-50), b) Table 1,
Interface Panel Terminal Descriptions: CE1/CE1R, CE2/CE2R and CO1/CO1R, c) Table 4, Control Interface Terminal
Descriptions: RO2 and RO5 and d) SMARTLINK® MRV Safety Requirements #5 and #6 (page 10-30.7-43).
Electrical wiring should be performed in accordance with all local and NEC 1 codes. See Reference Table 1 and Table 2 (pages
10-30.7-69 and 10-30.7-70) for terminal descriptions of the MRV Interface Panel and Valve Actuator. Reference Table 3 (page 1030.7-71) summarizes the maximum length, type, and size of all field wiring required for the MRV Interface Panel.
The AC power (mains) wiring must be permanently installed and not supplied as a detachable line cord.
If the Control Interface is purchased without a factory-wired Interface Panel, see Reference Tables 4 through 9 (10-30.7-72
through -77) for terminal descriptions of the individual SMARTLINK® MRV electronic components: Control Interface, Relay Input
Interface, Relay Output Interface, Network Interface and User Display.

with the burner management permissive/interlock circuit to ensure the burner can be shut down in the event of a SMARTLINK® MRV
failure. If the SMARTLINK® MRV system is purchased without a MAXON Relay Output Interface (ROI), the commissioning engineer is
responsible for verifying that appropriate interface relays are wired to the burner management system and Control Interface relay drive
outputs, RO2 (and RO5 for systems with software version release 1C or later).
NOTE 10: This wiring schematic represents electrical connections in a "typical" product application. Please refer to the schematics of the specific
application for troubleshooting.
Maintain the integrity of the MAXON enclosure by using NEMA 4X or IP66 rated dust- and water-tight
electrical connectors. Use cable-sealing grips and strain-relief loops for any cord or cable. Use internal
sealing materials on all conduit connections. Moisture can have a harmful effect on device internals if
permitted to enter through wiring connectors. Ensure that the device connection is not at a low point of the
conduit to avoid condensation run-off into the housing; install a drip loop if necessary. Make sure that the
access cover plate is in place and securely fastened. All cover screws should be tightened using an
alternate cross-corner tightening pattern. Cover screws should be checked periodically to ensure
adequate sealing protection.

Each of the user commands can be initiated by following the general command entry procedure outlined below.
General Command Entry Instructions:
1. A user command can be performed only when the following conditions are all satisfied:
a.) Mode switch is not in the RUN position,
b.) One of the green Command Set lights (a, b, c) is blinking,
c.) ADJUST switch is not in the MINIMUM position,
d.) Unit is “unlocked”, and
e.) For some commands, the unit must be in a specific mode, position index, etc. (See command entry requirements listed on
page 10-30.7-56 or in Reference Tables 12 through 14 on pages 10-30.7-80 through -84.)
Note: Condition d. above is not required for Command A-7, Unlock Configuration and Command A-1, Display Alarm Codes.
2. If the a, b, or c Command Set light is not blinking, momentarily push the MODE switch in the CMD abc position (up) or, change
the position of the rotary CMD SEL switch. This will start the Command Set light blinking and permit a command to be
entered.
3. Select the desired Command Set by momentarily pushing the MODE switch upward to the CMD abc position. Subsequent
CMD abc switch entries will change the command set selection as indicated by the green Command Set (a, b, c) lights.
4. Select the desired command number by changing the position of the rotary CMD SEL switch. When one of the command set
lights is blinking, the command number selected is indicated by the corresponding numbered (0-9) light being lit.
5. After the command set and number are selected, press the ENTER button. If all of the numbered lights flash momentarily
after the ENTER button is pushed, a command entry error has occurred and the command was not executed. If an entry error
occurs, check to see if the unit is locked (i.e. alarm light blinking) or the ADJUST switch is in the MINIMUM position. If neither
condition exists, check the specific entry requirements of the command.

Wiring Checkout
Before applying power to the SMARTLINK® MRV Interface Panel, Control Interface, or Valve Actuators, perform the following
wiring checkout:
1) Verify that 120 VAC (or 230 VAC) power and burner management control signals are connected to the proper field wiring
terminals of the SMARTLINK® MRV Interface Panel.
2) If a factory-wired MAXON SMARTLINK® MRV Interface Panel was not purchased, verify that no 120 VAC (or 230 VAC) wiring
is connected directly to any Control Interface or Valve Actuator terminal. The MRV Control Interface (and Valve Actuators)
must be powered by a 24 volt DC source.
3) Verify the proper wire type and maximum wire length requirements are satisfied for all connections.
4) Verify network/power connection color codes are correct for the Valve Actuators.
5) Measure the resistance between earth ground at the enclosure of the Control Interface and each of the four signals wired to the
Valve Actuator: F24+ (Field 24VDC), F24- (Field 24VDC Common), DA (Data-A), and DB (Data-B). The resistance should
indicate an open circuit (i.e., a resistance value greater than 10 Ohms). If an open circuit is not measured, damage or incorrect
wiring of the control network cable exists and must be located.
6) Verify proper termination of shields for the 4-20 mA cables and the power/network cable between the SMARTLINK® MRV
Interface Panel, Control Interface and Valve Actuators.
7) If a MAXON SMARTLINK® MRV Interface Panel is not provided, verify that all customer-provided output relays connected to
RO1 through RO5 of the Control Interface have a 24 VDC coil rating and require less than 100 mA to turn on.
Refer to SMARTLINK® MRV Reference Tables 1 through 5 (pages 10-30.7-69 to -73) for all terminal definitions and wiring/
shielding requirements.

Operational Checkout
Apply power to the SMARTLINK® MRV System. If a SMARTLINK® MRV Interface Panel was purchased, switch the breaker
located on the lower rail of the Interface Panel to the ON (or up) position. The breaker switch will power all system components
including the SMARTLINK® Valve Actuators. Perform the following operational checkout prior to attempting burner light-off and
commissioning the system for burner operation:
1) Disable the burner system by turning the combustion blower off and manually turning off the pilot and main fuel supply.
2) Place the Mode switch of the Control Interface in its middle position. With all Valve Actuators wired, verify the Control Interface
Alarm light is off and the Run light is blinking indicating the system is in the Startup Mode. If the Control Interface alarm light is
on, see page 10-30.7-66 on troubleshooting and alarms, to determine the cause of the alarm and corrective actions.
3) Verify operation of each SMARTLINK® MRV relay output by using the procedures summarized in Table 10 (page 10-30.7-78).
If a MAXON MRV Interface Panel is provided, the Relay Output Interface (ROI) is factory-wired to the Control Interface and a
field wiring terminal block for easy access to the output contacts. The relay output terminals of the Control Interface are also
referenced in Table 10 to assist in operational checkout of systems with customer-supplied relays or a PLC-based burner
management system that controls burner startup (without the MAXON Relay Output Interface).
4) Turn on the combustion blower. Re-enable the burner management system but keep the pilot and main fuel supply turned off.
Verify that all combustion system safety interlocks are satisfied.
5) Power cycle SMARTLINK® MRV and verify the relay input commands from the burner management system properly drive
SMARTLINK® MRV to its purge and light-off states. If a MAXON SMARTLINK® MRV Interface Panel is provided, the Relay
Input Interface (RII) is factory-wired to the Control Interface and a field wiring terminal block. The lights of the Relay Input
Interface indicate when each input command relay is energized and the 4-20 mA output (OUT-/OUT+ terminals) can be
measured by a current meter to verify SMARTLINK® MRV has responded to the input command. When the burner
management system (or flame safety) issues a Purge Position Command, the PPC terminal of the Interface Panel is energized
and the Relay Input Interface (terminal #6) outputs a voltage greater than 22 VDC to the Control Interface input terminal RI1
(Relay Input #1). When a Light-Off Position Command is issued, the LPC terminal of the Interface Panel is energized and the
Relay Input Interface (terminal #5) outputs a voltage greater than 5 VDC to the Control Interface input terminal RI2 (Relay Input
#2). The following 4-20 mA output currents can be measured for each of the following SMARTLINK® MRV states: 1 mA=
Standby Positions; 2 mA = Purge Positions; 3 mA = Light-Off Positions.

10-Point System Commissioning
The SMARTLINK® MRV Control Interface is shipped with configuration settings that support a 10-point commissioning procedure
as described on the following page. Specifically, the Auto Ramp ON configuration is selected as the default setting so that fuel
valve adjustment is needed for only 10 position indexes (0, 1, 2…9). The 9 intermediate position indexes (0.5, 1.5, 2.5, etc.) are
automatically set to positions mid-way between the 10 integer position indexes, 0 through 9. In addition, the Default Startup
Configuration sets the standby, purge, and light-off positions to the same values as those established for Index 0 (minimum), Index
9 (maximum), and Index 0 (minimum), respectively. See Reference Table 11 for a detailed description of these configuration
settings.
When SMARTLINK® MRV is in the Position Setup Mode for commissioning, the ADJUST switch can be pushed to the MINIMUM
position (down). This action will immediately move the valves synchronously to position index #0, the minimum position. This
feature provides a method (during commissioning when the user’s temperature controller is not in automatic mode) to quickly ramp
the burner back to low fire if a process or combustion condition warrants an immediate burner firing rate change.
An optional User Display with a 4-line by 20 character LCD can also be used for SMARTLINK® MRV commissioning instead of
the Control Interface switches and lights. The commissioning procedure using the User Display is described on page 10-30.7-63.
See Reference Table 15 on page 10-30.7-85 for a description of User Display key operation and commands, as well as a
numbered menu structure.
19-Point System Commissioning
There are combustion applications that require burner adjustment at more than 10 points throughout the firing range to meet
emissions or fuel efficiency requirements. For these applications, the Auto Ramp configuration should be OFF, setting #0. With
Auto Ramp OFF, adjustment of each fuel valve at all 19 position indexes (0, 0.5, 1.0, 1.5…8.5, and 9) is now required and no
automatic “smoothing” is performed on points adjacent to the position index being adjusted. The procedure for adjusting all 19
points is identical to the 10-point procedure described above with the following exceptions:
1.) In step g of the 10-Point Commissioning (using the Control Interface) procedure on page 10-30.7-62, execute Command B-6 to
ensure the auto ramp function is OFF, setting #0. In step g of the 10-Point Commissioning (using the User Display), go to Main
Menu 9 (Set Configuration) and use the ARROW up key until the auto ramp configuration can be verified.
2.) In step h, the firing rate should be adjusted at 0.5-position index steps instead of every whole integer position index.
In some applications, it may also be desirable to adjust positions at all 19 points of the air valve(s) in order to provide a linear flow
characteristic. The same 19-point adjustment process used for the fuel valves would be performed for the air valve(s) instead of
the 2-point linear position setup using Commands A-5 and A-6 (described in steps c through e).
Custom Start-up Positions
The Custom Startup Configuration is intended for burners or applications that require standby, light-off, or purge positions that are
independent of the burner’s normal operating valve position curves.
To enable this function using the Control Interface, execute Command B-4, Select Startup Configuration. Use the INC/DEC
switch to select setting #1 (Custom Startup) and press the ENTER switch to save the configuration setting if it has been changed.
Command B-1 (Set Purge Positions), Command B-2 (Set Standby Positions), and Command B-5 (Set Light-Off Positions) can now
be executed to set custom valve positions during startup. See Reference Table 13 for a more detailed explanation of how to use
these commands.
These custom startup adjustment commands can also be executed from the User Display using Main Menu 9 to select the
Startup Configuration item (using the ARROW keys) and Sub-Menu 9.1 to change (ARROW keys) and save (ENTER key) the
setting. See Reference Table 15 (page 10-30.7-85) for the User Display command menu structure.

SMARTLINK® MRV 10-Point Commissioning Procedure with Control Interface
Disable burner light-off by turning off the burner management system or disabling a combustion permissive so that interlocks
cannot be proven. Turn on the combustion blower.
Execute Command A-0, Enter Manual Mode. With the ADJUST switch in the up (INDEX) position, push the INC/DEC switch
momentarily to advance the firing rate to position index #9.
Execute Command A-3 and select the SMARTLINK® Air Valve Actuator’s number by using the INC/DEC switch to light the
desired valve number. (The number of the Air Valve Actuator is on the unit’s label.) Execute Command A-5, Set Max Position & Ramp, and adjust the air valve maximum position to satisfy the pressure/flow requirements of the burner. When this
command is executed, both the yellow and green run lights will be flashing indicating the system is in Position Setup Mode.
With the ADJUST switch in the middle (ADJ) position, push the INC/DEC switch up or down to change the valve position.
Each push of the INC/DEC switch moves the valve 0.1 degrees. If the switch is held in the up or down position for more than
3 seconds, the valve will move in 0.5 degree steps up to a total travel of 8 degrees from the stored valve position. (All the
numbered lights will momentarily flash when this 8 degree limit or the maximum valve travel is reached.) After moving the
valve to the desired position, press the ENTER button to save the position setting. The command ‘a’ light will momentarily
turn off and then back on (solid) after the position is saved. (Any numbered light that was blinking will also momentarily turn
off and then resume blinking after the position is saved.) Record the valve position feedback in milliamps (mA) or percent
that is present on the OUT+/- terminals of the Control Interface.
Execute Command A-0, Enter Manual Mode, again and move to position index #0. Execute Command A-6, Set Min Position
& Ramp, and adjust the minimum air valve position in the same manner as the maximum position was adjusted in step d.
Repeat steps b through e for all other air valves installed. SMARTLINK® MRV is shipped with factory default minimum and
maximum valve positions of 6.0 and 60.0 degrees, respectively.
Momentarily set the mode switch in the RUN position, re-enable the burner management system and light the burner. Execute Command B-6 to ensure the auto ramp function is set to #1, ON. Select the fuel valve for adjustment using Command
A-3 and then execute Command A-6, Set Min Position and Ramp. This command permits adjustment of the minimum position and then creates a linear ramp to the current maximum position. The system is placed in Position Setup Mode, indicated
by the flashing of both the yellow (MANUAL) and green (RUN) lights. With the ADJUST switch in the middle position, trim the
fuel valve's position at index #0 (minimum) based on burner pressure or flow measurement equipment as performed in step
d above. Repeat this step to adjust the minimum and linear position ramp for all other fuel valves in the system.
After adjusting index #0 (and forcing a linear position ramp) for the fuel valve, place the adjust switch in the INDEX (up) position and execute Command A-2 (Enter Position Setup Mode). Move the MRV firing rate to the next whole integer position
index (index #1) by momentarily pressing the INC/DEC switch until the desired index number is turned ON. Move the
ADJUST switch back to the middle (ADJ) position. Use the INC/DEC switch to adjust valve position based on burner pressure or flow measurement and press ENTER to save the profile to memory as described in step d above. Repeat this adjustment procedure for each whole integer index up to and including index #9 (maximum). If necessary, make gas pressure
regulator adjustments at index #9 and then work back down through the lower indexes making adjustments as required.
After the last adjustment is made in Position Setup Mode, use the INC/DEC switch to move to position index #9 (or the highest position index adjusted for all valves) with the ADJUST switch in the INDEX (up) position. Select the air valve using Command A-3 and then execute Command A-4, Commission Valve. Repeat this step for each installed SMARTLINK® MRV valve
actuator. The commission command stores the selected valves current position index as its maximum allowable position
index while in RUN mode (i.e. under 4-20 mA firing rate control). If one valve has a "maximum run index" less than the other
commissioned valves, the system will not modulate above the lowest run index. The system will also not modulate in RUN
mode if any valve is not commissioned.
Record in the SMARTLINK® MRV commissioning table (Table 16, page 10-30.7-87 and -88) the position of each valve and
pressure (or flow) at each index. Execute Command C-6 to save the profile as a backup. Move the MODE switch to the
RUN position and set the user’s temperature controller to AUTO.

i) After the last adjustment is made in Position Setup Mode, go to Sub-Menu 5.1 (Set Index) and use the ARROW keys to move the system to
index #9 (or the highest possible with the burner firing). Go to Sub-Menu 5.7 (Commission) and press the ENTER key to execute the Commission Valve Command (A-4) for the selected valve. Use the ARROW keys to select each valve and then press ENTER to commission the
f)
j)
newly-selected valve. Repeat this process for each installed SMARTLINK® MRV Valve. The commission command stores the selected
valve's current position index as its maximum allowable position index while in RUN mode (i.e. under 4-20 mA firing rate control). If one
valve has a maximum run index less than the other commissioned valves, the system will not modulate above the lowest run index. The system will also not modulate in RUN mode if any valve is not commissioned.
To make a back-up profile in the Control Interface, go to Sub-Menu 5.9 (Save Back-up) and press ENTER to execute Command C-6, Save
Profile as Back-up. To back-up the profile and all system configuration settings in the User Display, go to Sub-Menu 10.4 (Save System
Data) and press ENTER. Backing up system data to the User Display takes approximately 30 seconds. Go to Sub-Menu 5.8 (Run Mode)
and press ENTER. Place the user's temperature controller in AUTO. SMARTLINK® MRV will modulate the burner's firing rate based on the
4-20 mA input command.

Unit Locking and Passcode Entry
The SMARTLINK® MRV Control Interface is shipped with the lock function disabled and a factory default 4-digit passcode or
“combination” of 0,0,0,0. To lock the unit for the first time and change the default passcode, the lock function must first be enabled
(Command C-5) and the default passcode entered (Command A-7) as described in the first two procedures below. After the lock
function is enabled and the unit is “unlocked”, a new passcode can be entered using Command C-4 as described in the procedure
below. If you forget the passcode, call MAXON for the “master” passcode.
Procedure for Enabling the “Lock” Configuration Setting (Command C-5):
a) If the alarm light is blinking, the lock function is already enabled and the unit is in a “locked” state. Before changing the passcode, the unit must be unlocked by entering the current passcode (Command A-7) using the procedure below.
b) If the alarm light is not blinking, select and enter Command C-5, Lock Enable/Disable.
c) After the command is entered, one of the numbered (0-9) lights will be on, indicating the current configuration setting. If the
#1 light is on, the lock function is already enabled and the procedure below can be performed to change the passcode. If the
#0 light is on, the lock function is disabled.
d) To select the #1 setting (Lock Enable), momentarily push the INC/DEC switch in the up position. The #1 light will now be on,
indicating the new setting is selected.
e) Push the ENTER button. The #1 light will turn off indicating the command is complete and the configuration setting is saved.
The unit is now locked and the alarm light will be blinking. To change the current passcode, perform the next two procedures
(Command A-7 & C-4).
Procedure for Entering the Current “Lock” Passcode (Command A-7):
a) Select and enter Command A-7, Unlock Valve Configuration.
b) After the command is entered, the INC/DEC switch is used to select the first passcode digit. The digit selected is indicated
by a numbered light (0-9).
c) Once the first digit of the passcode is selected, push the ENTER button once. The numbered light should momentarily turn
off indicating the entry was accepted.
d) Repeat steps b and c for the 2nd, 3rd, and 4th passcode digits. If the passcode was entered incorrectly, all the numbered lights
will momentarily flash after entry of the 4th and final passcode digit. If the passcode was correct, the alarm light will stop flashing and will be turned off completely if no other alarms exist.
e) To change the current passcode, perform the procedure (Command C-4) below.
Procedure for Entering a New “Lock” Passcode (Command C-4):
a) To enter a new lock passcode, the lock function must be enabled (Command C-5) and the current passcode must be entered
(i.e. the unit must be “unlocked” using Command A-7). See the two previous procedures if these command entry requirements have not been satisfied.
b) Select and enter Command C-4, Enter New Lock Combination.
c) After the command is entered, the INC/DEC switch is used to select the first new passcode digit. The digit selected is indicated by a numbered light (0-9).
d) Once the first new digit of the passcode is selected, push the ENTER button once. The numbered light should momentarily
turn off indicating the entry was accepted. Write down the new digit for later use.
e) Repeat steps c and d for the 2nd, 3rd, and 4th passcode digits, remembering to write down each passcode digit as it is entered.
f) Verify the new passcode by re-locking the unit (MODE switch to the RUN position and then back to the middle, Command
Entry position), and entering the new passcode using Command A-7 as described in the procedure above.

Manual Operation
Command A-0, Enter Manual Positioning Mode, is used to override the 4-20 mA position command input and the startup (burner
management) command inputs (i.e. Purge Position, Lightoff Position, Standby Position). This command is used during the
operational checkout of the system prior to commissioning and after commissioning to verify burner performance at each position
index.
Procedure for Entering Manual Positioning Mode (Command A-0):
a) Select and enter Command A-0, Enter Manual Positioning Mode. If the numbered lights flash momentarily after entering
Command A-0:
• The ADJUST switch may be in the MINIMUM position, or
• The unit may be “locked” to prevent tampering.
b) After entering the command, the yellow manual (MAN) light will be on. The INC/DEC switch can be used to move the valve
open or closed. If the ADJUST switch is in the INDEX position, the INC/DEC switch is used to move between the 19 position
“indexes”. If the ADJUST switch is in the ADJ position, pushing the INC/DEC switch up or down changes the valve position
in 1.0-degree steps. If the INC/DEC switch is held in the up or down position, the position is continuously adjusted until the
maximum or minimum position is reached. When the max or min position setpoint is reached, all the numbered lights will
momentarily flash.
c) To return control back to the 4-20 mA firing rate command input or burner management startup control, move the MODE
switch to the RUN position (down).
Power Loss with Large Valves (>12”)
Do not remove power from an air valve actuator when both 1) the valve is open more than 30 degrees, and 2) the blower is running.
Prior to power loss, ensure that the valve position is less than 30 degrees open, and/or that the blower has stopped. Failure to
observe these precautions can result in permanent damage to the valve actuator.

Actuator replacement should be accomplished by MAXON-trained personnel only.
Actuator Removal
1.
2.
3.
4.
5.
6.
Power down the SMARTLINK® MRV system. Turn off the fuel supply and burner management system.
Remove the actuator access cover using a 4 mm Allen wrench and verify the green power light is OFF.
Record the wire color code sequence and then disconnect the four wires and shield from the terminal block. Disconnect any conduit fittings.
Loosen the clamp collar screws with a 3/16” Allen wrench.
Remove the four M6x1x18 mm screws connecting the actuator to the adapter with a 5 mm Allen wrench.
Remove the actuator by holding the actuator housing and pulling the actuator away from the valve.
Actuator Reinstallation
1. Inspect the actuator coupling. Identify the type of key required based on the photos below.
2. Verify the clamp collar is loose and position the screw head on the left when looking at the clamp collar at the top.
3. Place the actuator shaft with key into the clamp collar. Slide the keyed shaft into the coupling key slot, then rotate the actuator housing so
the alignment pin mates with the pin hole in the valve adapter. The parts are a clearance fit but should slip together with little force. Apply
pressure until the actuator is flat against the adapter. Do not apply an excessive force. If the sub-assemblies do not mate together, recheck
that the clamp is loose and the key is pressed to the bottom of the key slot.
4. Verify that the valve will close completely. With the valve closed, the coupling hard-stop pin should be centered and touching the hard-stop
set screw for butterfly valves. For ball valves, the coupling should hit on the two vertical hardstop pins in the bracket.
5. With valve in the fully closed position, assemble the actuator to the valve adapter with four M6x1x18 mm fasteners using Loctite 242. Use a
torque wrench with a 5 mm Allen bit to apply 18 in-lbs of torque in an alternating diagonal tightening sequence.
6. With the valve in the fully closed position, verify that the clamp collar is seated flush against the coupling shoulder. Tighten the stainless
steel clamp collar with a torque wrench and 3/16” Allen bit to 170 in-lbs .
7. Make the necessary water-tight electrical conduit connection. Re-connect the four wires to the terminal strip per the original color code
sequence. Re-connect the shield wire to the terminal strip, keeping it less than 1” in length.
8. Apply power to the SMARTLINK® MRV System. Verify the green power light is ON.
9. Reinstall the access cover and torque the four fasteners to 18 in-lbs using a 4 mm Allen wrench.
10. Make sure the system is in Shutdown Mode (i.e. The Control Interface RUN and MANUAL lights are off and ALARM light is on.) If not,
disconnect power for 10 seconds to the valve actuator being replaced and re-power the actuator after the system enters Shutdown Mode.
11. With the Control Interface, select the valve number that is being replaced (Command A-3). Next, execute Command A-4, Commission Valve.
This command electronically "replaces" the spare unit (valve #4) as the valve requiring replacement (valve #0, 1, 2 or 3). If a User Display is
used, select the valve to be replaced and execute the "Replace" command (Sub-Menu #11.5) under the Valve Maintenance Main Menu #11.
12. Execute Command C-1, Enable Calibration, from the Control Interface or the User Display. If all the numbered lights flash on the Control
Interface after command entry, the command was not successfully executed. Refer to Table 14 (page 10-30.7-84) for detailed command
information. In the User Display, this command is available under the Valve Maintenance Menu in the Test Mode Sub-Menu (#11.1).
Successful completion of this command will result in the test mode being displayed as "ON".
13. Execute Command C-2, Calibrate Valve. This command takes approximately 3 minutes. If the command is executed from the Control
Interface, the even numbered lights will flash on and off. If the command is executed from the User Display (Sub-Menu #11.4), the valve
positions displayed will slowly change as the valve moves through its full travel. Refer to Table 14 for detailed command information. If the
command is executed from the Control Interface and all the lights flash on and then off, the calibration procedure did not execute properly.
14. Power the complete system down and then up. If a valve calibration alarm still exists, the calibration command did not complete successfully.
Verify that the actuator was mounted properly as described above and perform the previous steps again.
15. Turn on the fuel supply and burner management system and re-verify burner performance throughout its full firing range. The valve attached to
the new actuator will be within approximately 1 degree of its previously commissioned positions due to mechanical tolerances. Verify burner
operation with the new actuator through its entire firing range and re-commission.

During Startup Mode: Output represents startup system status; 1 mA = all valves in standby positions; 2 mA = all valves
in purge positions; 3 mA = all valves in light-off positions
During Position Setup Mode: Output represents the actual position of the selected valve so that system commissioning is
possible using only a 4-20 mA meter; 4 mA = 0.0 degrees; 20 mA = 80.0 degrees; Actual valve position = [current (mA) 4.0 mA] / 16.0 mA * 80.0 degrees
Relay Input Connector
The following relay inputs are solid-state and require 5-24VDC and 2 mA (max) to turn "ON".
Note #1: RI1 through RI6 must all be referenced to RCOM
Note #2: If the Control Interface is used with the MAXON Relay Input Interface (RII) module, the RI1-RI6 inputs below can
be connected to Relay Input Interface, terminals #6-#1.
Relay In 1 (RI1)
Input: The ON state of Relay Input #1 drives all SMARTLINK® MRV valves to their maximum or user-defined, custom
purge positions if either RI2 and RI3 are not ON.
Relay In 2 (RI2)
Input: The ON state of Relay Input #2 drives all SMARTLINK® MRV valves to their minimum or user-defined, custom lightoff positions if RI 3 is not ON.
Relay In 3 (RI3)
Input: The ON state of Relay Input #3 enables all SMARTLINK® MRV valves to synchronously modulate based on the 420 mA firing rate command signal. When RI3 is ON, commands from either or both RI1 and RI2 inputs are overridden.
Relay In 4 (RI4)
Input: A momentary ON state of Relay Input #4 resets the MRV when a fault has occurred and the system is in Shutdown
Mode. (See page 10-30.7-66 for fault condition descriptions.)
Relay In 5 (RI5)
Input: Relay Input #5 is reserved for future use.
Relay In 6 (RI6)
Input: Relay Input #6 is reserved for future use.
Relay Output Connector
The following relay drive outputs are solid-state, 30VDC, 100 mA (max) open collectors.
Note #1: RO1 through RO5 must all be referenced to RCOM
Note #2: If the Control Interface is used with the MAXON Relay Output Interface (ROI) module, the following RO1-RO5
outputs can be directly connected to Relay Output Interface, terminals #1-#5.
Relay Out 1 (RO1)
Output: Relay drive Output #1 is turned ON if one or more MRV alarm or fault conditions exist. (See page 10-30.7-66 for
alarm/fault descriptions).
Relay Out 2 (RO2)
Output: Relay drive Output #2 is turned ON when no MRV system fault exists; RO2 is turned off when one or more
SMARTLINK® MRV "fault" conditions exist. (See page 10-30.7-66 for descriptions of fault conditions.)
WARNING: If the SMARTLINK® MRV system is purchased without a MAXON Relay Output Interface (ROI) module, it is
the commissioning engineer's responsibility to verify the wiring of RO2 (RO5 for systems with software version release
1C or later). Proper wiring of RO2 and its associated interface relay to the burner management equipment is an essential
safety requirement for burner shut down in the event of a SMARTLINK® MRV failure.
Relay Out 3 (RO3)
Output: Relay drive Output #3 is turned ON when all MRV valve positions are greater than or equal to their maximum
positions or user-defined, custom purge positions.
Relay Out 4 (RO4)
Output: Relay drive Output #4 is turned ON when all MRV valve positions are less than or equal to their minimum positions or user-defined, custom light-off positions.
Relay Out 5 (RO5)
Output: For systems with software version 1C or later, Relay drive Output #5 is turned ON when no MRV system fault
exists; RO5 is turned OFF when one or more SMARTLINK® MRV "fault" conditions exist. (See page 10-30.7-66 for
descriptions of fault conditions.)
WARNING: If the SMARTLINK® MRV system is purchased without a MAXON Relay Output Interface (ROI) module, it is
the commissioning engineer's responsibility to verify the wiring of RO5 (and RO2). Proper wiring of RO5 and its associated interface relay to the burner management equipment is an essential safety requirement for burner shut down in the
event of a SMARTLINK® MRV failure.

Checkout Procedure to verify proper relay operation
Relay Out 1 (RO1)
Cycle system power off and then on with the Control Interface Mode switch in the middle position. Temporarily disconnect the communication and power to one of the Valve Actuators by
unplugging its connector on the Network Interface. Within a few seconds, the Alarm relay, connected to the RO1 terminal of the Control Interface, is energized and the RO1 terminal is driven
to less than 1.6 VDC in the ON state. Verify the Alarm light of the Relay Output Interface is on
and the contacts are closed between AL and ALR.
Relay Out 2 (RO2)
Cycle system power off and then on with the Control Interface Mode switch in the middle position. After power up, the Control Enable relays, connected to the RO2 terminal of the Control
Interface, are energized. The RO2 terminal is driven to less than 1.6 VDC in the ON state. Verify
the Control Enable light of the Relay Output Interface is on and the contacts are closed between
CE1 and CE2R. (A jumper should exist between Interface Panel terminals CE1R and CE2. The
CE1 and CE2R output provides a redundant series contact to be used as a fail-safe combustion
system running interlock or permissive.) Temporarily disconnect the communication and power
to one of the Valve Actuators by unplugging the connector on the Network Interface. Within a
few seconds, the Control Enable relays are de-energized and the output contacts are opened.
RO2 is in the OFF state at 24VDC. Verify the Control Enable light of the Relay Output Interface is
now off and the contacts are open between CE1 and CE2R.
Relay Out 3 (RO3)
Execute Command A-0, Enter Manual Mode, using the Control Interface or User Display. Move
to position index #9, maximum. When the system has reached index #9, the Purge Proven relay,
connected to the RO3 terminal of the Control Interface, is energized and the RO3 terminal is
driven to less than 1.6 VDC in the ON state. Verify the Purge Proven light of the Relay Output
Interface is on and the contacts are closed between PPP and PPPR.
Light-Off Position Proven (LPP)
Relay Out 4 (RO4)
Light-Off Position Proven Return (LPLR)
Execute Command A-0, Enter Manual Mode, using the Control Interface or User Display. Move
to position index #0, minimum. When the system has reached index #0, the Light-Off Position
relay, connected to the RO4 terminal of the Control Interface, is energized and the RO4 terminal
is driven to less than 1.6 VDC in the ON state. Verify the Light-Off Position relay of the Relay
Output Interface is on and the contacts are closed between LPP and LPPR.
Custom Output #1 (CO1)
Custom Output #1 Return (CO1R)
Cycle system power off and then on with the Control Interface Mode switch in the middle position. After power up, the CO1 relay, connected to the RO5 terminal of the Control Interface, is
energized. The RO5 terminal is driven to less than 1.6 VDC in the ON state. Verify the CO1 light
of the Relay Output Interface is on and the contacts are closed between CO1 and CO1R. (The
CO1/CO1R relay contact serves as a fail-safe, redundant combustion permissive/interlock output.) Temporarily disconnect the communication and power to one of the Valve Actuators by
unplugging the connector on the Network Interface. Within ten seconds, the CO1 relay is deenergized and the output contacts are opened. RO5 is in the OFF state at 24VDC. Verify the
CO1 light of the Relay Output Interface is now off and the contacts are open between CO1 and
CO1R.

operation. The 3 startup commands include the Purge Position Command (PPC), Lightoff Position Command
(LPC), and Standby Position Command (SPC). The SPC command is active when both the PPC and LPC command inputs are not energized.
Default Startup (#0): PPC = maximum position for all valves, index #9; LPC = minimum position for all valves,
index #0; SPC = minimum position, index #0. For this configuration setting, adjustment of the minimum position
(Index #0) and maximum position (Index #9) will automatically change the purge (Index #10), lightoff (Index
#10.5), and standby (Index #9.5) positions.
Custom Startup (#1): For each valve, the user can define a position for each of the 3 startup commands (PPC,
LPC, SPC). This configuration setting enables Command B-1 (Set Purge Position), Command B-2 (Set Standby
Position), and Command B-5 (Set Light-Off Position).
Set Auto Ramp Adjust Auto Ramp ON
(B-6)
(#1)
The automatic ramp function is used during the Valve Position Setup Mode to create a linear position ramp
between the position being adjusted and the two adjacent position indexes. This provides a position "smoothing"
of the valve profile and simplifies valve characterization. Setting #0 is Auto Ramp OFF and setting #1 is ON.

Table 12: SMARTLINK® MRV User Commands - Command Set ‘A’
Table 12: SMARTLINK® MRV User Commands - Command Set ‘A’
SMARTLINK®
Commands Number: Name
Description of command purpose and usage
Command Set ‘A’
Command A-0 is used to enter a Manual Positioning Mode that overrides the 4-20 mA, firing rate command input. If the numbered
lights flash momentarily after entering Command A-0, the command was not executed for one or more of the following reasons:
- The ADJUST switch may be in the MINIMUM position,
- The system is in Shutdown Mode, or
- The system may be "locked" to prevent tampering.
A-0: Enter Manual Positioning
Mode
After entering Command A-0, the yellow manual light on the Control Interface will be ON. Once this command has been entered,
the INC/DEC switch can be used to change the firing rate. If the ADJUST switch is in the INDEX position, the INC/DEC switch is
used to move between the 19 electronic position "indexes". (See Reference Table 16, SMARTLINK™ MRV Commissioning
Sheet for the factory default valve positions for each index.)
If the ADJUST switch is in the ADJ position, pushing the INC/DEC switch up or down changes the firing rate in 1.0% steps. If the
INC/DEC switch is held in the up or down position, the firing rate will change until 0 or 100% is reached.
Note: This command should not be executed when the system is part of an operating process that requires continuous, closedloop temperature control.
A-1: Display Alarm Codes
After entering Command A-1, the INC/DEC switch is used to scroll through all current alarm conditions. If the red alarm ("ALM")
light on the Control Interface is off, no alarm conditions exist. (See page 10-30.7-66 for troubleshooting and alarm descriptions)
Command A-2 is used to enter the Position Setup Mode for modifying the 22-position profile. If the numbered lights flash momentarily after entering A-2, the command was not executed for one or more of the following reasons:
- The ADJUST switch may be in the MINIMUM position,
- The system is in Shutdown Mode, or
- The system may be "locked" to prevent tampering
A-2: Enter Valve Position Setup
Mode
After entering Command A-2, both the yellow manual light and green run light will be flashing along with 1 or 2 of the numbered
lights that are used to indicate the valve's position index. The flashing lights indicate that one of the 22 position indexes can now
be modified using the INC/DEC switch. (For example, if the #1 and #2 light are flashing, position index 1.5 can be adjusted.)
When the ADJUST switch is in the INDEX position, the INC/DEC switch is used to select the position index to be modified. Each
INC or DEC switch entry, changes the position index in 0.5 steps. With the ADJUST switch in the ADJ position, pushing the INC/
DEC switch up or down changes the position of the "selected" valve in 0.1-degree steps. (A valve is "selected" by using Command A-3, Display/Change Selected Valve). If the INC/DEC switch is held in the up or down position for more than 3 seconds, the
valve position is changed in 0.5 degree steps. After moving the valve to the desired position, the Enter button must be pressed to
save the position setting. When the Enter button is pressed, the blinking position index lights (0-9) and command set light 'a' will
momentarily turn off. (See pages 10-30.7-61 through -63 for a complete description of the commissioning procedure.)
In the Position Setup Mode a maximum movement of 8 degrees from the stored position is permitted. When the 8 degree limit or
the min/max travel of the valve is reached, all of the position index lights will momentarily flash on.
Command A-3 displays or changes the "selected" valve for adjustment, system commissioning, or valve diagnostics. If the numbered lights flash momentarily after entering A-3, the command was not executed because the ADJUST switch may be in the
MINIMUM position or the system may be "locked" to prevent tampering.
A-3: Display / Change Selected
Valve
After entering Command A-3, the numbered light of the selected valve (0, 1, 2, or 3) will be turned ON solid. The INC/DEC switch
is then used to change the selected valve. After pressing the INC/DEC switch until the desired valve number is turned ON, press
Enter to save the new selection. When the Enter button is pressed, the selected valve number and command set light 'a' will
momentarily turn off indicating the new selection has been saved.

Table 12: SMARTLINK® MRV User Commands - Command Set ‘A’ (continued)
SMARTLINK® Commands
Number: Name
Description of command purpose and usage
Command Set ‘A’
Command A-4 "commissions" the selected valve and stores the position index (at the time of command entry) as the valve's
maximum "running" position index. Prior to executing A-4, Command A-3 must be performed to verify and/or change the valve
being selected for commissioning. After Command A-2 (Position Set-up Mode) and Command A-4 are executed for each of the
installed valves, the system will follow the 4-20 mA firing rate when the Modulate Valves input is energized on the MRV Interface
Panel (i.e. RI3 of the Control Interface is in the ON state). If a valve is not commissioned, the system will remain at its light-off
positions when modulation is commanded but will indicate an alarm for each non-commissioned valve. The maximum "running"
position index permitted for a commissioned system is the minimum "running" index of the installed valves. The maximum "running" index permits partial commissioning when the lack of a full system load prevents firing the burner to its required capacity.
Therefore, if the user desires operation at position index #9 for maximum application capacity, Command A-4 must be executed
for each installed valve while the system is in Setup Mode and positioned at index #9.
A-4: Commission Valve
Command A-4 is also used to re-commission a valve when its actuator is replaced. (See page 10-30.7-68 for instructions on how
to mechanically replace a valve actuator.) When re-commissioning a spare actuator, the valve number being replaced (#0, 1, 2,
or 3) must be selected with Command A-3 and the replacement actuator must be powered and connected to the control network.
When Command A-4 is executed for re-commissioning, the identification number of the spare valve actuator is saved in the Control Interface and the number of the valve being replaced is saved in the spare actuator. After re-commissioning the spare actuator, the valve should be re-calibrated by MAXON-trained personnel (see Commands C-1 and C-2) and the system must be repowered or reset (using the Remote Reset input or the User Display). Then the burner can be re-lit and the MRV will modulate
based on the 4-20 mA firing rate when commanded. Due to mechanical tolerances, the direct mounting of the replacement actuator will change the position of the valve by less than 1 degree. Burner operation should be re-verified after actuator replacement
if a 1 degree change in absolute valve position could affect burner performance. If an actuator is replaced without executing
Command A-4 for valve re-commissioning, a valve "swap" alarm will be indicated and the system will not modulate based on the
4-20 mA firing rate when commanded.
If the numbered lights flash momentarily after entering Command A-4, the command was not executed for one or more of the following reasons:
- The ADJUST switch may be in the MINIMUM position,
- The system is not in Position Setup Mode (or in Shutdown Mode for actuator re-commissioning),
- The system may be "locked" to prevent tampering, or
- The replacement valve is not connected to the system when re-commissioning a spare actuator.
Command A-5 is used to enter the Valve Position Setup Mode for adjusting the maximum position (index #9 of the selected
valve) and setting a linear position ramp from the minimum to maximum stored positions. If the numbered lights flash momentarily after command entry, the command was not executed for one or more of the following reasons:
- The system is not currently at position index #9,
- The ADJUST switch may be in the MINIMUM position,
- The system is in Shutdown Mode, or
- The system may be "locked" to prevent tampering.
A-5: Set Max Position &
Min/Max Ramp
After entering the command successfully, both the yellow manual light and green run light will be flashing (indicating Position
Setup Mode) along with a flashing #9 light. The selected valve's maximum position can now be modified using the INC/DEC
switch. If the ADJUST switch is in the ADJ position, pushing the INC/DEC switch up or down changes the valve position in +/-0.1
degree steps. If the INC/DEC switch is held in the up or down position for more than 3 seconds, the valve position is changed in
0.5 degree steps. After moving the valve to the desired position, the Enter button must be pressed to save the position setting.
When the Enter button is pressed, the #9 position index light and the command set light 'a' will momentarily turn off. Prior to executing Command A-5, Command A-3 must be performed to verify and/or change the valve being selected for adjustment.
In the Position Setup Mode a maximum movement of 8 degrees from the stored position is permitted. When the 8 degree limit or
min/max travel of the valve is reached, all of the position index lights will momentarily flash on. If the ADJUST switch is in the
INDEX position, valve positioning is inhibited and is indicated by a momentary flash of the position index lights when an INC/DEC
adjustment is attempted. When the system is in Position Setup Mode, the actual valve position is provided as a 4-20 mA output
signal on the OUT+/- terminals of the Control Interface. If a User Display is not purchased, this output can be measured and
recorded in the MRV Commissioning Sheet (Reference Table 16) as an indication of the positions stored in the Control Interface.
A-6: Set Min Position & Min/Max
Ramp
Command A-6 is used to enter the Valve Position Setup Mode for adjusting the minimum position (index #0 of the selected valve)
and setting a linear position ramp from the minimum to maximum positions. To enter Command A-6, the position of the system
must be at index #0. Adjustment of the minimum position is performed identical to adjustment of the maximum position, Command A-5.
A-7: Unlock Valve Configuration
Command A-7 permits entry of a 4-digit passcode to "unlock" the system configuration and position profile for user modification.
A flashing alarm light indicates a "locked" unit. If the alarm light is not flashing, the unit is already unlocked and the numbered
lights will flash momentarily if command entry is attempted. After the command is entered, the INC/DEC command is used to
select a passcode digit as indicated by the lights. Once selected, the Enter button should be pushed and the process repeated 3
more times. If the 4-digit passcode is correct, the alarm light will stop flashing and be turned off if no other alarms exist. To relock the unit, move the command switch to the RUN position.

Table 13: SMARTLINK® MRV User Commands - Command Set ‘B’
Table 13: SMARTLINK® MRV User Commands - Command Set ‘B’
SMARTLINK® Commands
Number: Name
Description of command purpose and usage
Command Set ‘B’
Command B-0 is a configuration command that permits selection of firing rate when a loss of signal event occurs. (A loss of signal condition exists if the 4-20 mA firing rate command signal drops below 0.05 mA). After Command B-0 is entered, the current
configuration is shown by one of the numbered lights. Select an L.O.S. configuration, #0,1,2,3, or 4, using the INC/DEC switch
B-0: Select Loss of Signal (LOS) and push the Enter button after the desired configuration is selected and indicated by the numbered lights.
Position
Configuration #0,1,2, and 3 correspond to the positions defined at index #0, 3, 6, and 9 (max), respectively. Configuration #4 corresponds to no position change (actuator remains in the last firing rate position before loss of signal). The factory default configuration is #0, position index #0.
Command B-1 is used to set a custom purge position that is independent of the maximum position required for high fire burner
operation. In most applications, this command is not required because the maximum position established for each valve at high
fire is acceptable during the purge period. (If this command is not used, purge positions will be set to the same values as stored
for position index #9.)
B-1: Set Purge Position
Prior to executing this command, the system must be in Startup Mode (i.e. Modulate Valve Command input of the MRV Interface
Panel is in OFF state) and the system's Startup Configuration must be set to "Custom". (See Command B-4 for Startup Configuration.) In addition, Command A-3 must also be executed prior to Command B-1 execution in order to verify and/or change the
valve being selected for adjustment. When Command B-1 is executed, the system will enter Position Setup Mode to allow user
modification of the purge position (index #10) of the selected valve. If the numbered lights flash momentarily after entering Command B-1, the command was not executed for one or more of the following reasons:·
- The system is currently in RUN mode (i.e., the Modulate Valves command is energized),
- The ADJUST switch is the MINIMUM position,
- The system is in Shutdown Mode, or
- The system is "locked" to prevent tampering.
After successfully entering Command B-1, both the yellow manual light and green run light on the Control Interface will be flashing
along with numbered lights 9, 0, and 1. The flashing lights indicate that the purge position index can now be modified using the
INC/DEC switch. With the ADJUST switch in the ADJ position, pushing the INC/DEC switch up or down changes the position of
the "selected" valve in 0.1 degree steps. (A valve is "selected" by using Command A-3, Display/Change Selected Valve). If the
INC/DEC switch is held in the up or down position for more than 3 seconds, the valve position is changed in 0.5 degree steps.
After moving the valve to the desired position, the Enter button must be pressed to save the position setting. When the Enter button is pressed, the blinking position index lights (0-9) and command set light 'a' will momentarily turn off.
In the Position Setup Mode a maximum movement of 8 degrees from the stored position is permitted. When the 8 degree limit or
the min/max travel of the valve is reached, all of the position index lights will momentarily flash on. If the ADJUST switch is in the
INDEX position, valve positioning is inhibited and is indicated by a momentary flash of the position index lights when an INC/DEC
adjustment is attempted. When the system is in Position Setup Mode, the actual valve position is provided as a 4-20 mA output
signal on the OUT+/- terminals of the Control Interface. If a User Display is not purchased, this output can be measured and
recorded in the MRV Commissioning Table (Reference Table 16) as an indication of the positions stored in the Control Interface.
B-2: Set Standby Position
Command B-2 is used to set a custom standby position that is independent of the minimum position required for low fire burner
operation. In most applications, this command is not required because the minimum position established for each valve at low fire
is acceptable during the standby period. (If this command is not used, standby positions will be set to the same values as stored
for position index #0.)
After successfully entering Command B-1, both the yellow manual light and green run light on the Control Interface will be flashing
along with numbered lights 9 and 0. Adjustment of the standby positions and the requirements for entering the command are
identical to Command B-1, Set Purge Positions, described above.
Command B-3 is a configuration command that is used to select the deadband placed around the firing rate command input signal. If the input signal contains spurious noise, hunting of the actuators may occur. It is recommended that the source of the
noise is eliminated or the 4-20 mA cable type is verified as well as its shield and ground connections. If the noise cannot be eliminated, the deadband can be increased as a last resort.
B-3: Select Deadband
After Command B-3 is entered, the current configuration is shown by one of the numbered lights. Select a deadband configuration, #0-5, using the INC/DEC switch and push the Enter button after the desired configuration is selected and indicated by the
numbered lights. Configuration #0,1,2,3,4 and 5 correspond to a deadband of 0, 0.03, 0.06, 0.13, 0.16%, respectively. The factory default configuration is #2, 0.06%.

Table 13: SMARTLINK® MRV User Commands - Command Set ‘B’ (continued)
SMARTLINK® Commands
Number: Name
Description of command purpose and usage
Command Set ‘B’
Command B-4 permits selection of the Startup Configuration setting. The Startup Configuration setting defines what effect each
startup command input has on SMARTLINK® MRV operation. The 3 startup commands include the Purge Position Command
(PPC), Light-off Position Command (LPC), and Standby Position Command (SPC). The SPC command is active when both the
PPC and LPC command inputs are not energized. All startup commands are overridden by the Modulate Valves command
(MVC) which puts the MRV in RUN mode. The two configuration options are defined as follows:
B-4: Select Startup Configuration
Default Startup (Setting #0): PPC = maximum position for all valves, index #9; LPC = minimum position for all valves, index #0;
SPC = minimum position, index #0. For this configuration setting, adjustment of the minimum position (Index #0) and maximum
position (Index #9) will automatically change the purge (Index #10), light-off (Index #10.5), and standby (Index #9.5) positions.
Custom Startup (Setting #1): For each valve, the user can define a position for each of the startup commands (PPC, LPC, SPC).
This configuration setting enables Command B-1 (Set Purge Position), Command B-2 (Set Standby Position), and Command B5 (Set Light-Off Position) and enables (or disables) custom startup positions for standby, purge, and light-off states during the
burner startup sequence controlled by the user's burner management system.
After Command B-4 is entered, the current configuration is shown by one of the numbered lights. Select Startup Configuration #0
(Default Startup) or #1 (Custom Startup), using the INC/DEC switch and push the Enter button after the desired configuration is
selected and indicated by the numbered lights. The factory default Startup Configuration is setting #0, Default Startup.
B-5: Set Light-Off Position
Command B-5 is used to set a custom light-off position that is independent of the minimum position required for low fire burner
operation. In most applications, this command is not required because the minimum position established for each valve at low
fire is also acceptable for burner light-off positions. (If this command is not used, light-off positions will be set to the same values
as stored for position index #0.)
After successfully entering Command B-5, both the yellow manual light and green run light on the Control Interface will be flashing along with numbered lights 9 and 1. Adjustment of the light-off positions and the requirements for entering the command are
identical to Command B-1, Set Purge Positions, described above.
Command B-6 is a configuration command that is used to set on or off the automatic ramp function. The factory default is Auto
Ramp ON, configuration #1. Configuration #0 is Auto Ramp OFF.
After command entry, the current configuration is shown by one of the numbered lights. Select Auto Ramp ON, #1, or Auto Ramp
OFF, #0 using the INC/DEC switch and push the Enter button after the desired configuration is selected and indicated by the
B-6: Select Auto Ramp Adjust On/
numbered light.
Off
The automatic ramp function is used during the Position Setup Mode to create a linear position ramp between the position being
adjusted and the two adjacent position indexes. This provides a position "smoothing" of the valve profile and simplifies commissioning because only 10 position indexes (i.e. index 0, 1, 2, 3, ….instead of 0, 0.5, 1.0, 1.5, etc.) require adjustment. For burner
tuning that requires precision adjustment of each of the 19 position indexes, the Auto Ramp function should be OFF.
B-7: Select Movement
Configuration
Command B-7 is a configuration command that is used to select valve movement speed during RUN mode when modulating
from low to high fire. Configuration setting #0 is the slow speed (~60 seconds), setting #1 the medium speed (~40 seconds), and
setting #2 is the fast speed (~20 seconds). Configuration setting #1, medium speed, is the default configuration.
After command entry, the current configuration is shown by one of the numbered lights. Select the movement configuration (#0,
#1, or #2) using the INC/DEC switch and push the Enter button after the desired configuration is selected and indicated by the
numbered lights.

Description of command purpose and usage
Command Set ‘C’
C-0: Test Valve
Command C-0 is a diagnostic command that is used to test a valve actuator through its full travel. When the command is executed, the selected valve moves to its full open position, pauses for several seconds, and returns to a fully closed position. (To
display or change the selected valve, perform Command A-3.) During command execution, the even numbered lights should
flash on the Control Interface. If either open or close positions are not properly reached, all the numbered lights will flash momentarily indicating the test has failed. The system must first be in Shutdown Mode before this command will be executed. (To place
the system in Shutdown Mode, disconnect one of the valves temporarily until a Shutdown alarm is indicated or initiate a system
shutdown from the User Display.) If all of the numbered lights momentarily flash after command entry, the command was not executed.
C-1: Reserved for Trained
Personnel
(Enable Calibration)
Command C-1 permits the selected valve actuator to be re-calibrated. In effect, this command enables the user to execute Command C-2, Calibrate Valve. (Refer to the Actuator Replacement section on page 10-30.7-68 for the complete procedure.) The
system must first be in Shutdown Mode before this command will be executed. If all of the numbered lights momentarily flash
after Control Interface Command entry, the command was not executed.
C-2: Reserved for Trained
Personnel
(Calibrate Valve)
Command C-2 calibrates the valve actuator and replaces the factory-set valve calibration data. This command should be performed by factory-trained personnel only. When the command is executed, the selected valve finds the factory-set hard-stop,
establishes a new "home" or 0.0 degree position, and then verifies full travel movement in 0.1 degree steps. (To display or
change the selected valve prior to executing Command C-2, execute Command A-3.) When the command is executed from the
Control Interface, the even numbered lights should flash. (No lights will flash on the Control Interface if this command is executed
from the User Display.) The command takes approximately 3 minutes to complete. If the calibration procedure fails, all the numbered lights will flash momentarily indicating the test has failed. Command C-1 must be successfully performed before this command can be executed. If all of the numbered lights momentarily flash after the command is entered or at the end of the
calibration procedure, the command was not successfully executed.
C-3: Reset Factory Default
Settings
Command C-3 is a configuration command that is used to reset all system configuration and valve position data with the exception of the backup position profile. To execute Command C-3, the valve system must first be in Position Setup Mode (See Command A-2) and the Modulate Valve Command (MVC) must be off. With the unit in Position Setup Mode and Command C-3
selected, push the Enter button. Light #3 and the command set 'c' light should momentarily turn off indicating the reset is complete.
Command C-4 is a configuration command that is used to enter a new 4-digit electronic passcode to prevent tampering. To execute Command C-4, the electronic "lock" must be enabled and the unit must be in the "unlocked" state. (A locked unit is indicated
by a flashing alarm light.) If all the numbered lights momentarily flash after command entry, the command was not executed due
to one of the following reasons:
- The "lock" function is disabled, or
- The unit is currently locked. (See Command C-5 to enable the lock function or Command A-7 to unlock the unit.)
C-4: Enter New Lock Combination
After the command is entered, the INC/DEC command is used to select a passcode digit as indicated by the numbered lights.
After the first digit is selected, the Enter button should be pushed and the numbered light and command set light 'c' momentarily
turn off. Repeat the previous digit entry process 3 more times for a total of 4 digits. After the 4th digit is entered, the number #4
light will turn on and the command set 'c' light will begin to flash, indicating that a new 4-digit passcode has been saved and the
command is complete.
If the 4-digit passcode is forgotten, call MAXON for assistance. The factory default 4-digit passcode is 0-0-0-0.
Command C-5 is a configuration command that is used to enable or disable the electronic "lock" function. The factory default is
configuration #0, Lock Disable. Configuration #1 is Lock Enable.
C-5: Select Lock Enable / Disable To execute Command C-5, the unit must be in the unlocked state. (The alarm light will be flashing rapidly if the unit is locked. See
Command A-7 to unlock the device.) After command entry, the current configuration is shown by one of the numbered lights.
Select either configuration #0 or #1 using the INC/DEC switch and push the Enter button after the desired configuration is
selected and indicated by the numbered lights.
C-6: Save Profile as Backup
Command C-6 is a configuration command that is used to save the currently stored valve position profiles. This command is
used in conjunction with C-7, Restore Backup Profile, to help ensure that proven valve position profiles can be restored without
re-commissioning if a factory default reset is accidentally performed or incorrect position adjustments are made during the commissioning process.
To execute Command C-6, the valve system must first be in Position Setup Mode (See Command A-2). With Command C-6
selected and the unit in Position Setup Mode, push the Enter button. Light #6 and the command set 'c' light should momentarily
turn off, indicating the command has been executed.
C-7: Restore Backup Profile
Command C-7 is a configuration command that is used to restore a backup valve position profile as the current operating profile.
This command is used in conjunction with C-6, Save Profile as Backup, to help ensure that proven valve position profiles can be
restored without re-commissioning if a factory default reset is accidentally performed or incorrect position adjustments are made
during the commissioning process.
To execute Command C-7, the valve system must first be in Position Setup Mode (See Command A-2) and the Modulate Valve
command input must be in the OFF state. With the unit in Position Setup Mode and Command C-7 selected, push the Enter button. Light #7 and the command set 'c' light should momentarily turn off, indicating the command has been executed.
