features that allow state-of-the-art commercial building control. Each controller is programmable and configurable through software.
The Spyder Lon controllers require the Spyder Programmable
Feature to be licensed in the WEBpro workbench tool and the
WEBS AX JACE Controller for programming and downloading. The eight Spyder Lon Models are also available as Individually Licensed Controllers (ILC). The ILC versions are identical in design and capability in every detail except for the licensing. The Individual Licensing of the Spyder ILCs
(The License is built in) allows them to be programmed and downloaded with any brand of the Niagara Workbench or
JACE controller. The Spyder ILCs are identified with a suffix on the Part Number of -ILC. Example: PUL6438S-ILC follows all the same Installation Instructions information as the
PUL6438S.
These controllers are for use in VAV (Variable Air Volume) and
Unitary HVAC control applications. Each controller contains a host micro controller to run the main HVAC application and a second micro controller for L

BEFORE INSTALLATION
The controller is available in eight models (see Table 1).
Review the power, input, and output specifications on page 3
before installing the controller.
— Hardware driven by Triac outputs must have a minimum current draw, when energized, of 25 mA and a maximum current draw of 500 mA.
63-2685—03
SPYDER® LON PROGRAMMABLE, VAV/UNITARY CONTROLLERS
— Hardware driven by the analog current outputs must have a maximum resistance of 550 Ohms, resulting in a maximum voltage of 11 volts when driven at 20 mA. If resistance exceeds 550 Ohms, voltages up to 18 Vdc are possible at the analog output terminal.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property damage.
Disconnect power supply before beginning wiring or making wiring connections to prevent electrical shock or equipment damage.
INSTALLATION
The controller must be mounted in a position that allows clearance for wiring, servicing, removal, connection of the
LonWorks® Bus Jack, and access to the Neuron® Service Pin
(see Fig. 16 and Fig. 17 on page 14).
The controller may be mounted in any orientation.
IMPORTANT
Avoid mounting in areas where acid fumes or other deteriorating vapors can attack the metal parts of the controller, or in areas where escaping gas or other explosive vapors are present. Fig. 4–Fig. 7 on page 6 for mounting dimensions.
For PVL0000AS, PVL4022AS, and PVL6436AS models, the actuator is mounted first and then the controller is mounted.
For the other models, go to “Mount Controller” on page 5 to
begin the installation.
Mount Actuator onto Damper Shaft
(PVL0000AS, PVL4022AS, and
PVL6436AS)
PVL0000AS, PVL4022AS, and PVL6436AS controllers include the direct-coupled actuator with Declutch mechanism, which is shipped hard-wired to the controller.
The actuator mounts directly onto the VAV box damper shaft and has up to 44 lb-in. (5 Nm) torque, 90-degree stroke, and
90 second timing at 60 Hz. The actuator is suitable for mounting onto a 3/8 to 1/2 in. (10 to 13 mm) square or round
VAV box damper shaft. The minimum VAV box damper shaft length is 1-9/16 in. (40 mm).
The two mechanical end-limit set screws control the amount of rotation from 12° to 95°. These set screws must be securely fastened in place. To ensure tight closing of the damper, the shaft adapter has a total rotation stroke of 95° (see Fig. 1).
NOTES:
1.
2.
The actuator is shipped with the mechanical endlimit set screws set to 95 degrees of rotation.
Adjust the two set screws closer together to reduce the rotation travel. Each “hash mark” indicator on the bracket represents approximately 6.5° of rotation per side.
The Declutch button, when pressed, allows you to rotate the universal shaft adapter (see Fig. 1).
IMPORTANT
Determine the damper rotation and opening angle prior to installation. See Fig. 2 and 3 for examples.

SPYDER® LON PROGRAMMABLE, VAV/UNITARY CONTROLLERS
Before mounting the actuator onto the VAV box damper shaft, determine the following:
1.
Determine the damper shaft diameter. It must be between 3/8 in. and 1/2 in. (10 to 13 mm).
2.
Determine the length of the damper shaft. If the length of the VAV box damper shaft is less than 1-9/16 in.
(40 mm), the actuator cannot be used.
3.
Determine the direction the damper shaft rotates to open the damper (CW or CCW) (see Fig. 3). Typically, there is an etched line on the end of the damper shaft that indicates the position of the damper. In Fig. 2, the indicator shows the damper open in a CW direction.
4.
Determine the damper’s full opening angle (45, 60, or 90 degrees). In Fig. 2, the damper is open to its full open position of 90 degrees.

Mounting Actuator Onto Damper Shaft
(PVL0000AS, PVL4022AS, and PVL6436AS )
The unit is shipped with the actuator set to rotate open in the clockwise (CW) direction to a full 95 degrees. The extra 5 degrees ensures a full opening range for a 90 degree damper.
The installation procedure varies depending on the damper opening direction and angle:
1.
If the damper rotates clockwise (CW) to open, and the angle of the damper open-to-closed is 90 degrees: a. Manually open the damper fully (rotate clockwise). b. Using the Declutch button, rotate the universal shaft adapter fully clockwise. c. Mount the actuator to the VAV damper box and shaft. d. Tighten the two bolts on the centering clamp
(8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
When the actuator closes, the damper rotates CCW
90 degrees to fully close.
2.
If the damper rotates clockwise (CW) to open, and the angle of the damper open-to-closed is 45 or 60 degrees: a. Manually open the damper fully (rotate clockwise).
b. The actuator is shipped with the mechanical end-limits set at 95 degrees. Adjust the two mechanical end-limit set screws to provide the desired amount of rotation. Adjust the two set screws closer together to reduce the rotation travel.
c. Tighten the two mechanical end-limit screws (Phillips
#2 screwdriver; (26.5–31 lb-in. [3.0–3.5 Nm] torque).
d. Using the Declutch button, rotate the universal shaft adapter fully clockwise. e. Mount the actuator to the VAV damper box and shaft. f. Tighten the two bolts on the centering clamp
(8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
5 g. When the actuator closes, the damper rotates CCW either 45 or 60 degrees to fully close.
3.
If the damper rotates counterclockwise (CCW) to open, and the angle of the damper open-to-closed is 90 degrees: a. Manually open the damper fully (rotate counterclockwise).
b. Using the Declutch button, rotate the universal shaft adapter fully counterclockwise. c. Mount the actuator to the damper box and shaft. d. Tighten the two bolts on the centering clamp (8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque). When the actuator closes, the damper rotates CW
90 degrees to fully close.
4.
If the damper rotates counterclockwise to open, and the angle of the damper open-to-closed is 45 or 60 degrees: a. Manually open the damper fully (rotate counterclockwise).
b. The actuator is shipped with the mechanical end-limits set at 95 degrees. Adjust the two mechanical end-limit set screws to provide the desired amount of rotation. Adjust the two set screws closer together to reduce the rotation travel.
c. Tighten the two mechanical end-limit screws
(Phillips #2 screwdriver; (26.5–31 lb-in. [3.0–3.5 Nm] torque).
d. Using the Declutch button, rotate the universal shaft adapter fully counterclockwise. e. Mount the actuator to the VAV damper box and shaft. f. Tighten the two bolts on the centering clamp
(8 mm wrench; 70.8–88.5 lb-in. [8–10 Nm] torque).
g. When the actuator closes, the damper rotates CW either 45 or 60 degrees to fully close.
IMPORTANT
Special precautions must be taken for dampers that open in a CCW direction. The actuator is shipped with its rotation direction set to CW to Open, which applies to the damper direction in steps 1 and 2 above. If the damper shaft rotates in the CCW direction to open, the controller software must be programmed to change the rotation to “Reverse to Open,” which applies to the damper direction in steps 3 and 4 above.
IMPORTANT
It is advisable to leave the dampers in an open position after installation to avoid the possibility of over-pressurizing the duct work on fan startup. Use the Declutch button (see Fig. 1 on page 4) to open the box damper on controllers that are powered down, to prevent over-pressurization in the duct work on fan startup. To Declutch, press and hold the button to disengage the motor. Turn the damper shaft until the damper is open and release the button. When power is restored to the controller, the controller synchronizes the damper actuator, so that the damper is in the correct position upon startup.
Mount Controller
NOTE: The controller may be wired before mounting to a panel or DIN rail.
Terminal blocks are used to make all wiring connections to the controller. Attach all wiring to the appropriate terminal blocks
See Fig. 4–Fig. 7 for panel mounting dimensions. See Fig. 8 on page 7 for DIN rail mounting.

Panel Mounting
The controller enclosure is constructed of a plastic base plate
63-2685—03 6 and a plastic factory-snap-on cover.
SPYDER® LON PROGRAMMABLE, VAV/UNITARY CONTROLLERS
NOTE: The controller is designed so that the cover does not need to be removed from the base plate for either mounting or wiring.
The controller mounts using four screws inserted through the corners of the base plate. Fasten securely with four No. 6 or
No. 8 machine or sheet metal screws.
The controller can be mounted in any orientation. Ventilation openings are designed into the cover to allow proper heat dissipation, regardless of the mounting orientation.
DIN Rail Mounting (PUL1012S, PUL4024S,
PUL6438S, PVL4024NS, and PVL6438NS)
To mount the PUL1012S, PUL4024S, PUL6438S,
PVL4024NS, or PVL6438NS controller on a DIN rail [standard
EN50022; 1-3/8 in. x 9/32 in. (7.5 mm x 35 mm)], refer to Fig. 8 and perform the following steps:
1.
Holding the controller with its top tilted in towards the
DIN rail, hook the two top tabs on the back of the controller onto the top of the DIN rail.
2.
Push down and in to snap the two bottom flex connectors of the controller onto the DIN rail.
IMPORTANT
To remove the controller from the DIN rail, perform the following:
1. Push straight up from the bottom to release the top tabs.
2. Rotate the top of the controller out towards you and pull the controller down and away from the DIN rail to release the bottom flex connectors.
TOP TABS
— Use 1/4 inch (6 mm) outside diameter, with a 0.040 in. (1 mm) wall thickness, plenum-rated 1219 FR
(94V-2) tubing.
— Always use a fresh cut on the end of the tubing that connects to the air flow pickups and the restrictor ports on the controller.
Connect the high pressure or upstream tube to the plastic restrictor port labeled ( + ), and the low pressure or downstream tube to the restrictor port labeled ( ). See labeling in Fig. 9.
When twin tubing is used from the pickup, split the pickup tubing a short length to accommodate the connections.
NOTES:
— If controllers are mounted in unusually dusty or dirty environments, an inline, 5-micron disposable air filter (use 5-micron filters compatible with pneumatic controls) is recommended for the high pressure line (marked as + ) connected to the air flow pickup.
— The tubing from the air flow pickup to the controller should not exceed three feet (0.914 m). Any length greater than this will degrade the flow sensing accuracy.
— Use caution when removing tubing from a connector. Always pull straight away from the connector or use diagonal cutters to cut the edge of the tubing attached to the connector. Never remove by pulling at an angle.

Power
Before wiring the controller, determine the input and output device requirements for each controller used in the system.
Select input and output devices compatible with the controller and the application. Consider the operating range, wiring requirements, and the environment conditions when selecting input/output devices. When selecting actuators for modulating applications consider using floating control. In direct digital control applications, floating actuators will generally provide control action equal to or better than an analog input actuator for lower cost.
Determine the location of controllers, sensors, actuators and other input/output devices and create wiring diagrams. Refer to
Fig. 19 to Fig. 25 beginning on page 16 for illustrations of typical controller wiring for various configurations.
7 63-2685—03
SPYDER® LON PROGRAMMABLE, VAV/UNITARY CONTROLLERS
The application engineer must review the control job requirements. This includes the sequences of operation for the controller, and for the system as a whole. Usually, there are variables that must be passed between the controller and other
Spyder Lon controller(s) that are required for optimum systemwide operation. Typical examples are the TOD, Occ/Unocc signal, the outdoor air temperature, the demand limit control signal, and the smoke control mode signal.
It is important to understand these interrelationships early in the job engineering process, to ensure proper implementation when configuring the controllers. Refer to the controller
Application Guides.
Power Budget
A power budget must be calculated for each device to determine the required transformer size for proper operation. A power budget is simply the summing of the maximum power draw ratings (in VA) of all the devices to be controlled. This includes the controller itself and any devices powered from the controller, such as equipment actuators (ML6161 or other motors) and various contactors and transducers.
IMPORTANT
• If a controller is used on Heating and Cooling Equipment (UL 1995, U.S. only) and transformer primary power is more than 150 volts, connect the transformer secondary common to earth ground (see Fig. 12 on page 10).
• When multiple controllers operate from a single transformer, connect the same side of the transformer secondary to the same power input terminal in each device. The earth ground terminal (terminal 3) must be connected to a verified earth ground for each controller in the group (see Fig. 13 on page 11).

The system example above requires 30.7 VA of peak power.
Therefore, a 100 VA AT92A transformer could be used to power one controller of this type. Because the total peak power
63-2685—03 8 is less than 33 VA, this same transformer could be used to power three of these controllers and meet NEC Class 2 restrictions (no greater than 100 VA).

For contactors and similar devices, the in-rush power ratings should be used as the worst case values when performing power budget calculations. Also, the application engineer must consider the possible combinations of simultaneously energized outputs and calculate the VA ratings accordingly.
The worst case, which uses the largest possible VA load, should be determined when sizing the transformer.
Each controller requires 24 Vac power from an energy-limited
Class II power source. To conform to Class II restrictions (U.S. only), transformers must not be larger than 100 VA. A single transformer can power more than one controller.
GUIDELINES FOR POWER WIRING ARE AS FOLLOWS:
— For multiple controllers operating from a single transformer, the same side of the transformer secondary must be connected to the same power input terminal in each device. The earth ground terminal must be connected to a verified earth ground for each controller in the group (see Fig. 13 on page 11).
Controller configurations are not necessarily limited to three devices, but the total power draw, including accessories, cannot exceed 100 VA when powered by the same transformer (U.S. only).
— See Fig. 12 on page 10 for controller power wiring used in UL 1995 equipment (U.S. only).
— Many controllers require all loads to be powered by the same transformer that powers the controller.
— Keep the earth ground connection wire run as short as possible (refer to Fig. 11–Fig. 13 beginning on page 10).
— Do not connect earth ground to the controller’s digital or analog ground terminals (refer to Fig. 11 and Fig.
13).
SPYDER® LON PROGRAMMABLE, VAV/UNITARY CONTROLLERS
— Unswitched 24 Vac power wiring can be run in the same conduit as the L ON W ORKS ® Bus cable.
— Maintain at least a 3 in. (76 mm) separation between
Triac outputs and L ON W ORKS ® Bus wiring throughout the installation.
Line-Loss
Controllers must receive a minimum supply voltage of 20 Vac.
If long power or output wire runs are required, a voltage drop due to Ohms Law (I x R) line-loss must be considered. This line-loss can result in a significant increase in total power required and thereby affect transformer sizing. The following example is an I x R line-loss calculation for a 200 ft. (61m) run from the transformer to a controller drawing 37 VA and using two 18 AWG (1.0 sq mm) wires.
The formula is:
Loss = [length of round-trip wire run (ft.)] x [resistance in wire (ohms per ft.)] x [current in wire (amperes)]
From specification data:
18 AWG twisted pair wire has a resistance of 6.52 ohms per
1000 feet.
Loss = [(400 ft.) x (6.52/1000 ohms per ft.)] x [(37 VA)/(24V)]
= 4.02 volts
This means that four volts are going to be lost between the transformer and the controller. To assure the controller receives at least 20 volts, the transformer must output more than 24 volts. Because all transformer output voltage levels depend on the size of the connected load, a larger transformer outputs a higher voltage than a smaller one for a given load.
Fig. 10 shows this voltage load dependence.
In the preceding I x R loss example, even though the controller load is only 37 VA, a standard 40 VA transformer is not sufficient due to the line-loss. Looking at Fig. 10, a 40 VA transformer is just under 100 percent loaded (for the 37 VA controller) and has a secondary voltage of 22.9 volts. (Use the lower edge of the shaded zone in Fig. 10 that represents the worst case conditions.) When the I x R loss of four volts is subtracted, only 18.9 volts reaches the controller. This is not enough voltage for proper operation.
In this situation, the engineer has three alternatives:
1.
Use a larger transformer. For example, if an 80 VA model is used, an output of 24.4 volts, minus the four volt lineloss, supplies 20.4V to the controller (see Fig. 10).
Although acceptable, the four-volt line-loss in this example is higher than recommended.
IMPORTANT
No installation should be designed where the line-loss is greater than two volts. This allows for nominal operation if the primary voltage drops to 102 Vac (120 Vac minus 15 percent).
2.
Use heavier gauge wire for the power run. 14 AWG
(2.0 sq mm) wire has a resistance of 2.57 ohms per
1,000 ft. Using the preceding formula results in a lineloss of only 1.58 volts (compared with 4.02 volts). This would allow a 40 VA transformer to be used. 14 AWG
(2.0 sq mm) wire is the recommended wire size for 24
Vac wiring.
3.
Locate the transformer closer to the controller. This reduces the length of the wire run, and the line-loss.
The issue of line-loss is also important in the case of the output wiring connected to the Triac digital outputs. The same formula and method are used. Keep all power and output wire runs as short as practical. When necessary, use heavier gauge wire, a bigger transformer, or install the transformer closer to the controller.
To meet the National Electrical Manufacturers Association
(NEMA) standards, a transformer must stay within the NEMA limits. The chart in Fig. 10 shows the required limits at various loads.
With 100 percent load, the transformer secondary must supply between 23 and 25 volts to meet the NEMA standard. When a purchased transformer meets the NEMA standard DC20-1986, the transformer voltage regulating ability can be considered reliable. Compliance with the NEMA standard is voluntary.

WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property damage.
Disconnect power supply before beginning wiring or making wiring connections, to prevent electrical shock or equipment damage.
NOTES:
— For multiple controllers operating from a single transformer, the same side of the transformer secondary must be connected to the same power input terminal in each controller. Controller configurations will not necessarily be limited to three devices, but the total power draw, including accessories, cannot exceed 100 VA when powered by the same transformer (U.S. only). For
power and wiring recommendations, See “Power” on page 7. The earth ground terminal (terminal 3)
must be connected to a verified earth ground for each controller in the group (see Fig. 13 on page 11).
— All loads on the controller must be powered by the same transformer that powers the controller itself.
A controller can use separate transformers for controller power and output power.
— Keep the earth ground connection (terminal 3) wire run as short as possible.
— Do not connect the universal input COM terminals, analog output COM terminals or the digital input/ output COM terminals to earth ground. Refer to
Fig. 18–Fig. 23 beginning on page 15 for wiring examples.
The 24 Vac power from an energy limited Class II power source must be provided to the controller. To conform to Class
II restrictions (U.S. only), the transformer must not be larger than 100 VA.
Fig. 11 depicts a single controller using one transformer.
IMPORTANT
Power must be off prior to connecting to or removing connections from the 24 Vac power (24 Vac/24 Vac
COM), earth ground (EGND), and 20 Vdc power (20
Vdc) terminals.
IMPORTANT
Use the heaviest gauge wire available, up to 14 AWG
(2.0 sq mm), with a minimum of 18 AWG (1.0 sq mm), for all power and earth ground wiring.
Screw-type terminal blocks are designed to accept up to one 14 AWG (2.0 sq mm) conductor or up to two 18
AWG (1.0 sq mm) conductors. More than two wires that are 18 AWG (2.0 sq mm) can be connected with a wire nut. Include a pigtail with this wire group and attach the pigtail to the terminal block.
IMPORTANT
If the controller is used on Heating and Cooling
Equipment (UL 1995, U.S. only) and the transformer primary power is more than 150 volts, connect terminal 2, (the 24 Vac common [24 VAC COM] terminal) to earth ground (see Fig. 12). For these applications, only one controller can be powered by each transformer.
NOTES:
— Unswitched 24 Vac power wiring can be run in the same conduit as the L ON W ORKS ® cable.
— Maintain at least a 3 in. (7.6 cm) separation between Triac outputs and L ON W ORKS ® wiring throughout the installation.

Communications
Refer to “L ON W ORKS ® Wiring Guidelines,” form 74-2865, for a complete description of L ON W ORKS ® Bus network topology rules and approved cable types.
Honeywell provided cable types for L ON W ORKS ® Bus communications wiring are Level IV 22 AWG (0.34 sq mm) plenum or non-plenum rated unshielded, twisted pair, stranded conductor wire.
• For non-plenum areas, U.S. part AK3798 (single-pair stranded) can be used.
• In plenum areas, U.S. part AK3797 (single-pair stranded) or
U.S. part AK3799 (two-pair stranded) can be used.
Contact Echelon Corp. Technical Support for the recommended vendors of Echelon approved cables.
Communications wiring can be run in a conduit, if needed, with non-switched 24 Vac or sensor wiring. If a longer L ON W ORKS ®
Bus network is required, a Q7751A,B router (configured as a repeater) can be added to extend the length of the
L ON W ORKS ® Bus. Each network segment can have a maximum of one repeater.
Pull the cable to each controller on the L ON W ORKS ® Bus and connect to the controller’s communication terminals 7 and 8.
(See Table 6 on page 13 and Table 7 on page 13, and Fig. 16 on page 14 for location of terminals 7 and 8.)
NOTE: Connection for operator access to the L ON W ORKS ®
Bus is provided by plugging the Serial L ON T ALK ®
Adapter (SLTA) connector into the L ON W ORKS ® Bus jack (see Fig. 16 on page 14).
IMPORTANT
Notes on communications wiring:
• All field wiring must conform to local codes and ordinances (or as specified on installation drawings).
• Do not bundle device output wires with sensor, digital input or communications L ON W ORKS ® Bus wires.
• Do not use different wire types or gauges on the same L ON W ORKS Bus segment. The step change in line impedance characteristics causes unpredictable reflections on the L ON W ORKS ® Bus.
• In noisy (high EMI) environments, avoid wire runs parallel to noisy power cables, motor control centers, or lines containing lighting dimmer switches. Keep at least 3 in. (76 mm) of separation between noisy lines and the L ON W ORKS ® Bus cable.
• The theoretical limit for each L ON W ORKS ® Bus segment is 60 controllers. Up to 120 controllers can be configured when a repeater is used, and the bus must be either singly or doubly terminated. Actual installations may have a lower limit depending on the devices connected.
• The singly terminated bus must have one 209541B
FTT Termination Module for T tap or Star configurations.
• The doubly terminated bus must have two 209541B
FTT Termination Modules, one at each end of the daisy chain (Bus style) wiring run. Note that the
Q7751A,B router (configured as a repeater) has onboard terminating networks that can be jumper- selected on each segment.
• Make sure that neither of the L ON W ORKS ® Bus wires are grounded.
NOTE: If a 209541B Termination Module is required at the controller, connect two of the three termination module wires to the L ON W ORKS ® Bus terminals 7 and
8, which are labeled Net-1 and Net-2, on the controller. Selecting the appropriate two wires depends on the L ON W ORKS ® Bus network topology.
Refer to the “L ON W ORKS ® Bus Wiring Guidelines,” form 74-2865, and the “FTT Termination Module
Installation Instructions,” form 95-7554. For example, on a doubly terminated daisy-chained bus topology, where controllers are on either end of an L ON W ORKS ®
Bus wire run, mount the termination module on the appropriate terminals, as shown in Fig. 14.

WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property damage.
Disconnect power supply before beginning wiring, or making wiring connections, to prevent electrical shock or equipment damage.
NOTE: When attaching two or more wires to the same terminal, other than 14 AWG (2.0 sq mm), be sure to twist them together. Deviation from this rule can result in improper electrical contact (see Fig. 15).
Each terminal can accommodate the following gauges of wire:
— Single wire: from 22 AWG to 14 AWG solid or stranded
— Multiple wires: up to two 18 AWG stranded, with 1/4 watt wire-wound resistor
Prepare wiring for the terminal blocks, as follows:
1.
Strip 1/2 in. (13 mm) insulation from the conductor.
2.
Cut a single wire to 3/16 in. (5 mm). Insert the wire in the required terminal location and tighten the screw.
3.
If two or more wires are being inserted into one terminal location, twist the wires together a minimum of three turns before inserting them (see Fig. 15).
4.
Cut the twisted end of the wires to 3/16 in. (5 mm) before inserting them into the terminal and tightening the screw.
5.
Pull on each wire in all terminals to check for good mechanical connection.

IMPORTANT
If the controller is not connected to a good earth ground, the controller's internal transient protection circuitry is compromised and the function of protecting the controller from noise and power line spikes cannot be fulfilled. This could result in a damaged circuit board and require replacement of the controller.
Refer to installation diagrams for specific wiring.

CHECKOUT
Step 1. Check Installation and Wiring
Inspect all wiring connections at the controller terminals, and verify compliance with installation wiring diagrams. If any wiring changes are required, first be sure to remove power from the controller before starting work. Pay particular attention to:
— 24 Vac power connections. Verify that multiple controllers being powered by the same transformer are wired with the transformer secondary connected to the same input terminal numbers on each controller. Use a meter to measure 24 Vac at the appropriate terminals (see Fig. 13 on page 11). Controller configurations are not necessarily limited to three devices, but the total power draw, including accessories, cannot exceed 100 VA when powered by the same transformer (U.S. only).
— Be sure that each controller has terminal 3 wired to a verified earth ground, using a wire run as short as possible with the heaviest gauge wire available, up to 14 AWG (2.0 sq mm) with a minimum of 18 AWG (1.0 sq mm) for each controller in the group (see Fig. 13 on page 11).
— Verify that Triac wiring of the digital outputs to external devices uses the proper load power and 24 Vac common terminal (digital output common terminals) for High-Side switching.
NOTE: All wiring must comply with applicable electrical codes and ordinances or as specified on installation wiring diagrams.
For guidelines for wiring run lengths and power budget, see
VERIFY TERMINATION MODULE PLACEMENT (MULTIPLE
CONTROLLERS ONLY)
The installation wiring diagrams should indicate the locations for placement of the 209541B termination module(s). See
Fig. 14 on page 12 and refer to the “L ON W ORKS ® Bus Wiring
Guidelines,” form 74-2865, and the “FTT Termination Module
Installation Instructions,” form 95-7554.
Correct placement of the termination module(s) is required for proper L ON W ORKS ® Bus communications.

CAUTION
Equipment Damage Hazard.
Can cause controller damage or failure.
Do not use any metal object to press the N EURON ®
Service Pin. Use a plastic rod or wood device (such as a pencil with the lead broken off) to press the pin. Using a metal object can damage the circuitry of the controller.
CONTROLLER STATUS LED:
The LED on the front of the controller provides a visual indication of the status of the device. When the controller receives power, the LED appears in one of the following allowable states, as described in Table 8.

CONTROLLER REPLACEMENT
There are no serviceable or repairable parts inside the controller.
WARNING
Fire, Explosion, or Electrical Shock Hazard.
Can cause severe injury, death or property damage.
Do not attempt to modify the physical or electrical characteristics of this device in any way. Replace the controller if troubleshooting indicates a malfunction.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property damage.
Disconnect power supply before beginning controller replacement to prevent electrical shock or equipment damage.
Terminal Block Removal
To simplify controller replacement, all terminal blocks are designed to be removed with the wiring connections intact and then re-installed on the new controller. See Fig. 26 and refer to the following procedure:
IMPORTANT
To prevent bending or breaking the alignment pins on longer terminal blocks, insert the screwdriver at several points to evenly and gradually lift up the terminal block.
Insert the screwdriver blade no more than 1/8 in.
(3 mm) to prevent damage to the terminal block alignment pins on the controller circuit board.
SHORT TERMINAL BLOCK LONGTERMINAL BLOCK
M23563
Fig. 26. Removing Terminal Blocks.
1.
Use a thin-bladed screwdriver to evenly raise the terminal block from its alignment pins: a. For short terminal blocks (1 to 5 terminals), insert screwdriver blade in the center of the terminal block and use a back and forth twisting motion to gently raise the terminal block from its alignment pins 1/4 in.
(6.35 mm).
b. For long terminal blocks (6 or more terminals), insert screwdriver blade on one side of the terminal block and gently rotate the blade 1/4 turn. Then, move to the other side of the terminal block and do the same.
Repeat until the terminal block is evenly raised 1/4 in. (6.35 mm) from its alignment pins.
2.
Once the terminal block is raised 1/4 in. (6.35 mm) from its alignment pins, grasp the terminal block at its center
(for long terminal blocks grasp it at each end) and pull it straight up.
Controller Replacement (PVL0000AS,
PVL4022AS, and PVL6436AS)
