Good Wiring
Practices
Separate wire into bundles—When planning the system wiring,
separate wiring into functionally similar bundles, e.g.
• Power leads
• Sensor leads (if power leads must cross sensor leads, they should
cross at a 90° angle)
• Output signal lines
Separate sources of electrical noise—Locate all sources of electrical
noise in your system, and separate these sources from the control
system, e.g.
• Motors
• Contacts
• Solenoids
Electrical noise can affect the function of any control system. When
driving a contactor coil or other inductive load, an appropriate rated AC
snubber circuit is recommended (Chromalox Part No. 0149-01305).
Connect before power is applied—Make all electrical wiring connections to the back of the controller before power is applied to the unit.
!
Comply with regulations—WARNING: All wiring practices must
comply with local regulations. Failure to do so could result in damage
to controller and/or personal injury or death from electrical shock.
This instrument is intended for panel mounting and the terminals must
be enclosed within a panel. Use National Electric Code (NEC) Class 1
wiring for all terminals except the sensor terminals.
Check wiring decal—Check the wiring decal on the side of the unit to
verify the model number. The wiring decal shows the wiring terminations. All wiring will be connected to the terminals on the back of the
instrument case. Specific wiring instructions for different input and
output types are given in this section. See also Figure 3.5.
Additional information—For sensor wiring practices, see “Sensor
Input Wiring”. For additional information on good wiring practice,
request IEEE Standard No. 518-1982 from IEEE, 345 East 47th St., New
York, NY 10017 or www.ieee.org.

Sensor Wiring Notes
For safety and best controller performance,
• Sensor leads (thermocouple and RTD) should not be run in the same
conduit as power wiring.
• Twisted pair, shielded wire is recommended for sensor connections.
• False temperature readings can occur if the sensor wire is exposed
to electrical noise.
• Ungrounded thermocouples are recommended.
• Thermocouple extension wire, if required, must be the same type
as the thermocouple (i.e. if a Type K thermocouple is used, then Type
K extension wire must be used.)
• Shielded thermocouple wire, if used, must have the shield
grounded at one end only, preferably at the shield ground terminal on
the controller as shown in Figure 3.6.
• Three-wire RTDs are recommended for greatest accuracy.
• Standard shielded copper wire is recommended for RTD extensions.
Thermocouple Inputs
It is important to observe polarity (+,-) when connecting thermocouple
leadwires. ANSI color coding for the thermocouples used with this
instrument are

Three-Wire RTD Inputs
IMPORTANT: When making the three-wire RTD input connection,
make the resistance of all three extension leadwires equal by using the
same gauge and same length of wire for optimum accuracy. A three-wire
RTD will generally have two wires of the same color. Connect the same
colored wires to the RTDL connections. Connect the alternate colored
wire to the RTDH connection.
Make three-wire RTD connections to terminals as shown in Figure 3.7.

Three-Wire RTD Connections with Shield
Two-Wire RTD Inputs
If using a two-wire RTD input, use heavier gauge leadwires to reduce
leadwire resistance. Any leadwire resistance adds directly to sensor
resistance, thus adding error to the process temperature measurement. It
is also necessary to jumper the two RTDL terminals on the instrument to
complete a two-wire hookup.

Section 5—Control and Alarm Operation
Control Operation
The 2110 is shipped from the factory with PI (proportional/integral)
control. Proportional control actually determines the percent of heat
needed to control the process. The factory setting for the Proportional
Band is 25°F and the Automatic Reset (Integral) is set at 0.1 repeats/
minute. These settings will control many processes without any changes
to the controller. If the process is unstable or too sluggish, the Proportional
Band and Automatic Reset can be changed in the menu configuration.
Tuning PI Control
Adjust Proportional Band The objective of the proportional band adjustment is to find the proportional band setting at which the process temperature stabilizes and does not oscillate. If the temperature display is oscillating, increase the Proportional Band (doubling the value) until the temperature display has stopped oscillating. To establish a quick response to control
upsets, adjust for the smallest band that provides stable control (does not
oscillate). Note: The temperature at this point may not be at set point, but
will be stable.
Adjust Automatic Reset (Integral) The Automatic Reset (Integral)
automatically removes the offset between process temperature and set
point. If the process is too sluggish in approaching set point, double the
automatic reset. Too much automatic reset will make a process unstable.
Cycle Time Cycle time setting determines how often to switch the output
to the heater. For example, if the cycle time is 1 second and the 2110
needs a 75% output, the output will be on for 3/4 of a second and off 1/4
of a second. Units with relay control outputs (R1 or R3) are shipped with
a 30-second cycle time. Units with solid state relays or solid state relay
drives (S0, S1, S2, or V0) are shipped with a 1-second cycle time.
Alarm Operation
(optional)
Chromalox 2110
An alarm relay output is optional on the 2110. An alarm can help protect
the process when a too high or too low temperature occurs.
High Alarm: This alarm is a high absolute alarm that actuates when the
process temperature is equal to or greater than the alarm set point. For
example, if the high alarm set point is 500°F, the alarm will always actuate
when the process temperature reaches 500°F.
Low Alarm: The low absolute alarm actuates when the process temperature
is equal to or less than the alarm set point. The low alarm features a powerup inhibit to prevent undesirable alarms during process start up. After the
unit reaches control set point, the low alarm will respond.
Alarm Dead Band: The alarm relay de-energizes (resets) when the temperature crosses out of the alarm dead band. For example, if the high alarm
is set to 500°F and the alarm dead band is 5°F, the alarm condition will not
reset until the process temperature reaches 495°F.
To enable the alarm relay, select either high or low alarm type and set the
alarm set point. An alarm condition is indicated when the Alarm light to
the left of the display illuminates. Alarm type, set point, and dead band are
selectable through the user configuration interface.

Section 6—Replacing Output Modules
The Chromalox 2110 Temperature Controller was shipped with the
output modules installed as ordered. The 10A Solid State Relay and 20A
Mechanical Relay output cards control small cartridge heater or strip
heater loads directly, eliminating the need for a remote contactor or solid
state relay. If a larger load is required, the 2110 can be configured with a
1A Pilot Duty Relay or Solid State Relay Drive.
The 2110 may be optionally configured with a 5A/120V Alarm Relay.
Alternate modules, configured with or without alarm, can be installed as
needs change.
Control and alarm outputs can be changed in the field.

3. Remove the back cover by lifting four housing clips on the controller.
This releases the back cover. Then pull cover straight off the controller.
4. Gently pry around the sides to loosen and remove the module. Pull
module straight out to avoid bending pin connections.
WARNING: Do not remove module by the handling components
on the module board. This could damage the module.
When removing an S2 output module (SSR with fan), a cable connects the fan to the far right center of the S2 board. Gently disconnect
the cable from the connector on the output board. Do not remove
the fan from the back cover. This is a single assembly.
For the S2 output module, reconnect the fan cable to the connector on
the far right center of the module. Tuck the cable around the heatsink.
Replacement
1. Line up pins on the controller with pin connections on either side of
the module and push the new module into place.
2. Reinstall the back cover.

Auto Cycle Time
The Control Output Modules have a default cycle time of 1 second (fast
switching) or 30 seconds (slow switching) (See table on page 17). After
replacing a control output, the 2110 verifies at power up if a slow or fast
cycle time output has been installed. If an output with a different default
cycle time is installed, the 2110 will change the cycle time to the new
device’s default. If the user has changed the cycle time in configuration,
the 2110 retains this value unless an output with a different default cycle
time has been installed.

Section 7—Calibration
Calibration Offset
Calibration offset offsets the displayed value. Usually, this option is
used to match displays of two different instruments that are measuring
the same temperature, but are displaying different temperatures due to
different thermocouple accuracy or placement of the thermocouples.
Caution is advised when adding an offset to the display, since the actual
sensed temperature will not be displayed.
Calibration offset (coFF) is available in the configuration mode, but
only displays if the security lock (LocH) is set to 736.
Factory Default
Recovery
This option allow you to return the controller’s configuration parameters
back to the factory default values (except for the LocH menu). This
parameter could be used when moving a unit from one application to
another to give the operator an easy place to begin setup of the unit.
Factory Default Recovery is performed in the Configuration Mode,
menu dFLt. The security lock (LocH) must be set to 736 to perform a
factory default recovery.
To reestablish the factory default values:
1. Disconnect load power.
2. In the Configuration Mode, set security level (LocH) to 736.
3. Go to menu dFLt and press . The controller will automatically
reset the values. When the display cycles from rEdy to donE, the
recovery is complete.
Calibration
The Chromalox 2110 Temperature Controller is factory calibrated
before shipment. Recalibration is not needed when you receive and
install the product. Periodic calibration checks or adjustments should not
be necessary under normal operating conditions. Chromalox recommends you recalibrate the controller if all instruments in your facility are
periodically calibrated to a known standard.
The 2110 always retains the original factory calibration values for the J,
K, and RTD inputs. In an application, only one of these sensor inputs
will be used. The 2110 only can retain manual calibration for a single
sensor.

Calibration Notes:
When calibrating the 2110
1. You must have a sensor simulator to calibrate the 2110 controller.
Substitute a precision sensor simulator (Thermocouple simulator or
resistance simulator box) for sensor inputs.
2. Disconnect load power to prevent damage to the process or load.
3. Calibrate RTD inputs using copper (Cu) wire. Calibrate thermocouple inputs using thermocouple extension wire of the same type as
the thermocouple you are calibrating.
4. Allow the controller to warm up with the appropriate sensor simulator connected for at least one hour prior to calibration.
5. To access the calibration menu, you need level C (736) security.
Sensor Calibration:
1. Set the 2110 selection switch to RTD or TC. If TC is selected, then
set the selection switch to J or K.
2. Connect the sensor simulator to the sensor input terminals.
3. Set the simulator to the low value of the sensor selected J TC
(-100°F), K TC (-100°F), RTD (-200°F or 48.46Ω).
4. Go to the CALS parameter on the 2110. The display will toggle
between CALS and inLo.
5. Wait 30 seconds for the electronics to fully stabilize. Press . Dashes
will appear in the display while the controller calibrates the low end
of span.
6. When the controller prompts inHi in the display, adjust the sensor
simulator to the high end of the selected sensor span.
J TC (1400°F), K TC (2400°F), RTD (1000°F or 293.49Ω).
7. Wait 30 seconds for the electronics to fully stabilize. Press . Dashes
will appear in the display while the controller calibrates the high end
of span. When finished, the controller will display donE.
8. Calibration is complete.
Factory Calibration
Recovery
Chromalox 2110
This procedure allows you to return the controller to its factory calibration settings in the event it is severely out of calibration due to poor
technique or unauthorized calibration.
1. Disconnect load power.
2. Cycle the sensor selection switch twice from its original position (TC
or RTD) to the opposite position (RTD or TC) and back to its original
position. This brings back the factory calibration and deletes the
manual calibration settings.
