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 47 th 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.

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.

Alarm Operation

(optional)

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.

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 power-up 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.

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.

Replacing Output Module

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:

Section 7–Calibration 19 continued

Calibration

continued

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 48.46

W).

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 293.49

W).

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

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.
