2110 Temperature Controller Section 1—Quick Setup After the controller is properly wired into the system, the user only needs to verify the sensor input and control type and adjust the set point. Setting the Sensor and Control Mode Adjust the dip switches located on the bottom of the unit as shown in Figure 1.1. The factory settings are J, TC, °F, and PI. It is simpler to adjust the dip switch prior to mounting the 2110. K TC ˚F PI J RTD ˚C ONOF J RTD ˚C ONOF K TC ˚F PI Figure 1.
Section 2—Introduction Description The Chromalox 2110 Temperature controller offers simple setup, flexibility and control features in an attractive, compact design. The 2110 is housed in a rugged, plastic 1/4 DIN package that only requires four inches behind the mounting surface. Straightforward operation and easy-to-use control features are major strengths of the 2110 controller. Easy Three-Step Setup: The 2110 delivers exceptional process temperature control.
2110 Temperature Controller Typical Application Figure 2.2 shows the 2110 in a typical application. Figure 2.2 Typical Application Model Identification Before installation, please identify your controller model number. The model number appears on a label on the side of the housing. Use Figure 2.3 to identify the options in your controller.
Section 3—Installation and Wiring Sensor and Control Type Selection Switches Set the Chromalox 2110 controller’s configuration via mechanical dip switches, located on the bottom of the unit. Factory settings are J, TC, °F, and PI Control. Switches are easier to set before mounting. To change the switch settings, first disconnect all wiring and power from the unit.
2110 Temperature Controller Mounting Two mounting collars securely hold the 2110 controller in the mounting hole. Remove these mounting collars before installation. Removing Mounting Collars 1. To remove the rear collar, press the sides of the collar. This releases holding tabs on the top and bottom of the collar. 2. Slide the collar off the back of the unit. 3. Slide the front collar off the back of the unit Press In Holding Tabs Front Collar Rear Collar Press In Figure 3.
Mounting continued Mount the 2110 1. Cut out a 1/4 DIN, 3.6-inch (92mm) square hole in the mounting panel. 2. Insert the unit into the mounting hole as shown in Figure 3.4. 3. Slide the front mounting collar onto the back of the controller. 4. Slide the rear mounting collar onto the back of the controller until the holding tabs securely engage with the holding tab slots in the controller housing (see Figure 3.4). 5. Tighten the four rear collar mounting screws until the unit is held firmly in the panel.
2110 Temperature Controller 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.
Sensor Input Wiring 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.
2110 Temperature Controller Sensor Input Wiring continued 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.
Control Output Wiring The following figures show the proper control output wiring for the various 2110 configurations. R1 (1 Amp Relay) and S0 (1 Amp, Solid State Relay) Output Wiring When driving a contactor coil or other inductive load, an appropriately rated AC snubber circuit is recommended (Chromalox Part. No. 0149-01305), as shown in Figure 3.9. 120/240 Fuse VAC COM NO NC Load Neutral Snubber Figure 3.

Section 4—Adjusting Set Point and Configuration Adjusting the Set Point 1. Set selection switches (see Figure 3.1). 2. Apply power to the unit. 3. To adjust the set point on the Chromalox 2110 Temperature Controller, press and hold the Set Point button (see Figure 4.1). The Set Point light is illuminated and the set point value is displayed. 4. While still pressing the Set Point button, press either the or button to adjust the set point to the desired value (see Figure 4.2). 5.
2110 Temperature Controller Configuration continued 4. Press the or buttons to adjust the value (only the value is displayed during adjustment). See Figure 4.7. The new value is set when the or button is released. 5. Press and hold the Set Point ( ) button and press the button to advance to the next menu. See Figure 4.8. (Holding the Set Pointt ( ) button and pressing the button moves through menus in the opposite direction.) Repeat steps 4 and 5 through the configuration menus.
Security Codes and Levels To limit access to the user configuration interface, security codes are assigned to different menu levels. Make security codes available to operators, maintenance crew, supervisors, etc. according to what function level you want for each group. Security Level C is not recommended for most users. Gain access to configuration menus using the following codes.
2110 Temperature Controller Configuration Menus continued Menu Code Function CYCL Cycle Time db Adjustable Factory Range Default Security Level .1 to 60.0 Sec. Output R1, R3 = 30 sec. S0, S1, S2, V0 = 1 sec.
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.
10 Temperature Controller 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.
Module Installation continued ! 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.
2110 Temperature Controller 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 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.
