1. Quick Setup

After the controller is properly wired into the system,

the user only needs to verify the sensor input and con-

trol 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.

2. To adjust the set point on the Chromalox 2110 Tem-

perature Controller, press and hold the Set Point

button (see Figure 1.2). The Set Point light is illumi-

nated.

3. While still pressing the Set Point button, press either

the

button to adjust the set point to the de-

sired value (see Figure 1.3). Holding the

2. Introduction

Description

The Chromalox 2110 Temperature controller offers

simple setup, ﬂexibility and control features in an at-

tractive, compact design. The 2110 is housed in a rug-

ged, 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. Your process is up and

running after three easy setup steps: 1) Select the sen-

sor and control type, 2) Hook up the system and 3)

Select the desired temperature.

Inspection & Unpacking

Your Chromalox 2110 controller should arrive in good

condition. Upon arrival, inspect the packaging for any

visible damage.

Unpack the controller and carefully inspect for product

damage that may have occurred during shipment. If the

package or contents have been damaged in shipping,

you must ﬁle a claim with the delivery service. The de-

livery service will not accept a claim from the shipper.

If not immediately installing the controller, store in a

cool, dry environment in its original protective packag-

ing. Temperature extremes and excessive moisture can

damage the instrument.

Typical Application

Figure 2.2 shows the 2110 in a typical application.

Model Identiﬁcation

Before installation, please identify your controller mod-

el number. The model number appears on a label on

the side of the housing.

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 wir-

ing and power from the unit. Adjust switch settings as

follows:

If input type is thermocouple, switch A selects either

thermocouple type Jor K.

Switch B selects input type thermocouple or RTD

(resistance temperature detector). Note: If RTD is se-

lected, switch A is ignored.

Switch C selects temperature units °F or °C.

Switch D selects either PI (Proportional-Integral) or

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 col-

lar. This releases holding tabs on the top and bot-

tom of the collar.

2. Slide the collar off the back of the unit.

3. Slide the front collar off the back of the unit.

3. Installation and Wiring

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. CAUTION: Do

not overtighten.

The controller will now be held ﬁrmly in place.

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 sepa-

rate 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 induc-

tive 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.

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 Nation-

al 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 Input Wiring

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 sen-

sor 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 ac-

curacy.

• Standard shielded copper wire is recommended for

RTD extensions.

Thermocouple Inputs

ing 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 opti-

mum 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 lead-

wires to reduce leadwire resistance. Any leadwire re-

sistance adds directly to sensor resistance, thus add-

ing 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.

Control Output Wiring

The following ﬁgures show the proper control output

wiring for the various 2110 conﬁgurations.

Output Wiring

When driving a contactor coil or other inductive load,

an appropriately rated AC snubber circuit is recom-

Conﬁguration

While the 2110 default settings make it a simple setup

controller for most applications, additional program-

mable menus can be conﬁgured through three front-

panel pushbuttons.

To access the user conﬁguration menus:

1. Press and hold the

buttons. After three

seconds the display will begin to toggle between

the current security code and LocH (LOCK). The

Temp and Set Point LEDs will turn on. See Figure

4.3.

2. Press the

button to adjust the value to the

appropriate security number (see Security Codes

and Levels). Only the value is displayed during ad-

justment. See Figure 4.4.

3. Press and hold the Set Point ( ) button and

press the

buttons to scroll the conﬁguration

menus. The display will show the name of the menu

and then begin to toggle between the name and the

current value. See Figures 4.5 and 4.6.

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 re-

leased.

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 Point ( ) button and

pressing the button moves through menus in the

opposite direction.)
