Current Input

1. Install the supplied 249 ohm resistor between terminal #4 and #6.
2. Access the Initial Setup mode by pressing and holding the

;

button for three seconds. In the parameter

inpt

, use the

and

buttons to select the value that corresponds to the current input that will be

applied to the controller. See the table for current specifications. Press the

;

button to save the selected

value. The controller will display the module information splash screen for three seconds and then return to the

main screen.
3. Press the

;

button for three seconds again. Press the

button repeatedly until the parameter

tp-h

appears. Use the

and

buttons to select the high engineering value that corresponds to the maximum

current signal that will be applied to the input of the controller. For example, if the

ma4

4-20mA input is to be

used, this is the value the controller will display when the input equals 20mA. Press the

;

button to save the

selected value. Press the

button to access the parameter

tp-l

. Use the

and

buttons to select

the low engineering value that corresponds to the minimum current signal that will be applied to the input of the

controller. For example, if the

ma4

4-20mA input is to be used, this is the value the controller will display when

the input equals 4mA. Press the

;

button twice to save the selected value and return to the controller main

screen.
4. Press the

button repeatedly until the parameter

appears. Use the

and

buttons to select

to indicate the position of the decimal point for the PV and SV values on the controller. Press the

;

button twice to save the selected value and return to the controller main screen.

5. If the current input PV value displayed on the controller needs to be adjusted, press the

;

button for less

than 3 seconds. Press the

. Verify that the default value

run

is selected. Press

the

;

button to return to the controller main screen.

3. Refer to Section 12-1 of this Quick Start Guide to set up the PID control parameters.

;

button for less than three seconds. Press the

button repeatedly until the parameter

htpd

appears. Use

the

and

5. Optional regulation parameters can be programmed for a second

control output. If this is desired, access the regulation mode again by

pressing the

;

button for less than three seconds. Press the

button until the parameter

Coef

appears. This value allows the cooling

control to have a different proportional setting than the heating loop. The

heating loop proportional band setting is multiplied by the

Coef

value to

create a proportional band setting for the cooling loop control. Use the

and

buttons to change this value if desired. Press the

;

button to save the selected value. Press the

button to access the

parameter

dead

. Use the

and

buttons to enter a deadband

zone value around the setpoint where the output is not effected by the

proportional control value. As long as the PV remains within the deadband

zone the output is not affected by the proportional control. The integral and

derivative controls ignore the deadband setting and may cause the output

to be on within the deadband zone. Press the

;

button twice to save

the value and return to the controller main screen.
