5.9.6 Enable / Disable Communication Writing 

[PAR4→ COMW]

This function can change the parameter settings stored in the memory with the PC, GP, PLC, etc. to enable or 

disable writing. Default setting: EnA.

Setting

Description

EnA

Enable parameter set / modification via communication.

DIsA

Prohibit the setting or modification of parameters by communication.

Note: Parameter settings can be read even if writing them is disabled.

5.10 OTHER FUNCTIONS

5.10.1 Heating MV Monitoring 

Displays the current heating 

MV 

during  heating  control  or  heating  and  cooling  control.  The 

MV 

can be set 

manually to control the temperature.

 

Measuring range: 

H 0.0…H 100 

(unit: %)

 

Note: The MV can be displayed with a moving decimal point (H99.9 → H100).

5.10.2 Cooling MV Monitoring

Displays the current cooling 

MV 

during  cooling  control  or  heating  and  cooling  control.  The 

MV 

can be set  

manually for temperature control.

 

Measuring range: 

C 0.0…C 100

 

(unit: %)

 

Note: The MV can be displayed with a moving decimal point (C99.9 → C100).

5.10.3 Heating Current Monitoring 

[PAR1 → CT-A]

This function monitors and displays the current of the controlled heater 

(load)

. Unit: A.

Note: A current transformer (CT) is used to measure and display the heating (load) current. The availability of the heating 

current  monitoring  function  varies  by  model  and  controller  output  type.  For  the  heater-cooler  model,  the  heater  flow 

monitor function can be used on OUT1. 

5.10.4 RUN/STOP 

[PAR1 → R-S]

In ‘Normal’ mode 

(RUN)

, users can manually start or stop control output. Default setting: RUN.

The stop command stops the control output. However, the auxiliary output is not affected by this command. 

 

This function can be enabled by configuring the parameters. In addition, the digital input buttons on the front 

panel 

(for 

 3 seconds)

 and the digital input terminals 

(DI-1)

 can be assigned to the 

[STOP]

 function.

Setting

Description

RUN

Forced control output start in STOP mode.

STOP

Forced control output stop in ‘Normal’ mode.

Note: When the stop function is enabled, the front panel SV display will show STOP. The setting can be changed when  

the controller stopped. The stop status remains in effect even after the controller is stopped and turned on again. When 

the STOP mode is active, STOP MV [StMV] is present at the output. If a sensor is interrupted in STOP mode, the STOP 

MV [StMV] is displayed. The run / stop setting remains in effect even after the power is turned back on. If the digital input 

(DI-1) function is set to RUN / STOP [STOP], the RUN / STOP function is not possible to change by the front buttons or 

parameters.

5.10.4.1 Stop Control Output Settings 

[PAR5 → StMV]

This parameter sets the output value of the controller when stopped. Use the ON / OFF control to select between 

100 

(ON)

 and 0.0 

(OFF)

. With PID control, the user can set the 

MV 

value between 0.0 and 100. 

Default setting: 0.0%.
