DIGITAL INDUSTRIAL CONTROLLER
english
2-point PWM (2-point PWM signal)
Period
T+: Period of the PWM signal
(refers to relay 1)
Adjustment range:
1 ≤ T+ ≤ 999,9 (in sec.)
Manipulated variable limiting
COh: High manipulated variable limit
Adjustment range:
COl
≤ COh ≤ 100 (in %, with reference to
the time period of the PWM Output T+)
COl: Low manipulated variable limit
Adjustment range:
0
≤ COl ≤ COh (in %, with reference to
the time period of the PWM Output T+)
The upper manipulated value limit determines the maximum switch-on time, and the
lower regulated value limit the minimum switch-on time of the Output Relay 1. The
entry of the switch-on time is made as a percentage of the time period.
Line of action
inv: no The output operates with a positive line of action
inv: yes The output operates with a negative line of action
Pulse output
This function allows you to trigger a pulse valve.
(Relay 1 controls the pickup winding, while relay 2 controls the dropout winding)
Imp: no Pulse valve is not used
Imp: yes Pulse valve is used
3-point PWM (3-point PWM signal)
Period
T+: Period of the PWM signal for „Heating“ (Relay 1)
Adjustment range:
1 ≤ T+ ≤ 999.9 (in sec.)
T-: Period of the PWM signal for „Cooling“ (Relay 1)
Adjustment range:
1
≤ T- ≤ 999.9 (in sec.)
