8. PARAMETER DESCRIPTION
IMR02C15-E4
8-39
Proportional cycle time [cool-side]
Factory default setting:
The screen is displayed.
This is a Proportional cycle time of cool-side in the Heat/Cool PID control.
Proportional cycle time [cool-side] is to set control cycle time for time based
control output such as voltage pulse for SSR, triac, relay and open-collector
output.
Data range Factory set value
Relay contact output (M):
20
0 to 100 seconds
When 0 seconds is set to the Proportional cycle
time [cool-side] in the Parameter setting mode,
the control cycle time for outputs is the value set
at the Time setting of proportional cycle time
[cool-side] (tU) at F51 (P.8-129) in the
Engineering mode.
Voltage pulse output (V),
Triac output (T),
Open collector output:
2
This parameter is displayed when in Heat/Cool PID control.
Proportional cycle time [cool-side] displays when relay contact output,
voltage pulse output, triac output or open collector output is specified to
control output 2 (OUT2).
Proportional cycle time [cool-side] is not displayed when the block
selection at F08 [S.F08] (P. 8-83) is set to “1: No display” in the
Engineering mode.
