Control Of Additional Cooling Stage - Extended Settings; Additional Cooling Stage; Additional Cooling Stage - Mode Of The Control Value; Additional Stage Cooling - Pwm Cycle Cooling (Min) - Busch-Jaeger SD/U12.55.11-825 Manual

8.18.53 Control of additional cooling stage — Extended settings
Options:
This parameter enables additional functions and communication objects, e.g. "Additional cooling
stage".

8.18.54 Additional cooling stage

Note
Only available when the "Extended settings" parameter under "Control of
additional cooling stage" is set on "Yes".
8.18.55 Additional cooling stage — Mode of the control value
Options:
The mode of the control value can be used to adapt the control value to de-energised opened
(normal) or de-energised closed (inverse) valves.
– Normal: Value 0 means "Valve closed".
– Inverse: Value 0 means "Valve open".
8.18.56 Additional stage cooling — PWM cycle cooling (min)
Options:
In PI PWM, On/off the control value percentage values are converted into a pulse-interval
signal. This means that a selected PWM cycle will be divided into an on-phase and an off-phase
based on the control value. Accordingly, a control value output of 33% in a PWM cycle of 15
min. results in an On-phase of five minutes and an Off-phase of 10 min. The time for a PWM
cycle can be specified here.
Notice
This parameter is only available when the "Control value type" parameter is set
on "PI PWM, Off/On".
