Value range: [0]...999 seconds
Is the temperature increase after the expiration of the
testing period not 5K
,
although the controller outputs
the maximum degree of operation
,
a short circuit alarm
was detected.
The zone is deactivated (degree of operation 0%). In
the actual value display tCSC is shown. The zone can
be activated by the acknowledgement of the alarm.
[P024]APPL - Application
Without function.

Control parameter
This parameter group consists of the control parame--
ters and the parameters that affect the automatic con--
trol parameter calculation.
[P025]H.Pb - Proportional Band of
Heating
Value range: 0.0...25.5% [6.5]
[P026]H.td - Derivative Time of
Heating
Value range: 0...2000 seconds [50]
[P027]H.ti - Integral Time of
Heating
Value range: 0...2000 seconds [50]
[P028]H.Ct - Sampling Time of
Heating
Value range: 0.2...90.0 seconds [0.2]
[P029]C.Pb - Proportional Band of
Cooling
Value range: 0.0...25.5% [6.5]
[P030]C.td - Derivative Time of
Cooling
Value range: 0...2000 seconds [50]
[P031]C.ti - Integral Time of
Cooling
Value range: 0...2000 seconds [50]
[P032]C.Ct - Sampling Time of
Cooling
Value range: 0.2...90.0 seconds [1.0]
[P033]IdE.H - Identification Heating
on
Is an invalid measured value (due to sensor
break) detected during control mode
,
the con--
troller switches automatically over to manual
mode. The last averaged degree of operation
determined by the controller is used as the
new degree of operation.
[oFF]
Function deactivated
on
The function supervises the status and the wi-r-
ing of the sensor of short circuit.
The function is calculated by means of the ac-
tual value
,
the degree of operation and a

(page 30) dependent time. This assures the
detection of already existing as well as sud-
denly arising short circuits.
A short circuit alarm of a sensor is displayed
,
if
Ú
after a sampling time dependent time no
temperature rising is detected although the
controller outputs the maximum degree of
operation.
Ú
a sudden drop of temperature is detected.
After detection of a short circuit of the sensor
tCSC is shown in the actual value display and
the zone is deactivated. The zone can be ac-ti-
vated by the acknowledgement of the alarms

Function deactivated
No parameter calculation for control parame--
ters of heating is done during the heating up
phase. The heating is done due to the adju-st-
ed set point.
