P1078 – Value for High Level Alarm of the Process Variable of the External PID
Controller
Adjustable -32768 to 32767
Range:
Properties:
Access groups HVAC
via HMI:
Description:
This parameter defines the value above which the process variable of the external PID controller will be
considered high level according to its engineering unit.
NOTE!
This parameter will be viewed according to the selection of the parameters for the engineering unit
2 (P0512 and P0513).
P1079 – Time for High Level Alarm of the Process Variable of the External PID
Controller
Adjustable 0.00 to 650.00 s
Range:
Properties:
Access groups HVAC
via HMI:
Description:
This parameter defines the time with the high level condition of the process variable of the external PID controller,
so that the alarm message "A0788: High level alarm of the process variable of the external PID controller" will
be generated. With P1075 programmed for 2, the fault "F0789: High level fault of the process variable of the
external controller" will be generated after the motor driven by the CFW501 frequency inverter is decelerated
and is no longer spinning.
NOTE!
Value in 0.00 s disables the alarm detection.
