P1032 – Time for Low Level Alarm of the Process Variable of the Main PID Controller
Adjustable
Range:
0.00 to 650.00 s Factory
Setting:
5.00 s
Properties:
Access groups
via HMI:
HVAC
Description:
This parameter defines the time with the low level condition of the process variable of the main PID controller,
so that the alarm message “A0760: Low level alarm of the process variable of the main PID controller“ will be
generated. With P1030 programmed for 2, the fault “F0761: Low level fault of the process variable of the main
controller” will be generated after the motor driven by the CFW501 frequency inverter is decelerated and is no
longer spinning.
NOTE!
The value set to 0.00 s disables the alarm detection.
P1033 – Value for High Level Alarm of the Process Variable of the Main PID Controller
Adjustable
Range:
-32768 to 32767 Factory
Setting:
900
Properties:
Access groups
via HMI:
HVAC
Description:
This parameter defines the value above which the process variable of the main 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
1 (P0510 and P0511).
