P3.13.9.3 SUPERVISION UNIT SELECTION (ID 1687)
Use this parameter to select the unit for the input pressure signal.
You can scale the supervision signal (P3.13.9.2) to process units on the panel.
P3.13.9.4 SUPERVISION UNIT DECIMALS (ID 1688)
Use this parameter to set the number of decimals for the input pressure signal unit.
You can scale the supervision signal (P3.13.9.2) to process units on the panel.
P3.13.9.5 SUPERVISION UNIT MINIMUM VALUE (ID 1689)
Use this parameter to set the minimum value of the input pressure signal.
Enter the value in the selected process unit. For example, an analogue signal of 4...20 mA
corresponds to the pressure of 0...10 bar.
P3.13.9.6 SUPERVISION UNIT MAXIMUM VALUE (ID 1690)
Use this parameter to set the maximum value of the input pressure signal.
Enter the value in the selected process unit. For example, an analogue signal of 4...20 mA
corresponds to the pressure of 0...10 bar.
P3.13.9.7 SUPERVISION ALARM LEVEL (ID 1691)
Use this parameter to set the limit for the input pressure alarm.
If the measured input pressure goes below this limit, an input pressure alarm occurs.
P3.13.9.8 SUPERVISION FAULT LEVEL (ID 1692)
Use this parameter to set the limit for the input pressure fault.
If the measured input pressure stays below this level for longer than the set time, an input
pressure fault occurs.
P3.13.9.9 SUPERVISION FAULT DELAY (ID 1693)
Use this parameter to set the maximum duration for the input pressure to stay below the
fault limit before an input pressure fault occurs.
P3.13.9.10 PID SETPOINT REDUCTION (ID 1694)
Use this parameter to set the rate of the reduction of the PID setpoint value when the
measured input pressure is below the alarm limit.
10.14.10 FROST PROTECTION
Use the Frost protection function to protect the pump from frost damages. If the pump is in
sleep mode and the temperature that is measured in the pump goes below the set protection
temperature, operate the pump at a constant frequency (that is set in P3.13.10.6 Frost
Protection Frequency). To use the function, you must install a temperature transducer or a
temperature sensor on the pump covering or on the pipe line near the pump.
P3.13.10.1 FROST PROTECTION (ID 1704)
Use this parameter to enable the Frost Protection function.
