P3.15.18.2 SUPERVISION ALARM LEVEL (ID 1699)
Use this parameter to set the overpressure limit for the Overpressure supervision.
If the PID feedback becomes higher than the set overpressure limit, all auxiliary motors stop
immediately. Only the regulating motor continues to operate.
10.16.6 PUMP RUNTIME COUNTERS
In the Multi-pump system, the time that each pump operates is monitored by a runtime
counter. For example, the order that the pumps start is specified by the runtime counter
values to make the wear of the pumps in the system more equal.
The pump runtime counters also tell the operator to do a maintenance on a pump
(parameters P3.15.19.4 - P3.15.19.5 below).
The Pump runtime counters are in the monitoring menu, see Table 23 Multi-pump monitoring.
P3.15.19.1 SET RUNTIME COUNTER (ID 1673)
Use this parameter to set the value that is specified by 'Set RunTime: Value' parameter to the
runtime counter of the selected pump.
P3.15.19.2 SET RUNTIME COUNTER: VALUE (ID 1087)
Use this parameter to set the value of the runtime counter of the selected pump when 'Set
RunTime Counter' parameter is selected.
