Pump Control Quick Guide
25
Condition for frequencies where auxiliary pumps are connected/disconnected
Condition for the connection of the additional pump
Using this control topology, it can be necessary to delay the disconnection of the motor from the
commercial power supply (J37), in order to prevent the simultaneous disconnection of the auxiliary and
the additional pumps. That is, the first pump to be disconnected should be the additional pump and then
the auxiliary pump, but never at the same time.
The following table (Table 3.2) shows the specific function codes to successfully control a mono-regulated
pump control system with 1 regulated pump + 4 auxiliary pumps + 1 additional pump:
Table 3.2: Specific function codes for Mono-regulated pump control with 1 regulated pump + 4 auxiliary
pumps + 1 additional pump
Note:
The default setting for function code J93 and J94 (0 Hz) may work properly in your installation
without adjusting it to the suggested value (40 Hz and 39 Hz respectively).
