Multi-pump (M3.14)
The Multi-Pump functionality controls up to four motors (pumps or fans) with PID Controller 1. The drive is
connected to one motor which is the regulating motor. This motor connects and disconnects the other motors
to/from the mains using contactors controlled with relays when needed, to maintain the correct setpoint.
The Auto-Change function controls the order/priority in which the motors are started to guarantee their equal
wear. The controlling motor can be included in the Auto-Change and interlock logic, or it may be selected to
always function as Motor 1. Motors can be taken out of use momentarily (for example, for service). This is
completed using the interlock function.
The Multi-Pump settings are presented in the following table:
