Fault 2: Input to Primary Motor Not Received
The controller did not receive a signal from the starter when the pump was turned on.
 If the soft starter fault light is on, look for loose wires.
 Make sure the contactor on the starter is operating correctly.
Fault 2: Primary Motor
The primary motor did not start.
HyPrecision P-15/P-30/P-50 – The thermal overload relay has tripped.
An overcurrent condition causes the thermal overload relay to become hot. When it becomes too hot, the
relay trips. The relay must cool before it can be started again.
Push the blue button to reset the relay.

The relay can take some time to cool before resetting.
