Pump Open Alarm; Over Current Alarm; Pump Over Temperature Alarm - SAES NEG Power mini User Manual

This notification indicates that the interlock signal is open.
As we said before INTERLOCK (close contact) is an enable signal, so it is necessary to close short
interlock pins to provide power to the pump. You can provide the close contact with an external circuit
or with the pre-cabled DB9 connector provided with the unit.
