REMEDY
§ Check incoming power supply��
§ Check the control circuit fuse��
§ Check the transformer secondary
windings for the control voltage��
§ Change Star / Delta timer��
Top up coolant��
§ For relay, set overload to correct value��
For current transducers, ensure set point
is correct in controller��
§ Ensure voltage does not drop below
10% on start up and 6% running��
Set pressure to correct rating for
machine��
Change air filter, and separator
cartridge��
§ Ensure voltage does not drop below
10% on start up and 6% running��
Correct incoming supply voltage��
† Change Airend��
Change air filter��
Set pressure to correct rating for
machine��
Reduce site voltage to correct operating
voltage��
