When Contactor B Status N.O. reads open, open contactor A output relay.
If feedback is not received from the 1M contact to the Contactor A Status N.O. input within
one second of closing Contactor A output relay, an open control circuit alarm will occur.
This will cause Contactor A and B output relays to open.
If Contactor B Status N.O. does not receive feedback from the up to speed contact on the
soft starter within the
RAMP UP TIME
setpoint during a start, a drive failed to start alarm
will be generated. If Contactor B Status N.O. feedback remains at the MM3 Motor Manager
3 after the
RAMP DOWN TIME
has expired during a stop, a drive failed to stop alarm will be
generated.
If feedback remains at Contactor A Status N.O. input more than 1 second after opening the
Contactor A output relay, a welded contactor alarm occurs. If feedback remains at the
Interlock configured for bypass contact more than one second after opening the auxiliary
output relay, a welded contactor alarm occurs. If feedback is not received from the bypass
contact interlock input within one second of closing auxiliary output relay, an open control
circuit alarm occurs. This will cause contactor A and B output relays to open.
