The

is
selected as “INVERTER”. See the next section for details on functionality.
Start sequence:
1.
Start command is received by the MM3 Motor Manager 3. (serial, switch input
or faceplate).
2.
Close and maintain contactor A output relay. - provide power to the inverter
3.
Wait for one second.
4.
Close and maintain contactor B output relay. - signal the inverter to start the
motor.
5.
Wait for the
RAMP UP TIME
for Contactor B Status N.O. to close.
Stop/trip sequence:
1.
Stop command is received or a trip occurs. (serial, switch input or faceplate)
2.
Open contactor B output relay.
3.
Wait for the
RAMP DOWN TIME
for Contactor B Status N.O. to open.
4.
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
1 second of closing Contactor A output relay, an open control circuit alarm occurs. This
causes the 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
inverter 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 one second after opening
the contactor A output relay, a welded contactor alarm will occur.
