The
CONTACTOR SEQUENCE
appears when the autotransformer closed transition starter
type has been selected. The 1S-2S value means that the 1S contactor will close ahead of
the 2S contactor as per some wiring practices. The 2S-1S value means that the 2S
contactor will close ahead of the 1S contactor as this is another common wiring practice.
The
CHANGE OVER TIME
setpoint appears only if the autotransformer open or closed
transition starter types have been selected. For the autotransformer starter type, this is the
time delay from the closure of contactor A output relay until the opening of contactor A
output relay. The
STARTS PER HOUR
setpoint only if the autotransformer starter type has
been selected. This setpoint limits the number of starts per hour to prevent overheating of
the autotransformer windings.
Start (
CONTACTOR SEQUENCE
set to 1S-2S) sequence:
1.
Start command received by the MM3 Motor Manager 3 (serial, switch input or
faceplate).
2.
Close and maintain Contactor A output relay – close 1S contactor.
3.
Wait 20 ms, close and maintain auxiliary 1 relay; power is applied to the
autotransformer.
