detailed description of each starter type.
CHANGE OVER CURRENT
1.5 xFLC
Range: 1.0 to 5.0 x FLC or OFF; Step: 0.1 x FLC
Appears only when STARTER TYPE is WYE DELTA OPN TRNS or WYE DELTA
CLS TRANS. Before CHANGE OVER CURRENT comes into effect on a wye
delta start, a minimum of 25% of the CHANGE OVER TIME must have
expired. After 25% of the time has expired and the average of the three
phase currents has dropped below the CHANGE OVER CURRENT value, the
transition from wye (Contactor A) to delta (Contactor B) will occur. If this
setpoint is OFF, 100% of the CHANGE OVER TIME must expire for the wye to
delta transition to occur.
CHANGE OVER TIME:
30 s
RANGE: 1 to 100 seconds; Step: 1 second
Appears only if STARTER TYPE is set as WYE DELTA OPN TRNS or WYE DELTA
CLS TRANS. See CHANGE OVER CURRENT setpoint above for operation.
TRANSFER TIME:
10 s
Range: 1 to 125 seconds; Step: 1 second
Appears only if STARTER TYPE is set as FV REVERSING or TWO SPEED. With
two-speed starters, this delay is required when the motor is switched
from high speed (Contactor B) to low speed (Contactor A). The delay
starts when Contactor B drops out. With a reversing starter, this delay
occurs when switching from forward (Contactor A) to reverse (Contactor
B) and from reverse to forward.
HIGH SPEED START
BLOCK: DISABLE
Range: ENABLE, DISABLE
Appears only if STARTER TYPE is TWO SPEED. When disabled, the MM2
allows the motor to be started directly to high speed. When enabled, the
motor must be started in low speed before switching to high speed.
RAMP UP TIME:
5 s
Range: 1 to 125 seconds; Step: 1 second
Appears only if STARTER TYPE is selected as INVERTER. See the descrip-
tion of the Inverter starter type for details on functionality.
RAMP DOWN TIME:
5 s
Range: 1 to 125 seconds; Step: 1 second
Appears only if STARTER TYPE is selected as INVERTER. See the descrip-
tion of the Inverter starter type for details on functionality.
STAGE ONE SHORTING
TIME: 5 s
Range: 1 to 125 seconds; Step: 1 second
Appears only if STARTER TYPE is SLIP RING or PART WINDING. This is the
time delay from the closure of Contactor A to the closure of Contactor B.
