Full-voltage
Reversing
Starter
This starter type is a full voltage or across-the-line reversing starter. When the forward
button is pressed, the F coil is picked up and sealed in by CR1. The TR1 timing relay coil is
also picked up, thus preventing a change in direction until TR1 drops ou
t and closes again. When the R button is pressed, the R coil picks up and is sealed-in by
CR2. The TR2 timing relay is also picked up. The motor will reverse direction, provided TR1
has timed out and closed the circuit.
Figure 2-6: Full-voltage Reversing Starter
To program the MM3 Motor Manager 3 for full-voltage reversing starter, set:

The
TRANSFER TIME
setpoint appears if the “FV REVERSING” starter type has been
selected. This delay occurs when the motor is running in the forward direction (contactor A)
and the MM3 Motor Manager 3 receives a Start B command to run in the reverse direction
(contactor B) and vice versa.
Start sequence:
1.
Start A command received by the MM3 Motor Manager 3 (serial, switch input
or faceplate).
2.
Close and maintain Contactor A output relay – the motor is now across the
line in the forward direction.
Stop/trip sequence:
1.
Stop command received by the MM3 Motor Manager 3 or a trip occurs.
2.
Open the currently closed Contactor output relay – the motor stops.
