9.2 FV REVERSING STARTER 9.2.1 DESCRIPTION
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 out 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 9–3: FULL VOLTAGE REVERSING STARTER
To program the MM2 for full-voltage reversing starter, set:
S1 CONFIGURATION\STARTER\STARTER TYPE: FV REVERSING
S1 CONFIGURATION\STARTER\TRANSFER TIME: 1 to 125 seconds
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 MM2 receives a Start
B command to run in the reverse direction (Contactor B) and vice versa.
