STARTER TYPES CHAPTER 2: INSTALLATION
2.3.2 Full-voltage reversing starter
Figure 26: Full-voltage reversing starter wiring
The full-voltage reversing starter type is a full voltage or across-the-line reversing starter.
When a start A (forward) control is received, the pre-contactor relay (if any) is picked up for
the set pre-contactor time. When the pre-contactor timer times out, relay1 picks up and
seals-in, picking up contactor F, which starts the motor in the forward direction. When a
start B (reverse) control is received, relay1drops out, and contactor F drops out. When the
contactor F Off status is received, the starter waits for the set transfer time to allow the
motor to slow or stop. When the transfer time timer times out, relay2 picks up and seals-in,
picking up contactor R, which starts the motor in the reverse direction. When a stop
control is received, relays 1 and 2 drop out, contactor F and R drop out, and the motor
stops. The starter logic is fully symmetrical between forward and reverse.
When a contact input has its function set to forward limit, and that contact closes, relay1
will drop out, stopping any forward rotation. When a contact input has its function set to
reverse limit, and that contact closes, relay2 will drop out, stopping any reverse rotation.
The pre-contactor is omitted on forced starts (for example, UVR Immediate, External Start).
Forced starts are not supervised by this starter transfer timer – any external starting circuit
must itself respect fast direction change restrictions.
NOTE
NOTE:
Connect AUX VT to the Control Supply for correct operation of the UV Restart feature and
readings of inputs.
