The above drawing applies only to a high-voltage power supply. If a low-voltage (DC)
power supply is used, an appropriate DC voltage source must be used for this power
supply.
.
The full-voltage non-reversing starter type is a full voltage or across-the-line non-reversing
starter.
When a start 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 M, which starts the motor. When a stop control is received, relay1
drops out, contactor M drops out, and the motor stops. The pre-contactor is omitted on
forced starts (for example, UVR Immediate, External Start).
Connect AUX VT to the Control Supply for correct operation of the UV Restart feature and
correct input readings.
