CHAPTER 2: INSTALLATION STARTER TYPES

Figure 2-29: Full-voltage non-reversing starter control wiring - IO_E
NOTE:
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).
NOTE:
Connect AUX VT to the Control Supply for correct operation of the UV Restart feature and
correct input readings.
