Step 10 – Operate the Inverter
The PACESETTER
TM
“NEMA 4” series inverter is operated using the switches
and speed dial on the front panel of the control. See Figure 10 for panel layout.
1) Turn the AC power ON using the toggle switch. The power lamp will
illuminate.
2) Turn the direction switch to either the “forward” or “reverse” position.
3) Adjust speed by turning the knob of the speed potentiometer. Turning the
pot fully CCW will produce the minimum output frequency, as set by the MIN
trim pot inside the control (factory setting is 0 Hz). Turning the pot fully CW
will produce the maximum output frequency, as set by the max speed
jumper and the MAX trim pot inside the control (factory setting is 60 Hz).
4) To stop the motor momentarily, turn the direction switch to the “stop”
position.
5) To change direction of the motor, turn the direction switch to the “stop”
position, wait until the motor comes to a complete stop, and then turn the
direction switch to either “forward” or “reverse” position.
6) To stop the motor for long periods of time, turn the AC power off using the
toggle switch.
7) If the motor does not start promptly and run smoothly, refer to the
“TROUBLESHOOTING” section.
Step 11 – Adjust Trim Pots (Optional)
These controls contain trim pots that have been factory adjusted for most
applications. Some applications may require readjustment of the trim pots in
order to tailor the control to exact requirements.
WARNING
Do not adjust trim pots with main power on if possible. If
adjustments are made with power on, insulated adjustment
tools must be used and safety glasses must be worn. High
voltage exists in this control. Electrocution and/or fire
hazard can result if caution is not exercised.
