Impulse PCW-5181 user manual Connecting AC Power, LED Diagnostic Indications

Chapter 3 - Connecting and Installing Your Impulse

D. Connecting AC Power

There is no ON/OFF switch on the Impulse. AC power is applied by plugging the *power cord (included) into the connector on top of the Impulse.

Input voltage must be in the range of 120 VAC ± 10%, single phase, 50/60 Hz, 500 VA max @ 4 Amps. Operation outside these specifications will result in reduced performance, drive faults, and may damage the drive.

When power is applied, the LED on front of the drive should briefly turn red, then steady green. If a red light is present, see Section E of this chapter for more information on fault detection codes.

*Note: If the AC power cord requires replacement, the replacement must be rated for Hard Usage or Extra Hard Usage.

E. LED Diagnostic Indications

To AC

Power

Supply

The Impulse drive detects and resolves fault conditions (see table below). Faults are signaled by either a steady red or a flashing red LED on the front panel. A solid green LED indicates normal operation. A slowly flashing green LED indicates a shutdown (disabled), while a rapidly flashing green LED signals a regen dump. Faults are cleared by either 1) cycling power, 2) sending a RESET command via the serial port or configurable logic input, or 3) probing the motor if the LED is steady red.

For more detailed explanation of faults refer to Chapter 7, Troubleshooting the Impulse.
