Troubleshooting

POWER LED

The green POWER LED is on when AC line voltage is
applied and the control’s low-voltage power supply is
operational.

FAULT LED

The red FAULT LED turns on when the drive output is
locked out or not ENABLED and any one of the following
fault conditions occur:

1. Overvoltage

• VFD 230AC controls: DC bus exceeds 400 VDC
• VFD 115AC controls: DC bus exceeds 200 VDC

2. Undervoltage

• VFD 230AC controls: DC bus drops below 200 VDC
• VFD 115AC controls: DC bus drops below 100 VDC

3. Instantaneous Overcurrent Trip - Inverter output current has

exceeded safe levels.

Note: The FAULT condition must be reset using the

ENABLE function of the VFD (opening and closing
the ENABLE input).

Diagnostic LEDs

Minarik VFD Series drives are equipped with diagnostic
LED’s to assist the user in troubleshooting and monitoring
equipment status while in use. Refer to Figure 29 (page
58) for diagnostic LED locations.
