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
• FHP 230AC controls: DC bus exceeds 400 VDC
• FHP 115AC controls: DC bus exceeds 200 VDC
2. Undervoltage
• FHP 230AC controls: DC bus drops below 200 VDC
• FHP 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 FHP (opening and closing
the ENABLE input).
Diagnostic LEDs
LEESON FHP 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
