Check FFH Enable Circuit

The FFH Enable circuit feedback is out of range; the unit gives an alarm only.

Trigger On Alt Enable FET is ON and FFET Feedback Voltage is below Minimum ON Threshold OR ALT Enable FET is OFF and FET Feedback Voltage is above Maximum OFF Threshold. Trigger Off If alarm was active when ALT Enable Output was ON, trigger OFF if Output is ON and FET Feedback Voltage is sensed in Active range OR If alarm was active when ALT Enable Output was OFF, trigger OFF if Output is OFF and FET Feedback Voltage is sensed in Inactive range OR Alarm Reset OR Cycle Power

Alarm only
