Check FFH Setpoint Circuit

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

Trigger On Alt Setpoint FET is ON and FFET Feedback Voltage is below Minimum ON Threshold OR ALT Setpoint FET is OFF and FET Feedback Voltage is above Maximum OFF Threshold. Trigger Off If alarm was active when ALT Setpoint 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 Setpoint 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
