Alarm and Control Assembly Controls and Indicators
Item
Function
(+)HVSD
(Test jack) Used with the (-)VOLTS (X10) jack to measure the rectifier shelf high voltage shutdown
DC voltage trip point. A DC voltmeter connected to these jacks indicate 1/10 actual voltage.
(+)BAT ON DISCH
(Test jack) Used with the (-)VOLTS (X10) jack to measure the battery voltage on discharge trip
point. A DC voltmeter connected to these jacks indicate 1/10 actual voltage.
HVSD VOLT ADJ
(Potentiometer) Used to adjust the voltage at which a rectifier module shuts down (if the module
is delivering more than 10% of rated load).
BAT ON DISCH ADJ
(a)
(Potentiometer) Used to adjust the voltage at which a Battery On Discharge alarm occurs.
RESTART/LOCKED OUT
(Red LED) Lighted 4 seconds after a high voltage condition occurs.
RESTART RESET
(Push-button switch) When pressed, resets the internal timer on the HVSD circuit.
(a) The battery disconnect panel pin must not be in the BATTERY DISCONNECT jack during this procedure.
