9.0 ALARM LIGHTS AND SET POINTS
9.1 Alarm Lights
Alarm lights are located on the front of the unit.
AC “On”:
The LED illuminates when AC power is applied to rectifier and AC breaker is in the “ON” position.
Blown DC Protection:
The LED illuminates when DC breaker or DC fuse opens. The blown DC protection indicator (BDCPI) should
be replaced when DC fuse opens on three phase units.
Summary Alarm:
The LED illuminates on low voltage, high voltage, or low DC current. **(Provided LDCA is selected as a
summary alarm condition Factory set “YES”) The summary alarm can also be programmed to include AC
power failure.
Consult factory for changing summary operation.
Float-Equalize Light:
The proper LED will illuminate, indicating which charge mode the rectifier is operating in.
9.2 HIGH VOLTAGE
An LED blinks when rectifier or battery voltage exceeds a predetermined adjustable level. The factory
setting is 2.45 volts/cell (Lead) (VRLA) or 1.6 volts/cell (N.C.).
9.3 HIGH VOLTAGE SHUTDOWN (HVSD)
The HVSD is factory set at 2.5 volts/cell (Lead) (VRLA) or 1.65 volts/cell (N.C.). For the HVSD circuit to
operate, it will be necessary to have a DC load or battery on the rectifier’s output. When the DC voltage
exceeds the setting, the high voltage/HVSD LED will be on solid indicating high voltage shutdown.
CAUTION: Do not exceed the system voltage . Increase the rectifier’s output voltage to the
desired set point. When the rectifier output reaches the predetermined setting, the high
voltage shutdown will activate the shunt trip on the AC circuit breaker causing the breaker to
trip which turns off the unit. To reset unit, push reset button and turn on AC breaker.
9.4 LOW VOLTAGE/DIFFERENTIAL (DIFF)
The LED illuminates when rectifier or battery voltage falls below a predetermined adjustable level. The
factory setting is 2 volts/cell (Lead) (VRLA) or 1.2 volts/cell (N.C.). The LED will stay on until the DC
voltage recovers to an adjustable preset level.
The differential between the low voltage alarm setting and the voltage required to turn off the alarm is
factory set at 8%. This can be field reset.
Consult factory for procedur e.
9.5 LOW CURRENT
The L.E.D. illuminates when the rectifier output current goes below a preset value and stays on until the
current goes above a preset value.
9.6 CURRENT LIMIT ADJUST
The current limit adjustment is factory set at approximately 115% of rated DC output current. The
adjustment provides a means of changing the rectifier current limit between 90-115% of rated output.
