4.5 STATUS/ALARM INDICATORS
Alarm Relays
Dual Form “C” contacts are rated for 28 VDC at 2 amperes for the low current, low DC voltage, high DC
voltage, high voltage shutdown, blown DC protection, summary and load shore. All alarms have adjustable
time delay on energize.
AC “ON” Indicator
A green light emitting diode (LED) indicator illuminates to indicate AC voltage is present to the rectifier.
High-Voltage Alarm Indicator
A red LED indicator blinks to indicate that rectifier output has exceeded the preset high-voltage set point.
This alarm condition will also trigger the summary “failure” alarm contacts.
Low-Voltage Alarm Indicator
A red LED indicator blinks to indicate that the rectifier output has dropped below a preset voltage set point.
This alarm will also trigger the summary “failure” alarm contacts.
Low-current Alarm Indicator
A red LED indicator illuminates to indicate that the rectifier output current has fallen below .5% of rectifier
rated DC output. This alarm may also trigger the summary “failure” alarm contacts provided “YES” is
selected in the calibration routine if low current is a failure condition.
Summary Fail Alarm Indicator
A red LED illuminates to indicate that a failure has occurred which may disable the rectifier. The conditions
which will produce a summary failure indication include: low current*, low output voltage or high output
voltage. 2 form “C” contacts are provided for connection of external alarms.
* - Provided low current is selected for summary alarm condition.
Float Indicator
A green LED illuminates to indicate that the rectifier is in the float mode of operation.
Equalize Indicator
A yellow LED illuminates to indicate that the rectifier is in the equalize mode of operation.
DC Blown Fuse Indicator
A red LED illuminates to indicate that the main DC protection device has opened.
Adjustments are provided for high voltage, low voltage, low current, and high voltage shutdown.
See Section 9 “ALARM LIGHTS”.
