See OPERATOR INSTRUCTION section for LED indicator definitions:
A. Verify the status LEDs:
•
AC FAIL
should be
ON
. If not, the DC output may be open or reversed, or the battery may be
extremely discharged.
•
BATT FAULT
should be
OFF
. If it lights, check for reversed polarity of the DC wiring.
•
The
DC LOW
(Low Battery) LED may be either on or off, depending on the battery’s state of charge.
•
All other LEDs and the meter display should be off.
•
If the
DC HIGH
LED is on, check battery voltage jumper setting.
B. Apply AC power by closing the branch circuit breaker and any other disconnect devices.
C. The meter display should light immediately after power on. The green
AC/ ON
LED should be lighted. If a temperature sensor is present, either internal or remote, the green
T-COMP
(Temperature Compensation) LED should be lighted.
D. If the
BATT FAULT
LED lights when AC is applied, this indicates that the battery voltage does not agree
with the
Range
jumper setting. The charger is interlocked, and will not operate in this condition.
Disconnect AC power, then correct the jumper setting or battery voltage before proceeding.
E. After a short delay (typically 10 seconds or less), the charger will produce output.
F. If the meter display jumper is selected to read Amps or automatic Volts/Amps:
•
Current should be close to 10A if the battery requires recharging. If automatic boost is enabled, the
BOOST MODE
LED may light, in which case the battery will be charged until it reaches 106% of the
float voltage. If boost is disabled, the green
FLOAT MODE
LED should be on and the battery will
charge until it reaches the float voltage setting.
•
Output current will be low if the battery is fully charged, possibly too low to read on the meter. This is
normal, provided the correct charging voltage is present. The green
FLOAT MODE
LED should light
when output current is below approximately 9 A (5A for single alarm).
12. CHECK OUT
* Active only on five alarm models - see page 3 for model number breakdown
*Red for low battery voltage
Red for low or missing AC input
Green for normal voltage (float charge)
Yellow for boost voltage (fast charge)
Red for open, wrong voltage, or reversed battery
Green for normal AC input
*Red for excessive battery voltage
Red for internal charger failure
DC Volt/Amp Meter Display
Green for temperature-corrected charger voltage
