Red for internal charger failure
B. FRONT PANEL LED INDICATOR DEFINITIONS AND TROUBLE SHOOTING:
*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
DC Volt/Amp Meter Display
Green for temperature-corrected charger voltage
Battery Fault Protection and Alarm:
•
The battery charger automatically checks the battery voltage before power-on startup. If the battery voltage is
either too high or too low, the charger enters a “lockout” period for approximately 10 seconds before attempting
an automatic restart.
•
The “JUMP” feature (described in Section 11-G in this manual) may be used to temporarily allow the battery
charger to override the lockout and start charging a low-voltage discharged battery – this override should be used
only up to approximately 5 minutes of recharge time, then the jumper should be replaced in its normal position
•
The battery charger will not start if the battery or battery cables have a short circuit, and will start automatically
with a good battery if the short circuit is removed.
•
In addition to detecting low battery voltage and short circuits, the battery charger also monitors the peak voltage
at its DC output terminals and will enter lockout if the DC cable resistance is too high or if the battery’s internal
resistance is too high
•
If a battery is connected backwards, this reverse polarity condition will keep the battery charger in lockout and it
will remain in lockout until the battery is disconnected. A reverse polarity condition will not blow a fuse; the bat-
tery charger will start and run normally when a good battery is connected with correct polarity.
•
Whenever one of these fault conditions triggers the battery fault protection circuitry as described above, the
“Batt Fault” relay and LED are both activated.
