Trouble shooting: Faults and Solutions
This section explains how to correct faults:
Over-voltage (OV)
The OV cut-off is at 56V. Set the
charger’s limit below
56V to prevent an OV event. If the voltage
exceeds 56V, the module shuts down and locks.
The module unlocks
when the module’s surface charge is
cleared, and the voltage drops below
54V. The event can be repeated if the charger is still ON and operating in the same condition.
Procedure
:
C
heck the charger’s
upper cut off limit and ensure it is set below 56V.
Under-voltage (UV)
The UV cut-off is 44V. If the voltage goes below 44V, the module shuts down and locks. The
module unlocks when the voltage goes above 44V. The event can be repeated if the load is still
ON and operating in the same condition.
Procedure
:
Check for the operating load lower cut off limit and ensure it is above the lower
threshold limit of 44V.
Over-Current (OC)
OC occurs when the current goes above 296A or when the module is short-circuited. In this event
the module shuts down and locks.
Procedure
:
Switch off the module and check the voltage across the module terminals to find
whether it is a short circuit. In case of short circuit, check the operating circuitry and clear the
short circuit. The module can be unlocked in 30 seconds after the current goes below 296A.
Over-Temperature (OT)
OT occurs when the module temperature goes above 75°C. In this event, the module shuts down
and locks.
