General Troubleshooting
W4B-120C is not powering up
•
Confirm that all circuit breakers and switches in the system are closed
•
Check all fuses
•
Check for loose wiring connections and wiring continuity
•
Verify that the battery voltage is not below 9Vdc
•
Verify that the battery power connection is not reversed polarity
Troubleshooting Charging
•
Over-charging or under-charging the battery
•
DIP switch settings may be wrong
•
Over-temperature condition is reducing the charging current (heat sink cooling may
be blocked)
•
Voltage drop between W4B-120C and battery is too high
•
Load is too large and is discharging the battery
Not charging the battery
•
DIP switch settings may be wrong (check each switch position carefully)
•
Circuit breaker or disconnect is open
•
Reversed polarity connections at the PMG terminals (PMG: Permanent Magnet Gene-
rator)
•
Short circuit in the wind system has eliminated part of the wind power output
• Wind energy is not providing enough current
•
Battery is failing and cannot hold a charge
Troubleshooting Diversion Control
•
Diversion load is too small so PWM reaches 99%
•
Diversion load is burned out so PWM reaches 99%
•
Diversion load is too large so W4B-120C faults on overcurrent
•
An overtemperature condition may have caused the load to be disconnected
•
Voltage drops between the W4B-120C and battery are too high
