Circuit Breaker marked "Load" will trip and charging will stop:
•
Display in Utility / Generator Modes - "SCREEN 6" (pages 43 & 44) will show the
charging stage at the time the breaker tripped
•
Display in Utility / Generator Modes - "SCREEN 4" (page 43) will show 0A and 0v
•
Display in Utility / Generator Modes - "SCREEN 5" (page 43) will show 0A for
internal charger
•
Transfer Relay will remain energized. Pass-through AC output will still be available
through the AC input breaker marked "Charger"
If AC input is subsequently interrupted or the voltage and frequency of the AC input are
not within the programmed limits or the AC input breaker marked "Charger" trips due
to overload in the AC by-pass load circuit, the unit will shut down completely:
•
Transfer Relay trips
•
LCD displays: "Fault Mode, Short Circuit"
nOte: The unit will get latched in this condition and will not switch OFF through the
ON / OFF Key. To reset, remove the DC and AC input connection, wait for 5 minutes,
reconnect and then switch ON
If the combined AC side charging current and the pass-through load current exceeds the
capacity of the Circuit Breaker marked "Charger" (40A for G4-2012 and G4-2524 and
60A for G4-3524), this breaker will trip. Charging will stop and pass-through load will
be transferred to the Inverter Section. Overload protection of the Inverter Section will be
provided as explained below against "Overload in Inverter Mode"
Electronic overload shut down in 100 ms if load is >200% of rated Continuous Active
Output Power
•
LCD displays: "Fault Mode, Fault Mode"
Electronic overload shut down in 20 sec if load is >150% of rated Continuous Active
Output Power
•
LCD displays: "Fault Mode, 150% overload"
Electronic overload shut down in 60 sec if load is >130% of rated Continuous Active
Output Power
•
LCD displays: "Fault Mode, 130% overload"
Electronic shut down in 15 min if load is >110% of rated Continuous Active Output
Power (When started in cold condition)
•
LCD displays: "Fault Mode, 110% overload"
Shut down due to tripping of Circuit Breaker marked "Load" due to continuous
overload > the rated capacity of the breaker (30 A for G4-2012A, 35A for G4-2524A
and 40A for G4-3524A)
•
LCD displays: " Fault Mode, Short Circuit"
Shut down if H-Bridge Mosfet heat-sink temperature ≥ 105° C for more than 30 sec.
Shut down immediately if temperature is ≥ 140°C
•
LCD displays: " Fault Mode, Over - temperature"
Shut down if main transformer temperature is ≥ 140°C
•
LCD displays: "Fault Mode, Over - temperature"
If main transformer temperature is ≥ 120° C, charger current is reduced to 50%
