ADDITIONAL SHUTDOWN FEATURES
The A6060 Circuit Board also incorporates the follow-
ing protective shutdown features:
ing protective shutdown features:
LOSS OF 12-PIN CABLE SIGNALS TO INVERTER:
The generator will shutdown if the 12-pin connector is
disconnected from the inverter when CB1 is turned to
ON.
This shutdown will occur after approximately 5-7
seconds.
The generator will shutdown if the 12-pin connector is
disconnected from the inverter when CB1 is turned to
ON.
This shutdown will occur after approximately 5-7
seconds.
LOSS OF TIM1/TIM2 INPUT TO A6060 CIRCUIT BOARD:
If Timing Winding input is lost, the generator will
immediately shutdown.
If Timing Winding input is lost, the generator will
immediately shutdown.
LOSS OF PS1/PS2 TO INVERTER:
A loss of voltage from PS1/PS2 windings to the
inverter will simulate a 12-pin signal failure and cause
a shutdown when CB1 is turned to ON.
This shutdown will occur after approximately 5-7
seconds.
A loss of voltage from PS1/PS2 windings to the
inverter will simulate a 12-pin signal failure and cause
a shutdown when CB1 is turned to ON.
This shutdown will occur after approximately 5-7
seconds.
OVERSPEED OF ENGINE:
Overspeed of the engine will result in an immediate
shutdown. This automatic generator shutdown will
occur at engine speed above 4200 rpm.
Overspeed of the engine will result in an immediate
shutdown. This automatic generator shutdown will
occur at engine speed above 4200 rpm.
SHORT CIRCUIT PROTECTION:
If the inverter senses a short circuit on the AC output
side it will automatically shut the generator down.
If the inverter senses a short circuit on the AC output
side it will automatically shut the generator down.
INVERTER OVERHEAT CONDITION:
If the inverter overheats, AC output will be shut off.
The engine will continue to run for approximately two
minutes and then shut down. The maximum ambient
temperature rating is 120°F.
If the inverter overheats, AC output will be shut off.
The engine will continue to run for approximately two
minutes and then shut down. The maximum ambient
temperature rating is 120°F.
DC LINK VOLTAGE GREATER THAN 600 VDC:
If DC link voltage exceeds 600 VDC, the inverter will
shut off AC power output.
If DC link voltage exceeds 600 VDC, the inverter will
shut off AC power output.
DC LINK UNDER-VOLTAGE SHUTDOWN:
If DC link voltage drops below 100 VDC, the inverter
will shut off AC power output.
If DC link voltage drops below 100 VDC, the inverter
will shut off AC power output.
