SHUTDOWN FEATURES
ADDITIONAL SHUTDOWN FEATURES
The A6060 Circuit Board also incorporates the follow-
ing protective shutdown features:
LOSS OF 9-WIRE CABLE SIGNALS TO INVERTER:
On units with A6060 Circuit Board Revision “D” or
higher software, the generator will shutdown if the 9-
wire cable 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.
LOSS OF PS1/PS2 TO INVERTER:
On units with A6060 Circuit Board Revision “D” or
higher software, a loss of voltage to the inverter will
simulate a 9-wire 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.
SHORT CIRCUIT PROTECTION:
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.
DC LINK VOLTAGE GREATER THAN 600 VDC:
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.
