Part No. 1305686GT Scissor Lifts 35
Inverter type 2
1 right fault LED
2 left fault LED
3 25V LED
4 21V LED
3 Connect an appropriate power tool to the
inverter. Activate the tool.
Inverter type 1:
Result: Status LED blinks orange. Inverter
status is On or Off.
Result: Status LED blinks red. Inverter fault.
Result: Display LED blinks green. DC volts.
Result: Display LED blinks red. Power output.
Inverter type 2:
Result: The power tool should operate. There
may be a brief (0.5 second) delay if the power
tool has not been used in the previous
10 minutes.
If the left fault LED (REV_POL) is illuminated,
the inverter is connected to batteries with the
incorrect polarity. Correct the polarity issue
with the red wire to battery positive and the
black wire to battery negative. The inverter
will then operate correctly and begin
supplying AC power.
If the right fault LED (123) blinks one time, the
power draw is too high. The tool being used
requires too much power to operate or is
being used at or near the limit of the inverter
for an extended period of time. Reduce the
power draw. The inverter will then operate
correctly and begin supplying AC power.
If the right fault LED (123) blinks two times,
the Ground Fault Interrupt (GFI) has been
activated. A short circuit or partial short exists
between the AC hot and ground in the tool or
outlet. Check the tool for burnt, chafed,
corroded and loose wires, and inspect the tool
for internal moisture. Correct the short circuit
or moisture issue OR inspect the wiring in the
power-to-platform box. The inverter will then
operate correctly and begin supplying AC
power.
If right fault LED (123) blinks three times, the
inverter is overheated. Allow the inverter to
cool. The inverter will then operate correctly
and begin supplying AC power.
If the battery 25 volt fault LED (25V) blinks
one time, the battery voltage is over 30V.
Operate the machine to lower the voltage
level. The inverter will then operate correctly
and begin supplying AC power.
If the battery 21 volt fault LED (21V) blinks
one time, the battery voltage is less than 20V
DC. The inverter will continue to operate until
the battery voltage falls to 17.8V DC.
