Fault Codes
At least one fault code is present when the alarm at
the platform controls produces two short beeps
every 30 seconds for 10 minutes.
Perform this procedure with the engine off, the key
switch turned to platform controls and the red
Emergency Stop button pulled out to the on
position at both the ground and platform controls.

Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or

ALC-500 circuit board inside the platform
control box. Do not touch the circuit board.

second.
Note: When the red LED is flashing the code, the
yellow LED will be on solid.
