
Tarp system does not function and a red/orange flashing light is present on the
RF keypad, indicating an error code. See error code explanations below:
a) Three flashes indicates an Overheat Protection issue. This typically occurs if the system has been started
and stopped rapidly in a short period of time. Also, it can indicate increased drag in the tarp system causing
increased amperage. Re-check the tarp system after a cool down period.
b) Four flashes indicates an Over Voltage Protection issue. Using a voltmeter, check the tractor batteries
& alternator for voltage exceeding 15.5 volts.
