Evaluate Possible Causes

e-stop switch depressed

(applies to systems configured for cab switches, which come with an e-stop switch on the control panel)

Is the e-stop switch depressed?

Battery over-discharged

Check SmartPTO battery voltage at the SmartPTO system DC-DC converter

(see “SmartPTO Voltage Test” tab for details)

System stuck in long-term-storrage (LTS) mode

Does cycling power to the system wake it up after a few attempts?

If the system won’t turn on and is sitting at or below 60% SOC (check last recorded value in telematics), it might have gone into LTS mode

System “on” (12V) power interrupted

Cab switches (if equipped)

Control panel extension harness connectors (both sides)

Cab switch extension harness connector

Battery HV Fuse

Check LVPDU fuse #2&3

HVPDU – Blown Fuse

Check harness and connectors inside SmartPTO
