Page 48

If an error code is displayed, or odd behavior of the unit occurs, the first corrective action should be to “Cycle the Power”: Unplug the 120Vac power cord and after 5 seconds plug it in again. If this doesn’t clear the fault, proceed with the “Remedy” in the following table (Table 5).

If wire harness checking is required, examine the integrity of wires themselves, the connector housings, the integrity of the terminals as well as condition of the crimps.
