Fault Description

The CCR has determined that it is trying to drive current into an open circuit. This fault will occur when the output voltage increases but the output current does not scale to the selected setting. This fault will generally occur only if there is a problem with the airfield circuit or at a new installation.

Attempt to Correct

If this error occurs during CCR installation:

 Refer to: Adjust the Open Circuit Duration

If this error occurs during normal operation it must be determined if the issue is with the CCR or airfield circuit.

• Put the CCR in Local mode, and then disconnect CCR supply power.
• Within the CCR, install a wire jumper, or pull an S-1 Cutout handle, like described in Terminating CCR Connections.
• Re-energize the CCR, and turn it on to the first brightness step.
• If the CCR continues to present the fault, contact Airport Lighting Company. Otherwise, consult an electrician to diagnose problems with the airfield circuit.
