Warning Description


The CCR is providing output current, but the voltage is minimal.
TURN The CCR providing output current, but the voltage is minimal.
The most likely cause is an S-1 Cutout shorting the output, or a forgotten wire jumper used during setup/calibration.
The CCR will operate in a short, and is providing power to the output terminals.

Attempt to Correct


Always maintain safe working conditions by using appropriate personal protective equipment (PPE) where necessary.
Go into Monitor Config > Output Voltage and disable it, if the warning disappears re enable if desired and configure the appropriate threshold determined by load.
TURN OFF POWER to the CCR before modifying the output circuit.
Ensure the circuit S-1 Cutout is set for normal operation.
Open the CCR door and visually inspect for a short, such as a leftover wire jumper from installation.
If there is still a short, disconnect airfield circuit and test for a circuit short.
