Field Adjustment, Error Codes and troubleshooting
Models with trip level option A have field adjustable ground-fault-current trip level and trip
time. The factory defaults are 30 mA and 0 s. These models have a CTUB101-CTBC35P
current sensor, which has a three-position potentiometer that must be set to the correct
position depending on the RCMA420-D-2 ground-fault-current trip setting. For trip settings
up to 100 mA, the potentiometer must be rotated to the left position (pointing to 8 o’clock)
and for setting above 100 mA the potentiometer must be rotated to the vertical position (12
o’clock).
For details about protection relay settings, error codes, and troubleshooting, please refer
to the respective protection relay technical manuals, available online.
