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).

| Response value RCM... | Measuring range rms | Measuring range peak | | I_{4 n} ≤0.1 ~A$ | 0...450 mA | 0...900 mA | | 0.1 ~A<I_{An } ≤0.5 ~A$ | 0...0.75A | 0...3.5A |
