The contacts of the motor thermostat and Brush Wear must be N.C.
The Drive interprets a voltage at Terminals 12 & 13 as a normal
expected condition. This input CANNOT be masked.

4. Wiring the Fault/Alarm Reset Circuit

This input clears fault and/or alarm indicators and resets the circuit.
As shown in Figure 2.27 the Fault/Alarm Reset circuit requires a
N.O. operator device that closes to cause a reset. This input can be
masked using the [Fault Reset Mask] (P. 205) or [Logic Mask]
(P. 207).
