If stator temperature measurements are available, the algorithm may keep from tripping, even if the effective
current is above the ultimate trip current setting, depending on stator temperature reports. It is still important to
set a correct ultimate trip current so that the motor is well protected. If the RTDs, the module, or its
communications to the relay fail, the algorithm falls back to use of »UTC«. Also, note that if all RTD channels
are set to »
OFF
«, the algorithm reverts to the non-RTD calculation, which is based strictly on »
