For drives without the monitor circuit, a normally closed temperature
sensor on the brake resistor is wired either to the elevator controller or
to a contactor. If the temperature sensor indicates an over temperature
condition, either the elevator controller or the connected contactor must
remove the source of energy from the braking resistor. This can be done
either on the AC line side of the drive or the DC side with a resistor as
shown in the following wiring diagrams.
