Motor Thermistor
Motor thermistors can be connected directly to the EMX4e. The soft starter will trip
when the resistance of the thermistor circuit exceeds approximately 3.6 k
Ω
or falls
below 20
Ω
.
The thermistors must be wired in series. The thermistor circuit should be run in
screened cable and must be electrically isolated from earth and all other power and
control circuits.
NOTE
The thermistor input is disabled by default, but activates automatically
when a thermistor is detected. If thermistors have previously been
connected to the EMX4e but are no longer required, use the Thermistor
Reset function to disable the thermistor. Thermistor Reset is accessed via
the Setup Tools.
