26 EMX4i User Manual 710-14888-00C
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.
The thermistor input is disabled by default, but activates automatically
when a thermistor is detected. If thermistors have previously been
connected to the EMX4i but are no longer required, use the Thermistor
Reset function to disable the thermistor. Thermistor Reset is accessed via
the Setup Tools.
Reset/Starter Disable
The reset input (10, 11) is normally closed by default. The EMX4i will not perform a
start if the reset input is open. The display will show "Not Ready".
If the reset input opens while the EMX4i is running, the starter will remove power
and allow the motor to coast to stop.
The reset input can be configured for normally open or normally closed
operation. Use parameter 7I

.
Start/Stop
The EMX4 requires two-wire control.
Reset
Start/Stop

is set to Digital Input.
Programmable Inputs
The programmable inputs (13, 14 and 13, 15) allow external equipment to control
the starter.
The operation of the programmable inputs is controlled by parameters 7A~7H.
