ESD/EMF PROTECTION: The TCU is a microprocessor based unit. When mounting the TCU
in the machines electrical cabinet avoid placing it near sources which might produce ESD
(electro static discharge), or EMF ( electro magnetic frequencies ), such as large motor
starters or high current devices. ESD/EMF may interfere with the units operation.
The cable supplied with the sensor is fully shielded. The preferred installation method is to
connect the sensor cable directly to the TCU. If your installation requires connecting the
sensor to the TCU via a junction box/terminal strip, avoid wiring near EMF sources.
The distance of the sensor connection to the TCU should not exceed 50m (165’).
Special length shielded cables are available upon request.
Below is a basic wiring diagram for 24VDC and 115VAC machine control voltages.
