Unused control terminals should not be used as jumper points as
they may be internally connected, causing damage to the unit.
Verify that the ratings of the output devices and the inputs as
specified in Chapter 6 are not exceeded.
Electric power in industrial environments contains a certain
amount of noise in the form of transient voltage and spikes. This
electrical noise can enter and adversely affect the operation of
microprocessor-based controls. For this
reason we strongly recommend the use of shielded
thermocouple extension wire which connects the sensor to the
unit. This wire is a twisted-pair construction with foil wrap and drain
wire. The drain wire is to be attached to earth ground at the
sensor end only.
