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.
