Advanced Microprocessor Controller

Chapter 3: Installation

3-1 Location

Mount the instrument in a location that will not be subject to excessive temperature, shock or vibration. All models are designed for mounting in an enclosed panel.

When properly mounted in an enclosed panel using a gasket at the panel/controller interface, the keypad can be washed down with water. Do not use high-pressure fluids.

3-2 Electrical Connections

Microprocessor-based instruments require a “clean” source of power that is steady and free of noise. Electrical noise may be caused by line faults, power switching, motors, motor controllers, or power controllers containing SCR devices. Without a clean source, any microprocessor is prone to failure. If your power source is not from a clean line, your system can be protected by installing a line filter.

Where external contactors or solenoids are used with relay output instruments, an R/C Snubber Network should be used. The snubber installs easily directly across the field coil terminals of the relay or solenoid.

Do not run thermocouples, RTD’s or other class 2 wiring in the same conduit or area as the power leads. Maintain separation between wiring of sensors, process signals and other power and control wiring.
