ENCODER FOR LCH CONTROLLER

Controls of all kinds are integral parts of restaurant equipment operation. A control is a switch or other device by which a machine is regulated. A control may be manual or automatically operated. An electro-mechanical control typically consists of multiple relays, timers, and/or counters wired together on an enclosure panel. Electro-mechanical control is also referred to simply as "Relay Control", which is a more accurate term since solid state electronic relays, timers, and counters are standard components. Contactors, motor and compressor starters, valves, thermostats, and other output devices are used to turn on/off motors, indicator lights, heating elements, and other components used in the equipment.

An encoder is a sensor which turns a position into an electronic signal. There are two forms:

• Absolute encoders give an absolute position value.
• Incremental encoders count movement rather than position. With detection of a datum position and the use of a counter, an absolute position may be derived.

The position may be measured as either linear or angular position:

• A Linear encoder converts linear position to an electronic signal
• A Rotary encoder converts rotary position to an electronic signal
