Quick Start Instruction E5CC OMRON On-Off: The default setting of the controller as an ON-OFF controller. This ensures a limited extent of switching on the output, but results in less accurate control. This control does not take disturbances into account and is not ЁintelligentЁ Thermocouple: A thermocouple is a sensor that transmits a millivolt signal, which cannot be tested for continuity. Caution: a thermocouple can only be extended by specially designed couple extension cables Solid-state relay : Also called SSR. This relay is specifically developed for frequent switching. It has no moving parts or mechanical contacts but can also break or short- circuit.
SSRs are often used in temperature controls set as PIDs. Control output: The control output is the output that controls the process. This output is switched on when temperature needs to be controlled Overshoot: Temperature overshoot occurs when the temperature rises above the set value when the controller stops heating too late. In an ON-OFF control the overshoot will be larger than in a PID controller. Undershoot: Temperature undershoot occurs when the temperature falls below the set value when the controller starts heating too late. In an ON-OFF controller the undershoot will be larger than in a PID controller. AT or AutoTune:
Autotune allows you to easily calculate and set the correct P, I, and D parameters. The process is learnt by the controller itself Hysteresis: Hysteresis is the value at which an output must be switched on or off. It is used in alarm contacts and ON-OFF controllers. Decimals: Decimals are the numbers after the decimal point, e.g. 10.8 degrees. 25
