Operator Control Instruments and Signal Indicators

Control instruments and signal indicators are used to control automated processes or to start or stop a machine. In case of “imminent danger”, i.e. in an emergency, the emergency power off (EPO) and emergency stop switches or push-buttons are used.
In the event of an operating failure or an interruption, the display signals alert the operators to prevent that anybody gets hurt or to avoid the operating failure to remain undetected.
