151 Non-Contact Safety Switches CES-AR/CET-AR Subject to technical modifications; no responsibility is accepted for the accuracy of this information. Connection examples CET-AR Important: To achieve the stated category in accordance with EN ISO 138491, both safety outputs (OA and OB) must be evaluated. Connection of a single CET-AR, version without feedback loop If a single CET-AR is used, connect the switch as shown in figure below. The OUT output can also be connected here to a control system as a monitoring output. The switch can be reset via the RST input. To do this, a voltage of 24 V is applied to the RST input for at least 3 seconds. The supply voltage to the switches is interrupted during this time. The RST input must be connected to 0 V if it is not used.

To integrate the subsystem in a category 3 or 4 structure, it is necessary to monitor the downstream load (the feedback loop must be monitored). If the CET-AR with feedback loop is used, it must be at the last position in the switch chain (see figure showing connection of a CET-AR in a CES-AR switch chain). These examples show only an excerpt that is relevant for connection of the CET system. The example illustrated here does not show complete system planning. The user is responsible for safe integration in the overall system.
