PSR-CT 2.4 Inputs and outputs The sensor of the safety switch provides the following inputs and outputs via the 8-pos. M12 connector: – 24 V supply connection – 2 safety inputs – Start/reset input – 2 safety outputs (OSSD) – 1 signal output/diagnostic output 2.4.1 24 V supply connection Designation: UB, 0 V Power supply of sensor The UB and 0 V connections are used to supply the sensor with adequate voltage. When doing so, observe the requirements on the power supply.
Product description and method of operation 2.4.3 Start/reset input Designation: START Local start/reset circuit The safety switch provides two possible startup behaviors: – Autostart The sensor is switched on automatically as soon as a valid actuator is detected in the response area.
PSR-CT 2.4.4 Safety outputs Designation: FO1A, FO1B The OSSD outputs FO1A and FO1B are used for safely switching off the output circuit. The actuator moves away from the sensor when the safety equipment is opened. The actuator approaches the sensor when the safety equipment is closed. Switching on When the actuator has reached the switch-on distance, power is supplied via the sensor, and data transmission starts.
Product description and method of operation 2.4.6 Switching states Table 2-2 Switching states of the outputs The outputs have the following switching states when safety equipment is open or closed. The switch-on state depends on the selected startup behavior.
PSR-CT 2.5 Connector pin assignment The sensor connector has the following pin assignment. Use the position of the connector's coding tap as a guide.
Product description and method of operation 2.6 Coding types The sensors are available in various coding types. When combined with the coded actuator, this results in a corresponding encoding level for the safety switch according to EN ISO 14119. Fixed, unique assignment Fixcode: For the sensor to detect the actuator, the actuator must first be assigned to the sensor by means of a learning process. See Section “Startup” on page 38. The learning process can be carried out once.
PSR-CT 2.7 Active sensor areas and response area RFID transponder technology The safety switch operates with RFID transponder technology. The sensor has three active sensor surfaces: – Front (black surface) – Both surfaces on the side (with printing) Transponder field The sensor generates a transponder field with a main lobe and side lobes. The main lobe represents the defined response area of the sensor for safe switching.
Product description and method of operation 2.8 4 actuation positions Actuation positions and travel directions The sensor and actuator operate in four permissible actuation positions. The actuation position describes the orientation of the sensor and actuator towards one another, when both components are mounted to the safety equipment, and the safety equipment is closed.
PSR-CT 2.9 Limit range monitoring The moving part of a safety equipment product can settle with time. The actuator is attached to the moving part of the safety equipment product, and therefore moves out of the response area of the sensor. The sensor detects this and indicates that the actuator is within the limit range with a flashing DIAG LED. In this way, the safety equipment can be readjusted in time. See Section “LED status indicators and switching states” on page 43. 2.
Product description and method of operation 2.11 Error safety The sensor provides the following internal error safety features: – Protection against polarity reversal of the supply voltage – Short-circuit protection and short-circuit monitoring at the safety outputs – Short-circuit protection at the signal outputs – Cross-circuit monitoring between the safety outputs The sensor detects errors that have occurred with the next demand to switch on the safety outputs at the latest.
PSR-CT 3 Mounting Tip: for safety switches with fixcode or unicode evaluation, perform teaching before mounting. 3.1 Positioning and distances Observe the orientation of the arrows on the sensor and actuator in order to ensure the following: – Permissible actuation position according to illustration (A, B, C, D) – Alignment of the sensor and actuator without center offset See Section “Actuation positions and travel directions” on page 23.

PSR-CT 4.2 Fuse protection for the power supply Protect the power supply externally. Design the external fuse depending on the number of switches and the required power for the outputs. Also observe the connecting cable used.
Electrical connection 4.4 Maximum cable lengths Switch chains up to the maximum cable length as per Table 4-2 are permitted while observing the voltage drop due to the cable resistance. Also observe the maximum permissible cable lengths between two safety switches.
PSR-CT 4.4.1 Checking the planned design Check the planned design using Table 4-3 “Example table for cable lengths”. Proceed as described in the example. See “Example: determining the cable length” on page 37. The information on the cable lengths applies under the following conditions: – The requirements on the connecting cables according to Table 4-1 are adhered to.
Electrical connection Example: determining the cable length – – – – Six switches in series are to be used. The cable length from the safety relay in the control cabinet to the last switch (PSR-CT 6) is 40 m. The cable length between each individual switch is 20 m. The safety relay consumes 75 mA at each of the two safe inputs. lnom= 140 m l2 = 5 x 20 m l1 = 40 m Phoenix Contact Safety Relay ln = 20 m iout= min.
PSR-CT 5 Startup 5.1 Qualified personnel Startup information Startup may only be carried out by qualified personnel. Tips: • For safety switches with fixcode or unicode evaluation, perform teaching before mounting. • Mark sensors and actuators that belong together. • Switch chain: perform teaching-in for each safety switch before connecting in series. 5.
Startup Information on unicode sensors – – – – – The learning process can be repeated as often as required. The sensor only detects the last actuator taught in. If a new actuator (B) is taught in, the sensor blocks the code of the last actuator (A). This actuator (A) cannot be used during the next learning process. The sensor releases the blocked code again after a third actuator (C) has been taught in. Actuator (A) can be used again. Actuator (B) is now blocked.
