P2HZ X1 Introduction Validity of documentation This documentation is valid for the product P2HZ X1. It is valid until new documentation is published. This operating manual explains the function and operation, describes the installation and provides guidelines on how to connect the product.
Safety Intended use The two-hand control relay P2HZ X1 meets the requirements of EN 574 Type III C. It forces a press operator to keep his hands out of the hazardous area during the dangerous closing movement, so avoiding hand injuries.
Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120 VDC) are present on the unit, connected control elements and sensors must have a rated insulation voltage of at least 250 V. Operating Manual P2HZ X1 20124-EN-06...
– Relay failure – Contact welding – Coil defect on a relay – Open circuit – Short circuit Block diagram/terminal configuration Types: DC : 24 VDC; Order no. 774340 : 26 VDC; Order no. 774341 Operating Manual P2HZ X1 20124-EN-06...

Safety contacts 13-14, 23-24 and 33-34 are opened redundantly, auxiliary contact 41-42 is closed. – The LED "CH1" or "CH2" goes out. – A low signal is present at the semiconductor output switch state Y32. Operating Manual P2HZ X1 20124-EN-06...
A high signal is present at semiconductor output Y35 if the supply voltage is present and the internal fuse has not blown. Operating modes Dual-channel operation with detection of shorts across contacts: Redundant input cir- cuit, P2HZ X1 detects – earth faults in the start and input circuit, –...
The power supply must comply with the regulations for extra low voltages with protect- ive electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410. Ensure the wiring and EMC requirements of EN 60204-1 are met. Operating Manual P2HZ X1 20124-EN-06...
Open the safety contacts (switch off output) and start the device again, so that the internal diagnostics can check that the safety contacts open correctly for SIL CL 3/PL e at least 1x per month for SIL CL 2/PL d at least 1x per year Operating Manual P2HZ X1 20124-EN-06...
Safety contacts of channel 2 are closed. Faults – Interference Contact malfunctions: If the contacts have welded, reactivation will not be possible after the input circuit has opened. Dimensions in mm 75 (2.95") 87 (3.42") (1.77") Operating Manual P2HZ X1 20124-EN-06...
