Faults - Pilz PSS Series Operating Manual

Please note:
• Safety-oriented input signals must operate in normally energised mode.
• Make sure that in the user program the "0"-Signal of the module will
switch-off the relevant outputs.
• Connecting one "0 V"-terminal is sufficient.
• Neighbouring inputs must not be assigned the same pulse.
• Copper wiring should be used that can withstand temperature of 75 °C.
• Torque setting on the screw terminals should be to 0.5 ... 0.6 Nm.

Faults

If a fault in one of the modules or a wiring-error is detected, the controller
goes into a STOP condition, switches off all the outputs and sends a
message to the display. The display on the programmer's error stack can
be used to locate the error.
