Example of wiring Diagram realizing Safety Category
S1: HS1T-VB4 Safety Switch with Solenoid
S2: Starting Switch (HW Series Momentary)
S3: Unlocking Enabling Switch
S4: Safety limit Switch
ESC: Outside start condition
K3, 4: Safety Contactor
F1: Outside fuse of safety relay module at power supply line
Note: Use the monitoring device(Safety relay module) provided the capavility to
detect a cross short circuit. The insulation of the cable has to withstand
environmental influences. If a control device other than the one shown in the
draft is used, the used control device has to be equipped with a cross short
circuit monitor.
