(Condition 1: To apply the fault exclusion of mechanical structural parts including the actuator
→ Make sure to use the product within he product specification range described in his
manual and the version of the manual provided wi h the product.)
(Condition 2: Documentation of the reason for the machine/equipment manufacturer to have
applied the fault exclusion based on ISO13849-1, ISO13849-2 or IEC62061.)
S1: HS1C-24 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.
