172
Have additional mechanical protective measures been installed which prevent reaching
under, over or around the safety field, and are they protected against manipulation?
Installation
Yes
No
Have the components of the ESPE been correctly attached and secured against loosening,
shifting and rotation after adjustment?
Is the external condition of the ESPE and all associated system components flawless?
Has the acknowledgment key for resetting the ESPE been correctly installed outside of the
danger zone, and is it functional?
Incorporation into the machine
Yes
No
Are both OSSDs incorporated in the downstream machine control?
Does the incorporation match the circuit diagrams?
Are the switching elements which are controlled by the ESPE (e.g. contactors, valves)
monitored by EDM?
Have the required safety measures to protect against electric shock been implemented
effectively?
Functionality
Yes
No
Is the ESPE effective during the entire duration of the machine’s hazardous motion?
When the ESPE is disconnected from the supply voltage, is the hazardous motion stopped
and does the acknowledgment key need to be pressed to reset the machine after the
supply voltage is restored?
If a hazardous state has been initialized, is it stopped when the ESPE is switched off, if the
operating mode or any of the function types are changed, or if switching to another safety
device occurs?
Are the specified safety functions functional in every operating mode of the machine?
Has the safety function been tested in accordance with the inspection instructions in the
operating instructions?
Are the instructions for the daily inspection of the ESPE legible and mounted in a clearly
visible position?
DANGER!
• Work on the machine must be immediately stopped if any impairment of the safety func-
tion is detected.
• Once the situation has been resolved, the effectiveness of the ESPE must be checked
again according to the checklist for initial start-up (see
