Safety Mat System Periodic Checkout Procedure
Verify the functioning of the safety mat monitoring system periodically to ensure proper operation (see also the machine manufacturer’s
recommendations).
WARNING:
Checkouts for Multiple Safety Devices. If more than one safety mat is series-connected to one Safety Mat
Monitor Module, run this checkout procedure individually for each mat.
1. With the machine running, apply force to the mat’s sensing area, using a test piece as described in the mat manufacturer’s literature,
or the appropriate standard. Verify that the machine stops within the expected time period.
2. Remove the test piece from the safety mat. Verify that the machine does not restart.
3. Close and then open the Reset switch (if using Manual Reset mode). Verify that the machine cycle can be restarted by normal initia-
tion.
4. Repeat for each safety mat individually.
Troubleshooting
