4-3 Override function
WARNING
Muting and Override function can disable the safety functions of a machine. The
proper installation, checkout and operation of a machine and muting system in
accordance with all applicable laws and standards, is critical to the safe operation
of the machine.
Failure to comply with these instructions may result in severe injury to personnel.
The muting lamp for indication “active muting” or “active override” must be
positioned in a place where it can be seen from any operative point.
The TEST and RESET buttons must be positioned in such a way
- that the operator can see the protected area when he carries out reset, test, or
override operations.
- that it can not be activated from inside the hazardous area.
