SECTION 11
Connection to the Machine Control Circuit
!WARNING
This product is designed for use on a 24 VDC, negative ground (protective
earth) electrical system only. Never connect the MS4800 system to a positive
ground (protective earth) system. With a positive ground (protective earth)
wiring scheme, certain simultaneous shorts of both safety outputs may not be
detected and the guarded machine may not stop, resulting in severe operator
injury.
!WARNING
Never use only a single safety output to control the machine. Should this sin-
gle output fail, the machine may not stop, resulting in severe operator injury.
The machine must be connected using both safety outputs.
The table below references Pin Numbers, Wire colors and signal names being
used with the MS4800 system.
The primary cables for the MS4800 system are industry standard non-
shielded cables with an M12 female connector. The receiver and transmitter
incorporate a 0,3 m pigtail with an M12 male connector.
We recommend to use the F39-JMR and F39-JMT cables to connect the
MS4800 system to the machine control system.
