Safety Outputs (OSSDs)
!WARNING
This product is designed for use on a 24 VDC, negative ground (protective
earth) electrical system only. Never connect the MS2800 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.
The MS2800 system receiver supplies two independent PNP type safety out-
puts to provide run/stop signals to the guarded machine. In the MACHINE
RUN state, the safety outputs are electrically conducting and source 625 mA
of current at 24 VDC. In the MACHINE STOP state, the outputs are not elec-
trically conducting.
8-2
Auxiliary Output
!WARNING
Do not use the auxiliary output or external indicator output for safety applica-
tions. Human body may not be detected when MS2800 system fails, resulting
in serious injury.
This is not a safety output. The MS2800 system supplies one auxiliary output.
The configuration of this output is "PNP follow". So the signal on the auxiliary
output is similar to the status of the OSSD outputs. It will source up to 100 mA
at 24 VDC.
