This high-integrity system consists of an electromagnetically
coded magnetic safety switch, actuator, and control unit. The switch
and actuator can be used as a stand-alone system for low-power,
low-risk machines or with the control unit for applications requiring
a higher level of integrity. The control unit should be used when
monitoring and checking of the circuit is required. The 115/230-V
AC unit monitors and checks up to six coded magnetic safety switches
(wired in series); the 24-V AC/DC unit monitors up to fifteen coded
magnetic safety switches (wired in series). If a failure is detected
in any switch or in the control unit at a machine off/on cycle,
a stop signal will be sent to the guarded machine. The control unit
also provides monitoring of the machine's control contactor.
