12.4 Signal Transmitter/ Reed Contact
12.4.2 Application / Function
The signal transmitter, in conjunction with products from Medenus GmbH, is used for monitoring
the position (position closed or open) of the safety shut-off valve via remote display.
A built-in neodymium magnet in the pull knob of the SSV and a set switching distance to the reed contact cause a sensor
to query the position of the safety shut-off valve and to transmit a signal via remote display. If the SSV drops into the
closed position, the switching distance will be exceeded and the sensor will lose the signal. This guarantees continuous
monitoring of the SSV control devices.
