8.3 Operational safety of VIBROCONTROL 6000 Compact monitor
8.3.1 OK-monitoring function
The OK-monitoring function monitors the following:
♦ The power supply
♦ The microprocessor system
♦ The A/D converter
♦ The module equipment
♦ The connected sensors
When a fault occurs at one of the above, the LED is extinguished and the
associated OK-relay will change over contacts (normally-energised). The
OK-relay has potential-free contacts.
Each OK-fault is recorded in the Logbook. In the case of a serious system
error it is possible that no logbook entry will be recorded.
The OK-LED signals an error number by way of a flashing sign. Please note
the detailed information in section D „Dialogue with the User-Terminal“,
chapter „Logbook“.
Electrical voltages supplied from an external source may be connected
to the relay contacts! Please note that making contact with these
voltages at the relays may cause injury or damage, even if the power to
the VIBROCONTROL 6000 Compact monitor itself is switched off.
