FL MGUARD RS2000 TX/TX-B
106
PHOENIX CONTACT 105656_en_05
Service contacts up to firmware version 8.0
Signal contact (signal out-
put)
The signal contact monitors the function of the FL MGUARD RS2000 TX/TX-B and thus en-
ables remote diagnostics.
The FAULT LED lights up red if the signal output is open due to an error.
The voltage at the signal contact corresponds to the supply voltage applied. The following
is reported when monitoring the output voltage:
– Failure of the supply voltage.
– Power supply of the FL MGUARD RS2000 TX/TX-B below the limit value (supply volt-
age lower than 11 V).
– Link status monitoring of the Ethernet connections, if configured. By default upon deliv-
ery, the connection is not monitored. Monitoring can be activated (on the web interface
under “Management >> System Settings >> Signal Contact”).
– Error during selftest.
During a restart, the signal contact is switched off until the FL MGUARD RS2000 TX/TX-B
has started up completely. This also applies when the signal contact is manually set to
“Closed” under “Manual settings” in the software configuration.
