FL MGUARD RS4000/RS2000
105656_en_05 PHOENIX CONTACT 19
Service contacts up to firmware version 8.0
The push button or on/off switch is used to establish and release a predefined VPN connec-
tion.
The output indicates the status of the VPN connection (in the web interface under “IPsec
VPN >> Global >> Options”).
Operating a connected
push button
• To establish the VPN connection, hold down the button for a few seconds until the INFO
LED flashes. Only then release the button.
Flashing indicates that the device has received the command to establish the VPN con-
nection and is establishing the VPN connection. As soon as the VPN connection is es-
tablished, the INFO LED remains lit continuously.
• To release the VPN connection, hold down the button for a few seconds until the signal
output flashes or goes out. Only then release the button.
As soon as the INFO LED goes out, the VPN connection is released.
Operating a connected
on/off switch
• To establish the VPN connection, set the switch to the ON position.
• To release the VPN connection, set the switch to the OFF position.
INFO LED If the INFO LED does not light up, this generally indicates that the defined VPN connection
is not present. Either the VPN connection was not established or it has failed due to an error.
If the INFO LED is illuminated, the VPN connection is present.
If the INFO LED is flashing, the VPN connection is being established or released.
Signal contact (signal out-
put)
The signal contact monitors the function of the FL MGUARD RS4000/RS2000 and thus en-
ables remote diagnostics.
The FAULT LED lights up red if the signal output changes to the low level due to an error
(inverted control logic).
The voltage at the signal contact corresponds to the supply voltage applied. The following
is reported when monitoring the output voltage:
– Failure of at least one of the two supply voltages.
– Power supply of the FL MGUARD RS4000/RS2000 below the limit value (supply volt-
age 1 and/or 2 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 RS4000/RS2000
has started up completely. This also applies when the signal contact is manually set to
“Closed” under “Manual settings” in the software configuration.
