6.6 Indicators
The BCU has 1 LED to indicate that the power supplied to it is present, in other words, at least a
PoE link is established to the core module. In the event the LED is illuminated (steady, green), the
video display on the unit must work.
Additionally, each network-port provides Link and Activity LEDs on the rear of the unit with the
following status indications ....
Link speed (Green LED)
The LED is on when there is a link connection.
Otherwise, the LED is off.
Activity (Yellow LED)
The LED is flashing when there is activity on the link.
Otherwise, the LED is off.
6.7 Errors
Error indication: in the event the LED on the back side of the unit is ON, the display is illuminated
and showing text (buttons), but no valid (UTC) time is presented on the display, the data-link to
the core module is not functional at that time. All other errors are presented on the display.
The BCU provides an Auxiliary CAUTION relay of which the (dry) contact rating is 28V DC, 200mA
max. During a correct functioning of the VDR, the relay contacts are in the NO position. When a
CAUTION condition occurs or the VDR loses its power, the NC position is valid. (NC=normally
closed, CO=COMMON contact, NO=normally open).
6.8 Configuration
IEC61162-2 serial ports (3 off) speeds must be set during commissioning time. Please refer to
chapter ‘
Connecting to the VDR for configuration of the system
6.9 Operating instructions
The BCU is equipped with a touch screen display with day and night display mode.
