Sensor system
Connection of sensors
Up to two different sensors (e.g. traffic tailback warning, ice warning)
can be connected directly to the master board of the system. A
voltage between 5 and 30V can be applied to the inputs. Power
consumption at an input voltage of 24V is approx. 4 mA. The function
of the sensor input and the image selection is programmed by the
remote control
Sensor activation
The symbols to be displayed with active sensor must first be loaded.
Afterwards, select the "
Link"
menu item in the settings menu (
[F2]
function key) with the arrow keys
[
]
,
[
]
on the remote control and
confirm with
[OK]
.
Then select the sensor (1…4) to be programmed
under the "Sensors" menu item.
After the sensor selection, select the "Active" menu item and confirm
with
[OK]
. Now the sensor is activated.
Sensor deactivation
"Time min."
Delay time after switch off in minutes (0-60).
0 = no delay, sensor switches off immediately.
"Create"
Current image sequence for switching off the
sensor is taken over. Delay time is active.
"All off"
All images switch off after sensor deactivation
and expiration of the delay time.
"Previous"
Old images from the period before sensor acti-
vation and after expiration of the delay time are
reloaded.
An active sensor can be recognised from the switch symbol
(special keys
[S1]
and
[S2]
).
It is not possible to load other symbols in this case.

Fault displays
Low voltage battery
The yellow LED on the right above the battery symbol signals that
the batteries of the system are 80% depleted. When using new GEL
batteries with 210 Ah operating times* up to 2 hours can be reached
after signalisation. The LED also lights when the battery integrated in
the radio remote control Pro-Remote is depleted. The remaining time
can be significantly reduced for used and not properly maintained
batteries.
* operating time at 20°C
Fault on the device
In the case of all other malfunctions not related with a low voltage
supply, the red LED on the left above the Attention sign lights.
Calling up fault information
Information on all faults can be called up with the
[F1]
function key.
The first display after pressing
[F1]
indicates the component on
which the fault has occurred (e.g. "Remote control" or "Sign 1").
Further detailed information on the type of fault can be requested by
selecting with
[
]
,
[
]
and confirming with
[OK]
.
