GENERAL INFORMATION
Explanation of the LED display
Battery change
Temporary interruption of operations
The control housing of every traffic signal contains multi-coloured LEDs which
provide the following information:
LED yellow – not on = Battery full
LED continuous yellow = Battery warning from approx. 10.5V
LED flashing yellow quickly = Battery flat (signal dark);
Change battery within 5 minutes as otherwise
the programmed data will be deleted.
LED flashing yellow slowly = Manual mode flashing yellow
LED continuous red = Manual mode continuous red
LED flashing red = Red defect (bulb);
Please replace the bulb in the red chamber!
LED red/green (orange) = Manual mode dark (lamps off).
When traffic signals change from green to yellow, the green LED at the signal head
programmed as signal 1 flashes once, twice at signal 2, three times at signal 3, etc. This
shows you how the corresponding signal head has been programmed.
When the battery has a voltage level of approx. 9V, the corresponding signal head
switches the lamps off. Replace the "flat" battery with a fully charged 12V/170 Ah
battery. (The battery/ies are accommodated in the battery casing at the bottom). The
systems continue to work normally after changing the batteries. Changing the battery
must not take longer than 5 minutes to avoid having to reprogram the signals!
If the systems are temporarily decommissioned without deleting the program
workflow, both signals have to be set to "dark" first. The batteries must not be
disconnected. The program workflow continues internally, running on the connected
power supply.
