The parameters required for the alignment and the proper functions of the control board are stored in
an EEPROM (9). This EEPROM retains its programmed data without external supply voltage.
16.2 Power Supply Box
The power box contains a mains adaptor (15), which is responsible for the power supply of all elec-
tronic circuits. The division of the wiring of the whole system takes place here. The wall control may
be connected to a monitor, an external PC system (Control) and the wiring for the light in the support
arm.
There is a switchover option for 115V~ / 230V~ on the mains adaptor circuit board (15). To access
it, open the housing and bring the slide switch on both circuit boards into the corresponding desired
position.
Safety Power is also brought into the power supply box directly as 24VDC. Should the mains power
fail, an internal relay will switch over to supply the safety power to the light.
Since a system always consists of two independent lights, as well as a camera, two individual mains
adaptors and a connection for a potential camera have been provided. Should a camera be retrofitted,
the system can be expanded by simply plugging in or screwing in a video demodulator (16).
The electronic control system communicates through the CAN interface (8). When a camera is added,
the CAN bus is looped over the video modulator (21) and then led over the support arm system (20)
to the power box. The bus reaches the support arm system directly when no camera is added. The bus
is then led over the mains adaptor (15) of the camera demodulator (16) to the terminal (18).

2. Check the Power output on L1 and L2 by doing the following:
WARNING To avoid the risk of electrical shock, all service must be provided by autho-
rized personnel.
a. Set multimeter to VDC mode.
b. Insert multimeter leads as shown in Figure 2.
