NOTE
In order to avoid malfunctions or damage, all the instructions
in this section must be complied with.
Designated operational location
The equipment is intended for use on rail vehicles. It is installed in the driver’s cab.
Installation conditions
A permanently secured connection to the vehicle earth (operating earth) must be
established at the prescribed connection (earthing bolts). This requires a maximum 3 ft
(1 m) long metal braid with a minimum diameter of 0.015 sq in (4 mm2). The service
and maintenance personnel must be electro-statically discharged to protect the
operating resource.
Wiring and signal requirements
The supply voltage (battery voltage) and all related signals may not be connected to
the operating earth; otherwise the potential isolation in the device will be cancelled and
safe operation cannot be guaranteed.
Signal reference to the vehicle battery is only permitted for the supply voltage. Lines
with battery-related signals may not be fed to the unit in combination with the signaling
lines.
Shielded cabling throughout is specified for the lines of the RS-422 serial interfaces.
The shield must be applied to the side of the LCDM device by a conductive plug
housing. Preferably, the shield should be applied on both sides.
The service interfaces Ethernet, RS-232 and the USB interfaces are only for testing
and diagnosis purposes and may not be connected when the vehicle is in operation.
The braided screens of all screened cables must have an optical range of at least 85%.
The connections to the line screens shall be made appropriately in relation to EMC. All
shielding and earth connections must be connected via a broad contact surface.
Unused plugs must be covered with a cap.

 Lay the cable in such a way that the connectors are not subject to any
tension or bending.
 Insert the device into the front panel recess. Screw on the front plate with
four well fitting screws (recommended type: cylinder head screw with
hexagon nut according to DIN EN ISO 4764 (dx = 8.5 mm)).
 The device is now ready for operation and can be switched on.
8.1.3 Self-test
After the supply voltage is applied the device performs a self-test. After this
self-test, the device goes into the normal operating status.
IP-225-C
If the self-test fails, the boot-up operation is aborted. The device must then be
returned for repairs.

10.2.1 Buzzer
A buzzer (piezoelectric) is on the basic PCB inside the device (782340/782343)
resp. on the rear panel (Tbd).
Activation occurs by means of the application software.
10.2.2 Brightness control
The brightness of the display or keyboard lighting can be controlled manually or
via automatic control.
An optical sensor for registering the ambient brightness is located in the front
plate of the device.
Brightness control is assumed by the environment controller, which activates
the CCFL tubes and the keyboard lighting (LEDs) according to a configurable
control characteristic and a manually specified basic value for the brightness.
The control supported by the characteristics can be shut down and a static
brightness value can be set.

MAINTENANCE
12.1 Important Notice
NOTE
Customer intervention during warranty obligation is not
permissible.
With the exception of battery replacement as described in Chapter 12.4.1, the device
is maintenance-free.
12.1.1 Basic maintenance instructions
Preventive maintenance must be carried out by the operator during
intermission periods or during scheduled downtimes. It may never be carried
out during normal operating periods!
Preventive maintenance must be carried out by trained operating personnel.
12.2 Smallest exchangeable unit
The smallest exchangeable unit is the LCDM.
12.3 Preventive maintenance
A daily inspection is carried out within the scope of the daily operation. This includes a
visual inspection by the driver, who must confirm the self-test and any error messages.
12.3.1 Inspecting the function
Preventive maintenance is performed outside of normal operating times by the
user. This includes an inspection every two years, whereby a function test must
be carried out according to upkeep instructions. Especially the display and the
CCFL tubes must be checked for function and brightness and replaced, if
necessary.
12.3.2 Inspecting the display background lighting
The display background lighting (CCFL) is subject to physical ageing and must
be visually inspected once a year.
This inspection must focus on the display and lighting. If necessary, the CCFL
lighting must be replaced prematurely.
12.3.3 Cleaning notes
The front frame and display/touch panel of the LCDM may only be cleaned with
commercially available household or glass cleaners (dish-washing liquid).
Use of aggressive solvents (e.g. acetone, benzene, thinners, tetra
chloromethane) will cause permanent damage.
