the movements in case of resistance detection. They are remotely
controllable and diagnosable through the ERT interfaces in an very
easy and cost effective way.

VEENER GUIDE
Veener
The Veneer can be placed in three ways (Dimensions are specied in the
corresponding “Pattern Hole” document):
Option 1:
Veneer: In order to adjust the plastic touch button height, Venneer + Glue/
tape thickness must be previously communicated.
Option 2:
Veneer + Distance Plate: For Veneers Thickness of 1mm [0,04] or less. It will
be necessary a Distance Plate to hide the touch button copper cylinder.

18
VEENER GUIDE
Veener
The Veneer can be placed in three ways (Dimensions are specied in the
corresponding “Pattern Hole” document):
Option 3:
Veneer: The veneer thickness must be 5mm [0,16 – 0,19]. A mechanized
blind hole will be necessary to hide the touch button copper cylinder.

19
VEENER GUIDE
Veener Option 1:
- Veneer thickness must be accorded with factory
1. Check if the Veneer ts perfectly with the monitor. To join both parts
correctly it is important that the two surfaces are touching each other in
the whole length. (To make easier the adjustment the hight of the touch
button can be barely adjusted.)
2. Clean the top surface of the metal monitor housing and the bottom
surface of the Veneer.
3. Glue the Veneer. Double-side tape or glue can be used (depending on
the kind of materials are going to be jointed). The pressure applied must
not exceed 1 Kg evenly distributed on monitor surface.
Veener Option 1 Cut-Out:

20
VEENER GUIDE
Veener Option 2:
- Distance Plate material can’t be metallic. Wood or DM are advisable.
- Veneer material can’t be conductor.
1. Check if the Distance Plate ts perfectly with the monitor. The copper
cylinder can’t project outwards from the Distance Plate surface. If so, the
copper cylinder can be gently led down till aligns with the Distance Plate
surface.
2. Clean the top surface of the metal monitor housing and the bottom
surface of the Distance Plate.
3. Glue the Veneer. Double-side tape or glue can be used (depending on
the kind of materials are going to be jointed). Double- side tape or glue
used can’t be thicker than 0,2 0,25mm [0.008 0.01]
The pressure applied
must not exceed 1 Kg
evenly distributed on
monitor surface.
