Chapter 2 Safety information 7
2 Safety information
• Before installing, starting up and using the indicator and the weighing instrument, please read
this operating manual attentively.
!
• Always comply with the safety information.
• When using the weighing instrument in legal-for-trade applications, ensure that the official veri-
fication and sealing marks are intact. The electronic verification seal number displayed must
be the same as the number on the main rating plate. The electronic verification seal must not
have been destroyed.
• If verification or sealing marks have been damaged, if the verification seal number displayed
is not the same as the number on the main rating plate, or if the electronic verification seal has
been destroyed, the weighing instrument is no longer deemed to be verified and may no longer
be used in legal-for-trade applications. If there is a risk of the weighing instrument being used
unwittingly or inadvertently in legal-for-trade applications, it must be taken out of operation.
2.1 Mains connection
• The indicator may be connected only to a properly installed socket outlet. The socket outlet
must comply with the local regulations.
• Before connecting the indicator to the mains, ensure that the voltage information on the data
plate corresponds to the mains voltage. If this is not the case, the indicator may not be operated
on mains electricity. If the Indicator is operated at the wrong mains voltage, there is a risk of
electric shock.
STOP
• The Indicator may not be used if the power cord is damaged. If the Indicator is used with a
damaged power cord, there is a risk of electric shock.
2.2 Arc welding work
!
• When carrying out arc welding work on the weighing instrument or the weighing platform,
always disconnect the appliance from the mains. Even if the appliance has been disconnected
from the mains, always ensure that no welding currents are allowed to flow through the load
cells.
2.3 Handling
• The keypad is designed for hand operation only. Never use pointed objects for key operation.
• If the keypad or display window is damaged, the weighing instrument may not be used and
must be disconnected from the mains. The keypad must be replaced by our customer service
or a specialist firm. For as long as the keypad or display window are damaged, the indicator
must be protected against moisture, liquids and dust, in particular.
• There are no operating components inside the enclosure. The device enclosure may be ope-
ned only for service or repair purposes.
2.4 Cleaning
• Always use mild cleaning agents to clean the indicator. Solvent-containing, aggressive and
abrasive cleaning agents may not be used.
• The appliance enclosure is rated to IP67. Ingress of water jets is not possible from any direc-
tion. The IP67 rating does not prevent the ingress of moisture when a high-pressure cleaner is
used. Never spray the enclosure using a high-pressure cleaner.

2.5 Storage
• The weighing platform must not be subjected to a load while the instrument is in storage.

Chapter 4 Setup 11
4 Setup
4.1 Desktop setup
The indicator is supplied for use on a desktop as stan-
dard.
Four rubber feet have already been attached to the
underside of the enclosure.
The device can be positioned on a level surface without the need
for additional installation work. The angle of the enclosure creates
a favourable angle for reading off the LC display.
4.2 Wall setup
A metal bracket is supplied for mounting the device on a wall.
Before the bracket is screwed to the enclosure,
it can be used as a drill template.
When the device has been mounted the top
edge of the enclosure is situated roughly level
with the drilled holes.
Two holes have to be drilled 120 mm apart. Use
appropriate wall plugs and screws according to
the condition of the wall.
Insert the screws into the wall plugs and tighten
until the screw head is about 7 mm from the
wall.
Screw head max. 10 mm ∅
Screw shaft max. 5 mm ∅
Attach the metal bracket to the rear of the en-
closure with two nuts on the (M4) threaded pins.
The cable glands are situated on the opposite
side of the enclosure.
Suspend the device with the metal
bracket on the two retaining
screws in the wall.
The angle of the enclosure creates
a favourable angle for reading the
LC display.

4.4 Switching between desktop and wall setup
Depending on the setup the control and viewing direction will change.
When a device has been setup for use on the desktop, the keypad and the LC display will be up-
side down if it is installed on a wall.
The same effect is encountered if you use a device setup for wall installation on the desktop.
As the enclosure cover is designed symmetrically and the display is positioned exactly in the midd-
le, the cover can be rotated with the keypad. The membrane keypad will then be in the correct
position for use.
The LC display is located on the main board and cannot be rotated.
However, the components of the LC display are also symmetrically designed.
Changing the socket for the membrane keypad ribbon cable when rotating the enclosure cover
will adjust the viewing direction automatically.
For special power-up procedures the viewing direction can also be adjusted by changing the po-
sition of a jumper. The position of this jumper should always match the device setup (desktop/
wall).
!
The enclosure cover may be rotated only with special care and in strict compliance with the follo-
wing safety information.

Chapter 4 Setup 13
4.5 Rotating the enclosure cover
4.5.1 Safety information
Persons working on the electronics must discharge themselves beforehand and ensure they do
not become charged again while working.
An anti-static wristband must be used.
£Shut down the device.
£Remove the mains plug or cut off the power (switch, fuse) and safeguard against inadvertent
reconnection.
£Put on anti-static wristband.
£Connect anti-static wristband (e.g. to earthing contact of a socket outlet).
£Touch the indicator enclosure to place yourself at the same potential.
£Perform the work on the electronics.
STOP
Make sure you comply with the safety information. Improper handling of electronic assemblies can
result in their being destroyed.
No guarantee can be assumed for any defects that occur in this case.
STOP
When opening up the device ensure no metal objects (screws, nuts, washers, paper clips, etc.)
find their way inside the enclosure.
4.5.2 Opening the enclosure
!
Shut down the device.
Cut off the power supply, remove the mains plug.
Do not restore the power supply until the device has been closed again.

14 82comfort • Operating Manual
Lift off the enclosure cover perpendicular to the device.
!
Caution!
The keypad ribbon cable is plugged into the main board. Do not tear off the ribbon cable or remove
forcibly from the connector. Do not bend or kink the cable.
The glued-in enclosure gasket is located on the inside
of the cover. To ensure the correct distance between
the gasket flange and the cover when closing the en-
closure, spacer sleeves are inserted on the threaded
pins. The spacer sleeves must not be mislaid.
4.5.3 Disconnecting the keypad
Desktop setup
The plug-and-socket connection is situated to the bottom
right on the main board.
The ribbon cable is not clamped in the connector.
Lift the ribbon cable vertically out of the connector.

5.2.2 Verification seal destroyed
STOP
The electronic verification seal has been destroyed.
The weighing instrument is no longer verified and may not be used in legal-for-trade applications!
5.2.3 Incorrect dongle number
STOP
The dongle is an electronic device in the terminal box of the weighing platform. It comes with an
identification number that is checked by the indicator on power up.
The number of the connected weighing platform is not the same as the number recorded during
adjustment. The wrong weighing platform has been connected.
The weighing instrument is no longer verified and may not be used in legal-for-trade applications!
5.3 Switching off
Device is in weighing mode
£Press to switch off.
If the indicator is going to be left switched off for several days, remove all loads from the weighing
platform!

Always use the key to switch off the device. Never switch off the device by cutting off the po-
wer supply!

Note
Instead of being written straight to the permanent memory, unstable and rapidly changing data re-
mains in the volatile memory for a few milliseconds. The write cycle itself also takes a certain time.
When the power is disconnected there is therefore a risk of this data being saved incorrectly or
not at all, and other data may also be damaged.
When the device is switched off using the key, the data in the volatile memory is written to the
permanent memory and the write cycle is terminated correctly before the power is shut off, thus
guaranteeing reliable data storage.
