Cleaning And Maintenance - Kübler CODIX 541 Instrucciones De Puesta En Servicio

• The device has been designed for overvolt-
age category II. If higher transient voltages
cannot be excluded, additional protection
measures must be taken in order to limit the
overvoltage to the values of CAT II.
Advice on noise immunity
All connections are protected against external
sources of interference. The installation loca-
tion should be chosen so that inductive or ca-
pacitive interference does not affect the device
or its connecting lines! Interference (e.g. from
switch-mode power supplies, motors, clocked
controllers or contactors) can be reduced by
means of appropriate cable routing and wiring.
Measures to be taken:
• Use only shielded cable and control lines.
Connect shield at both ends. The conductor
cross-section of the cables should be a mini-
mum of 0.14 mm .

• The shield connection to the equipotential
bonding should be as short as possible and
with a contact area as large as possible
(low-impedance).
• Only connect the shields to the control panel,
if the latter is also earthed.
• Install the device as far away as possible
from noise-containing cables.
• Avoid routing signal or control cables parallel
to power lines.

2.4 Cleaning and maintenance

The front side of the unit should only be
cleaned using a soft damp (water!) cloth.
Cleaning of the embedded rear side is not
planned and is the responsibility of the service
personnel or of the installer. In normal opera-
tion, this device is maintenance-free. Should
the device nevertheless not operate properly,
it must be sent back to the manufacturer or to
the supplier. Opening and repairing the device
by the user is not allowed and can adversely
affect the original protection level.

2.5 Start-up
The following points must be checked before
starting up the device:
1. Does the available supply voltage match the
supply voltage of the device?
2. Is the supply voltage connected to the good
terminals of the device?
3. For DC-powered devices, does the supply
voltage respect the polarity?
4. Is the device set and programmed correctly
(function; for counters, max. counting
frequency)?
2.6 Failure possibilities and causes
No display:
• No power supply
Keys cannot be operated:
• Key lock input is activated
Counter does not count:
• Wrong or reversed wiring of the counting
input
• Setting of an input signal not matching the
pulse generator
• Polarity (NPN/PNP) reversed
• Gate input is active
• No ground connection between the pulse
generator and the counter
• Maximum counting frequency exceeded
• Signal levels do not reach the switching
threshold of the counter
• Factor too small
Output signal is missing:
• Wrong output connection
• No ground connection to the following device
If, despite all, your device still does not oper-
ate, contact your local representative or call us
directly for technical support.
When sending your device back, please
attach a short description of the failure, of the
programming and of the connection diagram,
in order to allow us to reproduce a possibly
existing defect and to repair your device as
quickly as possible.
