5. Commissioning
Danger of death from explosion,
airborne parts, leaking fluid,
electric shock
-
Explosion hazard if the operating
voltage is too high (max. 28 V
DC
DANGER
-
Operate the device only within the
specification! (according to data sheet
and EU-type examination certificate)
The device has been installed properly.
The device does not have any visible defect.
6. Maintenance
Danger of death from airborne parts,
leaking fluids, electric shock
-
Always service the device in a
depressurized and de-energized
DANGER
condition!
Danger of injury from aggressive fluids
or pollutants
-
Depending on the measured medium,
this may constitute a danger to the
operator.
WARNING
-
Wear suitable protective clothing
e.g. gloves, safety goggles.
If necessary, clean the housing of the device using a
moist cloth and a non-aggressive cleaning solution.
During the cleaning processes, note the compatibility of the
cleaning media used in combination with the media-wetted
materials of the pressure measuring devices. Permissible
concentrations and temperatures must be observed.
Verification/validation by the user is essential.
Deposits or contamination may occur on the diaphragm/
pressure port in case of certain media. Depending on kind and
quality of the process, suitable cyclical maintenance intervals
must be specified by the operator. As part of this, regular checks
must be carried out regarding corrosion, damage of
diaphragm/seal(s) and signal shift. A periodical replacement of
the seal(s) may be necessary.
7. Troubleshooting
Danger of death from airborne parts,
leaking fluids, electric shock
-
If malfunctions cannot be resolved, put
the device out of service (proceed
DANGER
according to chapter 8 up to 10)
Danger of death from explosion
-
As a matter of principle, work on
energized parts, except for intrinsically
safe circuits, is prohibited while there is
DANGER
an explosion hazard.
In case of malfunction, it must be checked whether the device
has been correctly installed mechanically and electrically. Use
the following table to analyse the cause and resolve the
malfunction, if possible.
Fault: no output signal
Possible cause
Fault detection / remedy
Connected incorrectly
Checking of connections
Checking of all line
Conductor/wire breakage
connections.
Checking of ammeter
Defective measuring device
(miniature fuse) or of analogue
(signal input)
input of your signal processing
unit
Fault: analogue output signal too low
Possible cause
Fault detection / remedy
Checking of load resistance
Load resistance too high
(value)
Checking of power supply
Supply voltage too low

Checking of the power supply
Defective energy supply
and the supply voltage being
applied to the device
Fault: slight shift of the output signal
Possible cause
Fault detection / remedy
Diaphragm of senor is
Checking of diaphragm; if
severely contaminated,
necessary, send the device to
calcified or crusted
AFRISO for cleaning
Fault: large shift of the output signal
Possible cause
Fault detection / remedy
Diaphragm of sensor is
Checking of diaphragm; when
damaged (caused by
damaged, send the device to
overpressure or mechanically)
AFRISO for repair
Fault: wrong or no output signal
Possible cause
Fault detection / remedy
Checking of cable; pitting
corrosion on the stainless-steel
Cable damaged mechanically,
housing as a result of damage
thermally or chemically
on cable; when damaged, send
the device to AFRISO for repair
8. Removal from service
Danger of death from airborne parts,
leaking fluids, electric shock
-
Disassemble the device in a
depressurized and de-energized
DANGER
condition!
Danger of injury from aggressive
media or pollutants
- Depending on the measured medium,
this may constitute a danger to the
operator.
WARNING
- Wear suitable protective clothing
e.g. gloves, goggles.
NOTE -
After dismounting, mechanical connections must be
fitted with protective caps.

9.1 Recalibration
During the life-time of a transmitter, the value of offset and span
may shift. As a consequence, a deviating signal value in
reference to the nominal pressure range starting point or end
point may be transmitted. If one of these two phenomena occurs
after prolonged use, a recalibration is recommended to ensure
furthermore high accuracy.
9.2 Return
Danger of injury from aggressive
media or pollutants
- Depending on the measured medium,
this may constitute a danger to the
operator.
WARNING
- Wear suitable protective clothing
e.g. gloves, goggles.
Before every return of your device, whether for recalibration,
decalcification, modifications or repair, it has to be cleaned
carefully and packed shatter-proofed. You have to enclose a
notice of return with detailed defect description when sending
the device. If your device came in contact with harmful
substances, a declaration of decontamination is additionally
required. Appropriate forms can be downloaded from our
homepage.
Download these by accessing www.afriso.com or request them:
[email protected] | phone: +49 7135 102-211
In case of doubt regarding the fluid used, devices without a
declaration of decontamination will only be examined after
receipt of an appropriate declaration!

10. Disposal
Danger of injury from aggressive
media or pollutants
- Depending on the measured medium,
this may constitute a danger to the
operator.
WARNING
- Wear suitable protective clothing
e.g. gloves, goggles.
The device must be disposed of according to the
European Directive 2012/19/EU (waste electrical
and electronic equipment). Waste equipment must
not be disposed of in household waste!
NOTE -
Dispose of the device properly!
11. Warranty terms
The warranty terms are subject to the legal warranty period of 24
months, valid from the date of delivery. If the device is used
improperly, modified or damaged, we will rule out any warranty
claim. A damaged diaphragm will not be accepted as a warranty
case. Likewise, there shall be no entitlement to services or parts
provided under warranty if the defects have arisen due to normal
wear and tear.
