Overfill Prevention Sensor Testing Device
Type ME 5
Operating Instructions
Overfill prevention sensors have to
be tested regularly. The overfill
prevention sensor testing device
type ME 5 guarantees an optimal
and safe testing of sensors as per
TRbF 511.
Function:
The overfill prevention sensor
testing device (GWG) is heated up
by the intrinsically safe electric
current of the tester. The heating
time is measured, assessed and
shown on the LC-display.
The switching-off time is treated in
the same way. The QSS code is
recorded and also displayed (ME 5
with product recognition).
Overfill Prevention Sensor Testing Device
Type ME 5 with Coupling Type FP 903
and Charging Unit.
T
Since the overfill prevention sensor testing device
type ME 5 has its own instrinsically safe output circuit
it can be used for testing all overfill prevention sensor
testing devices certified as per TRbF (also the ones
applied in zone O). The ME 5 itself has to be operated
outside the ex-zone. The coupling type 903 required
for connecting the GWG is equipped with the
corresponding cable length.
For checking the product recognition the ME 5 has to
be equipped with a coupling type FP 903 and the
special software.
The ME 5 is equipped with Ni-MH accumulators.
These accumulators must be charged with the FAFNIR
charging unit only. Charging can only take place in a
non-operative condition. Empty accus will recharge
within appr. 14 hours.

LC-Display Meaning
Charge battery! The batteries are weak and should
be charged as soon as possible.
However, measurements can still
be made. You could only charge
the device when it is switched-off!
Please switch off! If this message appears, before a
measurement was made, the
batteries are too empty so that a
proper measurement is impossible.
Error!
plug defective
Incorrect product recognition;
clean plug and repeat
measurement with firmly attached
coupling.
GWG defective!
–interruption-
The GWG or the cable for the
connection fittings has an
interruption.
GWG defective!
–short circuit-
The GWG or the cable for the
connection fittings has a short
circuit.
GWG defective!
heating time too
short
The GWG is defective, the heating
time must be >5s.
GWG defective!
heating time too
long
The GWG is defective, the heating
time must be <180s. If there was
still liquid in the sensor tip, this can
prolong the heating time. Switch
off device and repeat measurement
after appr. 1 min.
GWG defective!
switching-off time
>2s
The switching-off time must be
<2s. The measurement can be
repeated since it is possible that
the immersion of the GWG and the
pushing of the <START> button
were not carried out
simultaneously. If the switching –
off time is >2s during the 2nd test,
too, the GWG is defective.
