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.
