1 Overview
Testing obligations in accordance with §§ 15 and 16 of the German Indus-
trial Safety Regulations (BetrSichV) and § 1 of the German Regulations on
Equipment Handling Substances Hazardous to Water (WasgefStAnlV). In
other countries, the corresponding national rules and regulations must be
observed.
When in operation, storage facilities for static tanks, filler points, petrol stations, airport refuelling equipment, and their components, e.g. overfill
prevention sensors, must be tested by an approved inspection agency prior
to commissioning, re-commissioning (after modifications subject to testing)
as well as repeatedly at specific testing intervals.
The system parts, e.g. overfill prevention sensors, must be tested by the operator or an authorised person as required by the manufacturer's operating
instructions at regular intervals.
The ME 6 … overfill prevention sensor testing device guarantees optimal and safe testing in accordance with prEN 13616-2 …
Three different types of these testing devices are available; they differ in the nature of
the application and the medium which is to be monitored:
• The ME 6 is used to test overfill prevention sensors without product coding.
• The ME 6 P is used to test overfill prevention sensors with product coding
in accordance with Quality Assurance systems (QSS).
• The ME 6 F is used to test overfill prevention sensors in LPG tanks.
In the following sections you will be guided by means of a detailed description
through the installation and commissioning of the ME 6 … overfill prevention sensor
testing device.
The ME 6 … overfill prevention sensor testing device may only be supplied
with power by 4 pcs NiMH rechargeable batteries (type AA 1.2 V, 2000 mAh).

Page 3/33 Design and construction
3.2 Function
The overfill prevention sensor is heated by the intrinsically safe electric current of the
ME 6 ... overfill prevention sensor testing device. The heating-up time needed is measured, assessed and presented on the screen. The switch-off time is treated in the same
way. The QSS coding is captured and also displayed (ME 6 P).
As the testing device has an intrinsically safe output circuit, it can be used for testing
all overfill prevention sensors approved by prEN 13616-2. The testing device itself must
be operated outside the Ex area. The type 903 socket coupler needed for the connection to the overfill prevention sensor is equipped with an appropriate length of cable.
The testing device must be equipped with a FAFNIR socket coupler type AS 903 for
checking the product identification.
The testing device is fitted with 4 pcs. NiMH rechargeable batteries. These batteries are
charged with the plug-in power supply via the USB socket or with the USB host of a
PC/laptop. They can only be charged when in USB mode. Depending on the nominal
capacity of the batteries, it takes about 10 hours to charge them. The batteries can be
freely exchanged.

4.2.1 Basic settings
After the first start or reset to the factory settings, the basic settings are to be set displayed automatically in sequence. The touch screen must then be calibrated. To do
this, each of the icons in the 4 corners must be touched until the next one is shown. A
point situated in the middle must be touched as final test.
Figure 6: Calibrating the touch screen
The calibration can fail if the points are incorrectly touched. In this case the basic settings are interrupted and the standard values are loaded. However, it is still possible to
configure the testing device at a later time by means of the graphical user interface.

4.3 Testing the Overfill Prevention Sensor
The operating mode Measurement must be set in order to be able to test overfill prevention sensors with the ME 6 ... overfill prevention sensor testing device. To set the
mode, push the toggle switch on the upper side of the testing device into the corresponding position.
Figure 10: Toggle switch in the measuring position
Testing the heating-up time of an overfill prevention sensor starts as soon as an overfill
prevention sensor is connected to the socket coupler and recognised by the system.
If the test fails to start, the resistance is outside the applicable figures; this
is caused, for example, by a short circuit or a cable breakage or by the toggle switch being in the wrong position.
The standard test includes the test of the heating-up time and optionally after successful completion the test of the switch-off time. This can be declined in a selection
dialogue. For ME 6 P the standard test includes the product recognition (QSS code).

Page 11/33 Testing the Overfill Prevention Sensor
The faults SHORT CIRCUIT and RESISTANCE TOO HIGH can occur in all tests, which
stop the test immediately. In the case of the RESISTANCE TOO HIGH fault, the testing
device has perhaps not been switched to the Measurement mode with the result that
the overfill prevention sensor is not connected to the heating circuit. Or a cable is
broken.

4.3.1 Heating-up time
The test starts automatically when the overfill prevention sensor is connected to the
socket coupler or if the field HEATING-UP TIME is selected in the main menu.
For ME 6 P the testing device attempts to read the QSS code. The code is displayed
and the actual measurement commences. The overfill prevention sensor is heated up
and the progress of the change in resistance is displayed graphically. If the target resistance value is not reached within 180 seconds, the measurement is aborted with a
fault. At the end of a successful test, a dialogue asks if the TEST FOR SWITCH-OFF TIME
is to be performed.

4.3.2 Switch-off time
The TEST FOR SWITCH-OFF TIME can be performed as an option immediately after a
successful TEST FOR HEATING-UP TIME. A corresponding dialogue is superimposed on
the display for this purpose. The test can also be selected manually by selecting the
field SWITCH-OFF TIME in the main menu.
The switch-off time is tested by heating the overfill prevention sensor. This is displayed
by the message HEAT. After a target temperature has been reached, the message
changes to READY and a 2-second count-down is displayed which ends with the command IMMERSE. The overfill prevention sensor must now be manually immersed in a
test liquid. The time needed for the overfill prevention sensor to fall to a pre-set value
is measured.

4.6 Power supply
The ME 6 ... overfill prevention sensor testing device is operated in measurement mode
by NiMH rechargeable batteries. The charge level is indicated in the status bar. If this is
low, the testing device must be recharged. This is done via the USB connection.
4.6.1 Changing the rechargeable batteries
The rechargeable batteries can be changed at any time. To do this, the cover of the
battery compartment must be opened with a Philips screwdriver and the rechargeable
batteries replaced by new ones. Battery alignment is shown by symbols in the battery
compartment. The rechargeable batteries need a nominal capacity of 2000 mAh. They
allow a number of approx. 150 complete measurements.
If it is likely that the instrument would not be used for a lengthy period, the
batteries should be removed and stored in the supplied case.
Only NiMH rechargeable batteries (type AA 1.2 V, 2000 mAh) may be used.
Power supply Page 22/33
Figure 28: Tog g le switch in Charge position
4.6.2 Regular charging of the rechargeable batteries necessary
When charging the batteries, the toggle switch must be set to Charge. The testing
device can then be connected to a computer or a USB plug-in power supply (5 V DC)
with the USB cable provided. The testing device immediately starts to charge the batteries. The current status is indicated in the upper status bar.
Depending on the capacity of the batteries used and their charge, charging the batteries from empty can take more than a day. If the testing device is used every day it is
recommended that the batteries are charged over the week-end.
When connecting to USB hubs with a passive supply, care must be taken
that without active supply these often limit the maximum current to 100 mA.
In this case it is not possible to charge the batteries.
To prevent a deep discharge of the batteries, they should be regularly
charged until they are full and at least every 20 days.

The overfill prevention sensor testing device acts as associated equipment and is not approved for use
in potentially explosive areas. The intrinsically safe sensor circuit can be brought into Zone 0 and is
suitable for all gas groups (IIA, IIB and IIC).
Because of the construction of the socket couplers the connection of the overfill prevention sensor must
be in Zone 1 or in a less hazardous area. The socket coupler type 903 and the CEE socket coupler are
classified as simple electrical equipment. The socket coupler type AS 903 is also marked and is suitable
for use in Zone 1 or a less hazardous area.
If the connection of the overfill prevention sensor is in potentially explosive areas with gases in temperature class T5 or T6*, the overfill prevention sensor testing device with product identification type ME 6 P
and the socket coupler type AS 903 may not be used.
The approval applies to equipment types
ME 6 OPS testing device without product identification (with socket coupler type 903)
ME 6 F OPS testing device for LPG overfill prevention sensors (with CEE socket coupler)
ME 6 P OPS testing device with product identification (with socket coupler type AS 903)
III.b … assembling and dismantling
The overfill prevention sensor testing device may only be assembled or dismantled when no overfill
prevention sensor is connected!
Only the battery compartment may be opened. Opening the case is not allowed as this could be damaged and the approval would therefore be void.
III.c … installation
No installation is necessary to operate the device.
III.d … adjustment
No safety-related arrangement or fittings are necessary to operate the device.
III.e … putting into service
The overfill prevention sensor testing device may only be connected to an overfill prevention sensor if
nothing is connected to the USB port.
The overfill prevention sensor may be connected and disconnected while the overfill prevention sensor
testing device is in operation.
* Overfill prevention sensor testing devices using the PTC resistor principle are certified to T3, maximum T4

III.f … maintenance (servicing and emergency repair)
The device is normally maintenance-free. In the event of a defect, the device must b e s end back to
FAFNIR or one of its agencies.
The overfill prevention sensor testing device may only be charged via a USB connection if no overfill
prevention sensor is connected.
If the batteries used are found to be defective they may be replaced by batteries of the same type.
