IN GENERAL
The tank content display device LX-2 or LX-2-R is to be used for monitoring of tank levels in
pressureless liquid tanks. Aditional functions to liter displaying are e.g. temperature measuring,
data transmission or linking to facility management systems.
The LX-2-R type additionally provides two output relays, e.g. for controlling an alert unit, for
switching magnetic valve or dry protection of pump.
The displayed liter values are not to be used for billing purpose.
For the intended use and to abide the rules for warranty do strictly follow the Mounting and
Instructions, which have to be handed out to the owner.

P. 2 LX-2 / LX-2-R Mounting and Instructions Version: 07-2009
STRUCTURE
The LX-2 (-R) has an eight characters LCD display and a measuring input for a level probe.
The LX-2-R type additionally provides 2 programable relays, with opening and closing contacts.
The measuring probe can be mounted with a screw joint of R1 “ or R1½ “.
A reduction for 2“ is not included in scope of delivery.

Confirming to EN 50081-1 , EN 50082-1 and EN 61010-1 / A2
MOUNTING INSTRUCTIONS
Only qualifyed persons are allowed to install the measuring probe and to connect the display
device. Follow the regulation for each liquid, especially for the risk of water pollution and for
flammable liquids.
Condition for proper operation of measuring device is a professional installation. Follow the
technical rules for planning, construction and operation of the entire facility. Additionally follow the
rules for tank mounting and operation.
•Condition for proper operation is a pressureless storage tank. The tank must have proper
ventilation. Oil tanks and gasoline tanks must be equipped with a level limiter.
•The cable entry in the tank has to be made watertight and vapor tight by using PTFE sealing
tape.
•The measuring probe and display device are not safety devices. They do not replace the level
limiter of a tank.
•Installation of the display device in explosive zones is not permitted.
In that case ask for an EEx-probe with Zener barrier. The tank probe must be mounted inside
the tank with a cable protection pipe.
•The display device is connected to 230V AC. Operating is only permitted with closed box lid.
In case of inappropriate installation you lose any warranty.

P. 3 LX-2 / LX-2-R Mounting and Instructions Version: 07-2009
MOUNTING OF MEASURING PROBE
•In case of cellar steal tanks or subgrounded tanks use the included
screwing joint for mounting the measuring probe.
•If an old fuel gauge was used dismount it and use the tank screwing port.
•Subgrounded tanks normally provide an idle screwing port. In that case
dismount the dummy plug.
Mounting:
•In case of a heating oil tank switch off the oil burner and lock the suction
pipe if necessary.
•Clear the tank’s screwing port.
•Put the cable of the probe through the screwing joint. Put the measuring
probe into the tank.
•Mount the screwing joint with PTFE sealing tape.
•Sink the measuring probe down to the ground of the tank. Fix the cable
with the PG screwing. The measuring probe may optionally lay or stand on
the ground of the tank.
•Zero-point calibration is not required in normal case.
•If nessecary unlock the suction pipe, switch on the oil burner and check
the functions.
ELECTRIC INSTALLATION
Interconnection of measuring probe to display device
Probe supply: DC 15 – 24 V
Connection: Connect the 2-wire probe cable in the way:
Red(+) => clamp 1 , Black (-) => clamp 2.
Air capillary: The air capillary must have ventilation to atmosphere.
The end of the probe’s cable and the air capillary must
be protected against humidity.
Extension: The cable of the probe can be extended up to 100 m,
e.g. with NYM or YR or NYY.
Line diameter at least 2 x 0,4 mm².
In case of cable extension in a manhole or outdoors
it is recommended to use a waterproof clamp box with
special air pressure ventilation (accessories).
Shielding: Near by power current cables it is recommended to use
a shielded probe signal line. (Cable shielding has to be
grounded.)
Supply voltage:
Voltage: AC 230 V 50 Hz
Clamps: PE (protective conductor), N (neutral conductor),
L (phase).
Power line is not included in accessories.
Refer to last page.
The capillary in the
probe’s cable must
have ventilation.
The capillary filter
stays attached !
Refer to probe
instructions.

ERROR CODES
Message Meaning
Error E 1 Invalid input value.
Error E 2 Measuring value of the probe is too small !
- E002 at zero-point calibration: If current is less than 3,5 mA => Probe error.
- E002 at input step 4: Make sure the probe is plunged. Or current fluid level
is under the calibration minimum level.
Error E 3 Measuring value is too high for zero-point calibration.
- The probe must not be plunged ! A probe’s current higher than 4,5 mA indicates
a problem with the probe.
Error E 4 Setup is possible only if zero-point calibration is done.
Execute the zero-point calibration again (=> 9. Offset).
Error E 5 Height input is larger than tank height. (Wrong input.)
Error E 6 The measuring value is too small for reference. Make sure the probe is plunged.
Settled height is too large (or means the measuring value is too small for setting).
Execute the zero-point calibration again (=> 9. Offset).
If it does not work check the probe current (mA) !
Error E 7 The current measuring value is too small for the corresponding tank height or
the volume input value. Make sure the probe is plunged.
Error E 8 The current measuring value (or mA) is too high. Check electrical connection and
check the measuring range of the probe.
Switch the 230V supply voltage off and on. Check input steps 3 and 4.
Execute the zero-point calibration again. (=> 9. Offset).
Otherwise the measuring probe has to be checked.
Error E 9 The current value is 0 mA. The probe’s connection could be broken. Check the probe
connection (polarity) and extension. Measure the voltage at the probe (red to black).
Error E10 Calbration error. Switch off an on the 230V supply voltage and retry.
Otherwise the probe is working not properly.
Error E11 Warning – The liquid level in the tank is too low for an exact calibration.
(Press OK to continue anyway.)
Error E12 Yet no measurement data is received from the external tanks 2 ... 4.

FUNCTION CHECK
It is recommend to check if the displayed liters are correct after a complete fueling or once year.
Two practical options are: - Lift the probe and check the 0 Liter displaying
- Check the mm value displayed in Step ‘11. Set H’ (without trimming!)
