MOUNTING INSTRUCTIONS
Only qualified persons are allowed to install the measuring probe and to connect the display de-
vice. Follow the regulation for each liquid, especially for the risk of water pollution and for flam-
mable liquids.
Condition for proper operation of measuring device is a professional installation. Follow the tech-
nical rules for planning, construction and operation of the entire facility.
Additionally follow the rules of preventions of accidents by the government safety organizations
and the instructions of mounting and operation of the storage tanks too.
•
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 appropriately.
•
The measuring probe and display device are not securety devices. They do not replace the
level limiter of a tank.
•
Installation of the display device in explosive zones is not permitted.
Ask for an EEx-probe with Zener barrier. The tank level probe must be mounted inside the
tank with a cable protection pipe.
•
230V AC: The display device is connected to the power supply. Operating is only permitted
with closed box lid.
•
Type 230V AC :
The display device is connected to the power supply system and may normally only to be
used with box cover closed.
•
Type 12V / 24V DC:
As a special model this device type is supplied by a low voltage power supply of 24 V
(DC 20V-28V) or 12V (DC 11V-15V).
In case of inappropriate installation you lose any warranty.
MOUNTING OF LEVEL PROBE
•
In case of cellar steal tanks or subgrounded tanks use the included screw-
ing 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. Dismount the
dummy screwing.
•
If there is no other appropriate opportunity the measure probe can be
installed in the bearing pipe. We recommend the use of a 1“ T pipe collar
with a 1“ nipple for the head of the bearing pipe.
The cable of the measuring probe comes out of the T pipe collar on the
side. Occasional bearing for control parallel to the cable of the measuring
probe is still possible.
Mounting:
•
Switch off the oil burner and lock the suction pipe if necessary.
•
Clear the screwing port of the tank.
•
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 normally not required..
•
If necessary unlock the suction pipe, switch on the oil burner and check
the functions.
