 If applicable, switch the oil burner off and lock the take-off pipe of the
tank.
 Clear the opening at the tank.
 Push the screw fitting, if applicable with reduction bush(es), over the
probe cable and insert the probe into the tank.
 Seal the screw fitting smell-tight (e.g. with PTFE tape) and screw it into
the tank cover.
 Lower the probe into the tank until the probe head touches the tank floor
(you will feel it via the cable). Then, screw down the cable gland to fix the
cable. Optionally, the probe can also be fixed in a lying position on the
tank floor.
 Usually, it is not necessary to perform a probe zero adjustment.
 Re-open the take-off line of the tank and reactivate the oil burner if
applicable. Check the function of the oil burner.
Electrical Installation
Connection line between indicator and probe:
Voltage: Probe element 20 V DC
Connection: Probe connection cable to terminals 1 (red) and 2 (black)
(see figure below)
Air capillaries: The cable must be installed in such a way that pressure
equalization with the ambient air is ensured but no moisture
can penetrate into the cable end.
Extensions: The probe cable can be extended by max. 200 m - e.g. with
cable type NYM or YR (moisture-proof) or NYY (ground) and
with min. cable cross-section 2 x 0.4 mm
2
.
For cable extension in the dome or outdoors, a
waterproof connection box with special pressure
equalization filter must be used (accessory).
Shield: If the probe cable (or extension) runs close to power lines, a
shielded signal line should be used (connect shield to
PE terminal).
Connection of supply voltage:
Voltage: 230 V AC 50 Hz
Connection: Terminals PE, N + L to the indicator (cable is not part of the
delivery)
