IFM Electronic LR7022 Bedienungsanleitung Und Sicherheitshinweise Seite 30

Adaptation of the probe
The sensors are supplied with
probes in different lengths (L):
LR7022: L = 240 mm
LR7023: L = 450 mm
LR7024: L = 700 mm
The probes can be shortened to
adapt to different tank heights.
The minimum permissible probe
length Lmin is 150 mm.
Proceed as follows:
1. Mark the desired length (L).
2. Unscrew the probe from the unit.
3. Shorten the probe. Ensure that the probe length is not below the
minimum permissible length (15 cm / 6 inch).
4. Remove all burrs and sharp edges.
5. Screw the probe to the unit.
Recommended tightening torque: 4 Nm.
6. Set the new probe length during set-up (→ page 36, menu point:
LEnG).
Notes:
Probes are also available as accessories: E43203 (240 mm), E43204 (450 mm),
E43205 (700 mm).
Every LR70 type sensor can be combined with any of the indicated probes.
For ease of mounting and removal the probe can be rotated with respect to the
thread (process connection) without restriction. Even if rotated several times by
360° there is no risk of damage to the sensor.
