Air Gap Between Measuring Surface And Target Wheel; Electrostatic Discharge; Screwed Cable Gland; Cable Duct - Lenord+Bauer GEL 2470 Betriebsanleitung

3 Notes on avoiding ...
surface can be damaged if it touches the target wheel or as a result of other mechanical
impact.
Ensure that the measuring surface does not come in contact with other
objects.
3.4.3

Air gap between measuring surface and target wheel

If the air gap, i.e. the spacing between the measuring surface and the target wheel is
too great, the measurement signal can be lost.
If the spacing is too small, the measuring surface may come in contact with the target
wheel if this runs out of round.
 Make sure that the air gap between the measuring surface and the target wheel is
within the permissible range (see table
3.4.4

Electrostatic discharge

Electrostatic discharge can destroy the electronic components.
Only touch the connector pins and connecting wires when wearing a suit-
able grounding device, such as an ESD wristband:
3.4.5

Screwed cable gland

The screwed cable gland protects the sensor from moisture and dust. Loosening can
damage the measuring electronics.
 Do not unscrew the screwed cable gland.
3.4.6

Cable duct

The connection cable can be damaged if it is bent too sharply.
Please note the minimum bending radius (see

3.4.7

Contamination

The accumulation of ferromagnetic particles between the measuring surface and the
teeth of the measuring scale may mean that the speed sensor cannot clearly read the
change from tooth to gap.
 Check the speed sensor regularly for contamination and clean it if necessary
