Air Gap Between Measuring Surface And Target Wheel; Electrostatic Discharge; Cable Gland; Cable Duct - Lenord+Bauer GEL 2477 Betriebsanleitung

Lenord + Bauer
uring surface could 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.
3.3.3

Air gap between measuring surface and target wheel

If the air gap, which means the clearance between the measuring surface and the target
wheel is too great, the measurement signal can be lost.
If the air gap is too small, the measuring surface may come in contact with the target
wheel if this runs out of round.
 Ensure that the air gap between the measuring surface and the target wheel is
within the permissible range (see table
3.3.4

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:
3.3.5

Cable gland

The cable gland protects the sensor from moisture and dust. Opening this connection
may result in malfunctioning of the measuring electronics.
Do not unscrew the cable gland.
3.3.6

Cable duct

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

3.3.7

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.
