2.6.6 Trouble shooting
Below are some typical errors which may occur during installation and operation:

The value shown on the display does not correspond to the actual value because the
parameter setting for the counting resolution is set improperly.

Magnetic strip incorrectly mounted (active surface must be mounted towards the sensor).

To protect the magnetic tape the supplied cover tape was not used. Must always be non-
magnetic.

Sensor incorrectly connected. Check connection

Tolerance for the gap between magnetic sensor and magnetic strip not observed over the
total traveldistance (

Img.2-6:).

Cable squeezed / interrupted / cut by sharp edges.

Sensor's active side not mounted towards the magnetic strip (


NOTE !
The following statements describe the procedure for attachment of OPTIMUM ML-type absolute
measuring glass scales.
Please follow the installation instructions and requirements accompanying the given component
when installing incrementally measuring magnetic measurement systems from OPTIMUM, or
for measurement systems from third-party manufacturers.
Depending on the attachment possibilities on your machine, mounting and connection to the
machine axes may differ.
The following drawing should aid in selection of the required measuring gib lengths and
description of the mounting situation.
ATTENTION!
Only use path-measuring systems recommended by OPTIMUM. When assembling the
path-measuring systems imperatively follow the instructions of the manufacturer.
NOTE !
The path-measuring system and its add-on pieces can cover important components on the
machine tool (e.g. lubricating nipples).
Before mounting the path-measuring systems, please take note of any such limitations in func-
tions and make arrangements accordingly.
