l
No control cam available
l
Cable breakage
l
No voltage or voltage too
low
Check whether the control cam is present.
Check whether the sensor cable is broken.

Possible cause Sources of interference Corrective action
The sensor is interfered with or
influenced by external
magnetic or soft magnetic
materials (Fe).
Motors (coils) Increase the distance
between the sensor and the
mentioned sources of
interference (until the
sensor switches correctly).
Relays
Linear motors
Electrical welding
Magnetized components and
workpieces (workpieces made
of iron or similar materials)
Use finger attachments
made of aluminum.
Magnetized components and
tools (adapter plates made of
iron, iron screws or iron
hexagon socket keys, etc.)
Use components containing
aluminum. For example,
V4A screws are
recommended.
