Operating Instructions ACCOMOS Page 9

Attention!

The surface for sensor installation must be flat
and free from dust and grease.

The magnetic sensor fixture has a strong
magnetic force! Improper handling may result
in skin or fingers becoming crushed.

The strong magnetic field of the sensor fixture
can influence the function of pacemakers and
defibrillators:

- Pacemakers may switch to test mode

and cause discomfort

- Defibrillators may fail completely

If you are wearing such devices, maintain a
sufficient distance from the magnetic fixture.

Keep the magnetic fixture away from any
devices and objects that could be damaged by
strong magnetic fields.

2 Installation instructions

2.1 Mechanical installation

- To avoid injury by crushing skin and fingers, we

recommend wearing protective gloves during
installation and removal

- During installation and removal, it is necessary to

ensure adequate lighting and a stable base at the
workplace

Operating Instructions ACCOMOS Page 10

Installation:

- Loosen the M8x16 INBUS screw in the center of

the sensor and replace it with the M8x30 INBUS
screw (Illustration 1)

- Use the M8x30 INBUS screw to press the sensor

off the sensor protective plate (Illustration 2)

- Place the sensor on a flat and clean magnetic base

(oil and dirt must be removed beforehand if
necessary)

- Remove the M8x30 INBUS screw again so that the

sensor sits flat on the installation base (protect the
screw with the sensor protective plate for
transportation purposes -
Illustration 3)

- To protect the screw opening, insert the M8x16

INBUS screw again and tighten it (Illustration 4)

- Connect the supplied ground cable to the next

ground point, making the distance as short as
possible (Illustration 5)

- Check that the sensor is correctly mounted

- Connect the sensor to the power supply (and data

bus) using the M8 plug-in connector (Illustration 6)

Attention!

Do not reuse sensors with faulty seals on
the magnetic mounting plate. Otherwise,
there is a possibility of cuts due to
splintering of magnetic parts.

Removal:

- Disconnect the sensor from the power supply (M8

plug-in connector) and the ground cable

- Remove the M8x16 INBUS screw from the center

of the sensor and replace it with the M8x30 INBUS
screw

- Use the M8x30 INBUS screw to press the sensor

off the surface

- Place the sensor on the sensor protective plate

- Remove the M8x30 INBUS screw again so that the

sensor sits flat on the sensor protective plate

- To protect the screw opening, insert the M8x16

INBUS screw again and tighten it

-

For safety reasons, never transport a sensor
without a sensor protective plate!

Typical installation points can be found in DIN ISO 10816-1
/ DIN ISO 10816-6.
