2 Appropriate use
2.1 Field of application
The tilt sensor is designed for measuring the inclination (angle from a horizontal
line) in different devices, machines etc.
The ambient conditions must be checked by the user before using the tilt sensor.
2.2 Norms and guidelines
The tilt sensor complies with the following European guideline:
2004/108/EC (EMC guideline)
2.3 Safety/Dangers
- Only operate the tilt sensor in a completely closed and undamaged housing.
- Only replace components with original spare parts which are approved for the
defined application.
- Operate the tilt sensors only in accordance with their intended use. Failure to
comply with these conditions will invalidate any warranty claims or any liability
on the part of the manufacturer.
- Ensure that all safety requirements applying to the individual machines are
observed.
- Ensure that the international and national regulations are observed.

3 Function
3.1 Mode of operation
The tilt sensors of series N3/N4 employ the capacitive measuring method.
The sensors supply a linearised output voltage or an output current depending on
the inclination (see Electrical data).
In addition, different switching points can be defined which activate one or
several relays.
The configuration of the sensors is defined in the type denomination.
3.2 Neutral position adjustment
(optional with IR remote control)
All tilt sensors are preprogrammed with a neutral position (see the fold-out page).
The user can adjust the neutral position using the infrared remote control
"IR-NGS01" (not included in the scope of delivery), if required.
During this adjustment, the current inclination angle is defined as the neutral
position.
NOTE The neutral position can only be adjusted within a minute after the
operating voltage has been applied.
Defining the neutral position:
- Shortly press the button on the IR remote control. The remote control is
activated. LED 1 lights up briefly to indicate readiness for operation.
- Press the button for longer than 2 seconds. A data signal is transmitted to the
tilt sensor. LED 1 on the IR remote control flashes rapidly to indicate that the
transmission is in progress.
If the button is not pressed within 8 seconds, the remote control is deactivated
and will have to be reactivated by pressing the button again.
LED 2 on the tilt sensor flashes briefly three times to confirm the correct receipt
of the data signal.

Point the IR remote control towards the sensor as shown in the figure.
4 Installation
- Ensure that the tilt sensor is only installed by specially-trained authorised
personnel.
- Install the tilt sensor on a level surface (mechanically unstressed).
- The tilt sensor must not be modified.
- Connect tilt sensor, see Technical data.

5 Putting into operation
- Ensure that the tilt sensor is only put into operation by specially-trained
authorised personnel.
- Ensure that the electrical data is adhered to.
- Observe the operating instructions and notes provided by the manufacturer
of the device.
- Apply operating voltage and check the proper functioning of the tilt sensor
according to application.
6 Maintenance
6.1 Measures
The tilt sensor is maintenance-free.
6.2 Disposal
Dispose of used parts and unwanted packaging in accordance with the
regulations of the country in which the device is installed.
