3Product Features
The robust constructed INAX2 inclinometer is able to realize a high precision and reliable inclination angle
measurement. Inclinations within a range of ± 180° (Z axis) and ± 90° (X / Y axes) can be measured.
With the optionally available protection class of IP67, the sensor is also suited for rough environments. Further
impressive features of the INAX2 system are its easy installation and high shock resistance.
3.1 Functional principle
With inclinometer measurements, a seismic mass is placed between two capacitor plates. An electrostatic feed-
back defines the slope change of the sensor. This feedback is converted by an integrated circuit into serial or
analog interface signals (see below).
Diverse output interfaces are available:
CANopen - extended DS406 (6.1)
RS422 (7.2)
Analog 0 … 10 V (7.3)
Analog 4 … 20 mA (7.3)
The respective order code can be found in the type designation (9).

8Disturbances, Maintenance, Cleaning
This chapter describes possible causes for disturbances and measures for their removal. In case of increased disturbances, please follow the
measures for fault clearance in chapter 8.1. In case of disturbances that cannot be eliminated by following the advice and the fault clear-
ance measures given here, please contact the manufacturer (see second page).
8.1 Fault Clearance
CAUTION!
The device, the connection line and the signal cable must not be installed next to sources of interference that emit
strong inductive or capacitive interference or strong electrostatic fields.
External perturbations can be avoided thorough suitable cable routing.
The screen of the signal output cable should only be connected to the following circuit on one side. The screens
should not be grounded on both sides. Signal cables always have to be routed separately from the load power line.
A safety distance of at least 0.5 m has to be kept from inductive and capacitive sources of interference such as con-
tactors, relays, motors, switching power supplies, clocked controllers etc.!
If interferences occur in spite of all the items stated above being observed, please proceed as follows:
1. Installation of RC-circuits via contactor coils of AC-contactors (e.g. 0,1 µF / 100 Ω)
2. Installation of recovery diodes via DC-inductors
3. Installation of RC-circuits via the different motor phases (in the terminal box of the motor)
4. Do not connect protective earth and ground
5. Connect a mains filter ahead of the external power pack
8.2 Re-start after Fault Clearance
After the fault clearance:
1. Reset the emergency stop mechanism if necessary
2. Reset the error report at the super-ordinate system if necessary.
3. Ensure that there are no persons in the danger area.
4. Follow the instructions from chapter 5.
WARNING!
Danger of injury through non-conventional fault clearance!
Non-conventional fault clearance can lead to severe injuries and damage of property.
Therefore:
Any work to clear the faults may only be performed by sufficiently qualified staff
Arrange enough space before starting the works
Make sure that the mounting area is clean and tidy. Loose components and tools are sources of accidents.
If components need to be replaced:
Pay attention to a correct installation of the spare parts.
Reinstall all the fixing elements properly
Before turning on the device, ensure that all covers and safety equipment is installed correctly and functions
properly
