About this manual
This user manual explains how to install and configure the IK360 inclinometer with a Analog
(Voltage or Current) and RS232 interface by illustrations.

2 Introduction
2.1 IK360
IK360 inclinometers sense and measure the angle of tilt (Inclination/Slope/Elevation) of an
object with respect to the force of gravity. The angle is measured with the relative change in
electrical capacitance.
The basic principle behind this IK360 inclinometer is a Micro-Electro-Mechanical Systems
(MEMS) sensor cell, that is embedded to a fully molded ASIC. A simplified version of the sensor
consists of two electrodes, one is fixed, and the other is flexible (connected with spring
elements). When the inclinometer is parallel to the surface of measurement, a corresponding
capacitance is measured. If the sensor is tilted, the flexible electrode will change its position
relative to the fixed electrode. This results in a change of the capacitance between the two
electrodes, which is measured by the sensor cell. The change of the capacitance is converted to
a corresponding inclination value.
Absolute inclinometers identify all the points of a movement by means of an unambiguous
signal. Due to their capacity to give clear and exact values to all inclinations positions,
inclinometers have become one of the interesting alternatives to singleturn absolute (and
incremental) encoders and a link between the mechanical and control systems.
2.2 Analog interface
The analog interface is one of the most common and simplest of the interfaces. It is compatible
from simple multimeters to complex control systems and PLCs.
An analog signal is a continuous signal which is analogous i. e. comparable to another time
varying signal. In our case the variation of current or voltage signal from IK360 is analogous to
the variation of measured position.
In IK360, the position related output from MEMS based capacitance transducer measurement is
converted to its analogous current or voltage signals with suitable electronics.
An analog signal virtually has infinite resolution. In practice an analog signal is always subjected
to noise and a finite slew rate. Therefore, analog systems are subject to limitations in resolution
and bandwidth.
Noise and unwanted variation in signals can create losses upon transmission and
retransmission over long distances and for long time. Electrically, these losses can be reduced
by shielding, good connections and several cable types.
2.3 IK360 Analog
The IK360 Analog inclinometer is a simple, compact and a very low cost inclination
measurement device capable of measuring precise absolute position in single axis.
It is compatible to almost all the analog measurement devices and includes a RS232 digital
interface too. This RS232 interface can be used either to read the corressponding position
output or for configuring the IK360 according to the need of the application.

IK360-RS232 xDate: 23.01.2017 Page 5 of 22 Art.no. 86152 Mod. Status 10/17
Electrically, IK360 consists of a highly integrated circuit in SMD technology, temperature
compensation, active linearization and the only variation is the analog interface. Customized
scaling of analog output is also possible.
Electrically, like all other IK360 variants it consists of a highly integrated circuit in SMD
technology, temperature compensation, active linearization and the only variation is the analog
interface. Customized scaling of analog output is also possible.
It is protected against polarity inversion and over voltage peak protection. In addition to that, the
fully molded plastic housing provides an high resistance to shock/vibration and environmental
protection of up to IP69K, when used with appropriate connectors.
3 Installation
3.1 Pin assignment
The inclinometer is connected via a 8 pin round M12 connector (Standard M12, male connector

The function of the analog inputs depends on the configuration.

IK360-RS232 xDate: 23.01.2017 Page 6 of 22 Art.no. 86152 Mod. Status 10/17
Avoid mechanical load!
3.3 Mounting instructions
IK360 is a pre-calibrated device, which can be put into immediate operation, upon simple and
easy installation with a three point mount and setting of preset. Its compact design and
installation "anywhere" makes it versatile.
The IK360 inclinometer can be mounted in any number of fashions, depending on the situation.
The mounting surface must be plane and free of dust and grease. It is absolutely necessary,
that the IK360 inclinometer is connected to potential equalization in a workmanlike manner. For
mounting we recommend cheese head screws with metrical thread M4 or UNC bolts #6 for the
best possible and secure mounting. Use all the 3 screws for mounting, but restrict the tightening
torque in the range of 1.5 –2.5 Nm for the screws. The M12 connectors are to be perfectly
aligned and screwed till the end with a tightening torque in the range of 0.4 –0.6 Nm. Use all
the three screws for mounting and also note to use the same tightening torque for all the
screws. An appropriate and well secured counter connector is also an important constraint for
attaining the stated IP69K protection.
Prior to installation, please check for all connection and mounting instructions to be complied
with. Please also observe the general rules and regulations on low voltage technical devices, for
safety and sustainability of IK360 Inclinometers over long period of time.

4.2 Modes of Operation
Measurement Mode
Measurement mode of an IK360 is the free running operational output mode, in which the
position value is sent cyclically (according to the output transmission rate) using the RS232
interface.

IK360-RS232 xDate: 23.01.2017 Page 8 of 22 Art.no. 86152 Mod. Status 10/17
Configuration Mode
This mode is primarily used for modifying configurations and the settings of IK360 using RS232
Interface. In this mode, the position value is transmitted only upon request and is active until a
power cycle, software reset or the IK360 is switched to measurement mode. All settings saved
in this level are stored in the EEPROM and permanently available also after power cycle. There
are two additional configurations for the teach-in functionalities which can be configured in this
mode:
- Preset / Direction Mode
This is the default mode. In this mode, we can use an analog input for setting to zero position.
The default direction setting is clockwise. Analog input for inversing direction is not available
until setup to do so in RS232.
- Teach-In Mode (Scaling)
This is used for scaling of the analog output over a desired range, using RS232 or Analog
inputs.
4.3 Programmable parameters

5.4.4 Preset/Direction and Teach-in Mode
Preset/ Direction Mode (teach 0)
The Preset/Direction mode is the default mode in which the IK360 operates. In this mode the
user can set the origin of measurement (0° Reference Angle) at the current point and can also
change the direction of measurement. The changes done in the RS232 mode also gets
reflected in the analog output.
Preset: Set Origin at current Position (setorg)
The "setorg" command is used to set the origin (0° reference) to the current position. The
analog output is also reset to read either 4 mA or 0 V according to the analog interface in use.
Reset the origin to factory default (clrorg)
The origin position can be reset to factory default position by using this command. The analog
output is also reset to show the factory default output.
Invert the direction of measurement (compl)
The "compl" function is used to specify the direction of measurement to either Standard or
Inverted according to the user’s requirement. The default setting is clockwise (IK360). The
analog input SET2 can be used for this function only if compl is set to "2".

5.4.5 Teach-In mode (teach 1)
This is the mode used for scaling the IK360 output as per the users’ requirement. The user can
set the range of measurement and the IK360 analog output is scaled accordingly. The range of
measurement is defined to lie within the origin and maximum angle positions, which then
corresponds to the analog output scaling. The sequence SET1 and then SET2 must be
observed!
Important: The maximum angle set in this mode will not affect the RS232 position output. This
scaling only affects the analog output.
The execution of this "setmax" is immediately reflected in the analog output. The analog output
at the setpoint is either 20 mA (IK360+I) or 10 V (IK360+U) once the execution is complete.
The execution of "clrmax" function clears the previous scaling done by the user and resets the
analog output to the factory default values.
Important Points for programming:
The use of preset in the digital interface will affect the analog output too. When using both
the interfaces simultaneously take appropriate pre-cautions.
Be carful not to mix up the commands für the RS232 teach-in modes. If in doubt, use the
restore command and reconfigure sensor.
The configurations/ scaling set in teach 1 mode is not reflected in teach 0 mode.
Errors
When parameters are defined beyond the programmable limits then the IK360 gives an error
"E" output.
5.4.6 Analog Inputs (SET1 and SET2)
The inclination sensors are designed to include 3 features through analog inputs SET1 and
SET2.
Preset of origin –0° Reference for measurement
Inversion of measurement direction
Output scaling according to the set measurement range

IK360-RS232 xDate: 23.01.2017 Page 16 of 22 Art.no. 86152 Mod. Status 10/17
The IK360 has two configuration modes for the abov functionalities:
Preset/Direction mode: Configuration for setting the new origin and direction of
measurement
Teach-In Mode: Scaling of output according to user's measurement range.
The modes can be changed using the RS232 interface. By default, the IK360 sensor is in the
Preset/Direction Mode, with the option of inversing direction with an analog input only if
configured to do so in RS232.
The IK360 has two analog inputs, SET1 and SET2 which can be used to configure in the IK360.
To trigger/activate these functionalities (e. g. a Preset):
The user must apply a positive voltage (5 V –30 V, Rin > 110 KΩ) on the SET1/SET2 input.
When a high edge is recognized a timer starts.
The voltage must be held at least 100 ms if the voltage has been held less than 100 ms, the
timer will be reset. The voltage must be released for postion to be locked.
Set a new range: Example 0 … 180°
1. Build up a RS232 communication between IK360 and PC. When you power-up the sensor
IK360 it sends the boot-up messange, then it sends the position values continuously.
2. Enter the Programming mode by sending <CR>.
3. Get into the Teach-In Mode with the command "teach <SP>1<CR>".
4. First define new 0° position and second define 180° position.
5. Leave the teach-in mode by using the command "exit <CR>" via RS232 communication.

5.4.7 Preset
The IK360 has to be set to the Preset/Direction mode (teach 0) through the RS232 interface to
implement his function. Preset/Direction mode is the default factory setting.
To set the preset, apply a high signal (5 V –30 V) pulse to SET1 input and lock the position.
Once the position is locked the IK360 resets the current position to the origin position and hence
changes the analog output accordingly to either 4 mA or 0 V.
Important:
The origin set by the analog input SET1 can be revoked to the factory default setting by
using clrorg function in the RS232 interface.
5.4.8 Invert Direction
The IK360 has to first be set to the Preset/Direction mode (teach 0) ant the "compl" function has
to be set to parameter 2 (compl 2) through the RS232 interface to implement this function.
SET2
Direction of Measurement
High (5 V –30 V)
Counter-Clockwise / Inverted
Low (No Connection) or GND
Clockwise / Standard
To set the inversion of direction, apply a continuous high signal (5 V –30 V) to SET2 input. As
long as the applied signal on SET2 is greater than 5 V, the direction of measurement is always
inverted.
5.4.9 Scaling of Output
The IK360 has to first be set to the Teach-In mode (teach 1) through the RS232 interface to
implement this function.
Scaling of output is done based on a user defined angular measurement range. The range is
defined by the two set points created by analog teach-in inputs SET1 and SET2. The analog
output is scaled to give a full measurement output (4 –20 mA / 0 –10 V) over the defined range
of measurement.
It is recommended to do scaling as a sequence of steps as detailed below:
Set the IK360 to Teach-In Mode (teach1)
Give a high signal pulse to SET1 at the measurement range to lock the position. Once
position is locked (indicated by origin position output (4 mA or 0 V) output in the range of
measurement set between the locked positions of SET1 and SET2.
If the scaling was done correctly the IK360 should giva a (4 mA –20 mA) or (0 V –10 V) output
in the range of measurement set between the locked positions of SET1 and SET2.
The scaling can be done also counter-clockwise. The output is scaled according to the
direction of the sensor motion for the SET inputs. Upon scaling, the RS232 angular output
sets preset automatically at SET1 position.

6 Analog Interface
The output signal from the IK360 analog interface can be directly connected to devices for
immediate processing. The calibration of the signals can be easily done, since the signals are
linear.
6.1 Output Types
6.1.1 IK360 - Voltage
Connect the corresponding (voltage analog output pin 5) open end of the connection cable to
the measurement system.
IK360 with voltage output
Calculation of angle from IK360 voltage:
Position angle (in °) = (10 V) / (0.02777 Volts per °)
For example:
1. Uout = 1.6662 V
Position Angle = (1.6662 V) / (0.02777 V per °) = 60°
2. Uout = 5.554 V
Position Angle = (5.554 V) / (0.02777 V per °) = 200°

6.1.2 IK360–Current
Connect the corresponding (current analog output Pin 5) open end of the connection cable to
the measurement system. IK360 output current, Iout can be directly measured or indirectly
measured as voltage, using a shunt resistor (Note: RLoad ≤270 Ω).
Direct Current Measurement
Indirect Current Measurement
Calculation of angle from IK360 (1 axis) current:
Position angle (in °) = (Iout - 4 mA) / (0.0444 mA per °)
For example:
1. Iout =8.31 mA
Position Angle = (8.31 mA - 4 mA) / (0.0444 mA per °) = 97.07°
2. Iout = 11.6 mA
Position Angle = (11.6 mA - 4 mA) / (0.0444 mA per °) = 171.17°

Calculation of angle from IK360 (2 axis) current:
Position angle (in °) = (Iout - 12 mA) / (0.1 mA per °)
1. Iout =8.31 mA
Position Angle = (8.31 mA –12 mA) / (0.1 mA per °) = -36.9°
2. Iout = 11.6 mA
Position Angle = (11.6 mA –12 mA) / (0.1 mA per °) = -4°
