5Inclination sensor explained
An inclinometer measures the angle(s) of the device with respect to earth gravity, using earth gravity vector as
external reference. The inclinometer involved is based on an accelerometer. The acceleration values are used to
calculate the angle(s). The device takes both the static component (100%) and the dynamic component (partial,
depending on frequency and bandwidth-setting) into account. The device will periodically send a CAN message
on the CAN-bus containing the angle(s) in degrees.
6Safety function
The safety function of the inclinometer sensor is to generate angle information based on acceleration values
(caused by gravitation) measured by a MEMS acceleration sensor chip. Based on this angle information the safety
controller of the application can switch the machine to safe-mode in order to prevent for a dangerous situation.
Example: a crane having a maximum tilt angle of the chassis. If the tilt angle of the chassis exceeds a certain
critical value, the crane will fall over. To prevent for this an inclinometer can be mounted on the chassis,
measuring the X- and Y tilt of the chassis. The safety controller of the application should monitor the X- and Y tilt
angles and should switch the crane to safe-mode as soon as a certain tilt angle for X and/or Y exceeds the limits
for the application. This will significantly reduce the risk of a dangerous situation to happen.
7Hardware setup

8Signal processing
The Safety sensor transmits SRDO messages. These message must be used to check the data and timing. In this
SRDO message the angle information is available in normal and in inverse format. Customer should compare
these messages in order to check the sensor output is safe. It is also possible to send the data via the TPDO
message according to CiA410 but in this case the sensor should be treated as a non-safety sensor. An output
filter is available for a stable signal. To compensate for mounting tolerances a pre-set/zero adjustment option is
available. When pre-set/zero values are changed a CRC must be calculated off-line (CRC calculate tool available)
and written to the sensor. The settings of the SRDO messages are also protected with a CRC code. When these
are changed also new CRC code must be determined. When the sensor detects a failure an emergency message
is generated and a safe state is activated. In the safe state no communication is possible (No SRDO, TPDO and
Heartbeat).
8.1 Sample rate:
The internal g-sensor chip is sampled every 10ms. Each sample of the element consists of 16 samples for each
axis. Resulting in sample rate of 1600 Hz. These samples are input for a 32 tabs FIR input low pass filter. Each
10ms new data is available for the CAN bus.
8.2 Averaging:
The FIR filtered values are averaged during the TPDO1 cycle time set by the customer. A longer TPDO cycle time
results is a smaller bandwidth and therefore a more stable output signal (less noise), but also more phase delay.
e.g. if Event time TPDO1 is 10 ms (fastest time) à a filtered value of 16 samples is available.
e.g. if Event time TPDO1 is 100 ms à an average value of 10*16 samples is available.
8.3 Output filter:
The output of the sensor can be extra filtered by a 1st order low-pass filter. Default this output filter is disabled.
Via the CAN object dictionary (index 300Eh) this filter can be controlled, by setting the time-constant in ms, with
a maximum of the redundancy compare time (set by index 4006h sub-index 02h) .
The time constant is defined as the time in which the output changes to 70% of the step after a step response.
The -3dB frequency can be calculated by the formula f = 1 / (2*pi*time-constant). This -3dB frequency is
independent of a change in TPDO1 event time and the SRDO refresh time. But when the output filter time-
constant is set < min. [TPDO1 event time, the SRDO refresh time], the output filter is disabled. With the factory
default, the filter time-constant can be set within 50ms –2000ms, other value will disable the filter.

Inclination Safety Sensor
(Type D) V2.0
8.4 Peak Suppression Filter:
Two Peak Suppression Filters (PSF) are implemented to reduce unwanted disturbances in the inclination
measurement caused by acceleration peaks.
Filter principle: as inclination normally changes relative slow, a sudden peak in the inclination signal indicates an
acceleration peak instead of a real inclination angle change. In this case, the filter can make the sensor ignore
this peak for a certain time.
PSF in the redundancy compare chain (object 4007h):
The redundancy compare chain checks the difference between the two redundant MEMS chips. The filter helps
to prevent for false safety alarms.
PSF in the inclination output chain (object 4008h):
The filter in the output chain makes the inclination output more stable and more realistic
PSF can be adjusted with 2 parameters:
•Angle (°): This parameter sets the threshold for the peak. Only peaks above this threshold will be
filtered. Setting this angle parameter to 0° will disable the PSF
•Time (ms): After the peak suppression filter becomes active, it will hold the inclination signal for a
certain period of time, set by this parameter.
Default values for Object 4007h: on, 3°, 40ms
Default values for Object 4008h: on, 9°, 50ms
8.5 Pre-set/zero adjustment:
To eliminate mechanical offsets a pre-set/ zero value can be added. This can be done with the pre-set/zero
adjustment method, so introducing a permanent offset on the output of the sensor (centre point = middle of
measuring range). The current position will be regarded as the new pre-set/zero position. This can be done
limited to 100.000x. (The value is written in EEPROM. The write actions for EEPROM is limited to 100.000x)
Via CAN object 300Fh (see sensor specific part) the centering/zeroing can be done for each axis separate or for
both axis at the same time. Status information of the result is available from the same object 300Fh
Since the offset has direct influence on the output angle, the pre-set/zero value is protected with a CRC code.
This CRC code must be set via object 63FFh. When the CRC code is written it must be validated with object 63FE
sub id 0 writing data A5h.
The polynomial of the CRC code is:

For CRC calculation a PC tool is developed and can be found on the DIS web site www.dis-sensors.com
We have implemented two different CRC-calculations. Please check your firmware version number first, and then
select the right Firmware version when using the PC-tool.
A CRC code is also oblige for SRDO1 messages. For detailed information about generating see EN 50325-5. This
CRC code can also be calculated with the same PC tool.

8.6 Accelerator element tolerance
The sensor consists of two accelerator elements. The acceleration values of these elements are converted to
angles. These angles are compared and a safe state is set when the elements differ too much. To prevent for
false alarms, a tolerance can be configured. The tolerance consists of allowing an angle deviation during a certain
time.
These values are adjustable via object 4006h sub- index 01h and 02h. The default values are 300d and 200d ( 3°
during 2000 ms). The actual values used by the customer should fit the application involved. Before using this
sensor and with the settings chosen the customer should evaluate risks in order to check whether the chosen
settings satisfies his safety requirements. Manufacturer is not responsible for any damage caused by these
customer-setting, even when the manufacturer defaults are used.
Definitions for the Redundancy error:
‘Redundancy Compare time’ (user programmable, default 2000ms)
‘Redundancy Compare angle’ (user programmable, default 3°)
8.7 Output invalid
A vertical device measures the angle relative to the gravity. When a device is tilted towards the horizontal plane
for more than 45°, the angle can’t be accurately measure because the gravitation vectors become shorter. In this
case the output is set to 200°. This value indicates that the output is invalid.
For horizontal devices the same principle is valid. When the longitudinal axis is greater than 45 degree the output
for lateral axis is set to 200°. When the lateral axis is greater than 45° the longitudinal is set to 200°. The output is
also invalid when the range limits are reached. Example when angle is 32° for a ±30 device the output is limit to
±30°. For a ±90 device the angle is limited to ±90°.
8.8 Writing objects
When writing an object it can have a major influence on the output. To prevent unauthorized changes most write
action can only be executed when the device is in pre-operational state. According to EN 50325-5
8.9 Changing SRDO1 settings
When changing an SRDO1 setting the sensor must be in pre-operating state.
The direction 1301h sub id 01h must be disabled by writing 00h to object 1301h sub id 01h.
When the SRDO setting is changed the CRC code must also be changed and activated. Finally the data must be
stored in EEPROM
Example to change SRDO1 refresh time
Load object: 1301h sub id 01h with: 00h disable SRDO1 communication.
Load object: 1301h sub id 02h with: 0064h new SRDO1 refresh time.
Load object: 1301h sub id 01h with: 01h enable transmit SRDO1 communication.
Load object: 13FFh sub id 01h with: xxxxh code from CRC calculation tool.
Load object: 13FEh sub id 00h with: A5h validate new CRC.
Load object: 1010h sub id 01h with: “save” or 65766173h write new SRDO1 refresh time, CRC and
validation to EEPROM.
After a power reset and when the device is set to operational, the transmission time is equal to the desired time.

9Internal diagnostic tests
To ensure safety the hard- and software of the safety sensor is continue checked. When a failure is detected, an
emergency message is sent. After sending this message, the device goes to a safe state, in which no
communication is possible (No SRDO, TPDO and Heartbeat). In this state, a NMT reset will not restart the sensor.
Failure should be analyzed by reading out the emergency message. If the error can be fixed, give the sensor a
new power cycle will restart the communication. If it is a ‘sensor element error (redundancy error), you
might consider to update ‘redundancy compare time’ and/or ‘redundancy compare angle. If the error cannot be
fixed, please contact your distributor.
The receiving application should detect that no communication is possible and shall set the system to a safe
state.

14 EDS files
The “Electronic Data Sheet” (EDS file) is a file format that describes the communication behavior and the object
dictionary entries of a device. In fact it’s a template. This allows tools such as CAN configuration tools to handle
the device properly. The file format is described in CiA306 V1.3.0
The EDS-file contains all possible settings and functions for the device by describing the CAN object dictionary
for the device to be set by CAN commands.
The EDS-file does not contain a customer specific configuration description (the values of the object dictionary,
like i.e. the chosen baud rate, TPDO1 event time, Node ID etc.). For this purpose the customer can generate a so
called DCF-file (Device Configuration File) with all customer specific settings out of the EDS-file. The DCF file is in
fact the incarnation of the EDS-file.
After loading the DCF-file into the device you have to store the settings into EEPROM by index 1010h sub index
01h to store permanently, see “CAN Object Dictionary Entries”.
The EDS-files available for sensors with embedded firmware version D-type described in this document should
have a version D-type also.
The next EDS-files are available at www.dis-sensors.com under ‘downloads’:
•QG_Dtype_1_axis_360v_v*.*
•QG_Dtype_2_axis_30h_v*.*
•QG_Dtype_2_axis_90h_v*.*
