2.3 Handling of Wheel Units
The Wheel Units are equipped with a built-in, high-
performance battery with a capacity of 6.5 Ah.
2.3.1 Further documents
UL (Underwriters Laboratories Inc.):
Standard for Lithium Batteries
UL 1642 - Fifth Edition, March 2012
UN (United Nations):
UN Recommendations on the Transport of Dangerous
Goods; Model Regulations.
UN Recommendations on the Transport of Dangerous
Goods; Manual of Tests and Criteria; Part III, sub-sec-
tion 38.3.

ments for portable sealed secondary cells, and for
batteries made from them, for use in portable applica-
tions - Part 2: Lithium systems.
2.3.2 Storing the Wheel Units
During storage, the power connector must be removed
and the dummy plug installed in order to separate the
battery from the other electronics to inhibit parasitic
capacitance.
Self discharge
The typical self discharge in the rst year when held at a
temperature of 20 °C is less than 5 %, with a charge level
between 15 and 50 %.

KiRoad Wireless P1 System, Type 9813B... and Type 9811B...
9813B_002-790e-11.23Page 8
Storage temperature
The recommended storage temperature is between 15
°C and 30 °C without direct sunlight in a dry, clean, well-
ventilated place.
Storage outside of these temperatures can lead to a
greater amount of self discharge, lower performance and
swelling of the battery cells.
Minimum charge level during storage
A minimum charge level of 3.62 V at the end of storage is
necessary to prevent deep discharge.
If the battery voltage is low or even 0 V after storage, the
battery must be charged as quickly as possible to avoid
the voltage of one or more cells falling below a level
where the cell can be damaged.
To do this, "wake up" the battery by connecting the
supplied charging device.
When the battery receives no charge, it is likely that the
voltage in one or more cells has fallen below the voltage
level below which it is prohibited from accepting a charge
for safety reasons. Because of this, the electronic protec-
tion circuit is activated and inhibits further charging.
A deep discharge (below 2.0 V) can seriously and
irreversibly inuence the performance and service life of
the battery!
If the battery is to be stored for more than 3 months to
less than one year, proceed as follows:
Regular monitoring of the battery voltage, at least
once every 6 months
If necessary: Charge the battery up to 50 % of its
capacitance

Important notes
Page 99813B_002-790e-11.23
2.3.3 Using the Wheel Units after a long storage period
After a long storage period, the following procedure is rec-
ommended:
Complete discharging of the battery
Preferably, run a complete charge / discharge cycle.
Otherwise, it may take 2 to 3 cycles until the maximum
capacitance is available again
Completely charge the battery
2.3.4 Safety information
Do not dismantle the battery
Do not expose it to heat or ames
Do not short circuit it
Do not drop or hit it forcibly
Only charge it with the original charging device
2.3.5 Transporting the Wheel Units
Legal conditions
Due to the lithium ion battery installed, the wheel units
must be shipped as hazardous materials. The UN number
UN 3481 applies.
International and national tra󰀩c regulations for transport
by air, sea, road and rail (ICAO / IATA, IMDG, ADR, RID
...) are legally binding. Individuals who prepare Wheel
Units for transport must satisfy all of the requirements,
including, but not limited to, special requirements, pack-
aging regulations, labeling and training.
Overview
Individuals who prepare Wheel Units for transport must
specify the applicable measures and instructions care-
fully. Additional information on this can be found in the
applicable o󰀩cial documentation:

3. Product description
3.1 Overview
The KiRoad Wireless P1 Onboard Unit serves as access
point for up to four KiRoad Wireless P1 Wheel Units, Type
9811B…, and enables measurement data to be output
to the connected data acquisition device. The connected
RoaDyn wheel torque transducers automatically log on
and identify themselves after the Onboard Unit is turned
on. Any sensor-specic information is automatically read
into the device so that the system is quickly ready for
operation without additional user action. The signal is out-
put to the data acquisition system via DTI, Ethernet, or
CAN bus interface (for all signals) and optionally via ana-
log outputs (8 selectable channels). The zero adjustment
of the torque signals can be triggered using the remote
control or via Ethernet or USB from the laptop or PC using
the KiCenter software.
The complete measurement system consists of three
main components: The RoaDyn P1xy wheel torque trans-
ducer, the data transmission module (Type 9811B...), and
the Onboard Unit (Type 9813B...) located inside the vehi-
cle. Because each KiRoad Wireless P1 system sets up its
own encrypted WLAN network, several KiRoad Wireless
systems can work together simultaneously without prob-
lems; for example, several vehicles, each equipped with
4 RoaDyn P1xy.
If a Kistler DTI-Logger is used for data acquisition, only
one cable is required for the Onboard Unit to transfer the
data, to provide power, and congure the Onboard Unit
via KiCenter. Otherwise, the CAN signals and analog
signals can also be output. System conguration is user-
friendly via KiCenter using Ethernet or USB. All transmit-
ted measurement data can be viewed in KiCenter.

5. Installation and connections
5.1 Description of the Wheel Unit and overview of the LED codes
Fig. 3: KiRoad Wireless P1 Wheel Unit
1Initialization switch
2Indicator LEDs
3Power supply port
Each LED on the control panel represents a wheel posi-
tion number (position 3 is used as an example in the fol-
lowing descriptions).
If the Wheel Unit LEDs behave di󰀨erently than described
below, refer to the list of error LED patterns on page 19.
Fig. 4: Explanation LED patterns
After switching on, the initialization switch (on/off switch) is used to control the Wheel Unit. While the
switch is pressed, one of the LEDs lights up every second (from 1 ... 4) until all LEDs are illuminated.
The function performed depends on how long the switch is pressed (see next page).

Installation and connections
Page 179813B_002-790e-11.23
<2 s Initialization: Indicates the position that is requested (the corresponding LED lights up for 3
seconds)
Measurement: Displays the assigned position (the corresponding LED lights up for 3 sec-
onds) and performs a wheel search (hot-plugin). It is not necessary to supply power to the
Wheel Unit again to detect a connected wheel if it has been mounted (or removed) after pow-
er-on.
This functionality is disabled during steps 1 ... 3 of the positioning process.
>2 s Activate the positioning procedure to pair the Wheel Unit with an OBU and to assign the posi-
tion number. The positioning procedure is described on the next page. Make sure that the
OBU is in positioning mode!
>7 s Switch o󰀨 the Wheel Unit.
LED operating status (position LED ashes every three seconds)
1 short ash: Normal operating mode, wheel and angle measurement connected.
2 short ashes: No ID module OR no angle measurement mechanism detected.
3 short ashes: No ID module AND no angle measurement mechanism detected.
Sequence in normal operation
1. All LEDs o󰀨:
The Wheel Unit is not supplied with power. Turn the unit on by pressing
the button in the center of the control panel.
2. All LEDs on:
After power-on, all LEDs light up while the Wheel Unit performs its basic
initialization (approx. 5 s).
3. All LEDs ash slowly:
Basic initialization completed. Waiting for the end of the wi module
boot phase.
4. 1 LED wave (1►2►3►4►3►2, ⟲):
Wi module initialized. Connection to the OBU and request of the posi-
tion. If the wheel unit has not yet been paired with an OBU, the initializa-
tion process is aborted here. In this case start the positioning process
as explained on the next page.
5. 1 LED on (e.g. LED 3):
Connection to OBU successful, requested position (1 ... 4) confirmed.
The corresponding LED lights up for 3 ... 5 seconds.
6. 1 LED flashes (e.g. LED 3):
The Wheel Unit is connected, the data measurement is running. A LED
flashes every 3 seconds. The flashing LED represents the assigned
position number. This is the normal operating mode (see also above:
LED operating status).
Steps 1 ... 5 are called "initialization phase". Step 6 is called the "measurement phase".
It is recommended to wait until step 4 before starting the positioning process.

9813B_002-790e-11.23Page 18
Positioning procedure
1. Start sequence for positioning [1+2►2+3►3+4►off]:
The activation of the positioning mode is indicated by this short LED
sequence. After that, the system switches to return mode and the user
must press the power button within 5 seconds to change the selection
(see next steps).
2a. All LEDs off:
Return mode. If the button is not pressed for 5 seconds while all LEDs
are off, the positioning mode is exited without changing the settings
(see step 2b, otherwise step 3).
2b. Exit the positioning mode [1+3►2+4, ⟲ 3x]:
The Wheel Unit returns to the previous mode. Positioning process fin-
ished.
3. Select position:
The user can select the desired position for this Wheel Unit by pressing
the power button several times. Each press increases the desired posi-
tion by 1 and the corresponding LED lights up. If the switch is pressed
while position 4 is selected (LED 4 is illuminated), the system switches
back to return mode (see above). If the button is not pressed for 5 sec-
onds, the active selection is stored and the Wheel Unit starts to pair
with the OBU and the position request. Make sure that the OBU is
also in positioning mode at this time!
4. 1 LED ashes slowly (e.g. LED 3):
The LED representing the requested position flashes while the
Wheel Unit tries to establish a connection to the OBU and reserve the
selected position. This may take some time.
5. 1 LED on (e.g. LED 3):
Pairing with the OBU successful, requested position (1 ... 4) confirmed.
The corresponding LED lights up for 3 ... 5 seconds. The positioning
mode is exited automatically and the Wheel Unit waits for the connec-
tion or reset command from the OBU.
