OEM responsibility
The OEM of a machine or vehicle in which Danfoss products are installed has the full responsibility for all
consequences that might occur. Danfoss has no responsibility for any consequences, direct or indirect,
caused by failures or malfunctions.
•Danfoss has no responsibility for any accidents caused by incorrectly mounted or maintained
equipment.
•Danfoss does not assume any responsibility for Danfoss products being incorrectly applied or the
system being programmed in a manner that jeopardizes safety.
•All safety critical systems shall include an emergency stop to switch off the main supply voltage for
the outputs of the electronic control system. All safety critical components shall be installed in such a
way that the main supply voltage can be switched off at any time. The emergency stop must be easily
accessible to the operator.

CWH1000 compliance statement
IC: 5969A-PROFLEX1; FCC ID: TFB-PROFLEX1
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
“Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
•Consult the dealer or an experienced technician for help.”
“Changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment”
“This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the
following two conditions: (1) this device may not cause interference, and (2) this device must accept any
interference, including interference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de
licence. L’exploitation est autorisée aux deux conditions suivantes: (1) l’appareil ne doit pas produire de
brouillage, et (2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d’en compromettre le fonctionnement.

CWH1000 theory of operation
The CWH1000 CAN Wireless Hub is paired with up to (10) WMSS1000 Wireless Multi-Sonic Sensors at a
time. The hub collects data from all of the sensors and transmits this data on the CAN bus acting as a
wireless gateway between the sensors and the machine CAN bus. The hub sends out a wireless beacon
on two channels containing sensor operational information. The hub receives the information and
calculates when to respond back in a predetermined time. If the sensor does not receive the wireless
beacon, it will change to the alternate channel and wait for a beacon from the hub.

CWH1000 mechanical installation
The CWH1000 contains radio antennas. For best performance follow the guidelines listed below.
The CWH1000 should be mounted:
•In a central location on the machine with respect to the wireless sensors.
•As high on the machine as possible.
•In a vertical position.
•Away from metal.
•Using only the mounting holes provided.
Failure to follow these guidelines could result in a decrease in performance.
