Possible error cases 

In case of an unexpected defect of the electronics, it outputs a constant value of approx. 2.5 V, the value 
corresponds to a torque of 0 Nm. 

If  the  sensor  is  blocked,  please  contact  the  manufacturer  immediately  and  do  not  continue  to  use  the 
product. 

Scope of delivery 

The  sensor  system  consists  of  a  calibrated  sensor,  including  a  connection  cable  (corresponding  to  the 
configuration) and a loose adapter. In case of the BSA 73 mm variant, an additional spacer is included in the 
right bearing shell. The signal recording and processing is integrated in the housing.

 

Handling and transport 

During  handling,  storage  and  transport  make  sure  the  sensor  is  not  exposed  to  magnetic  fields  (e.g. 
demagnetizing coils or permanent magnets). It must also be ensured that no magnetic tools are used during 
mounting. 

Important technical safety instructions 

 

Opening the sensor is not permitted. 

 

The  sensor  must  not  be  subjected  to  any  mechanical  loads  when  not  installed  (drops,  knocks, 
vibrations, etc.). 

 

To prevent damage caused by a short circuit on the connecting cable, a suitable back-up fuse (approx. 
1 A nominal current) must limit the current supply to the sensor. 

 

The sensor may only be operated within the permitted load limits. These can be found accordingly 
in the standard DIN 15194:2018-11 and ISO 4210:2018. Cycles Safety requirements for bicycles part 
2: Requirements for city bicycles chapter 4.13: Pedals and pedal/crank drive system 

 

Reverse polarity or overvoltage on the connecting leads can damage the sensor. 

 

Routing the wires outside the bike frame can cause interference with the sensor. NCTE recommends 
routing the connection and data lines inside the frame. If internal routing is not possible for technical 
reasons, the irradiance sensitivity must be re-evaluated accordingly by the EPAC manufacturer. 

Disposal 

Dispose  of  the  article  and  all  associated  components  via  an  authorized  disposal  company.  Observe  the 
currently  applicable  regulations.  If  in  doubt,  contact  your  waste  disposal  facility  to  find  out  about 
environmentally compatible disposal.
