Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
(1) Carry out the Standard Setting procedure as detailed in the relevant paragraph of the Service
menu.
The speed sensor detects the heads of these bolts.
(2) Powered models: Place the tester probes across the terminals of the speed sensor. The
measured signal should be that indicated in Figure 3.12-1. In
addition, when pedalling at 80RPM the frequency of the signal
should be 136Hz.
(3) Self-Powered models: Check the signal at paragraph: 2.9. “Cables”. The measured signal
should be that indicated in Figure 3.12-1 In addition, when pedalling
at 80RPM the frequency of the signal should be 136Hz.
The speed signal can also be observed qualitatively, using a multimeter. The value
should be 0Vdc when the machine is stopped, and gradually increase as the speed
increases.
(4) Update the low kit SW uploading both firmware and brake table. At the end carry out the
Default setting procedure for the low kit parameters.
If you replace ARM/CPU Board and/or Brake Board, check that its SW version is
updated, otherwise install the last version.
