Troubleshooting – programming
The manufacturer can assist you in troubleshooting if you have the correct documentation and suf

ficient data to hand. The following are indispensable for this:
• a hydraulic scheme via fax or email (WMF, JPG),
• the complete program via TAPPS file or at least the function data (*.dat file) by email,
• operating system version and controller serial number,
• all existing log files or at least the (temperature) values of the inputs at the time the system
malfunctioned,
• telephone contact for describing the problem – in most cases a written fault description is
not enough.
Troubleshooting in the CAN network
To isolate the error we recommend shutting down part of the network and monitoring when the error
disappears.
General tests:
• Node numbers – no node number must be assigned twice
• Power supply to BUS subscribers (if necessary use the CAN-NT power supply unit)
• Setting of the Baud rate (even when using the CAN BUS converter CAN-BC2)
Wiring test:
All nodes must be switched off for this test.
• Resistance across CAN-H and CAN-L
• If this is in excess of 70 Ω, it indicates incorrect termination.
• If the resistance is below 60 Ω, look for too many terminations or short circuits between
cables/leads.
• Check for short circuits across GND or screen and the signal cables.
• Check for earth loops – for this the screen is undone at each node and the current tested. If
there is a current flow, an earth loop has been created by an unwanted earth connection.
