6.1.4 Testing Loop Integrity (Data Cables) &
Diagnosing Fault Location
Figure 6.3 — Illustration of Testing Loop Integrity (Data Cables)
Performing this check after the 0V and Power checks has the
following benefits:
• The previous checks have made sure the Remote Units have
Power and that the Loop is intact,
• The Commissioning Process and the “SYSTEM OK” LED can
be used to locate faulty connections or wiring,
• Only the CAN H and CAN L terminations need to be
checked, since the other connections have been checked
previously.
Refer to Section 6.2.4 for details on fault finding using the
Commissioning process, and Section 6.3.3.2 for fault finding
using the “SYSTEM OK” LED.
