    When using CAN lines for communication there must be 2 termination points within the system. Termination points are explained further in the Configuration section (installation step 2). What is important at this time is that in order to maximize the efficiency of communication in your CAN network, you must terminate the two components at the extreme ends of your main CAN line.
  • Page 11 Caution: Do NOT use motors or discharge as leverage to tighten monitor. Warning: When installing the monitor on a raised face companion flange, it is critical that the bolts be tightened uniformly to prevent misalignment of the monitor relative to the flange or valve. If the monitor becomes misaligned, the base flange will fracture and fail when the bolts on the “high”...
