Remote Display Wiring and Power Up
The Remote Mount Display and Interface system consists of a local transmitter and a remote mount LCD display assembly. The local 3051S transmitter assembly includes a Junction Box housing with a three position terminal block integrally mounted to a SuperModule. The remote mount LCD display assembly consists of a dual compartment PlantWeb housing with a seven position terminal block. See Figure 4 on page 9 for complete wiring instructions. The following is a list of necessary information specific to the Remote Mount Display system:
•Each terminal block is unique for the remote display system.
•A 316 SST housing adapter is permanently secured to the remote mount LCD display PlantWeb housing providing an external ground and a means for field mounting with the provided mounting bracket.
•A cable is required for wiring between the transmitter and remote mount LCD display. The cable length is limited to 100 ft.
•50 ft. (option M8) or 100 ft. (option M9) cable is provided for wiring between the transmitter and remote mount LCD display. Option M7 does not include cable; see recommended specifications below:
Cable type: Recommend Belden 3084A DeviceNet cable or Belden 123084A Armored DeviceNet cable. Other comparable cable may be used as long as it has independent dual twisted shielded pair wires with an outer shield. The Power wires must be 22 AWG minimum and the CAN communication wires must be 24 AWG minimum.
Cable length: Up to 100 feet depending upon cable capacitance.
Cable capacitance: The capacitance from the CAN communications line to the CAN return line as wired must be less than 5000 picofarads total. This allows up to 50 picofarads per foot for a 100 foot cable.
