Multidrop Installation
• Unscrew cover from transmitter.
• Lift the handle and pull the bucket with the electronics out of
the enclosure.
• Turn the bucket over and pull off the 5-pin connector.
• Simply connect the incoming and outgoing three wires for power and signal
to the terminal, as indicated on the label on the bottom of the bucket.
• Plug connector back into socket.
• The cable shielding should be connected at the controller only.
• Place bucket back into the enclosure.
• Screw cover back on, until it is seated.
NOTE
All transmitters need to be setup individually. Transmitters on the same
multidrop line must each be configured to a different “polling address”
which is between “1” and “15” (Section 5.9, Communication).
The address numbers should start with “1”, be consecutive, and may not
be used twice. The number of transmitters on one loop may not exceed
15 and is dependent on the power supply and cable used.
The permissible loop resistance of the cable is shown in
Section 2.2.3, Installing Electrical Connections at the Controller.
