Figure 4: Wiring Transducers to Controller
The current output transmitter drives a maximum load of 600 ohms. If an external current loop power supply
is provided, the transmitter drives a maximum load of 1,000 ohms. Multiple current outputs share a common
lowside.
seAling oPenings in enclosure
After you have completed installation of the conduit and cables, seal around the openings in the controller
enclosure to prevent moisture entry.
Caution: Only use Sikaflex™ 1A polyurethane sealant or Dow Corning RTV 739 or RTV 738. Other sealants may
contain acetic acid, which is harmful to electronics.
synchronizAtion of trAnsducers
If you use the same conduit to run transducer cables from more than one UltraWave Series controller, the units
must be synchronized. To do this, wire the synchronize terminal blocks (TB3) on the main boards of the controller
to each other. TB3 is on the left side of the motherboard, to the right of the ribbon cable. Refer to Appendix E.
The synchronize cable can be run in the same conduit as the transducer cable.
