The wiring depends on the heating option selected for the sensor:

  • WMT700 without heating (0 W) and WMT700 with transducer heating only (30 W) require only the standard power supply unit.
  • WMT700 with transducer and arms heating (150 W) requires a second power supply unit.

    The second power supply cannot be mounted inside the ENC722 enclosure.
CAUTION The heating power supply wires of WMT700 are internally connected to each other. If the connection cable has 2 positive heating supply wires, they must be connected to each other. Leaving one terminal unconnected or connecting it to the ground may cause the sensor to malfunction or a short circuit in the power supply.
1 Calculated after cutting the cable.
2 Only for use with non‑heated (0 W) or transducer-heated (30 W) WMT700.
