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.
