Sensor Wiring
The Rosemount 2240S has a Sensorbus terminal for connection of a water
level sensor. Use the following steps to connect the sensor wires from a water
level sensor to the Rosemount 2240S:
1. Make sure the power supply is switched off.
2. Loosen the four screws and remove the cover on the terminal
compartment.
3. Run the sensor wires through the sleeve at the bottom of the transmitter
housing, see Figure 4-10.
If the 2240S is mounted on a wall or pipe (remote mounting), run the
sensor wires through the appropriate cable gland/conduit entry, see
Figure 2-2 on page 2-2.
4. Connect the sensor wires to the terminals. See information on cable
colors in Figure 4-10.
5. Connect the water level sensor cable shield to one of the three ground
terminals.
6. Make sure the cover sealing is in the correct position.
7. Attach the cover on the terminal compartment and tighten the four
screws.
8. Tighten the conduit/cable glands.
