2240S Installation
To connect the sensor wires for a temperature detector to a Rosemount 2240S do the following:
1. Make sure the power supply is switched off.
2. Loosen the four screws and remove the cover from the terminal compartment.
3. Run the wires for temperature elements and water level sensor through the sleeve at the bottom of
the transmitter housing, see Figure 4-8 .
If the 2240S transmitter 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 8 .
4. Connect the temperature sensor wires to the terminals marked “1” to “16” and “a”, “b”, “c”, and
“d”. Refer to Figure 4-9 , Figure 4-10 , and Figure 4-11 depending on the sensor type and
measurement method that is used.
5. Connect the red, green, white, and black water level sensor wires to the Sensorbus terminal as
shown in Figure 4-8 .
6. Connect the shield on the water level sensor cable to one of the ground terminals.
7. Make sure the cover sealing is placed in the correct position.
8. Attach the cover on the terminal compartment and tighten the four screws.
9. Tighten the cable glands.
