Sensor Error
If a sensor error code is displayed after performing the
MANUAL SENSOR READ function, use the following
procedure to determine the cause of the error.
Follow the steps in the table in order until the error clears or
the problem is identifi ed.

Table 8 - Sensor Error Code Procedure

Step
1 If the sensor is not buried in the soil, verify there is no
obvious external damage.
2 Verify there is a Rain Bird logo on the sensor; if not,
the sensor is not Rain Bird certifi ed and needs to be
replaced.
3 Ensure the sensor probes are completely buried in the
soil when the MANUAL SENSOR READ is performed, or
the sensor will not work properly.
4 Turn the dial to MANUAL SENSOR and press READ;
continue with Step 5 if the error does not clear.

5 Check the wiring connections to the terminals inside
the ISDL-2400:
a) Inspect wires for open and/or short circuits.
b) Verify wires are connected to the correct terminal
(PWR, GND, DATA) and the correct channel (Ch1 or
Ch2). Refer to the diagram on page 81.
6 Check the wiring connections at the DB connectors
(inside the valve box):
a) Inspect wires for open and/or short circuits.
b) Verify wiring connections are correct. Refer to the
diagram on page 76.
7 Turn the dial to SENSOR SETUP and select "Scan
Sensors". If a sensor address is detected, proceed to
step 8. If no address is detected, go to step 9.
8 Select " Remove" to remove the suspect sensor from
the data logger. Then select "Add Sensor" to reinstall
the sensor. Turn the dial to MANUAL SENSOR and press
READ.
9 If the error code persists, record the sensor address,
sensor error code, and ISDL node ID. Contact Rain Bird
