Description
The H
S concentration in the air is
2
more than 1000 ppm.
The H
S concentration in the air is
2
more than the H₂S gas limit (or H2S
GAS LIMIT) setting.
The H
S concentration in the liquid
2
is more than 5 mg/L.
The H
S concentration in the liquid
2
is more than the H₂S liquid limit (or
H2S LIQUID LIMIT) setting.

A calibration is due.
Solution
Contact technical support to repair or replace
the sensor.
Note: If the sensor is without power for 1 year or more,
an internal battery failure can occur.
Refer to the calibration instructions supplied
with the calibration cap and flow regulator.
Make sure that all of the steps shown are
completed as shown in the calibration
instructions.
Examine the sensor cables for damage.
Examine and the sensor cable connections.
Examine the sensor cables for damage.
Examine and the sensor cable connections.
Connect a GS1440 or GS2440EX sensor to
the gateway.
Solution
Move the sensor to a location with a
lower concentration of H
Increase the H₂S gas limit (or H2S
GAS LIMIT) setting as necessary.
Move the sensor to a location with a
lower concentration of H
Increase the H₂S liquid limit (or H2S
LIQUID LIMIT) setting as necessary.
Complete the calibration.
Calibrate the sensor. Refer to the
documentation supplied with the
