Error Description
Causes
Solutions
The analyzer is at the limit of it's
measuring capability. Check the sensor
setup to ensure that the sensor is operating
properly. Service or replace the sensor if
necessary.
E1.0 Reading
is
off-
scale. Display
shows [+Err].
The internal A/D converter is at
the top of the scale. The
analyzer cannot measure higher
chlorine values.
The analyzer needs electronic adjustments.
Arrange for servicing.
E1.2 Electrode
efficiency would
be less than 20%.
Previous setting
retained.
Improper electrode setup or
electrode failure.
Set up electrode, then redo calibration.
Also refer to Troubleshooting section.
E1.3 Sensor
efficiency
would be more
than 300%.
Previous setting
retained.
No chlorine signal or signal
from sensor very weak.
Check electrode connection, then redo
calibration. Also refer to Troubleshooting
section.
E1.4 pH
compensator
is off-scale.
pH sensor is not connected.
Check pH sensor connections and/or select
manual pH compensation.
TC is not connected.
Check TC connections or install TC.
E1.5 Temperature
compensator is
off-scale.
Process is outside of TC
operating range of -5 °C to
105 °C.
Use manual temperature compensation.
Error Description Causes
Solutions
Temperature is less than
-5 °C.
Verify process and sensor
location.
E2.1
Temperature reading is off-
scale. Temperature is less
than -5 °C.
Electronic temperature
calibration necessary.
Follow procedure in Hardware
Alignment section.
Attach temperature
compensator.
Connect resistor to TC
terminals to simulate a constant
temperature. Refer to
Hardware Alignment section.
Temperature compensator is
not attached.
Verify process and sensor
location.
Temperature is greater than
105 °C .
E2.2
Temperature reading is off-
scale. Temperature is greater
than 105 °C.
Electronic temperature
calibration necessary.
Follow procedure in Hardware
Alignment section.
