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.
