Error message (faulty operation)
When an error message is displayed, contact the azbil Group. Repair at Azbil
Corporation is required.

Failure location
Cause
Er0
1
Flow sensor
Flow sensor error
Er02
Temperature sensor The cause may be an error or burnout of the sensor for
temperature detection. Alternatively dust, moisture or
oil from the fluid may have adhered to the sensor.
Er03
Flow sensor
Temperature sensor
There may be an error or burnout of the flow sensor or
temperature sensor. Alternatively dust, moisture or oil
from the fluid may have adhered to the sensor.
Er04
Pressure sensor
The cause may be an error or burnout of the pressure
compensating sensor.
Er05
Flow sensor
Pressure sensor
The cause may be an error or burnout of the flow sen-
sor or pressure sensor. Alternatively dust, moisture or
oil from the fluid may have adhered to the sensor.
Er06
Temperature sensor
Pressure sensor
The cause may be an error or burnout of the tem-
perature sensor or pressure sensor. Alternatively dust,
moisture or oil from the fluid may have adhered to the
sensor.

Flow sensor
Temperature sensor
Pressure sensor
The cause may be an error or burnout of the flow
sensor, temperature sensor, or pressure sensor.
Alternatively dust, moisture or oil from the fluid may
have adhered to the sensor.
Er08
EEPROM
The cause may be an error in the nonvolatile memory
used by the internal microcomputer.
Note. While an error is displayed, the analog output (4–20 mA) is the output that is set for
burnout. The default setting for burnout is downscale output (3 mA max.).
