error messages

Error messages are only displayed at the Read level. They are shown alternately (flashing) with the process value.
error cause
ERR1 Value cannot be displayed
(e.g. value too high).
ERR2 Input frequency of sensor higher than 600 Hz.
ERR3 When operating as a flow transmitter:
Calculated output current not within range of
4-20 mA or K factor = 0.
When operating as a pulse divider:
Calculated output frequency higher than 600 Hz
or K factor = 0.
ERR4 Limit values of the flow rate range associated to
the 4-20 mA current output not correct (Low >
High).

troubleshooting
• Change the fow rate unit
(see chapter 9.4.1. Unit – Setting the unit for
the flow rate).
• Use a suitable sensor.
• Correctly set the flow rate range associated to
the 4-20 mA current output.
• Use a different sensor and/or correctly set the
K factor of the fitting used.
• Change the division ratio
(setting of pulse dividing K factor).
• Use a different sensor and/or correctly set the
K factor of the fitting used.
Correctly set the values.
