10.2 error messages
Error messages are only displayed at the Read level. They are shown alternately (flashing) with the process value.
error cause troubleshooting
ERR1 Value cannot be displayed
(e.g. value too high). • Change the fow rate unit
(see chapter 9.6.1 Unit – Setting the unit for
the flow rate).
ERR2 Input frequency of sensor higher than 600 Hz. • Use a suitable sensor.
ERR3 Calculated output current not within range of
4-20 mA or K factor = 0. • 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.
ERR4 Limit values of the flow rate range associated to
the 4-20 mA current output not correct (Low >
High). Correctly set the values.
ERR5 The K factor times the set volume (converted in
liters) pro pulse is < 1. • Check the set K factor.
• If the K factor is correct, enter a higher volume
pro pulse so that the K factor times the set
volume (converted in liters) pro pulse is equal
to or higher than 1.
