4.5 Error messages in measuring mode
The following list contains all errors which may occur during flow measurment. Errors are displayed when
”YES” is selected in Fct. 1.04 DISPLAY, subfunction ”DISP. MSG.”.
Error message Description of error Elimination of error
LINE INT. Power failure Note: Cancel error in RESET/QUIT. menu
no counting during power failure Reset totalizer if necessary.
OVERFLOW I Current output overranged. Check instrument parameters and
or (flow rate > measuring range) correct if necessary. After elimination of
OVERFL. I2 the cause, the error message is
cancelled automatically.
See Sections 6.4 and 6.7.
OVERFLOW P Pulse output P Check instrument parameters and
or or correct if necessary. After elimination of
OVERFL. P2 Pulse output range P2 exceeded the cause, the error message is
(flow rate > modulation range) cancelled automatically.
See Sections 6.4 and 6.7.
I SHORT or * Current output I or I2 externally Check mA loop and increase load using
I2 SHORT shorted or load < 15 Ω additional resistor if necessary.
I OPEN or * mA loop interrupted by current Check mA loop and reduce load to
I2 OPEN output I or I2 or load > 500 Ω 500 Ω if necessary.
TOTALIZER Overflow of internal totalizer Delete error message in RESET/QUIT
menu, see Sect. 4.6
ADC Analog/digital converter range Set Fct. 3.06, subfunction ADC GAIN
exceeded to ”10”. See Sections 6.4 and 6.7.
If error message does not disappear,
consult factory.
ADC-PARAM. Check sum error Replace ADC printed circuit board
ADC-HARDW. Hardware error A/D converter Replace ADC printed circuit board
ADC GAIN Hardware error A/D converter Replace ADC printed circuit board
FC-HARDW. Hardware error on field current PCB Replace field current PCB
FATAL.ERROR Fatal error, measurement interrupted Replace electronic unit or consult factory.
EP PARAM. Parameters of “Empty Pipe” are wrong Error shut off automatically EPD function.
Please check calibration values!
Value Empty Pipe – Value Full pipe
≥ 10
Values must be in range of 0 – 150.
