HOOTING
FT-111 weighing indicator had been designed as a very reliable and virtually error free instrument. However, if there is an
error occurs, do not attempt to repair the equipment before understanding what caused the error. Note the problems you
have with your instrument and the error messages shown on the display. Then try to solve the problem according to the
error table given below.
ERROR CODE
DESCRIBTION
THINGS TO DO
Weight is too low
- Check the load
- Load cell or instrument could be
broken.
Over Load
LC Err
Load exceeds the operation range
- Check the load
- Check the calibration
- Load cell or instrument could be
broken.
+POWERONZEROERR
Weight is out of power on zero
range.
- Press
key to start indication
Without zeroing and call service.
-POWERONZEROERR
LOW VOLT PWR OFF
Power source voltage is less than
9 VDC.
- Check the power supply voltage.
HIGH VOLT PWROFF
Voltage is more than 30 VDC.
E01 ADC ERROR
ADC initialization error.
ADC could not initialize at power
on. ADC or its interface circuitry
has a malfunction.
- Power off the instrument reenergizes
it after 30 seconds.
- Check external load cell connection.
- Check load cell connector in the
instrument.
- Change main board or second scale
board.
E02 ADC ERROR
ADC conversion error.
ADC could not convert the load
cell signal. ADC or its load cell
connection circuitry may have a
malfunction.
E03 ADC ERROR
ADC data is out of the range.
ADC could not convert the load
cell signal in range. ADC or its
load cell connection circuitry may
have a malfunction or load cell
excitation voltage is too low.
E09 DISPLAY COMM
Communication error between
display board and main board.
- Power off the instrument reenergizes
it after 30 seconds.
- If not, change main board.
E10 NVM VERSION
NVM version error. Factory default
will be loaded.
- If you changed the E
2
ROM ( U13 ) press
Enter key. The factory defaults will be
loaded.
- If not, change main board.
E20 CALIBRATION
Checksum error of calibration
coefficients.
- Check the scale performance.
- Recalibrate the scale.
- Change mainboard.
E21 SETUP ERROR
Check sum error of parameters.
- Check the scale performance.
- Recalibrate the scale.
- Change mainboard.
E22 CHECKSUM ERR
Checksum error of the data.
- Change E
2
ROM ( U13 ).
E23 HEADER ERR
Header checksum error.
- Press enter key and re-enter the
headers.
- Change E
2
ROM ( U13 ).
E24 FOOTNOTE ERR
Footnote checksum error.
- Press enter key and re-enter the
footers.
- Change E
2
ROM ( U13 ).

- Press enter key and re-enter the
fieldbus setup.
- Change E
2
ROM ( U13 ).
E26 SETPOINT ERR
Setpoint (limit values) checksum
error.
- Press enter key and re-enter the
setpoint (limit ) values.
