APPENDIX B: PROBLEM SOLVING
In this appendix, several problems are included that can occur when the F070-A is going to be
installed or while it is in operation.
Level / height displays "0 / zero" while a higher signal is available:
Check:
SETUP 13 is the span correct?
SETUP 14: is the offset value correct?
check the input calibration SETUP 53 and 54.
Range error
Range error (LO RANGE or HI RANGE): the input value is at least 5% above or below the
calibrated measurement range SETUP 53, 54. Do recalibrate the input if desired.
The pass code is unknown:
If the pass code is not 1234, there is only one possibility left: call your supplier.
ALARM
When the alarm flag starts to blink an internal alarm condition has occurred. Press the "select
button" several times to display the 4-digit error code. The codes are:
0001: irrecoverable display-data error: data on the display might be corrupted.
0002: irrecoverable data-storage error: the programming cycle might have gone wrong: check
programmed values.
0003: error 1 and error 2 occurred simultaneously
The alarm condition will almost certainly be handled internally and if all mentioned values still appear
correct, no intervention by the operator is needed. If the alarm occurs more often or stays active for
a longer time, please contact your supplier.
