APPENDIX B: PROBLEM SOLVING
In this appendix, several problems are included that can occur when the F112-A is going to be
installed or while it is in operation.
Analog output does not function properly:
Check:
is the analog output enabled?
are the flow-levels programmed correctly?
connection of the external power-supply according to the specification.
Pulse output does not function:
Check:
Pulse per “x” quantity (amount); is the value programmed reasonable and will the maximum
output be under 20Hz?
Amount; is the external device able to recognize the selected amount?
Flow rate displays "0 / zero" while there is flow (total is counting):
Check:
are the Span and time unit correct?
Linearization does not work:
Check:
is the function enabled?
are all M-Factors and the frequency entered correctly?
The password is unknown:
If the password 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 error code. When multiple errors arise at the same time, their
error codes are added and their sum is shown. The digital [d] codes are:
Not recoverable by the end user:
[d] 0 = no error;
[d] 1 = display error;
[d] 2 = data-storage error;
[d] 3 = error 1 + error 2 simultaneously;
[d] 4 = initialization error.
[d] 10 = linearization error (calculated M-Factor out of range)
For a not recoverable error, keep the error code at hand and contact your supplier.
