APPENDIX B: PROBLEM SOLVING

In this appendix, several problems are included that can occur when the F131-P is going to be
installed or while it is in operation.

Flowmeter does not generate pulses:

Check:



Signal selection SETUP - 61,



Pulse amplitude (par. 4.4.3.),



Flowmeter, wiring and connection of terminal connectors (par. 4.4.3.),



Power supply of flowmeter (par. 4.4.2.).

Flowmeter generates "too many pulses":

Check:



Settings for total and Flowrate: SETUP 11-14 and 21-27,



Type of signal selected with actual signal generated - SETUP - 61,



Sensitivity of coil input - SETUP - 61 and par. 4.4.3.



Proper grounding of the F131-P - par. 4.4.1.



Use screened wire for flowmeter signals and connect screen to terminal 9. (unless connected at

sensor)

Analog output does not function properly:

Check:



SETUP 71 - is the function enabled?



SETUP 72 / 73: are the flow-levels programmed correctly?



connection of the external power-supply according to the specification.

Pulse output does not function:

Check:



SETUP 81 - pulse per “x” quantity; is the value programmed reasonable and will the maximum

output be under 20Hz?



SETUP 82 - impulse width; is the external device able to recognize the selected pulse width and

frequency?

Flowrate displays "0 / zero" while there is flow (total is counting):

Check:



SETUP 22 / 25: are the K-factor and time unit correct?



SETUP 26 / 27: The unit has to count the number of pulses according to SETUP 26 within the

time according to SETUP 27. Make sure that 27 is set to 10.0 seconds for example : the result is
that the unit has at least 10 seconds time to measure the number of pulses according to SETUP
26.

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 5-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

If the alarm occurs more often or stays active for a longer time, please contact your supplier.
