APPENDIX B PROBLEM SOLVING
In this appendix, several problems are included that can occur when the F115-P is going to be
installed or while it is in operation.
Flowmeter does not generate pulses:
Check:
▪ Signal selection;
▪ Pulse amplitude;
▪ Flowmeter, wiring and connection of terminal connectors;
▪ Power supply of flowmeter.
Flowmeter generates "too many pulses":
Check:
▪ Settings for total and Flow rate;
▪ Type of signal selected with actual signal generated;
▪ Sensitivity of coil input;
▪ Proper grounding of the F115-P;
▪ Use screened wire for flowmeter signals and connect screen to terminal 9. (unless connected at
sensor).
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:
▪
output be under 20Hz?
▪ width; is the external device able to recognize the selected pulse width and frequency?
Flow rate displays "0 / zero" while there is flow (total is counting):
Check:
▪ are the K-Factor and time unit correct?
▪ The unit has to count the number of pulses according to setup 26 within the time according to
setup 27. Make sure, setup 27is 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 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.
For a not recoverable error, keep the error code at hand and contact your supplier.
