PROBLEM SOLVING
In this appendix, several problems are included that can occur when the F127-P-EL 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 F127-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.
Flow rate displays "0 / zero" while there is flow (total is counting):
Check:

SETUP 22 / 25 and 41-42: 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
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.
[d] 8 =: Analog input error;
[d] 16 =: PT100 ADC error .
Recoverable by the end user:
[d] 32 =: Correction calculation factor (A) error;
[d] 64 =: Correction calculation factor (B) error;
[d] 128 =: Temperature Pressure Compensation (TPC A) calculation error;
[d] 256 =: Temperature Pressure Compensation (TPC B) calculation error;
[d] 512 =: PT100 sensor 1 out of range error;
[d] 1024 =: PT100 sensor 2 out of range error.
For a not recoverable error, keep the error code at hand and contact your supplier.
