PROBLEM SOLVING
In this appendix, several problems are included that can occur when the B-SMART is going to be installed or
while it is in operation.
Flowmeter does not generate pulses
Check:
•
Signal selection SETUP 3.1.
•
Pulse amplitude (paragraph 3.3.4).
•
Flowmeter, wiring and connection of terminal connectors (paragraph 4.7.1).
•
Power supply of flowmeter (paragraph 4.5.2).
Flowmeter generates "too many pulses"
Check:
•
Settings for Total (SETUP 1) and Flowrate (SETUP 2).
•
Type of signal selected with actual signal generated (paragraph 3.3.4),
•
Sensitivity of coil input.
•
Proper grounding of the B-SMART, avoid ground loops.
•
Use screened wire for flowmeter signals and connect screen to the ground input terminal of the
flowmeter input.
Flowrate displays "0 / zero" while there is flow (total is counting)
Check:
•
SETUP 2.2 / 2.4: are the K-factor and time unit correct?
Analog output does not function properly
Check:
•
SETUP 4.1: is the function enabled?
•
SETUP 4.2 / 4.3: are the flow-levels programmed correctly?
•
SETUP 4.4 / 4.5: are the 4mA and 20mA tuned correctly?
•
Connection of the external power-supply according to the specification.
Pulse output does not function
Check:
•
SETUP 5.1 - mode: is the correct function selected?
•
SETUP 5.1 - mode: is the external device able to recognize the selected pulse width and frequency?
•
SETUP 5.2/5.3 -
amount per “x” quantity: is the value programmed reasonable?
The password is unknown
If the PIN cannot be retrieved, 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 key several
times to display the error code. The codes are:
0001
= display error
0002
= data-storage error
0004
= initialization error
When multiple alarms occur, the error code shown is the sum of the error codes as given above.
E.g. 0005 is a combination of error code 0001 and 0004.
If the alarm occurs more often or stays active for a long time, please contact your supplier.
