10. APPENDIX B: TROUBLESHOOTING
In this appendix, several problems are included that can occur when the display / totalizer is going to be installed or while it is
in operation.
Flow meter does not generate pulses:
Check:
•
Signal selection SETUP - 51,
•
Pulse amplitude (paragraph 7.5.3 ),
•
Flow meter, wiring and connection of terminal connectors (paragraph 7.5 ),
•
Power supply of flow meter (paragraph 7.5.2 ).
Flow meter does generate "too many pulses":
Check:
•
Settings for Total and Flow rate: SETUP 11-14 and 21-27,
•
Type of signal with actual signal selection - SETUP - 51,
•
Sensitivity of coil input - SETUP - 51 and paragraph 7.5.5
•
Proper grounding of the F110 - paragraph 7.4
•
Use screened wire for flow meter signals and connect screen to terminal 9.
Pulse output does not function:
Check:
•
SETUP 71 - impulse width; is the external device able to recognise the selected pulse width and frequency?
•
SETUP 72 - pulse per X-quantity; is the value programmed reasonable and will the maximum output be under 20Hz?
•
Connections to terminals 4 and 5.
Analog output does not function properly:
Check:
•
SETUP 61 - is the function enabled?
•
SETUP 62 / 63: are the flow-levels programmed correctly?
•
Connection of the external power-supply according specification
•
Is the unit itself separate powered?
