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?
The password is unknown:
If the password is not 1234, there is only one possibility left: Call your supplier.
