Flow Sensor Transmission

Hello kinyanjui

In your situation you have checked:

1. The Power Supply to the unit.
2. You have checked the wiring for continuity.
3. You have connected the sensor correctly.

The Controller is saying "Wire Break Alarm ".

Reboot = Reset the Controller, by leaving all connected and disconnecting the electric supply to the controller, at the switchboard or power outlet.

Wait 3 - 5 minutes. (This allows capacitors to discharge in the Controller, and the Controller should go to the Default Position = reboot/re-set.

Switch Power back on after that 3 - 5 minutes.

If you still have a problem after the re-boot/re-set, there are now only 3 possibilities:

1. Sensor is faulty = Open circuit = Replace Sensor
2. Controller is faulty = Replace Controller
3. Sensor and Controller are faulty = Replace both Sensor and Controller
4. With any of the above, if the equipment was new, contact the suppliers.
   

Advise your progress please

Kind Regards....

Thanks sparks i changed the controller first with a simillar one n got the expected resullts as for feridun comment i had checked the status of the transmisson wires n had an expected ohmic value of about approx.0.01 now its workin i dint expect the controlller to be faulty as its new.cheers man! u guys are great.

Hello again, kinyanjui

Your feedback is appreciated.

1-Either the loop resistance of tranmission wires is too high for the controller to bias the sensor, or

2-The controller cannot produce enough bias voltage when supplied with 110VAC.

Please redo the workshop test at 240VAC, with transmission wires this time, and feedback as Sparkstation said.
