Flow Sensor - BIO UV MP030 Serie Notice De Montage Et D'entretien

E. FLOW SENSOR
The flow sensor starts the unit when the flow is present and stops it when the flow rate
is insufficient in order to ensure sufficient time for lamp cooling.
The flow sensor is located on the reactor as on this picture:
At the start-up of reactor, it is NECESSARY to carry out a calibration on the basis of the
1. Provide power to the cabinet, lamp(s) off
2. Turn filtration on
3. Adjust filtration flow to the minimum (e.g.: By-Pass opening)
4. Press on the ► button of the flow sensor and hold it down.
5. The No.9 LED turns on and then flashes after approximately five seconds.
6. Release the button, calibration is finished ( lights 0 to 8 permanently on, No.9 flashes)
To avoid to much stopping / starting of lamps due to fluctuations in flow, the
Commutation threshold (red LED) must not exceed No.5, if this is not the case:
1. Press briefly on ◄ or ►, the red LED flashes
2. Press on ◄ or ► as often as necessary to make LED 5 red
The system is now operational. Reset the flow rate to the maximum (close By-Pass).You can switch the
lamps on.
Stop filtration to check that the unit stops within a maximum time limit of approximately 60 seconds. (it
can only be turned back on can after a time delay of 30 minutes).
Correct setting:
