Note:
As shown in this example, the MCI screens loop around, like the telephone call list
on a cell phone. It is sometimes easier to move in the opposite direction to reach an
item at the end of the loop.

2.13 Calibrate my Sensors
!
Calibration of all sensors is performed at the factory and at the start up of the pump station by your
FlowNet service technician.
!
!
Note:
Calibration by the end user should only be required if a sensor is replaced with a
different sensor, or damage to the PLC program occurred. The end user is
encouraged to call their FlowNet office for this service rather than attempting
themselves.

All sensors are assigned to channels—the major channel assignments are as follows:

· On a station with one flow meter, channel 2 is the flow.
!
· On dual zone stations, the flow meter for zone 1 is on channel 5, and the flow meter for zone 2 is
on channel 6. Channel 2 totals the two zones.
!
· On triple zone stations, the flow meter for zone 1 is on channel 5, and the flow meter for zone 2 is
on channel 6, and the flow meter for zone 3 is on channel 7. Channel 2 totals the three zones.
