FY301 – Operation, Maintenance and Instructions Manual
5.6
5. Verify the pilot chamber pressure measured in the correspondent FYCAL gauge. The pressure
must be between 5.8 and 6.2 psi. In case it is different, made the adjustment rotating the superior
disc of piezoelectric base set;
6. Once reached the previous adjustment, apply 0 Volts again and verify that the pressure in the
pilot chamber must be between 2 psi. After that, apply 100 Volts and verify that the pressure must
be between 12 and 13 psi;
7. Apply 50 Volts AC to the piezoelectric base. Verify the pilot chamber pressure measured in
manometer, it must be between 5.8 and 6.2 psi. In case it is different, made the adjustment again
and rotating the superior disc of piezoelectric base set and repeating the procedure, to reach the
specified values.
8. When these values are reached, the piezoelectric base calibrated;
9. After the piezoelectric base calibration, proceed with the positioner final checking;
10. Re-assembly all positioner set with the calibrated piezoelectric base;
11. Execute the auto-setup for the positioner;
12. If the piezoelectric base voltage is not at indicated range, it means that the piezoelectric base
needs a new calibration or it needs to be replaced.
Restriction Cleaning Procedure
The air flows to the nozzle through a restriction. Verify the restriction cleaning from time to time to
assure a positioner good performance.
1. Be sure that the air supply is not pressurizing the equipment.
2. With an appropriate tool, remove the transducer serial number plate. (New models have the
plate placed on the opposite side of the transducer).
3. Remove the restriction screw using an adequate tool;
