EMERSON FX-208 DRIVE drives available from stock

Description

The mechanical bias FX-208 adjustment of the servo valve can affect the results of on-board

diagnostics. A set-screw on the servo valve causes a deflflection from center position

of the servo valve spool. This allows hydraulic flfluid to escape the actuator, and the

valve to close at controlled rate, in the absence of an electrical signal.

For a typical hookup, a small negative voltage on the servo valve is required to

center the spool, and hold the valve in a steady position. This FX-208 voltage is typically

from -100 to -300 mV. Servo valves are delivered from the factory with this

adjustment. On board diagnostics assume that the servo valve is set up in this way.

If another setup is used, program the Ovation Controller to ignore the results of

diagnostic bits.

Calibration can be performed by using the Valve Positioner Upload/Download/

Calibrate graphic (diagram 8719) to view FX-208 and modify the VP tuning constants. All

the constants can be modifified. The 0% and 100% calibration values, and

demodulator gain, can be determined by the calibration sequence, and can be

adjusted by the user with this graphic.

The graphic has upload/download buttons so that the two sets of numbers can be

synchronized (made the same). This FX-208 synchronization is initiated by the user and is

the responsibility of the user. In addition to the constants, there are four fifields that

provide operator feedback.

The constants exist in two places:

• EE memory on the Valve Positioner module.
• In the VPSTATUS algorithm record (typically, the constants contained in the

algorithm record are considered as the master set).

If an VP module fails and is replaced, the user simply downloads the constants to

the new VP and it is ready to operate. The constants are not automatically copied to

the algorithm record upon completion of a calibration sequence.
