CE4003S2B6 Emerson AI controller module

Description

Rapid or CE4003S2B6 erratic valve movement can damage the turbine. The Valve Positioner

enforces a set of rules to accomplish bumpless transfer between modes. The

description of each mode includes mode transfer.

When the Valve Positioner is powered-up or restarted, its primary objective is to

avoid an indeterminate output that would CE4003S2B6 result in valve movement, and possible

damage to the valve or turbine. There are a number of hardware and software

features that prevent an indeterminate output.

The hardware is designed so CE4003S2B6 that when the Valve Positioner is powered-up, the

power supply to the servo output is turned off. With no current flflow to the servo

valve, it is left under the inflfluence of its mechanical bias adjustment, the assumed

state prior to power-up. In addition, the coil drive D/A convertor is not turned on

until it receives the fifirst output pattern.

As part of the microcontroller’s start sequence, the power supply is turned on, and

then a pattern is written to the CE4003S2B6 coil drive D/A convertor representing 0 volts. The

result is that the servo output is under software control, no current flflows between

the Valve Positioner and the servo valve, and no valve movement has occurred.

The Valve Positioner will not remain in Start mode unless a diagnostic error is

detected. The Valve Positioner transitions from Start to Local mode if all of the

following functions execute and return “normal” or “ok” status codes:

• Program the FPGA.
• Go to Factory Confifigure Mode if PE pin is 1.
• Check PE pin. Go to Factory Test Mode, if required.
• EPROM checksum check.
• EEPROM checksum CE4003S2B6 check.
• RAM read/write test.
• D/A convertor readback diagnostic.
• UART scratchpad read/write test.
• Shared memory readback check.

The Valve Positioner will set target valve demand equal to demand feedback before

transferring to Local mode.
