UCD208A101 3BHE020018R0101 Analog module

When the RSR is seating the valve, then decides to retreat, this is the output in mV to which the output goes. exitBkSeatVal=-5000 When the RSR is backseating the valve, then decides to retreat, this is the output in mV to which the output goes. CASCADE=0 If this flag is set to 1, the two PI’s are cascaded.Make the following changes to Table 22-11 “Servo Driver Diagnostic”: For LED E (Red) Description, delete the following Possible causes: “SLIM not connected,” and “No auxiliary voltage,” For LED I (Red), delete the following: “Fatal error occurs Added support for the following:
Calibration from the Controller using graphics.
Upload/download of calibration constants to and from the Controller.
New tuning constants kServo and kServoDb to replace hard-coded constants. They add flexibility in dealing with differing coil impedances.
Reduction of valve calibration time.Redundancy support changed so that multiple failovers are precluded. Improvements to calibration. Fixed problem with coil diagnostics for “coilCount = 0”. Position feedbacks rollover problem fixed.

Shutdown Input (Priority Demand Input) 

For VP firmware revisions 0H and later, the shutdown input is redefined to “Priority Demand Input”. When the input is activated, the target position is set to a tunable constant. For compatibility with previous firmware revisions, the default value of priorityDemand is -5%. This allows the user to rapidly move the valve to some intermediate position during upset conditions. The user has the flexibility to create his own scheme to handle an upset. While the “priority demand input”, or “Shutdown” input is active, the VP is in the local mode and the controller must unconditionally track demand feedback. Page 25-29, Section 25-10.5. “Open Coil Diagnostic Error”, replace “is incorrect” at the end of the second sentence with: has been adjusted to yield that result.

add the following text after the first paragraph of the section:

 For firmware revisions prior to 0F, the diagnostic works as described below. For later revisions servo coil voltage is measured and compared to a model described by tuning constants “kServo” and “kServoDb’. If the voltage does not fit into the model, due to being too large, “open coil” is blamed and the internal diagnostic bit is set. Then the timing sequence described below is used to post the error bit to the controller. Page 25-30, Section 25-10.6. “Shorted Coil Diagnostic”, add the following text after the first paragraph: For firmware revisions prior to 0F, the diagnostic works as described below. For later revisions servo coil voltage is measured and compared to a model described by tuning constants “kServo” and “kServoDb”. If the voltage does not fit into the model, due to being too large, “open coil” is blamed and the internal diagnostic bit is set. Then the timing sequence described below is used to post the error bit to the controller.
