Notify proper personnel that the valve will stroke, and make sure the valve is that the Logix si is only logi internal gain and properly isolated. Check linkages and air supply to make sure the system is properlyconnected.

A slight unsymmetrical mounting increases the linearity deviation but does not affect the performance of the device. This means that changes to the switch logiz while the positioner is in normal operation will have immediate effect on the control algorithm. If the length of rotation is outside the control markings, adjust the follower pin farther out on the feedback lever to reduce the angle of rotation.

The follower pin should point back from the positioner. The basic positioner operation is best understood by referring to figure 1. Note a factory reset is the only method to reset the command back to analog control mode from the local interface if a PC or handheld configurator is not available.

Check that logux follower pin is inserted in the slot of the take-off arm and the follower arm is positioned at a right angle to the outer edge of the positioner.

Version Number Checking Logix si Status Condition Codes Colors Identifier Indication and resolution R – – – Any sequence starting with a red light indicates that there is an operational problem with the unit.

Attach the positioner to the pre-assembled mounting bracket and fasten it with two hexagon head screws and two lock washers.

When the valve actuator is at the desired position.

See the appendix for an explanation of the various light sequences. Three colored LED indicators continuously indicate the positioner status.

Feedback saturated – Calibration error indicating that the position sensor was out of range during the calibration. With a maximum supply pressure of 6 bar psi a logi is not required. In such cases pay particular attention to personal protection protective clothing, gloves, glasses etc. According to EU legislation, this product must be recovered for separation of materials and may not be disposed of as unsorted municipal waste.

Digital command mode – The analog mA input signal is ignored in this mode and a handheld or Flowserve supplied software is needed to change the position command.

It can stand alone or be integrated into a system, and is available for a variety of applications including oil and gas, chemical, paper, mining, industrial gases and power generation. In general, shield wire should be connected at the source. Logix si positioner accessories: Fit and check O-rings and positioner to actuator and secure with 2 x screws 2. If the positioner still does not operate replace the pneumatic relay assembly.


Incorrect wiring polarity 1. Table of Contents Add to my manuals Add.

This two-stage control provides for more responsive and tighter control than is possible with a single stage control algorithm. Current source below 3,6 mA 2. On Enables an auto tune feature that will automatically determine the positioner gain settings every time a QuickCal is performed based on the setting of the lgix Gain switch.

See detailed instructions in section Comments to this Manuals Your Name. Actuator tubing backward 5. The Logix si digital positioner can be equipped with an additional limit switch unit. The D30 is a robust, intelligent positioner with very high air capacity. This error may be cleared by briefly pushing the Quick-Cal button, which will force the positioner to use the parameters from the last good calibration.

If the Config-Switches option is enabled, the settings of all the configuration switches are read and the operation of the positioner adjusted accordingly. The piezo valve-based electro-pneumatic converter module 3. Optional analog feedback system as well as limit switch unit and a directly attachable double acting module.
