LOGIX 510SI PDF
LOGIX si OVERVIEW. The Logix si is a two-wire, mA input digital valve positioner. The Logix si positioner controls single-acting actuators with . Mounting of the Logix si Positioner on a Linear Pneumatic Actuator. ( NAMUR / IEC document describes the setting and use of the Logix si. Available Logix + Models. Part of the versatile Logix positioner series the Logix + and Logix + digital positioners fulfill the ever growing.

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. The switching point can be set by adjustment of the vane. If necessary, they logox easily accessible for cleaning. As the valve approaches the desired position, the difference between the commanded position and the measured position becomes smaller and the output to the piezo is decreased.
Mounting the Follower Arm Figures 3 and 6 1.
POSITIONER TYP LOGIX 510SI
Check linkages and air supply to make sure the system is properlyconnected. 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.
Never connect a voltage source directly across the positioner terminals. Normally this will be 4 mA, but if split range operation is required use the minimum current for the desired operating range. Don’t show me this message again.
Normally this will be 20 mA, but if split range operation is required use the maximum current for the desired range. For connecting the air piping, the following notes should be observed: If the length of rotation is outside the control markings, adjust the follower pin farther out 501si the feedback lever to reduce the angle of rotation. Pressing and holding the Quick-Cal button for approximately three seconds will initiate the calibration.
Move the positioner to second switching position LS2. The Gain Selector switch is also read and action will be taken to adjust the gain according to the settings of the calibration switches as described in the previous section. Hall sensor upper position – Check to make sure the air supply is connected.
The grounding screw, located inside the positioner cover, should be used to provide the unit with an adequate and reliable earth ground reference. The input loop current signal to the Logix si should be in shielded cable.
To adjust switches Loosen 2 x screws on top of cam assembly, rotate cams to desired switching position. For units installed in Hazardous areas special 51s0i caution and procedure is required. Position Upper 510di The position has reached or is exceeding a user defined upper travel indicator similar to a limit switch indicator.
The pneumatic amplifier controls the airflow to the actuator. Error occurred during calibration 1. Mounting the positioner Figure 3 1. Press the simultaneously to put the unit back inoperation. The air supply must conform to ISA 7.

510xi and grounding guidelines The Logix si positioner can be used with: Tighten all screws and nuts. On Enables an auto tune feature that will automatically determine the positioner gain settings every time a QuickCal is performed based on 51si setting of the pogix Gain switch. To control cable resistance, No. This pause and buttons allows the signal to be adjusted without affecting the valve position.
Note that the valve will be locked at its position when an input loop calibration is initiated until the calibration is completed.
The infinite resolution valve position sensor. An electromagnetic line filter can be used to further eliminate noise. Indicator cover flat assy.
With this setting a QuickCal only zeros and spans the positioner. Feedback span – The range of motion of the position feedback arm was too small.
Position Deviation logx The position has exceeded user defined error band between command and position. To clear the condition use handheld or Flowserve supplied software to reset the indicator if more travel is needed or adjust the command signal back in the specified range. Enter text from picture: As with all the positioners within the Logix family, the Logix si uses the 510ssi piezo technology with Inner-Loop Feedback to produce improved dynamic behavior. Shipping weights Shipping weights with pressure gauges: Settings A through H are progressively higher gain predefined tuning sets.
A QuickCal can be aborted at any time by briefly pressing the Quick-Cal button and the logi settings will be retained. Table of Contents Add to my manuals Add. Optional analog feedback system as well as limit switch unit and a directly attachable double acting module. Standard globe valve or equivalent Actuator: Verify hardware connections 3.
