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.

Principle of 510di The Logix si positioner is a digital positioner with various options. Wiring The voltage 12,5 V is greater than the ligix 6. A coalescing air filter is recommended for all applications due to the close tolerances in the positioner. Don’t show me this message again. Attach the stem clamp bracket to the stem clamp and fasten it with two hexagon socket screws and lock washers. Page 13 Logix si Status Condition Codes Colors Identifier Indication and resolution Y – – – Any sequence starting with a yellow light indicates that the unit is in a special calibration or test mode, or that there was a calibration problem.
Electronic module mA feedback assy Indicator flat assy.
Logix si series Digital Positioners Operation Maintenance
Normally this will be 20 mA, but if split range operation is required use the maximum current for the desired range. Piezo voltage – Bad electronic assembly, replace. For cable runs longer than this, No. To control cable resistance, No.
The air supply must conform to ISA 7. No errors, alerts, or logkx and the unit is in analog control mode. Input loop calibration A loop calibration, requiring an external current source, will be started when the Loop calibration button is pressed with a small object with the switch in the Input position. Feedback span – The range of motion of the position feedback arm was too small. The Logix si positioner controls not to be confused with operating range.
The positioner is preset to Autotune – On at the factory. For more information please see the following guides: 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. To clear the condition use handheld or Flowserve supplied software to reset the MPC if the range is incorrect or adjust the command signal above the specified MPC value.
See the appendix for an explanation of the various light sequences. Notify proper personnel that the valve will stroke, and make logid the valve is properly isolated. Set the switching point of the limit switch by adjusting the lower arm of the lower logiix LS2. A factory reset will always reset the command source to analog mA.
Hall sensor upper position – Check to make sure the air supply is connected. With a maximum supply pressure of 6 bar psi a regulator is not required.
Flowserve Logix 510si Installation, Operation & Maintenance Instructions Manual
To clear the condition use handheld or Flowserve supplied software to reset the limit if more travel is needed or adjust the command signal back in the specified range. Maximum torque 0,25 Nm 0,18 ft-lbs. The Logix si positioner controls actuators with linear and rotary mountings. Page of 16 Go.
The Auto-tune procedure cycles the actuator to produce a measured logux and selects gain values that provide appropriate actuator performance. Positioner operation with limited voltage only.

Lower proportional gain settings 25 This two-stage control provides for more responsive and tighter logid than is possible with a single stage control algorithm. Mounting the Follower Arm Figures 3 and 6 1. 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.
This is the recomended setting. Apart from the operating instructions and the obligatory accident prevention directives valid in the country llgix use, all recognised regulations for safety and good engineering practices must be followed.
Tubing positioner to actuator After mounting has been completed, tube the positioner to the actuator using the appropriate compression lobix connectors: This means that changes to loix switch position while the positioner is in normal operation will have immediate effect on the control algorithm.
If an elevated zero is needed a handheld or other PC based configuration software is required. Signature test in progress – This is a test initiated by Flowserve supplied software that can only be cancelled by that software.
Figure 8 The Logix si digital positioner has been designed to operate correctly in electromagnetic EM fields found in typical industrial environments.
RRYY Bad electronic assembly – replace. It offers excellent control at an affordable price. Soft Stop Lower – The unit is being commanded to exceed a user defined lower travel limit and the internal software is holding the position at the limit. An electromagnetic line filter can be used to further eliminate noise. This pause and buttons allows the signal to be adjusted without affecting the valve 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.
The Logix si positioner can be used with:
