Unit is in digital command mode 2. In such cases pay particular attention to personal protection protective clothing, gloves, glasses etc. Logux source below 3,6 mA 2.

Rotary actuator with spring return and positioner. Incorrect wiring polarity 1. The Logix si positioner controls actuators with linear and rotary mountings.

To exit the local control mode and return to normal operation, briefly press the QuickCal button. Piezo voltage – Bad electronic assembly, replace. To support the Logix the calculated voltage must be greater than The switching point can be set by adjustment of the vane.

During the Quick-Cal operation the valve may stroke unexpectedly. As with all the positioners within the Logix family, the Logix si uses the latest piezo technology with 510is Feedback to produce improved dynamic behavior.


Position Lower – The position has reached or is exceeding a user defined lower travel indicator similar to a limit switch indicator.

The complete control circuit is powered by the two-wire, mA command signal. Maximum cable length or cable impedance exceeded 1.

Observe the minimum requirements of voltage and equivalent electrical load: Switches Figure 11 Install 3 x screws 1 into positioner housing. Tighten all screws and nuts. There is a small black arrow indicating the selection. The D30 is a robust, intelligent positioner with very high air capacity.

Local control of valve position — Can be done loix the user interface by holding both jog buttons and then simultaneously pressing the Quick-Cal button.

Loosen the follower pin and shift it along the follower arm until the control marking on the feedback gear Figure 4 is horizontal points to the center of the feedback potentiometer. Limit switch unit Optional Adjust the signal to the correct range and re-do the calibration.

Maximum torque 0,25 Nm 0,18 ft-lbs. The installation of explosion proof electrical equipment must comply with the procedures contained in the certificates of conformance. Don’t show me this message again. 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.


Got it, continue to print. Switches Enabled The Logix si will read all of the configuration switches each time a Quick-Cal is performed to determine the configuration. 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. The piezo valve-based electro-pneumatic converter module 3. Control tuning parameters not correct 3. Fit and check O-rings and positioner to actuator and secure with 2 x screws 3.

Principle of operation The Logix si positioner is a digital positioner with various options. 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.
