c. Enter the BASIC SETUP menu to display [COUPLNG:%]. d. Look through the side orifice and verify that the screw (62) coupling end of the beam (54) is loose and that the spring arm (242) is disengaged from the pin (243). Through the 3/4 ” NPT hole at the bottom of the case, push the flexure (59) from left to right with your finger to verify it is possible to move the beam (54).
In case of failsafe signal use ([FAIL LOW] or [FAIL HIGH]), check that loop current variations are in line with process and safety rules implemented into the Distributed Control System. ♦ See Appendixes A to G which describe operating and setting menus. 24 | GE Oil & Gas ® 2014 General Electric Company.

7.3. TRANSMITTER CALIBRATION 7.3.1. O PERATING RULES AND CALIBRATION PRINCIPLE The purpose of this chapter is to detail internal device operating rules to understand names of functions and describe actions generated by the embedded firmware during calibration. Advanced settings are also described to answer user constraints. In some cases, the user can avoid doing a new calibration following a process change or can enable a level measurement on a specific range different than the standard one.
The level indication corresponding to REF H is set through function [URV] via [VAR SET]; it is expressed in the unit set through [UNIT] function; if UNIT is "%", [URV] must be 100.00%. 26 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
♦ Calibration of transmitter for interface application: The level transmitter is used to measure the interface level of two immiscible liquids of different specific gravities. The displacer must always be fully immersed. The electronic circuit is calibrated towards two reference levels (REF L and REF H). See schematic below. REF L corresponds to the displacer completely immersed in the liquid of Lower Specific Gravity used for calibration [LSG ...
Enter and validate the [ZERO]: the [LEVEL:%] value indicated on the display must equal to 0.0%. If not, restart the procedure until very close to this value. See Appendix B. 28 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
d. High Level [SPAN] d1. Liquid application: Attach to the torque arm a set of weights equivalent to the apparent weight of the displacer fully immersed in the calibration fluid with Specific Gravity of Calibration [SG CALIB], i.e.: Displacer Apparent Weight for REF H = Displacer Actual Weight - (Displacer Actual Volume X [SG CALIB]) i.e.
7.3.4. C ALIBRATION WITH MECHANICAL STOPS CAUTION: This procedure is only possible if mechanical stops (adjusting screws) have been previosuly adjusted upon process fluids. See mechanical stops setting Section 7.5. This calibration procedure is very useful on site and for interface application when there is no capability to make level variations into the tank.
See Appendix B. h. Press the * button when [SAVE] is displayed to validate the [ZERO] and [SPAN] settings. Reinstall all plugs (107), (190), and (115). 32 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
7.4. CALIBRATION OF SPECIFIC GRAVITY METER This adjustment is made at the factory for complete instruments. The specific gravity function [SG METER] is very useful in performing on site new calibrations, simulations with or without liquid and direct reading of specific gravity of liquids on the application.
Press the flexure (59) against the adjusting screw shoulder (114), which corresponds to the lowest specific gravity [LSG CALIB]. While maintaining contact and using a 3 mm hex wrench, turn the adjusting screw until LCD displays this specific gravity. 34 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
[SPAN] IGH LEVEL REFERENCE f1. Liquid application: Press the flexure (59) against the adjusting screw shoulder (114) which corresponds to the high level (on displacer side). While maintaining contact and using a 3 mm hex wrench, turn the adjusting screw until LCD displays the value of process specific gravity [SG CALIB].
To define the expected process temperature, click the Process Temperature checkbox and enter the corresponding temperature value in degC. d. Validate by clicking on Apply. 36 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
7.6.2. T EMPERATURE COMPENSATION SETTING Through ValVue suite software, the temperature compensation parameters can be set on the Advanced Setup menu. a. On the Advanced Setup tab, click on Database. b. Click on the arrow of the drop down list, located at the right of the Torque Tube Matl. c.
7.7.2. C ONTROLLER ACTIVATION The activation of the controller function can be performed in the Advanced Setup menu trough the push-buttons or ValVue suite software only. 38 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
Activation through push-buttons (see Annex C): a. Change device mode to Setup mode and go to the Advanced Setup menu. b. By pressing two times the push-buttons +, go the Controller (CTRL) menu and press * to enter. c. Activate or disable the Controller function. d.
These two parameters are automatically calculated to convert controller setpoint range Ratio Gain and Ration Bias (%) and units into level measurement range and units. 40 | GE Oil & Gas ® 2014 General Electric Company. All rights reserved.
188.8.131.52. Controller configuration Click either Direct or Reverse. Direct action means that the 4-20mA controller output increases when the process variable is greater than the setpoint when process variable (is Controller Action lower than setpoint for Reverse action). Click either PV or Error. This determines whether calculations are based on process variable Derivative Source or error.
This screen allows to change the 4-20mA output signal (when in MANUAL mode) by dragging the controller output indicator or entering a detailed value, or to change the process setpoint (in AUTO mode) by dragging the setpoint indicator (right bargraph) or entering a specific value. 42 | GE Oil & Gas ® 2014 General Electric Company.

9.4. MOUNTING OF DLT CASE AND TORQUE TUBE SUB-ASSEMBLY (FIGURE 24) CAUTION: The following procedure is valid only if the coupling between beam and torque rod has already been adjusted for the required mounting direction (see Section 7.1). The case mounting direction for which the coupling has been made may be identified as follows: When the case is mounted and coupled to the torque tube (without torque arm or displacer), the tip of the conical pin (53) is aligned with one side of the oval hole in the flexure (59).
Replacement of the main electronic module, terminal board, sensor S/A or mechanism S/A must be performed using high accuracy tools and requires the instrument head to be returned to a GE’s Operations. If the actions done according to Section 10 failed to correct a default, please contact our local After-Sales Department.
