When the ATG is installed in a hazardous area, the technician must work in accordance with the local requirements for electrical equipment in hazardous areas. Closing the compartment covers In order to ensure that the covers open easily, their screw threads have been greased.

Item Name Description CA Calibrate With this command the displacer is pulled up until it is halted against the tank top reference. The tank top level must be set for correct wire weight compensation.

Because of sludge, the enfaf limit switch low must be set on mm. BT Balance test With this command the balance of the measuring drum is checked.

Check whether the gauge type is set correct; if not, change it. Missing optional board, or optional ejraf not well connected in backplane, or optional board defective. A minimum correlation between the reference encoder table and the values read from the actual reference encoder is not achieved. Program frequency 2, measured with test weight of g.

Warning Improper installation of cable glands, conduit or stopping plugs will invalidate the Ex approval of your ATG. Disconnect the mains and transmission cabling from the back-plane!

Instruction manual series 854 ATG level gauge

Instruction manual AlarmScout A In dip mode the displacer is positioned at distance DH above the product and kanual a time atb DT, the product is dipped. Refer to Appendix A for the dimensions of O-rings. Hold the test magnet in front of the display. Close the ball valve.

If the test magnet is hold for more than 8 seconds, a lock test is performed. After the initialisation of the gauge, the displacer is moving down, because the default level setting is at 26 metres. If repeatability deteriorates more than 1 mm the drum bearings should be replaced refer to section 5. Pay attention to the kind of product in the tank.

To avoid oscillations, a certain hysteresis and integration time is software adjustable. A magnetic coupling transfers the drum movement hence, displacer movement to electronic compartment.

The contents, descriptions and specifications are subject to change without enrraf. After opening, grease it lightly with anti seize grease. The default setting is on interface 1 I1. During the test, the level dimension and level type on the display are replaced by exclamation marks!!!

The gauge will now initialize and after start-up, the modified settings become active. The displacer will remain in its position until an unlock command UN is given. Tank top Request for the tank top value, which was established during level calibration.

Refer to section 5. Check whether manometer is suitable for the maximum pressure in the tank. A description preceding the technical procedures gives the technical information necessary to understand its functioning. High level alarm set point. Pull out the drum and fix the wire to the drum with a rubber band. Refer to the installation guide Advanced Technology Gauge. For verification of the level calibration, refer to section 4.

Request for the minimum unbalanced weight. Select gasket that is suitable for flange type, maximum pressure and product to be stored. Displacer weight The weight of the displacer can be measured with the following procedure: When the balance test is ready, the status on the display changes from BT into FR. The shaft of 8554 drum is connected to the stepper motor rnraf a magnetic coupling.

The covers should be turned counter-clockwise until the thread Aclicks in place, then turn clockwise until the covers are fully closed. For more information, refer to the Instruction manual Engauge service tool.

Warning Improper installation of cable glands, conduits or stopping plugs will invalidate the Ex approval of the ATG. FR Freeze Send a freeze command to stop the displacer movement. SM Set maintenance Go into maintenance mode. Do attg open any of the instrument covers while power is still connected. That should be done in this stage.
