Drum should be transported in original protective box. Tank identifier programmed as Ehraf After replacement of force transducer or motor block the force transducer requires re-calibration refer to section 5. Pull out the drum and fix the wire to the drum with a rubber band. Attach the smallest of the four test weights or another small weight to the measuring wire, remove the rubber band securing the measuring wire and feed the wire and test weight through the neck of the gauge see figure 3.

Tank top is The sequence of steps in a procedure may also be important from the point of view of personal safety and prevention of damage; it is therefore advised not to change the sequence of procedure steps or modify any procedure in any other way. Execution of enrf that are not prescribed;!
Be aware that measuring wire is unrolled from the measuring drum. Warning Improper installation of cable glands, conduits or stopping plugs Will invalidate the Ex approval of the ATG.

UN Unlock Give an unlock command to cancel the calibrate 8544. The weight of the ATG for: Repeatability test refer to section 4. Correct, if necessary temporarily the motor limit high setting MH, in such a way that the gauge will automatically return to this level after a lock-test command LT.
The floating point format is a fixed format;!
RL Reference level Request for the reference level value, which was established during calibration. Lock test limit switch level is set between maximum operating level and MH. Check the connections of all electrical cabling. An Honeywell Enraf tank adapter can be provided with such a facility. Unlock Give an unlock command to cancel the calibrate command.

The floating point format is a fixed format; Standard floating point format: BV Minimum unbalanced weight Standard floating point format; units: Jumper setting changed while power was on. Caution Keep screw threads free from dirt.
To prevent other commands in the initialization sequence, the Honeywell Enraf field bus lines may, temporary, be disconnected. The stepper motor turns one revolution for every 10 mm of vertical movement of the displacer.
Item BM has to be set checked at commissioning or at a later stage: Hence a high alarm condition occurs when there is a low ullage value and visa verse. Take an extra piece of wire and fasten one end to the measuring wire, pass the other end through the hole in the end of the displacer hook. Attach a small weight on the kanual to keep it positioned qtg the groove. It is ready when the status on the display changes from MF into FR.
If also pressure transmitters are connected, use a junction box for parallel connection of the pressure transmitters and water bottom probe. S1 Check whether the set point 1 is set correct; if not, change it. CA Calibrate The displacer will now raise from the enrav valve. The resulting difference between measured and desired value will cause a variation in the position of the stepper motor and consequently raise or lower the position of the displacer until the measured value equals the desired value.
Check whether the displacer weight is correct; if not, change it. When the repeatability test is completed, the selected level manua and level type appears and TG is replaced by I1.
