Remove the drum compartment cover rear cover.
Simple audit trail functionality is implemented by recording several SAT related parameters. Manuap declaration of conformity Refer to the EC declaration of conformity, shipped with the instrument.
Legal aspects The information in this manual is copyright property of Enraf B. Some of the data items are read-only. The difference between both immersion depths must be given in item L3 Example: The maximum operating level is The dip mode is cancelled when one of the interface measurements is selected.
Data requests Items for tag of setup or measuring data from the gauge. In dip mode, the displacer is raised above the product over the dip height distance DH.
Instruction manual series ATG level gauge
Secure this end several times around the hook Figure 3. Remove the displacer from the measuring wire.
Check the connections of all electrical cabling. Item Name Description CA Calibrate With this command the displacer is pulled up until it is halted against the tank top reference.
The wire tension has been too low for a while. These switches can be operated by holding a magnet in front of them not the test magnet! Bytes 0, 1 and 2 are bit coded with information about the level alarms, operational mode and general status. Use screwdriver for Allen key screws M4 item 8 of the Honeywell Enraf tool set.

If one of the other two interface measurements is selected, the gauge will remain on that interface measurement till the default measurement I1 is selected. Check the span wire. EX Exit Exit protection level. If the ATG is installed in a hazardous area, threaded rigid metal conduit or threaded steel intermediate metal conduit shall be used. If a density displacer is used, check whether the engraved weight is programmed correctly in this mnaual.
That can be calculated as follows refer to figure 3.
The standard displacers have a weight of g. The display will show a BL block or FR freeze in the lower right corner of the display. Bring the drum in a slight vibration. Safety Page 10 2. In dip mode, the interval time for the dip is specified in the dip time interval DT. A magnetic coupling transfers the drum movement hence, displacer movement to electronic compartment. The high and low level alarms are innage alarms. After the first command, use the key and enter key.
RL Reference level Request for the reference level value, which was established during calibration. Open the ball valve. Wrong data field length, check for correct item setting. Item not known to ATG, check for correct item. If a density displacer is used, check whether the engraved weight is programmed correctly in this item.
Enrraf the XPU detects an error about a certain item, that item follows the error code, separated by a space. For the dip mode, items DH and DT have to be set checked during commissioning or at a later stage: Use non-sparking tools and explosion proof testers. After the interface has been measured, the displacer will be raised over the dip height DH. If any danger for health, wear a gas mask and take all necessary precautions.
Knowing the volume of the displacer, its weight in air, and the measured apparent weight, the relative density of the product at each position of the displacer can be calculated.
The drum shaft bushing is kept in position by a circlip.

Immediately after power on the display is blank. CA Calibrate With this command the displacer is pulled up until it is halted against the tank top reference. Two carbon PTFE bearings in the drum shaft bushing support the drum aatg. On tank is the nozzle height For high pressure version max.

This measurement takes approximately 5 minutes. The default behaviour of the SAT can be influenced by means of a number of configuration items. The design of the ATG is such that it makes replacement and service simple.
