Item Name Description
W2 = Protection level 2 Enter protection level 2 (default password: ENRAF2)
TT = Tank top Format according to item LD . The tank top level must be set for
correct wire weight compensation. The value you enter now, is
overwritten when the level calibration with displacer stop is used.
MH = Motor limit switch high Format according to item LD . This is the highest allowed position for
the displacer during normal operation.
MZ = Lock test limit switch level Format according to item LD . Item MZ sets the highest displacer
position during a lock test.
ML = Motor limit switch low Format according to item LD . This is the lowest allowed position for
the displacer during normal operation.
DC Drum circumference Standard floating point format; units: metres.
Check whether the pre-programmed drum circumference is in
accordance with the engraved value of the installed measuring drum.
If that is not correct, enter the engraved drum circumference.
DW Displacer weight Standard floating point format; unit: grams. The standard displacers
have a weight of 223 g. If a density displacer is used, check whether
the engraved weight is programmed correctly in this item. If not, then
enter the engraved displacer weight.
DA Displacer area Standard floating point format; units: cm
2
.
Check whether the pre-programmed displacer area is in accordance
with the used type of displacer. Refer to Appendix B for information on
the displacer area values. If not correct, program the correct displacer
area.
S1 Set point Standard floating point format; units: grams. With the standard
displacers, the interface 1 set point (level surface) is set to 208 g.
If a density displacer is used, program
S1 as: ( DW - 15).
TA = Transmission address Two digits. The transmission address identifies the gauge on the
Honeywell Enraf 2-wire field bus. Each gauge must have a unique
address, and hence
TA must be programmed differently. When
connected to an 858 CIU, please note that the 858 CIU has three
highways, containing the following transmission addresses:
CIU highway Transmission address ( TA )
TL 1 00 - 29
TL 2 30 - 59
TL 3 60 - 99
TI = Tank identifier Six characters. Used as a label; the tank name can be programmed in
the tank identifier item (spaces are not allowed!).
TS = Transmission speed Four digits; either 1200 (default) or 2400. Units: baud
GT = Gauge type One character. Represents the gauge type. For the 854 ATG, GT=B.
EX Exit Exit protection level 2. The gauge will now initialize and after start-up,
the modified settings become active.
