Synchronizing The Reference Encoder - Honeywell 854 ATG Series Instruction Manual

Do not yet reprogram this value in the gauge. Reprogram all values after completion of all the four calibration
measurements. Repeat this calibration from item BT for the other 3 test weight combinations:
• for F1 with: (25+75 g),
• for F2 with: (25+150 g),
• for F3 with: (25+225 g).
Remove the test weights from the measuring wire and attach the displacer.
Program the measured frequencies :
Item Name
W2= Protection level 2
F0= Frequency constant 0
F1= Frequency constant 1
F2= Frequency constant 2
F3= Frequency constant 3
WT= Wire rupture
EX Exit
Note:
A faster method of calibration is using the commands MF and FQ in stead of BT and BF. This method
may not be followed when your gauge is used for density measurement via the density displacer.

5.6 Synchronizing the reference encoder

After the installation of a new motor block or in case of mounting new software, the internal reference
encoder must be synchronized to the position of the reference encoder and the gauge starts with an error
code e.g. ES553 / ES555. The following procedure will do.
Item Name Description
W2= Protection level 2
SM Set maintenance
FP Find position
SO Set operational
EX Exit
The gauge is now ready for level calibration (refer to section 3.4).
