1.
Clean both threads from fat.
2.
Brush the male thread at the hose with liquid sealant (e.g. Eurolock 310100 or equivalent selaing of other
manufacturers). Please be careful that no sealing gets into the meter.
3.
Screw both parts together.
Do not overtighten the screw connection, otherwise the swivel of the meter could be damaged.
4.
The instruction of the sealing manufacturer should be absolutely followed.
5.
The meter mounting should only be carried out by authorized specialist staff.
The right selection of the components as well as the mounting in accordance with the regulations is in the responsibility
of the user.
3. Programming and use
LM OG-A (CND)
The units of measure and the correction factor can be programmed. A momentary contact programming button is
located on the bottom of the register, which is accessible only when the register has been removed from the meter.
Removing the register from the meter requires the removal of a sealed register mounting screw. This seal has to be
restamped by the Office of Weights and Measures. Activating the programming button (by pressing it for 3 seconds) will
immediately force the register into the program mode. Any reed switch activity during the program mode will cause the
register to exit from the program mode.
Programming procedure LM OG-A
a)
Upon initial activation of the board mounted program button, the register will display for example:
-
Correction factor = 1,0000 LM OG
= 1,4700 LM OG-HF
-
Unit of measure L
The programmable correction factor has a range of 0,0000 to 9,9999. The decimal point is always located after
the first digit. When “litres” is programmed or selected as the unit of measure, the decimal point will immediately
change to a comma and will remain so as long as “litres” is the selected or programmed unit of measure. (Default
values are 0,0000, “clockwise” and “QT”, if no values have been programmed previously).
b)
The unit of measure indicator in the display will immediately begin flashing at 0,3 second rate, all other display
action being constant, indicating that the unit of measure is available for change. With each depression of the
RESET button, the unit of measure indicator will step through its individual four values in sequence, which are
(QT) – GAL – L – PT.
c)
Depressing the TOTAL button will store the presently displayed data as the current value for the new setting.
d)
Any depression of the RESET button will increment the first or left most digit of the correction factor. Depressing
the TOTAL button will store the presently displayed value as the current value.
e)
This depression of the TOTAL button in step d) will initiate flashing action of the next successive digit in the
correction factor and allow it to be scrolled with the RESET button. All other digits will remain constant. This
successive programming action will be continued for the remaining four digits of the correction factor. The four
right most digits of the correction factor will be allowed to assume the full range of values from zero (0) to nine (9).
Each depression of the TOTAL button will store the value present on the display as the current value for that digit.
f)
Successive depressions of the TOTAL button will continue to enable flashing and scrolling of the digits or unit of
measure in sequence. The action will continue even if a particular unit of measure or correction digit has already
been selected by a previous action.
g)
If no scrolling by the RESET button is undertaken between depressions of the TOTAL button, then the present
value of a digit or unit of measure as displayed will be utilized as the current value for the digit or unit of measure.
h)
Removing pressure from the program button at any time during the programming process will force the values
presently displayed (just entered or previously entered) to be stored as permanent values. The storage of the new
values will be indicated by the entire display flashing three times to acknowledge the process.
i)
During the process of the programming operation as per item h) the seed number in the memory of the mP is
multiplied by the correction factor. The result is the proper batch volume increment which corresponds to one
input pulse. It will be stored as well as the unit of measure with simple redundancy to assure security.
j)
The contents of the totalizer counter will be kept during reprogramming, as long as the unit of measure is not
changed. If programming as described under h) is completed with a new unit of measure, the totalizer counter will
automatically be zeroed. It does not matter if the units of measure have been toggled during the course of the
programming only the final stored value is important.
After release of the program button, the microprocessor will switch off all functions, incl. LCD display, only the
data storage will remain constant. This status will remain unchanged until the RESET or TOTAL button are
pressed. A new depressing of the program button enables a new switch off.
The program button does not work after the microprocessor has been switched off as described above.
