Details of unit operation LM OG-AM MID conform
9.1 RESET button
The display of the resettable totalizer (batch register) can be put to zero by pushing
the RESET button. A RESET is not possible during a batch process.
The RESET of the non-resettable totalizer is only possible in the MID secured area of
the register configuration.
Each RESET will save the dispensed quantity in the datalogger, but only if the
quantity is equal or bigger than 0,5 liter.
9.2 Datalogger: A non-volatile memory
The register is fitted with a memory device to store measurement results until their
use or to keep a record of commercial transactions, providing proof in the event of a
dispute. Devices used to read stored information are considered as included in the
memory devices. It is not required that the parties interested in a transaction shall be
provided continuously with the results of measurement, but only that they shall have
access to these results (for example, in the event of a dispute). In addition, in the
case of self-service (filling station, truck filling station) the owner of the measuring
system is considered to have access to the indications of the measuring system even
when he does not use this possibility in practice (OIML R117-1, Chapter 3.5).
9.3 Battery
As soon as the capacity of the battery is less than 10 %, “LBat” is displayed on the
electronic register. The battery should then be replaced within the next two months.
The battery is exchangeable in all meters of the LM OG-AM and OG-TAERM series
while opening the cover on the front of the register. No data are lost, they are
securely saved in an EEPROM memory - except of the date and time. To keep the
date and time settings, you have to
reinsert the battery within 30 minutes.
9.4 Interruptions of batch process
By releasing the meter trigger, the batch process is interrupted. When pulled again,
the batch process will be continued at the very point where it was interrupted, unless
the RESET button has been pushed in the meantime. The display will remain
unchanged during the interruption. If the batch process is interrupted by external
source – e.g. failure of a transfer pump – the procedure is the same.
9.5 Functional control
In normal operation, the register board totalizes flow in the lube meter by sensing
reed switch actions. The batch display may be reset to zero by momentarily pressing
the RESET button on the front panel. This action will set the batch accumulator to
zero and cause the register to enter a self test mode. For the self test, it is necessary
that the display is activated with all numerics set to “8” and all other indicators set to
“on” for a period of 0,8 seconds. If flow or reed switch action takes place during the
self test period, the resultant pulses are processed as normal flow accumulations.
This accumulation of flow can only be reset by pressing the RESET button.
