LM_OG_BA_98_1803
During the self test period, the meter will compare the double redundant storage of
the correction factor, the unit of measure and direction of rotation. If one of the values
do not correspond, the register will show a series of dashes (- - - -) and will become
inoperative.
If flow sensing or reed switch action is present at any time and it is not preceded by a
pressing of the RESET button, the flow accumulations will be added to the value
already present in the batch accumulator.
9.6 Totalizer
The total dispense quantity is shown in the bottom line. The factory programmed
correction factor results from accuracy testing of bare meter with the mounted
electronic register: Pressing the TOTAL and the RESET button simultaneously for 3
seconds will show the programmed correction factor.
Resettable totalizer: 999,999 L (over thousand 9999,99 L)
Non resettable totalizer: 99999 L
As soon as volume signals come in, all keyboard commands will be ignored!
As soon as pulses are internally accumulated, the keypad is out of function!
9.7 Monitoring of false pulses for MID conform meters
During measurement, the microprocessor controls the phase position of both reed
switches (30° to 150° phase shift).
Errors caused by incorrect phase sequence:
If more than two (2) phase errors are noted after a RESET, the LCD display is
flashing (1 second interval). This type of error is resettable by depressing the RESET
button.
If it is not possible to stop the flashing, there is another fault and the register has to
be exchanged.
The flashing can e. g. also be caused by a short-time reverse flow when starting up
the oil dispense system, or by an insufficiently aerated oil pipe (pressure shocks).
This can be prevented by installing an appropriate non-return valve.
FLDIR will indicate a reverse flow, quantity display will change to ---,--
REED will indicate a missing input channel, quantity display will change to ---,--
Errors in stored variables: (i.e. correction factor, unit of measure, direction of rotation)
These errors are indicated by a series of dashes across the display and are not
resettable. The register has to be removed from service.
9.8 Installation procedure LM OG
The meter series LM OG is equipped with BSP female threads. In order to obtain a
leakage-free connection from the meter to the hose, the hose end must have an
appropriate BSP male thread.
We recommend to proceed as follows before screwing in:
1. Clean both threads from fat.
2. Brush the male thread at the hose with liquid sealant (e.g. Eurolock 310100 or
equivalent sealing of other manufacturers). 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
