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!
Monitoring of False Pulses for MID Conforming Meters
During measurement, the microprocessor controls the phase position of both reed switches (30…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 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:
(That is, 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 .
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 (for example, 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 .
