What to do if Ecolab LMI 02 Measuring Instruments show no metering despite concentration undercut?
If there is no metering despite concentration undercut, check the metering enable connection on the instrument and system. Also, verify that the rated value setting is correct, the product storage container is not empty, and the max. metering time has not expired.
Why does my Ecolab LMI 02 Measuring Instruments display 'LOW TEMPERATURE'?
The 'LOW TEMPERATURE' alarm appears when the wash tank temperature drops below the preset limit and the alarm delay time expires. To resolve this, check the heating device. Additionally, you may need to change the temperature limit or the alarm delay time if necessary.
What does 'NO DETERGENT CHECK METERING' mean on Ecolab LMI 02?
The 'NO DETERGENT CHECK METERING' message indicates a potential issue with detergent metering. This can be caused by the alarm delay time t max. (DETERGENT DELAY TIME) being set too short or a defective metering pump. Try changing the alarm delay time or checking the metering pump.
What to do if Ecolab LMI 02 says 'NO DETERGENT CHANGE CONTAINER'?
If the Ecolab Measuring Instruments display 'NO DETERGENT CHANGE CONTAINER', it means the detergent storage unit is empty, or there's a defect with the suction lance or connection cable. Connect a new container or replace the suction lance to resolve the issue.
How to fix instable conductivity display on Ecolab LMI 02?
An unstable conductivity display can be caused by an air lock in the installation area of the conductivity probe. Check for air bubbles or insufficient filling of pipes, and follow the recommendations to ensure proper installation.
What to do if pre-metering doesn't function on Ecolab LMI 02?
If pre-metering does not function, it could be due to several reasons. First, check if the release signal “VD start” is available to the system. Next, verify that the metering enable signal is not active for pre-metering. Also, ensure that the product storage container is not empty and check the time setting if a delay time for pre-metering has been set.
What causes 'DETERGENT OVERDOSAGE' in Ecolab LMI 02 Measuring Instruments?
Detergent overdosage can occur if the alarm delay time (detergent overdose delay) is set too short, leading to a local concentration overrun. Change the alarm delay time to resolve this. If the issue persists, the relay for activation of “detergent metering” output may be defective, requiring the instrument to be returned for repair.
What does SYSTEM FAULT 9 mean on Ecolab LMI 02 Measuring Instruments?
SYSTEM FAULT 9 indicates that communication between the electronic boards has been interrupted. Ensure that the connector is correctly connected. If the alarm message persists, return the instrument for repair.
How to troubleshoot no display on Ecolab LMI 02 Measuring Instruments?
To troubleshoot a missing display, check if there is supply voltage and that the fine wire fuse is OK. If necessary, change the fuse.
What does 'SYSTEMS FAULT MEMORY' mean on Ecolab LMI 02?
If the Ecolab Measuring Instruments displays 'SYSTEMS FAULT MEMORY', it indicates that the data in memory is incorrect and the instrument should be returned for repair.
