LSM Technologies develops "Warning Label" for ON / Off Road Lubrication Systems

As part of our ongoing "continuous improvement", LSM Technologies has developed a "Warning Sticker / Label" that is provided with each of our On- Road and Off- Road Automatic Centralised Lubrication (ACL) Systems. 


Unlike other ACL Suppliers, LSM Technologies provides a In- Cabin Warning / Manual Push Button as standard for On- Road and as an Option (we have never supplied one without), for Off Road ACL Systems.

The In- Cabin Warning Amber Warning light in the dash provides four (4) primary functions in monitoring the ACL System:

  1. Power Check: When the vehicle ignition occurs, the Amber Light will illuminate for 3 seconds and then extinguish. This function provides for checking that the Warning Light in the Push Button is functional (bulb is not blown), that the fuse is intact and that power is being supplied to the Pump Unit / ACL System- if this does not occur then FAULT.
  2. System Failure: Should the Amber Light illuminate continuously, then this means that the ACL System is not reaching the correct Pressure (On- Road) or that there is a blocked line / failed Progressive Feeder (Off- Road)- if this occurs then FAULT
  3. Resetting Alarms: Sometimes a lubrication system can go into FAULT mode occasionally due to an instance of high back pressure. As such, if the Warning Light illuminates continuously (FAULT), then by pushing the Push Button the Alarm will reset, the Amber Light will extinguish and the system will try and function again. However, should the Warning Light illuminate continuously again, then ACL System definitely has a FAULT that needs immediate attention.
  4. Manual Lubrication: By Pushing the Push Button once, the Automatic Lubrication interval is interrupted and a Manual Lubrication Cycle is added immediately. After completion of the Manual Lubrication Cycle the ACL System will continue back to its Automatic mode. This is a handy feature when a vehicle has entered water or is working in water and the operator wants to add an extra lubrication cycle (in between the Automatic Cycle), to purge the bearings under such conditions. Please note: Pushing the Button continuously will not enter multiple manual cycles- that is, when the Push Button is pressed once it will enter the Manual Lubrication Cycle- another Manual Cycle can not be completed until it has finished the first cycle. 

Now, even with all the "bells and whistles" for monitoring / warning for our ACL Systems, there is a critical requirement and onus of responsibility on the Operator to be observant and the new Warning Sticker provides for instructions to ensure this occurs.

Some special notes:

  • As can be seen from the Warning Sticker the Operator needs to be aware and attentive of the two primary FAULTS and if they occur take immediate action.
  • Ignoring the FAULTS will mean that the machine bearings may not be getting lubricated and this will cause premature wear and damage.
  • FAULT #1: It is critical that the Operator observes that the Warning Light does illuminate for 3 second and extinguishes after Ignition- if not then FAULT. If this fault occurs then there could be no electric power to the Pump Unit- maybe a fuse is blown? If no power is getting to the Pump Unit then of course the ACL System has stopped and no lubricant is being applied to the bearings.
  • FAULT #2: As with other warning lights, it is critical that the Operator observes if th Warning Light Illuminates continuously- otherwise FAULT. If this fault occurs then either the Lubricant Reservoir is empty, Pumping Element is worn or the ACL System has blown a main line hose (no pressure), Progressive Feeder has seized- Bearing Point / Line has blocked (high back pressure), etc. In all these situations, the ACL System has stopped and no lubricant is being applied to the bearings.  

Another special note on Fh and Oh data storage:

  • One of the unique monitoring features of the KFGS Pump Units (Off- Road vehicles) and the IG502E Controller (On- Road Vehicles), is that the CPU stores accumulated Oh (hours that the Pump Unit has actually operated successfully) and Fh (hours that the ACL System has stopped- FAULT#2 mode)- neither can be reset or erased.
  • A combination of the Oh and the Fh should match the Machine Operating Hours and if not, then this means that Power has not been supplied to the Pump Unit for the difference in hours (eg Oh+Fh= Machine hours= 0 Difference).
  • Oh and Fh are only stored whilst power is applied to the Pump Unit and if there is a deviation between the Fh / Oh hours and the actual Machine Operating Hours, then this indicates that FAULT #1 has not been checked and / or has been ignored.
