Automated lubrication systems

Industrial lubrication control panels use LED indicators to display system status and fault conditions. Understanding these signals helps operators respond quickly, reduce downtime, and maintain optimal lubrication performance.

System Fault Indicator

When a system fault occurs, the red LED light will illuminate to alert operators that an error has been detected.

During this condition:

  • The lubrication system will stop functioning until the error is cleared
  • The GLC 2200 controller will display the specific fault on the digital screen
  • The siren and strobe light will turn off
  • The fault can be cleared by pressing and holding the left arrow button on the controller for 3 seconds

Types of Fault Alarms

Er:LL — Low Lubricant Level

Indicates that lubricant levels are below the required operating threshold.

Er:CY — Backup Time Expired

Occurs when the programmed number of cycle counts is reached before receiving input.
This results in no grease flow to the lubrication points.

Er:SY — System Error

Indicates an internal system fault requiring inspection or servicing.

Why Monitoring LED Indicators Matters

Correct interpretation of control panel indicators helps:

  • Prevent lubrication system failure
  • Reduce costly equipment downtime
  • Improve maintenance response times
  • Extend machinery lifespan

For technical support or lubrication system servicing, contact the DRS SARL technical team.

Signals can be transmitted to SCADA for optimal monitoring. Available signals but not limited are as follows:

  • System Healthy – Electricity to control panel
  • Pump Run – When pump is running
  • Cycle Indication – grease flow recognition
  • Grease Low Level
  • Common Alarm
  • Interlock: Only operates when equipment is operational
