Section 42 - Automatic Lubrication System 04/10 OM4207 42-14 Symptom Possible Causes Corrective Action Pump Pressure Builds Very Slowly Or Not At All No signal at solenoid. Check timer. Controller Does Not Operate No electric power to controller. Turn on electric power to pump. “POWER” LED should light, “PUMP ON” LED should light when “MANUAL LUBE” is pressed. “PUMP ON” LED is lit, But Load Connected To Termi- nals 3 & 4 Will Not Energize Printed circuit board failure. Remove and replace. Load Connected To Termi- nals 3 & 4 Energized, But “PUMP ON” LED Does Not Light Printed circuit board failure or key- pad failure. Remove and replace.
Bearing Points Excessively Lubricated Controller memory mode is off. Switch controller memory mode to ON. Injector output adjustment setting too high. Readjust to lower setting. Bearing Points Are Not Sufficiently Lubricated Timer/controller cycle time setting too low. Set to longer cycle time or reevaluate lube requirements. Injector output adjustment setting too low. Readjust injector output setting. Timer/controller cycle time setting does not deliver lubricant often enough. Set to shorter cycle time or reevaluate lube requirements. System too large for pump output. Calculate system requirements per plan- ning manual.
