Auto Lubrication function component connections | |
The Machine Control ECM will use the Auto Lube Relay in order to control the Auto Lube Pump Motor.
One side of the Auto Lube Relay is coil is connected to an ECM sinking output driver. The other side of the relay coil connected to system voltage that is supplied through the 5.0 amp Sensors Fuse.
When the ECM determines that the Auto Lube cycle should begin, the ECM will turn ON the sinking driver for the relay. This will allow the system voltage to energize the relay coil. When the relay is energized, system voltage that is supplied through the 10.0 amp Auto Lube Fuse will be directed through the relay contacts in order to energize the Auto Lube Pump Motor.
The ECM will cycle the Auto Lube Pump Motor according to cycling parameters that are configured in the Monitor "Performance" menu.
The following Auto Lube parameters can be configured.
Auto Lube Duration - The cycle time that the Auto Lube function will be ON when the cycle starts. The selectable range is 2 minutes to 8 minutes in 1 minute increments. The default value is 5 minutes.
Auto Lube Interval - The time that the Auto Lube function will be OFF between run cycles. The selectable range is 0.5 hours to 2 hours in 0.5 hour increments. The default value is 1 hour.
Temporary Start ON - Allows the user to override the regular cycle time and manually start one auto lube cycle at a time. The ECM will cycle the Auto Lube system for the configured duration time.
In order to configure the Auto Lube Parameters, select the "Performance" menu from the Monitor Main Menu. Then select "Auto Lube System".
The Machine Control ECM will energize the Auto Lube Relay according to the configured cycle parameters when the following machines conditions are present.
- The Engine is running.
- The Implement Lockout Switch is in the OFF position.
- Either the Main Pump Pressure Switch is closed OR the Swing Pilot Pressure Switch is closed indicating that the machine is "working".
- No machine travel is indicated in Gear 2 as indicated by the Transmission Output Speed Sensor.
When the ECM is counting the Interval time between cycles and one of the conditions that is listed above changes, the ECM will stop the count. When the correct machine conditions are present again, the ECM will continue the Interval count from where it was stopped.
Once an Auto Lube cycle is started, the ECM will continue the cycle for the configured Duration time regardless of the state of the required machine conditions. If the Engine is turned OFF during the Auto Lube cycle, the ECM stop the cycle. The ECM will continue the cycle for the remainder of the cycle time once the Engine is started again.
