Illustration 1 g00707282The following items can have an impact on the adjustment of the ORS and these items may also determine when the ORS is adjusted: the load factor, the typical fuel rate and the consumption of oil. A typical example of the various factors are listed in Table 1.

(3) This is the amount of oil that is metered into the fuel. This is also the amount of oil that is depleted from the makeup tank.
(4) This is the amount of oil that is consumed in the crankcase during normal engine operation.

Graph of oil consumption versus fuel consumption
Reviewing the report from the S O S Oil Analysis will indicate if the metering rate needs to be adjusted. The rate may need to be increased if the limits of the infrared analysis and the wear metals are too high.The following various factors that are specific to the site can affect the limits of the oil condition:
Altitude
Engine hours
Maintenance
Air cleaners
Oil type and brand
Operating conditionsAlert Indicators
Several conditions can affect the operation of the ORS.ECM
The machine's ECM controls the cycle and the activation of the oil renewal solenoid. Electrical problems with the ORS can also be detected by the ECM. The ECM will deactivate the ORS if there is an electrical problem with the following components:
Oil level sensor for the makeup tank
Fuel level sensor
Oil renewal solenoidCycle the power after the problem is resolved in order to reactivate the system.Oil Level in the Makeup Oil Tank
An electronic oil level sensor is located in the makeup oil tank. If the oil in the makeup oil tank drops to the level of the sensor, the sensor is activated. A warning is displayed. If this warning occurs, the ORS will automatically turn off. The ORS will automatically turn on after the oil level is raised in the makeup oil tank.Fuel Level
The machine's fuel tank is equipped with a fuel level sensor. This sensor works with the monitoring system in order to notify the operator when a low fuel level occurs. If the machine is operated at a low fuel level with an oil/fuel blend, the fuel system can be damaged. The ORS will automatically turn off when the ten percent level occurs in the fuel tank. Refilling the tank will correct this problem. The ORS will be automatically turned on.Fuel
