Annunciator Setup - Prelube & Postlube

A Pre/Post lubrication system can be driven from the Brain module by enabling it through the Pre/Post Lube Setup Page. This page can be accessed from the main setup by selecting “Outputs Setup”, then “Pre/Post Lube Setup”.

On the Pre/Postlube setup page, the Prelube and Postlube time can be specified. These are the times that the lube output (digital out 1) will run before starting the engine and after it shuts down. Also on this page is the Pre-Lube Valid timer, which is the amount of time after completing pre-lube that the engine can be started or restarted before having to complete the prelube process again.

Optionally, a prelube valid condition can be added. This condition must be met before prelube will be considered complete. If the prelube time finishes and the condition isn’t met, the lube will continue until the condition is met. This condition can be based on any input and threshold.

Valid Condition Modifier

This option requires Brain v3663 and DCT v1.69.366 (or higher). This option only shows up if the "Advanced" button in the top-right of the screen is selected.

The Valid Condition Modifier is an option to change the "Pre-Lube Valid Condition" based on compressor oil temp. That is, when the compressor oil temperature is above some setting the prelube valid condition will change from its normal threshold in the previous box to some new threshold. This can be used if the prelube condition needs to be dependent on oil temp.

To set a condition modifier select the box and enter the oil temp threshold and the new condition target. To remove, select "disable".
