The leg set function remains active until both leg pressure readings reach parameter “Final Set Pressure” or until the limiting time is reached. If either pressure reading is switched Off in the Sensor Status menu section, this step will be limited only by the time parameter.
Parameters “Final Set Pressure” “Final Set Time”
The limiting time is set by parameter “Final Set Time”. If the Final Set Time expires before the Final Set Pressure is reached, an error is posted (err: "ASQ ERROR set press not reached"). The set function(s) are deactivated at the end of this step. Normally, this is the last step running in the Autosequence and it triggers no other steps. *If this state was triggered by an Umbrella Lock, then an error is posted (err: "ASQ ERROR pause – umbrella lock") and the end of this step triggers the Umbrella Lock Pause step.
Conveyor Push Refill This step activates the conveyor push function for a short time period set by parameter “ram refill time”. If the time is set to 0, the feature is effectively switched off. This feature closes the clevis pin gap at the conveyor to keep the pan from moving backwards when nearby shields advance or when the shearer passes.
Parameter “ram refill time”
The end of this step triggers no other steps.
Umbrella Lock Pause This state posts an error (err “ASQ ERROR paused - umbrella lock”). This state exits when the Umbrella Lock is removed or when the limiting time expires. The limiting time is 90 seconds. If this step ends due to the limiting time, the ASQ stops and an error is posted (err: "ASQ ERROR abort - umbrella lock"). If this step ends because the Umbrella Lock is removed, it triggers the First Prewarning step.
Errors ASQ ERROR paused – umbrella lock Umbrella Lock caused ASQ to pause; will resume if umbrella removed soon enough. ASQ ERROR abort – umbrella lock ASQ aborted because Umbrella Lock remained more than 90s. ASQ ERROR aborted ASQ aborted by Quickstop, Lockout, Stop key, etc. © Caterpillar
