• Pot life: When the system completes jobs, the
control box counts down from the set 'Pot life'.
When it counts down to '0', the system activates
the alarm of purging.
• Idle period: When the system completes jobs, the
control box counts down from the set 'Idle Period'.
When the time counts down to '0', purge fails.
• Purge shot size: set the total volume of purge.
Note: 'Idle period' restores to the set value after purge.
If purge fails, the operator need to replace the mixing
tube (if the materials are solidified), reset the alarm, and
perform manual purge.
The automatic purge flow is as follows:
