9.3 Soft Start Routine
During the soft start routine, all the zones warm up simultaneously, and at the same rate. The
soft start routine results in even thermal expansion and identical residence time on the
material.
NOTE: Soft start is not active during staged startup.
The soft start sequence is:
1. If necessary, the bake out starts.
NOTE: If the ART process has not been completed, the ART Process screen will appear
when starting soft start.
2. The ART process begins if it has not already run.
3. Soft Start displays in the status bar. The power applied to the heaters varies from the
probes to the manifold zones, the probes receiving less power and the manifolds
receiving more. All of the zones increase in temperature at the same rate to ensure a
smooth even thermal transfer within the mold. This helps to eliminate mold leakage.
4. Once all temperatures are near their setpoint, running is displayed in the system mode.
5. You enable Soft Start on the System Setup screen, refer to Chapter 10.
9.3.1 Adjusting the Soft Start Minimum Limit
The soft start limit is used to calculate the window between the lowest temperature zone and
the highest temperature zone in the system. This window is maintained throughout the soft
start process and determines the gap between the coldest and hottest zones. Generally,
lowering the soft start limit value decreases this gap, contributing to greater thermal
uniformity of the hot runner system from a cold startup.
To set the soft start minimum limit, refer to the System Setup screen, Chapter 10.
9.4 Alarm Screen
The Alarm screen displays errors that occur. When an alarm is active, an icon in the Alarms
button in the system footer turns yellow and flashes red. Touch the Alarm button to open
the Alarm screen.
NOTE: For a description of the alarm conditions displayed on the Event History screen and
Alarm screen, refer to Section 9.6. For a description of the abort conditions displayed
on the Event History screen and Alarm screen, refer to Section 9.7.
