70 Abort Window
7.6.5 Abort Window
The Abort Window lets you set a range of how many degrees greater than or less than the
Temperature Setpoint to cause an abort and shut down of the system. The default Abort
Window setpoint is 11 °C (20 °F).
Abort Example: Temperature Setpoint = 300 °F, Abort Window = 20 °F.
Temperatures greater than 320 °F or less than 280 °F will cause an abort condition and
shutdown the zone or the system as told by the PCM directive. If the Temperature Setpoint
is changed to 350 °F, then temperatures greater than 370 °F or less than 330 °F will cause the
abort condition. The Abort Window setpoint is the same number of degrees greater than and
less than the Temperature Setpoint.
To change the abort setting for a zone, do the steps that follow:
1. Touch the zone to be changed.
2. Touch the Frequently Used drop-down tab.
3. Touch the Abort Window and enter a new value.
4. Touch the Accept button.
7.6.6 Output Mode
In hot runner temperature control systems, there are two different methods used to switch
the power output to the heaters: Zero Cross Control or Phase Angle Control. Each method
has its own set of advantages, but usually they have almost the same results.
The Altanium system lets you run each zone in one or the other mode. The default mode is
Zero Cross for all zones.
To change the Output Mode for a zone, do the steps that follow:
1. On the Quick Set screen, touch the zone to be changed.
2. Touch the Advanced Settings drop-down tab.
3. Touch the Output Mode field to toggle between the Zero Cross and Phase Angle
modes.
7.6.7 Zone Slave
The components that are the most sensitive to damage in the mold are the thermocouples.
A thermocouple failure in a zone causes an alarm and shows an error on the Alarm screen for
that zone. When this occurs, one of three operations can be done:
• Stop the mold operation, remove the mold, and repair the fault. This may not be
necessary or possible to do during an injection operation.
• Change the zone to Manual control mode and continue the injection operation. This has
its limits, because Manual mode cannot compensate for changes in the process that
have an effect on the heater's power requirements (example: shear heat).
• Slave the defective zone to a different zone. Because of the symmetrical operation in the
design of hot runner molds, frequently there are other zones that have almost the same
thermal characteristics as the defective zone. The Altanium can apply the power output
