7.5.13 Changing the Abort Window
Specify how many degrees above or below the setpoint to initiate the abort and shut down.
The default setting is 11 °C (20 °F).
Abort Example: Setpoint = 300°F, Abort = 20°F.
The abort will be initiated above 320 °F or below 280 °F and shut the zone or the system down
based on the PCM directive. If the setpoint is changed to 350 °F, the abort will be initiated
above 370 °F or below 330 °F. The setting always represents an amount above and below the
current setpoint.
To change the abort setting for a zone:
1. Touch the zone to be changed.
2. Touch the Abort Window and enter a new value.
3. Touch the Accept button.
7.5.14 Changing the Output Mode Setting
In hot runner temperature control systems, there are two different methods for switching
power output to the heaters; Zero Cross Control or Phase Angle Control. Each method has its
own set of advantages, but generally they offer very similar results.
Altanium provides the flexibility to run each zone in either mode. The default setting is Zero
Cross for all zones.
To change the output setting for a zone, do the following:
1. On the Quick Set screen, touch the zone to be changed.
2. Touch the Output Mode field to toggle between the Zero Cross and Phase Angle
modes.
7.5.15 Zone Slave
Some of the most vulnerable components in the mold are the thermocouples. If a
thermocouple fails, Altanium will initiate an alarm and display an error on the Alarm screen
for the affected zone. At this point there are three choices:
1. Stop molding, remove the mold and repair the fault. This may not be desirable or even
possible.
2. Switch the zone to Manual control mode and continue processing. This has limitations
as Manual mode is not able to compensate for changes in the process that affect the
heater's power requirements, i.e. shear heat.
3. Slave the faulty zone to another. Due to the symmetry in the design of hot runner molds,
frequently there are other zones that have very similar thermal characteristics as the
faulty zone. Altanium can apply the power output from a fully functioning zone to the
zone with the defective thermocouple. This means that any processing changes that
affect the power requirements of the heaters are automatically applied to the defective
zone. It is similar to repairing the defective thermocouple without ever opening the
mold.
