84 Change the Sensor Assignment (Thermocouple)
7.8.9 Change the Sensor Assignment (Thermocouple)
The Thermocouple Assignment lets the operator assign a thermocouple from a different
zone to control the heater of the selected zone. This is important in a condition when there
could be mis-wired thermocouples or heaters in the mold.
For example, heater number 1 may be connected to thermocouple 5 and heater number 5
may be connected to thermocouple number 1. In this example, the operator can manually
switch the thermocouple inputs. Change the number in the Thermocouple Assignment field
to the applicable number.
NOTE: The Altanium automatically does a check for mis-wired molds during Mold
Diagnostics. This usually makes adjustments not necessary.
To change the sensor assignment for a zone, do the steps that follow:
1. Touch the zone to be changed.
2. Touch the Advanced Settings drop-down tab.
3. Touch the Thermocouple Assignment field and enter a value.
4. Touch the Accept button.
You also have the option to select No Sensor or Match Zone. When No Sensor is selected, the
system does not use the feedback from the thermocouple to control the zone. Select Match
Zone to easily match a zone with a sensor of the same number. It is typical to use the same
sensor number assignment with a zone. For example, Zone 1 uses Sensor 1, Zone 2 uses
Sensor 2, and the same match for other zones and sensors in the system.
7.8.10 Change the Priority Control Mode
If there is a malfunction during the heat/injection operation, the software will try to bypass
the problem. If this is not possible, the system will start a shutdown sequence. You can select
how the shutdown occurs.
In the case of an Abort condition, if the Priority Control Mode (PCM) is set to Zone mode, the
controller stops the power output to the defective zone and continues to operate all other
zones as usual. If the PCM is set to System mode, the controller will shutdown all power
output to the mold (if the failure occurs on this zone). The PCM is zone selectable, so one zone
may only change itself to OFF, while a different zone could shutdown the mold. The PCM is
set by how critical the zone is to the mold. Usually, the cavities are set to Zone mode, and the
manifolds are set to System mode. The default is System mode for all zones.
The PCM can also be set to Stage mode. In an Abort condition when Stage mode has been
selected, the zones do a shutdown with a slow decrease of the temperature and power in 1
to 4 stages. The shutdown stages are configured on the Staging screen.
To change the PCM for a zone, do the steps that follow:
1. Touch the zone to be changed.
2. Touch the Advanced Settings drop-down tab.
3. Touch the PCM - Priority Control Mode field.
4. Select Zone, System, or Stage in the PCM - Priority Control Mode dialog window.
NOTE: To select Stage mode, the Staged Shutdown must be enabled on the Staging screen.
