MATERIAL SHUTDOWN
ALARM:25
Material Shutdown
This alarm triggers if the Material Shortage alarm is set to
"SHUTDOWN" and is it determined that the heating hopper has been
fully depleted of material via the VFA parameter criteria. When this
alarm triggers, the ULTRA enters a Shutdown state automatically.
This alarm can be useful. For example: at the end of the day, one can
intentionally run the heating hopper empty (by turning off its feed
loader) and have the ULTRA automatically initiate a shut down at the
appropriate time.
MATERIAL READY
ALARM:26
Material Ready
If the Material Ready alarm is enabled under
the “Alarm Setup" menu,
this alarm will trigger after the first and only first batch of material has
completed a full vacuum cycle. After 15 seconds, the audible portion
of this alarm will automatically silence. The first batch of material will
remain under vacuum indefinitely until this alarm is cleared. There are
two main purposes of this alarm:
1. To alert the operator that dry material is ready for the process.
2. To act as a hold-back, when necessary, giving the operator
additional time to prepare the process.
AUTO SHUTDOWN
ALARM:27
Auto Shutdown
This alarm triggers when an Auto Shutdown, that is, a shutdown at a
pre-determined time, has commenced. "Commencement" is defined
as the time at which the final vacuum chamber fill has occurred.
HH MATERIAL LOW
ALARM:28
Heating Hopper Material
On ULTRA's with an optional Heating Hopper Level sensor, this alarm
triggers when the "HH Mat. Level" alarm is enabled under the "Alarm
Setup" menu and the level in the heating hopper has dropped below
the HHA parameter value.
MATERIAL TEMP
ALARM:29
Material Temp
When the Material Temp alarm is enabled under the "Alarm Setup"
menu, during any instance where the Heating Hopper is called upon to
dispense material into the vacuum chamber and the T2 (heating
hopper exit) temperature is below the ESM parameter level, this alarm
will trigger. Its purpose is to alert the operator that insufficient heating
has occurred, most likely from a process throughput that exceeds the
capacity of the ULTRA.
