Material Ready Alarm -
If the Material Ready alarm is enabled, 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.
1st:
ON:
Material Ready Alarm sounds after the first and only
the first batch of material is ready to drop from the
Vacuum Chamber.
Material Ready Alarm sounds after every batch of
material is ready to drop from the Vacuum Chamber.
This mode can be useful in lab environments.
OFF:
Disables the Material Ready Alarm
Material Temperature Alarm -
When the Material Temp alarm is
enabled, 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 VBD.
ON:
When the Material Temperature Alarm is enabled,
the alarm will sound when this alarm is triggered.
OFF:
Disables the Material Temperature Alarm
Residence Alarm (labeled “Residence”) -
When the Residence Alarm
is enabled, an alarm will sound if dried material has sat in the
retention hopper too long. The RAL parameter determines when a
residence alarm will occur based on elapsed time and weight of
remaining material in the retention hopper. See the RAL parameter
for more information.
ON:
When the Residence Alarm is enabled, the alarm
will sound when this alarm is triggered.
OFF:
Disables the Residence Alarm
Throughput Alarm -
If the Throughput alarm is enabled, the alarm
will sound if the material in the Retention Hopper is used faster than
the dryer can produce dried material. (Material level reaches RTL
