This is the upper end of the Low
Temperature Alarm Band.
The Supervisor Password is required to
change the calculated value to a
user-preferred value. This screen only
displays the value. The Low Alarm offset
and the Low Alarm Band should be modi-
fied in order to change this value.
This is the Low end of the Low
Temperature Alarm Band.
The Supervisor Password is required to
change the calculated value to a user-pre-
ferred value.
This is the Temperature Not Met Alarm
Time Delay, which occurs on every start-
up. The temperature of the selected RTD
must reach the setpoint within the time
delay or the temperature not met alarm
will be activated. The time delay is factory
set for four hours, which is the typical dry-
ing time recommended for most moisture
sensitive hygroscopic polymers. This time
delay provides ample time for the material
within the drying hopper to come up to the
selected drying temperature. This helps to
avoid nuisance alarms while the material
in the hopper heats up.
The Supervisor Password is required to
change the default value to a user-pre-
ferred value.
