Settings
The settings screen allows you to toggle between Dewpoint Demand and straight Time
cycle. While in Time cycle, the dryer will shift towers every four hours. When utilizing the
optional DPDS, the dryer will complete its four hour regeneration and go into a standby
mode until the outlet dewpoint has reached the dewpoint monitor’s set point. When
dewpoint demand is not purchased, this screen will not be available.
3.2.4
Alarms
The alarm screen will display any and all alarms. Alarms are displayed in the order in
which they occur, for instance the top alarm is always the most recent one. When an
alarm situation occurs, this screen will automatically be displayed. When an alarm
clears, the operator interface will automatically return to the MAIN screen. The optional
fail-to-shift alarm comes with an alarm horn. The F4 key will allow an operator to disable
this horn while they are in the area to fix the alarm condition. When fail-to-shift is not
purchased, this function will not be present. Using the other function keys, per the
above designations, you may toggle to any other screen.
When screen is switched with a pre-existing alarm, this alarm screen will not
automatically pop back up until all alarms are cleared.
