If the dryer has the dewpoint monitor
option installed, this screen will show the
actual dewpoint of the process delivery air.
With the dewpoint monitor option
installed, there will only be an actual dis-
play (no setpoint value). Although the
dryer is capable of producing dewpoints
much lower than -40
°F {-40°C}, the mini-
mum sensor range is -40
°F {-40°C}.
Dewpoint control will automatically adjust
the regeneration temperature to maintain
dewpoint setpoint. Dewpoint control is not
active with -40
°F {-40°C} setpoint.
This is the password entry screen that
gives the user access to the Set Up, Test
Mode, and Alarm History screens. The
user can get to the password protected con-
trol functions through this screen by press-
ing the Scroll button and the adjust set-
point button (-) at the same time. This
works only if you are on menu #1 (Screen
5). The access codes are as follows:
Set Up Screens 754
Test Mode Screens 755
Alarm History Screens 756
To exit the password section, enter 500 and
press scroll or cycle the power.
