page 4-32, screen 85).
This screen shows the alarm setpoint for a
Dewpoint alarm. With the proper pass-
word, it can be changed (see page 4-32,
screen 85). The defaults are -3°F {-5°C}
for 180 seconds. If the control senses -3°F
{-5°C} or higher for 180 seconds, the
dryer will alarm.
This is the dewpoint high deviation alarm
value. With the proper password, it can be
changed (see page 4-32, screen 85). When
in dewpoint control, if the actual dewpoint
goes above the setpoint in screen 67 for
the set amount of time, the dryer will
alarm “Dewpoint Deviation High”.
This is the dewpoint low deviation alarm
value. With the proper password, it can be
changed (see page 4-32, screen 85). When
in dewpoint control, if the actual dewpoint
goes below the setpoint by this value for
this amount of time, the dryer will alarm
“Dewpoint Deviation Low”.
