This is an example of an Alarm Setup
Loop Break screen. When actual tempera-
ture is outside the deviation band, if the
temperature is not moving toward the set-
point at a rate greater than or equal to X°F
over Y seconds, then the dryer will alarm
on Loop Break. Once the actual tempera-
ture is within the deviation band, the Loop
Break is ignored.
This is an example of an Alarm Setup
deviation screen. If the actual temperature
goes outside this temperature band (High
or Low) for a set amount of time, the dryer
will give a deviation alarm. With the prop-
er password (see page 4-32, screen 85),
these values can be changed.
This set value is the minimum difference
between the regeneration inlet and outlet
temperature for the wheel rotation alarm.
Once this difference is reached for the time
value, the dryer will alarm wheel rotation
failure.
This is a delay time for the wheel rotation
alarm from start-up so regeneration can
come up to temperature.
This screen shows the return air tempera-
tures at which the dryer will give a passive
alarm, and when the dryer will shutdown
on High Return Air Temp.
