This is an example of an Alarm Setup
Loop Break screen. When actual
temperature is outside the deviation band,
if the temperature is not moving toward
the setpoint at a rate greater than or equal
to X°F over Y seconds, then the dryer will
alarm on Loop Break. Once the actual
temperature 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
proper password (see page 4-29, 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 set
time value, the dryer will alarm wheel
rotation failure.
This is a delay time from start-up so
regeneration can come up to temperature.
This screen shows the return air
temperatures at which the dryer will give
a passive alarm, and when the dryer will
shutdown on High Return Air Temp.
