The Low Alarm Offset is the differential
between the operator entered drying tem-
perature setpoint and the upper value of
the Low Temperature Alarm Band. The
function of the Low Alarm "Offset" is to
prevent nuisance alarms and allow the
alarm band to change when the drying
temperature setpoint is changed. The
Offset is factory set to a default value of
10°F.
The Supervisor Password is required to
change the value from the default value to
a user-preferred value.
The Low Temperature Alarm Band is the
band of temperatures in which the Low
Temperature Alarm Setpoint can be set.
The width of the alarm band is factory set
at 40°F. The alarm band is programmed to
track any changes in the Dryer's drying
temperature setpoint. The alarm band will
move up and down with the Dryer's drying
temperature setpoint, staying 10°F [Offset]
below the drying set-point.
The Low Alarm Delay is a time delay to
minimize nuisance alarms. If the drying
temperature at the sensor selected for the
low temperature alarm falls below the
alarm limits the delay timer is activated. If
the drying temperature at that particular
sensor location comes back to within the
alarm limits before the delay timer times
out the delay timer is re-set. However, if
the drying temperature at that sensor
remains below the alarm limits until the
delay timer times out the alarm is initiated.
The Supervisor Password is required to
change this value.
