A
NOTICE
New desiccant has a moisture holding capacity higher than the dryer’s
design regeneration capacity. The desiccant ages in a three- to six-
month time period at which point it stabilizes to an "aged" state. During
this aging process at initial start-up or after desiccant replacement, the
Energy Management System feature should be deactivated.

SETPOINT ADJUSTMENT
On dryers equipped with the optional Energy Management
System the setpoint can be adjusted to match the dryers
operation to the desired pressure dew point.
The following illustrates the method of adjusting the setpoint

The following illustrates the method of adjusting the setpoint for the
heater temperature:
9.5 ENERGY MANAGEMENT SYSTEM (OPTIONAL)
The Energy Management System option includes a dew point sensor
that transmits the outlet pressure dew point to the Microprocessor
Controller. The Microprocessor Controller displays the outlet pressure
dew point in real-time. This option package also includes Energy
Management System, an energy savings feature that matches moisture
loading and regeneration energy usage. The Energy Management
System feature utilizes the data communicated from the dew point
sensor and extends the normal timed switching sequence in proportion
to the moisture loading on the dryer.
When the Energy Management System feature is turned off, all
switching sequences occur as described in Section 7.7. When the
Energy Management System feature is activated, the drying sequence
is governed by the outlet pressure dew point as measured by the dew
point sensor. When the sampled outlet dew point registers below the
customer set point (-43°F default for -40°F dryers), an immediate
change in dryer operation will not be noticeable. The dryer will continue
its normal regeneration process through tower re-pressurization. Once
the tower is re-pressurized, both towers will be at line pressure but air
will only flow through the tower indicated by the status panel. Tower
switch over sequence is delayed until the dew point elevates above the
Energy Management System setpoint, at which point tower switch over
will occur.
To enter a negative number, depress the +/- button.
Otherwise, proceed to the next step.
