Connecting the Energ ySmart
Control to System Components
(continued)
Connecting the Air Pressure Sensor
The EnergySmart Drying System uses data from the Dwyer 616 Differential
Pressure Transmitter (DPTs) installed on one leg of the optional dust collector
for drying air pressure information.
CAUTION:
Always disconnect and lock out the main power sources before mak-
ing electrical connections. Electrical connections should be made only by quali-
fied personnel.
To connect the DPT to the EnergySmart Dryer electrical panel:
1
Disconnect and/or lock out main power to the EnergySmart Dryer.
2
Route the wires for the air pressure sensor to the EnergySmart Dryer
electrical panel.
3
Open the door of the EnergySmart control panel and
determine the location
of the entry port on the dryer’s control panel for the control system inter-
connecting wires of the air pressure
sensor.
4
Drill or cut the entry port.
4b
If using electrical conduit, cut the entry
port and then run customer supplied
conduit from the EnergySmart Dryer’s
electrical enclosure to the sensor.
5
If using electrical conduit, insert the
wiring for the air pressure sensor through the port in the dryer’s control
panel.
Secure the wires with an appropriately-sized strain relief.
6
Connect the wiring for the air pressure sensor to the dryer’s electrical
panel
as detailed in the supplied wiring diagram.

IMPORTANT:
Always refer
to the wiring diagrams that
came with your sensor and
EnergySmart Dryer before
making electrical connec-
tions.
NOTE:
On systems without a Dust Collector, the air pres-
sure transmitter is inside the dryer.
