Initiate Connection
The 7040 can be operated by
applying a 5 to 24 VDC pulse to
terminal pins 1 and 2, or providing
contact closure across pins 5 and
7. Alternatively, a foot pedal may
be ordered (#2015A) and plugged
into the connector located on the
rear panel.
➃
Air Input Connection
1. Connect the controller to plant air
by first installing the five micron
filter regulator (#2000F755) to
the plant air supply.
2. Install the air tee with barb fit-
ting (#1116 supplied with EFD
tank reservoirs) in the output of
the filter regulator, and install the
black hose with coupling to the
barb fitting. The quick-connect
on the air tee is used to provide
air pressure to the air pressure
regulator on EFD tank reser-
voirs. This connection will be
made during valve installation.
3. Remove the cap plug from the air
input of the controller and attach
the input air hose coupling onto
the controller air-input fitting.
4. Set the pressure at the filter
regulator to 70 psi (4.8 bar).
