Air Cannon Controller - multiple circuit
Figure 3. Air Cannon Inputs
NOTE
PLC uses an octal numeral system.
6. Determine number of air cannons to be controlled.
7. Move “+124” wire (A) to terminal number (1—10) that corresponds with
number of air cannons to be controlled. For example, to use ten air
cannons connect “+124” wire to 10 as labeled.
8. If using an external flow switch, follow the procedure under “Wiring
external flow switch to controller.” If not, follow the procedures under
“After installing controller.”

flow switch to
controller
WARNING
!
Before making any connections, lock out/tag out electrical
supply to controller according to ANSI standards (see
“References”).
NOTE
See Figure 2. ENABLE always resets the controller to cannon 1
while material flows. See “Overview of controller operation”
under “Introduction” for more information.
2. To use ENABLE, do the following:
a. Remove factory-installed jumpers between ENABLE terminal blocks.
b. Connect external flow switch dry contact to ENABLE terminals.
c. Connect external flow switch ground to controller.
