Introduction
General The Martin®Air Cannon Controller is a reliable, practical system for firing
Martin®Air Cannons at predetermined intervals. The controller uses
programmable logic to energize the air cannons’ solenoids. It reduces the
chance for human error and is expandable to control multiple air cannons in
several structures where material flow problems exist.
The controller is used to fire cannons in a timed sequence. It is available with
up to 10 outputs.
Each controller has a factory-set on-time of 1 second and an adjustable off-
time of 1 to 65,000 seconds. Manual override selector knobs are mounted on
the outside of the enclosure.
Overview of
controller
operation
The controller can be used to fire air cannons in three ways:
• Manually fire individual cannons using the manual override selector knobs.
• Automatically fire all cannons in a timed sequence.
• Automatically fire all cannons in a timed sequence when activated by an
external switch.
(An example of an external switch is a paddle-type flow switch that
monitors flow of material as shown in Figure 1. When material stops
flowing from the hopper, the flow switch inputs are closed and the controller
is enabled to begin the firing sequence. Whenever material is flowing from
the hopper, the flow switch inputs are opened and the controller is disabled;
the firing sequence is deactivated.)
To manually fire individual cannons, it is not necessary to program the
controller. The selected cannon fires when activated by the selector knobs on
the outside of the controller.
To automatically fire all cannons in a timed sequence, the controller must be
programmed for the desired number of air cannons to sequence (from 1 up to
10 air cannons) and the desired off-time (the length of time between each
cannon firing).
To automatically fire all cannons in a timed sequence when activated by an
external (flow) switch, the controller must be programmed as described
above, and the switch must be connected to the controller as follows:
• When connected to the controller’s ENABLE terminal block, the cannons
will fire in the programmed sequence (e.g., cannons 1 through 10 fire in
sequence) until the switch disables the controller and deactivates the firing
sequence. When the switch enables the controller again (activates firing),
the controller resets the sequence to begin with cannon 1 (e.g., if the switch
disabled the controller after firing cannon 3, the sequence will start by firing
cannon 1 the next time it is activated).

Introduction

Martin Engineering M4097-05/18 3Martin®Air Cannon Controller - multiple circuit
Before Installing Controller
1. Remove controller from shipping box.
2. If anything is missing or damaged, contact Martin Engineering or a
representative. Keep any damaged goods subject to examination.
WARNING
!
Before installing equipment, lock out/tag out energy source to
hopper, conveyor, and/or conveyor accessories.
3. Turn off and lock out/tag out energy source according to ANSI standards
(see “References”).
WARNING
!
If equipment will be installed in an enclosed area, test gas level
or dust content before using a cutting torch or welding. Using
a cutting torch or welding in an area with gas or dust may
cause an explosion.
4. If using a cutting torch or welding, test atmosphere for gas level or dust
content.
Before Installation

Martin Engineering M4097-05/18 4Martin®Air Cannon Controller - multiple circuit
Installing Controller
To install the controller, follow the procedures in this manual corresponding
to the following steps:
1. Mount the controller enclosure on a wall.
2. Wire individual air cannon solenoids to controller or, if air cannons are
wired to a solenoid enclosure, wire solenoid enclosure to controller.
3. If using an external flow switch, wire dry contact to controller.
Mounting
enclosure
WARNING
!
All electrical work must be done to National Electrical Code
(NEC) standards.
1. Determine location for controller.
CAUTION
!
Do not mount controller in area subject to shock, vibration,
temperatures exceeding 130°F (55°C), or explosion. Damage
to controller circuitry could result.
2. Mount onto wall with fasteners.
3. Drill conduit holes in controller enclosure for solenoid and power wires.
Use care not to damage internal components. Drill in most weather-proof
location available on enclosure.
4. Using electrical connectors, route wires from solenoid valves to
controller enclosure.

NOTE
Only wiring required is power wire to controller and
N terminals on controller’s printed terminal strip.
1. Connect wires from air cannon solenoids to terminal strip outputs 1
through 10 and N terminals (see Figure 2). Connect number 1 solenoid to
1 supply and N, number 2 solenoid to 2 supply and N, etc. Continue until
all solenoids are connected.
2. Connect ground wire from each solenoid to controller enclosure. Route
power wire (115 VAC, 60 Hz) into controller enclosure.
3. Connect power safety ground wire to terminal block labeled GND.
4. Connect power wires to terminal blocks labeled 110V and COM. Connect
phase to 110V and neutral to COM.
5. Ensure ENABLE jumper is in place.

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.”

!
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.

After Installing Controller
Manually firing
air cannons
1. To manually fire cannons 1 through 10, turn selector knob on door of
controller enclosure to number of cannon you wish to fire. Turn
HAND-OFF-AUTO knob to HAND (see Figure 4), hold for 1 second, and
release. (Selected cannon will fire and knob will return to OFF
automatically.)
2. When finished with manual firings, return selector knob to O. (This
disconnects the manual mode, and prevents accidental firing if the
HAND-OFF-AUTO switch is turned to HAND.)
