Operation
Dispense Material
A shot can be initiated using either the gun trigger or the
"Initiate Shot" button. See "Tap" and "Hold" Gun
Modes on page 20.
Maintenance Mode
When using Maintenance mode for anything other
than shutting down the machine, close the material
valves on the coupling block to avoid accidentally dis-
pensing material. See AR Pour Gun manual 312888
for more information.
To perform cleaning, maintenance, or other work on the
AR Pour Gun without error codes being generated, use

and hold the bottom soft key for two seconds from the
idle run screen.
When in Maintenance mode, the gun dispense valve
can be opened and closed by pressing the top soft key
twice or by press the gun trigger. Once the top soft key
has been used to open or close the gun dispense valve,
the gun trigger will be disabled. To regain the ability to
open and close the gun using the trigger after using the
top soft key, exit and re-enter Maintenance mode.
