Gun Flush Box Controller 570262 Operation (continued)
NOTE: The following instructions are not for use with the PrecisionMix II system. See your PrecisionMix II system
manual 308916 for operation instructions.
Pot Life Monitor and Alarm
NOTE: Pot life timer at each gun is reset when the
system controller senses an air flow signal (typically an
air flow switch) for 40 seconds.
1. Insert the gun into the Gun Flush Box and close
the door when the gun is not in use.
2. If the gun has mixed material in it, the Gun Flush
Box controller will start the pot life timer. When the
set time ends, the Gun Flush Box will automatically
purge the mixed material.
3. If the gun is inactive but not in the Gun Flush Box,
the box controller will activate the alarm light so the
light is flashing.
4. Place the gun in the Gun Flush Box and close the
door. The Gun Flush Box controller will open the
gun and activate the purge sequence.
5. When the light stops flashing, purging is complete.
Reload the material by moving the Operator Switch
momentarily to PURGE (for less than 2 seconds)
then back to MIX.
NOTE: If you want a warning signal before the pot life
time ends, a warning signal of 1 to 10 minutes can be
programmed into the gun flush box controller. See the
Programming Flow Chart on page 16.
The warning output signals can be wired to optional
horns or lights to signal that the potlife timer value is
less than the specified warning time and a gun with
mixed material is out of the box. Within the specified
warning time, the operator can either:
D
Reset the pot life timer by triggering the gun for
a total of 40 seconds or
D
Put the gun back in the Gun Flush Box and
wait for the automatic purge.
Operation
Multiple Gun Operation
Follow the same single gun operating instructions on
pages 19 to 21, taking note of the following additional
information:
D Guns will be loaded and purged in sequential order
(gun 1, gun 2, gun 3, etc.). The sequence depends
on which guns are in their box at the start of a fill
cycle.
D During the automatic purge cycle, only guns with
mixed material loaded will be purged.
D Manual purge will only purge guns which are in their
box. Manual purge will not start until all guns with
mixed material are in their box.
D Automatic purge will not start until all guns with
loaded material are in their box. Operators should
put the guns in their box with the door closed when-
ever they finish spraying.
D If a gun or guns are being taken out of the line for
service (by valve shutoff or other means), one of
the following things must occur to prevent the gun
flush box controller from trying to fill these guns
during the mix/fill mode.
D
Leave the gun in the box, but leave the door
partially open or
D
Take the gun out of the box completely.
NOTE: Purge the gun(s) before taking them out of the
line for service.
