Spray Gun Control Card Removal/Installation
Replacing a Spray Gun Control Card
WARNING: Do not remove spray gun control cards from the card cage
while they are powered. Either shut off console power or shut off the booth
exhaust fan so that the interlock will remove power from the spray gun
control cards. Failure to observe this warning could result in damage to the
cards.
CAUTION: Do not turn off console power without first performing a program
shutdown. Doing so could corrupt the Engage program and operating
system on the program card.
CAUTION: The spray gun control cards are electrostatic sensitive
devices (ESD). To prevent damage to the cards when handling them, wear
a grounding wrist strap connected to the Engage enclosure or other ground.
Handle the cards only by their top and bottom edges.
See Figure 5-9. Spray gun control cards (2) are installed in the card cage
from left to right. Each card controls two spray guns: the bottom receptacle
is the odd spray gun number; the top receptacle is the even spray gun
number.
To remove a card, disconnect the spray gun harness connectors (3 and 4),
pull down the locking tab (5), then pull the card out of the card cage.
To install a new card, slide the card into the slots in the card cage and seat
the card’s finger board firmly into the connector slot on the backplane (6).
Push the locking tab up to lock the card into the card cage. Connect the
spray gun harness to the two receptacles on the card.
Adding Spray Guns
If the console has an odd number of spray guns, it is possible to add
another spray gun without adding another spray gun control card. If the
console has an even number of spray guns less than 16, add more spray
guns by installing a new spray gun control card in an unused slot. Refer to
System Upgrades in the Installation section for more information on adding
spray guns to an existing system.
For either scenario, open the Guns and Consoles configuration screen,
increase the number of spray guns, and reboot the system before the new
spray guns will be recognized.
NOTE: Cards are installed in the card cage from left to right. Spray guns
are numbered from left to right and bottom to top.
