The following information is a condensed version
of the Raven installation and service manual. It is
designed to provide sufficient basic information to
enable the new unit to be calibrated before spraying
is commenced. For more detailed information about
console features, consult the Raven installation and
operational manual.
It is imperative that the Raven console is correctly
programmed, as the system will only work as
accurately as the programmed information entered.
The Raven 4000 series consoles are very similar
however there may be slight differences during
calibration for specific information please refer
to the Raven operator's manual supplied with the
machine.
NOTE: While proceeding through the initial console
programming write down all relevant calibration
values for future reference.
The following steps are very important because the
system will appear to function properly but be very
inaccurate if values are incorrectly entered.

1. Turn the console 'ON' by momentarily depressing
the [POWER] key.

be displayed
NOTE: If this is not displayed or if an incorrect entry
is made during programming turn the console power
switch 'OFF' depress and hold the [CE] key while
turning the power switch back "ON". This procedure
resets the console.
