From time to time it may be necessary to recalibrate (
ReTune
) the UC4+
electronics to your sprayer’s hydraulics. Examples of such times are:
•
when a hydraulic solenoid valve is changed
•
when the hydraulic pump is changed or adjusted
•
when the normal working temperature of the hydraulic oil has
shifted significantly from when the system was previously calibrated
If you are running a pull type sprayer and use different tractors to operate the
sprayer, you should run the
ReTune
procedure each time the tractor is
changed. If you have a flow control for the boom hydraulics, set it prior to
tuning. If you change the flow setting by more than 20 percent, you should
ReTune
.
Follow
Section
6.1.1
to
6.1.3
(level booms, working RPM, etc.) before
beginning the
ReTune
. Navigate to the "
ReTune?
" menu prompt in the
SETUP
menu and confirm with the "
AUTO (YES)
" switch. The procedure
described in the
Automatic System Setup
, starting at
6.1.7
will begin.
NOTE: The booms are to be leveled at a normal working height when
ReTune starts – it is not necessary to set them to 35 inches. The
35 inch height is only required during the Automatic/Manual
System Setup.
