Percentage Timer
The percentage timer regu-
lates the revolution time of the
system. See Figure 22-1.
The amount of water which the
operator applies is determined
by setting the percentage timer.
A percentage timer setting of
100 percent indicates the end
tower of the system would
move continuously, providing
the shortest revolution time.
One hundred percent is also the setting at which the
minimum amount of water can be applied.
If the percentage timer is set at 50 percent, the revo-
lution time of the system and the water application
amount is doubled. The end tower of the system
would move for approximately 30 seconds out of
each minute at a setting of 50%.
NOTE
• The percentage timer determines the per-
centage of one minute which the end tower
of the system will run, therefore, regulating
the revolution time of the system.
• Refer to the system’s sprinkler chart to pro-
vide water application amounts at different
settings.
• The Percent Timer Setting Calculations sec-
tion explains the calculation process for
determining water applications at different
percent timer settings.
Hour Meter
Records the number of hours
the system has operated, includ-
ing both hours with and without
water (or wet and dry time). See
Figure 22-2.
Volt Meter
The volt meter displays
the voltage being de-
livered to the machine
from the control panel.
See Figure 22-3.
The recommended
operating voltage is the
nominal supply voltage.
See Figure 22-4.
During normal operation
the meter should read
approximately the nomi-
nal supply voltage. See
Figure 22-4.
NOTE
• Some long or high amperage machines may
need to be run at a higher voltage but never
at a voltage above the maximum allowed volt-
age.
!
CAUTION
• DO NOT OPERATE THE MACHINE IF THE
VOLT METER READS BELOW THE MINIMUM
ALLOWED VOLTAGE OR ABOVE THE MAXI-
MUM ALLOWED VOLTAGE. SEE FIGURE 22-4.
• OPERATING THE MACHINE OUTSIDE THESE
LIMITS COULD CAUSE DAMAGE TO THE
DRIVE MOTORS AND OTHER ELECTRICAL
COMPONENTS. SEE FIGURE 22-4.
• CORRECT THE LOW VOLTAGE PROBLEM
BEFORE RESUMING OPERATION.
