Set, Activate And Start The Timer - Komet Twin SR140 ULTRA Manuel Technique

Set, Activate and Start the Timer
Calculate required time until inversion
Usually the preset time at least needs to cover the time frame needed to retract the throw radius R of the gun, including an
eventual pre-irrigation time (delay of retraction). The known values, speed of retraction "v" of the irrigation machine in m/h
(meter/hour) and throw radius "R" of the gun in m (meter) result in the following formula:
Time t (min) =
Example
Speed of the hose retraction = 20 m/h - Throw radius of the gun = 60 m - Delay of retraction = 15 min.
Setting of the time
• Press any button until only the number on the right side
starts blinking. Then set the required time (in minutes)
with the arrow buttons. After setting the time, wait
4 seconds until the display goes black. The defined time
remains stored, until it is manually changed.
Activation of timer
• The last set time remains stored in the timer's memory.
Push any button to bring the timer into stand-by mode.
The symbol "S." is blinking on the left side.
• On the right side, the predefined time is blinking. The
timer is now activated. It remains active, in stand-by
mode, for 36 hours.
Start of Countdown
• The countdown of the timer starts automatically through
the implemented accelerometer. The accelerometer will
be triggered through an abrupt movement of the gun (for
example if water is running through the gun).
• During the countdown the dot symbol "." is blinking and
the remaining time is shown on the right side of the
display. After the time has elapsed the gun automatically
performs the inversion.
ATTENTION! The timer is very sensitive. Jumping down
from the irrigation cart for example, may already trigger
the timer. Before leaving the irrigation cart, make sure
that the timer is activated but has not yet started the
countdown.
Functionality control
In case the functionality of the timer is controlled while it is not installed on the gun, make sure to keep the timer in a
vertical position during the test. A horizontal alignment may already trigger the accelerometer of the timer and start the
countdown.
