Indication of Sensors for Boom Folding
In case of failure to fold the boom, with a fully functional hydraulic
system, sensors located on the boom may cause an interruption of the
boom folding.
˜
ATTENTION! The folding sensors are mounted only on booms
with a width of 120’ (36 meters).
If the boom is in negative tilt position, this can lead to damages on the
boom when folding! These sensors are therefore installed to protect the
boom.
If a sensor is defective or missing, folding of the boom is automatically
interrupted, until the sensor is replaced.
A junction box (see picture) at the rear of the sprayer has electric
connections to the folding sensors, and a button with an LED light is
mounted on the front side of the junction box.
The LED light blinks correspondingly to how the system detects the
sensors - see the table below.
How to Make an Emergency Folding of the Boom
If you need to transport the sprayer for changing a defective folding sensor, first ensure that nothing else prevents the boom
from being folded correctly and that no persons are in the folding area!
Now press the button with the LED light once on the junction box - this will override the sensor alarms.
Continue folding the boom into transport position by using the controls in the tractor.
This emergency mode for the sensors is reset only after the tractor has been turned off and restarted.
Boom width Blinking mode for LED light State of sensors
Up to 100’ (30 meters) Blinks for 1 second, pauses for 1 second, and repeats. No sensors are installed or detected. Normal
operation for boom folding.
120’ (36 meters) Blinks four times a second, pauses for 1 second, and repeats. Four sensors detected. Normal operation for
boom folding.
120’ (36 meters) Blinks shortly once a second, pauses for 1-2 seconds, and repeats. Left folding sensor defective or missing.
120’ (36 meters) Blinks shortly twice a second, pauses for 1-2 seconds, and repeats. Left tilt sensor defective or missing.
120’ (36 meters) Blinks shortly three times a second, pauses for 1-2 seconds, and repeats. Right tilt sensor defective or missing.
120’ (36 meters) Blinks shortly four times a second, pauses for 1-2 seconds, and repeats. Right folding sensor defective or missing.
120’ (36 meters) Blinks continuously 5 times a second. Emergency mode. Protection disabled.
