Manual Boom Operation - Toro Multi Pro 5700-D Service Manual

Manual Boom Operation

During sprayer operation with the sonic boom switch in
the manual position, the spray booms will remain in posi-
tion unless the operator presses a boom actuator
switch. When the sonic boom switch is in the manual
position, the sonic boom light should be illuminated. The
operator will control the boom position with the boom ac-
tuator switches.
Raise Spray Boom
When a boom actuator switch is pressed to raise a boom
section, the electronic control unit (ECU) energizes the
power switch relay and both H--bridge relays for the re-
quested boom section. The energized relays provide a
current path to the boom actuator causing the actuator
to retract which will raise the boom section. The boom
will continue to rise until the operator releases the boom
actuator switch.

Lower Spray Boom
When a boom actuator switch is pressed to lower a
boom section, the electronic control unit (ECU) ener-
gizes the power switch relay for the requested boom
section. The energized relay provides a current path to
the boom actuator causing the actuator to extend which
will lower the boom section. The boom will continue to
lower until the operator releases the boom actuator
switch.
