Lift/Lower Actuators
Three electric linear actuators are used on eTriFlex machines to lift and lower the
cutting units. Each lift/lower actuator is unique and cannot be interchanged with
each other. The lift/lower actuators may be referred to by number: #1 = center
(rear), #2 = left, #3 = right. The front lift/lower actuators retract to lift the cutting
units, while the center (rear) lift/lower actuator extends to lift the cutting unit.
Each lift/lower actuator has its own on-board controller. To operate, the lift/lower
actuators require 48V logic power (supplied by the logic relay), a connection to
the 48V power bus (supplied by the main contactor when energized), and a
connection to the CAN bus to send and receive control messages.
The lift/lower actuators are not serviceable, and are best tested by using the
information provided on the InfoCenter display as described in the following test
procedure. Refer to
Appendix A (page A–1)
for circuit wiring information.
Note:
If a lift/lower actuator (SC2, SC3, or SC4) is replaced for any reason, the
machine software must be updated; contact an Authorized Toro Distributor for
assistance. If the lift/lower actuator is removed for any reason, the lift/lower
actuator must be calibrated; refer to
Calibrating the Lift/Lower Actuators (page
5–83)
