TRIO PLUS HD CONTROLLER
TRIO PLUS HD CONTROLLER - V.4
The Trio Plus HD controller called the V.4. This controller is easily identified by all of the high
amp terminals being the lug style terminals.
The V.4 controller was another evolutionary design from the V.2 and V.3 controls with marked
improvement.
Improvements
Boost Mode- The V.4 controller has new software that allows the machine to safely climb
ramps better than the V.2 or V.3 controller. This is done with a “Boost Mode” that allows
a high amp output for a given amount of time and then not allowing the controller to climb
again for a predetermined amount of time to assure that the drive motor does not over heat
and become damaged.
Lug Terminals - All of the high amp outputs are lug style terminals. These terminals provide
more dependable higher quality connection for the wiring. These connections also make in
field wiring repairs easier on these machines.
Extended Code List - An even more extensive code list was created for the V.4 controllers
breaking the diagnostic codes down into more specific faults.
Backwards Compatibility - The V.4 controller is backward compatible for replacement on all
of our machines with central command II.
THE V.4 controller has all luged high amp output terminals.
