AC motor controller.
The 1230 controller offers smooth precise control of motor speed and
torque. When used with hydraulic systems, the 1230 turns the pump motor
on and off and also controls valves on the hydraulic line—thus controlling the
hydraulic path for Lift and Lower operations.
These controllers are fully programmable through Curtis’s optional 1311
handheld programmer or 1314 PC programming station. The programmer
provides diagnostic and test capability in addition to configuration flexibility.
The 1230 is also designed to work with the optional Curtis 840 Spyglass
data display and the optional Curtis 1312 tiller multiplexer.
