RUN EXCITE: Service & Maintenance Manual - rev. 1.5
3.1.14. ELEVATION MOTOR
This is a linear actuator equipped with 24 Vdc motor, integral reduction gear and a rod that is
pushed backward and forward by the motor. This rod acts upon a frame connected to the front
wheels of the machine: when the rod moves so does the frame, thereby lowering raising the
machine.
The actuator has a built-in Hall effect sensor which acts as an encoder, generating pulses when the
motor moves. This furnishes a feedback signal on the motor movements, which is used for tracking
the position of the rod and hence the elevation of the machine.
3.1.15. AUTOTRANSFORMER
It’s a device which receives the 110 VAC input and generates the 220 VAC output to power up the
machine.
3.1.16. LIMIT SWITCH
This is a NC microswitch which defines the zero-reference position for the elevation mechanism:
the switch is positioned so that it is pressed by the machine during the reset procedure, thereby
defining the reference position.
