2 Function
2.1 Motor Operation
The heater plate drives are actuated by the user via the foot plate (refer to
Section 010-2.3). The drive motor (Figure 030-1, Item 6) is then energized
with 24VDC. The shaft of the drive motor is connected to the eccentric cam
(Figure 030-1, Item 7) via an E-clip connection (Figure 030-1, Item 5); as the
drive motor turns, the eccentric cam rotates. The rotation of the eccentric cam
moves the guide strips (Figure 030-1, Item 4) and applies pressure to the
spring (Figure 030-1, Item 1), causing the heater plate to close against the
roller. Power to the motor is interrupted as the guide strip actuator contacts
the “plate on roller switch” (Figure 030-1, Item 2), leaving the heater plate
against the roller for ironing.
When the user releases the foot pedal, the drive motor is energized in the
opposite direction. The eccentric cam rotates; pressure is released from the
spring and the heater plate moves away from the roller. The drives continue
until the “plate off roller switch” is actuated by the guide strip.
Note:
The raising and lowering path cannot be adjusted.
