3-4 Motor Control

The speed of the rollers is continuously adjustable between 0 and 1.5 m/min. (0 and 4.9 ft/min.) Pressing the ￿ key runs the rollers in forward direction, pressing the ￿ key reverses the direction of the rollers (as long as this button is pressed). The stop key stops the roller movement.

Slow-mode

The machine has a so-called slow-mode, which can be activated by pressing the foot switch. To maintain slow-mode, keep the foot switch pressed.

Once the machine is running in slow-mode, interrupting the Photoelectric Cells does NOT stop the machine; an audible beep will be heard, and the roller speed will be 0.6 m/min (2”/min) only. Releasing the foot switch will stop the machine.

Changing from slow-mode to normal running mode without stopping (to prevent stop marks on the substrate):

During slow mode (keep the foot switch pressed), press the ￿ (forward) button on the control panel. The machine will run at its pre-set speed.

Next, release the foot switch.

Finally, release the ￿ (forward) button.

Changing from normal mode to slow-mode without stopping:

Press the foot switch

NOTE: Releasing the foot switch will stop the machine.

Reversing the machine

To reverse the rotation of the rollers, press the ￿ (reverse) button. As long as this button is pressed, the machine will run in reverse direction, at a speed of 0.6 m/min (2”/min) only. Releasing this button will stop the machine.

Care must be taken not to have loose clothing, long hair, jewelry and fingers pinched between the pull rollers at the rear side of the machine.

The rotation of the rollers will stop when:

The Photoelectric Cells in front of the main rollers are interrupted NOTE: This does NOT happen when the foot switch is used (slow-mode)

An emergency stop button is pressed

The foot switch is pressed for a short moment

Excessive unwind tensions are set (the motor will be shut off electronically, press the stop button on the control panel to reset)

The stop button on the control panel is pressed
