5.1.2 Additional controls
Figure 8: Front controls
Emergency stop buttons (1) :
There are 4 emergency stops on the machine. Two are
located on the front of the machine (see section 4.2), and two
are in the same locations on the back of the machine. The
emergency switches are push button switches. When pressed
the rotation of the rolls is stopped immediately, the rolls move
to the open position, the heaters turn off, and the button is
locked into this stop position.
Twist the emergency stop button to unlock it. This allows you
to use the EOI to reset the heaters and start the rolls. Toggle
the roll position switch to lower the rolls again.
Front control panel (2)
,
There are two controls on the front control panel. The first is a
toggle switch (3) that is used to raise and lower the rolls. This
switch will always raise the rolls, but it will only lower the rolls
if the emergency stop is not depressed and the photo eyes in front and behind the roll are
not blocked. The foot switch can be used to override the photo eyes and lower the rolls.
You may want to turn the speed potentiometer to zero at this point as the rolls will start
turning when the foot switch is depressed.
WARNING:
KEEP CLEAR OF THE NIP WHEN USING THE FOOT SWITCH TO
OVERRIDE THE PHOTO EYES.
The second control on the front control panel is the main roll air pressure adjustment knob
(4). Turn this knob to the right to increase the pressure and to the left to decrease the nip
pressure. The pressure is displayed on the EOI as a percent of the total recommended
pressure.
Figure 9: Foot switch
Foot switch
Press and hold the switch to start the rotation of the rolls.
Insert the forefoot completely to use this switch. When the
switch is released, the rotation of the rolls will stop.
