Control Panel - ProSeal 25 Service Manual

Control Panel

The Control Panel (see figure 6) is located on the front right of the machine and has three LED
indicators. A diagram of the Control Panel is shown in figure 7.
1. The top LED when lit indicates the machine is
plugged in and the power is on.
2. The middle LED indicates if the heat is on. Heat
is required for ProSeal Pouch Boards and
ProSeal Flexible Pouches. If lit, the laminator is
in Hot Operation Mode and will heat up to its
factory setting. If not lit, the laminator is in Cold
Operation Mode.
3. The bottom LED is the Temperature Ready
Indicator. If flashing slowly this indicates the
laminator is heating up and has not yet reached
process temperature. A steady light indicates
the unit has reached process temperature and
is ready for use. A rapid blinking light indicates
that the machine is too hot. This occurs when changing from Hot Mode to Cold Mode. In this case,
a steady light indicates the machine has cooled sufficiently for cold processes.
Below the LED lights are two Push Buttons.
1. The top button controls the heating of the roller; it switches the heater on or off. Pushing this
button toggles the machine from Hot to Cold or Cold to Hot Operation. The bottom LED light when
constantly on, will indicate the appropriate temperature as been reached.
2. The lower button reverses the direction of the motor. The motor will continue to run in reverse until
the button is released. This is used to clear jams or foreign objects, should one be drawn into the
laminator.
