DISPLAY SECTION
Left display shows roller nip setting or motor current.
When roller rotation mode is not active:
 the roller nip setting is shown in the left display, rotate hand wheel to move roller up or down.
When roller rotation mode is active:
 the motor current is shown in Amps.
Right display shows roller pre-pressure setting or actual roller pressure.
When the top roller does not touch the bottom roller or material:
 the display shows pre-pressure setting.
When the top roller is touching the bottom roller or material:
 the display shows current line pressure, only when value is higher than set pre-pressure value.
HEATER CONTROL SECTION
This section controls the temperature of the top roller.
Before switching the heater “ON”, move the top roller up until it is free not touching the bottom roller
(to prevent hot spots on the top and bottom roller.
Press heater button “ON” to start warming up of the top roller.
Press increase or decrease set point button to set process operating temperature.
During heating up the “heater ON LED” [30] is on and the “below set point LED” [28] is on.
At the end of the heating up period, the “heater on LED” [30], the “above set point LED” and the “at
set point LED” [27] will flash until the top roller will become steady at the set point temperature.
When the temperature of the top roller is at set point the “heater ON LED” [30] will go off and the “at
set point LED” [27] will be on.
From cold, the laminator takes approximately 30 minutes to reach 120
0
C (250
0
F). The heater will
maintain the selected temperature to within ±5
0
C (9
0
F).across the entire roller face.
It is quite normal that, during and after the process, the “set point LED’s” [25,27,28] and the “heater
on LED” [30] occasionally flash. This indicates that the temperature controller is maintaining the
roller temperature within the set point bandwidth.
