SENSORS
Two optical sensors are fitted to the machine to detect the corrugated board entering and
leaving the machine.
The sensor consists of a 24Vdc amplifier unit with digital display, mounted at the top
left corner of the machine, and a fibre-optic cable that is mounted such that the end of
the cable ‘sees’ the corrugated board and emits a red light that is clearly visible to the
human eye.
TO SET UP SENSOR.
Switch on the machine. The red and green numbers will show and a red light will be seen shining
from the end of the fibre.
Press the mode button and hold for three seconds – the number display will be replaced with the
word EASY or FuLL.
Press the manual button – to show FuLL (full access mode).
Press the mode button then press the manual button until display reads rESo (high resolution).
Press the mode button SEVEN (7) times – display will scroll through:
‘toFF ----’,
‘diFF oFF’,
‘Eco oFF’,
‘rE’,
‘Hold’
‘L on rESo’
until red and green numbers show again as above.
It is very important that the display should show the modes listed above. If any of the modes
are incorrect, press the up or down arrow to change.
When all modes are correct and the red and green numbers are displayed, the preset value can be
adjusted as follows:
Press manual button until GREEN number (preset value) reaches the required setting, close the dust
cover, the sensor is now set and will switch when current value reaches the preset value.
Nominal settings are 50 to 70 but should be approximately 50 higher than the red figure when there
is no board in the machine.
Example: If red number is 0, set green number to 50. If red is, say, 17, set green to 70.
