The control unit is cooled by one or two built-in fans. The fan with a filter, mounted on top of
the electronic section, should produce a slight over-pressure inside the cabinet. It should be
made sure that the external and the built-in fans are not working against each other. The
cleanliness of the filter of the external fan, or if necessary, a replacement thereof is a basic
condition for the faultless operation of the control system. It is forbidden to open the door of
the cabinet of electronic section (or to disassemble the unit) for aeration or any other purpose
while the control system is under power. It is also forbidden and involves the loss of the
warranty to remove, repair or subsequently adjust the PC boards of the control system. The
only exceptions are the replacements of the 1.6 and 6.3 fuses on the front panel of the PC
board of the power supply, and setting the brightness control of the screen. Replacement of
fuses can only be done if the tool machine is in power-off status.
