Cycle operation with probe failure
In the event of a fault, the authorised technical service can discon -
nect the element corresponding to the faulty probe, making it possi -
ble to run the cycle. For this reason neither nor is
switched on because of malfunction (emergency operation). The
icon flashes as an indication of abnormal operation and the
program and cycle selection LEDs work.
LED signals on the electronic board
1) For access to the electronic board and wiring: turn off the power
supply at the main switch of the machine and at the automatic
protection switch on the external power supply socket of the
machine.
The electronic board consists of a series of light indicators that are
very useful when it comes to seeing the operation of the machine or
detecting faults.
The indicators are divided into two groups, input and output indica -
tors:
• Yellow input indicator LEDs : they show the information received
by the electronic board.
• Red output indicator LEDs : they show the element activated by
the microprocessor.
