means it cannot determine if the batch is dry. The machine is still able to run if the humidity
sensor is broken, but it cannot run on automatic drying any more. In order to run the ma-

• Clean lint filter
The dryer controller will monitor input 16 to check if the filter needs to be cleaned. If the
controller detects that the filter needs to be cleaned this message will be displayed. This
message is automatically removed when the filter is clean again or when the machine is
stopped.
• Overheating switch
The input for the overheating switches (input 9) is, or has been, in the off state while the
heater was switched on. This means that (one of) the overheating switch(es) is activated.
When the overheating switch isnt active anymore, the message will be reset.
• Delayed start in:
Delayed start has been programmed and the timer for the delayed start is counting down to
0. At the moment the counter reaches 0, the machine will automatically start (see Section 4.3
on page 18)
• Maintenance request
The maintenance request counter is 0 and the machine needs maintenance. The number
of batches which can be done between 2 maintenance requests is adjustable with machine
parameter 5). Resetting the maintenance request can be done via the System Set-up menu
(see Section 4.7.4 on page 34).

the S
