Setting times of the operating phases

In its standard version the dryer is delivered with a time-dependent control system. The 

phase sequence occurs in a fi xed cycle.

With the optional dewpoint-sensing control, the dryer can also be operated at variable cycles 

(depending on the dewpoint).

The following table provides information on the duration of the individual phases

Overview of operating and control elements

ON/OFF switch

The ON/OFF switch (2) is located to the side of the switchbox and above the mains plug (1, 

see fi gure):

◊ 

If it is set to 0, the power supply is disconnected and the dryer is switched off. The main 

valves are (V1, V2) are open, while the expansion valves (V3, V4) are closed. This means that 

the air can circulate in the main processing direction, even if the dryer is switched off.

◊ 

If the switch is set to 

I

, the dryer is switched 

on and begins to operate in fi xed cycle mode 

(i.e. time-controlled).

◊ 

If the switch is set to position 

II

, the dryer is 

switched on and begins to operate 

— with compressor synchronisation

— in variable cycle mode (i.e. dew-point-cont-

rolled).

Position

 II

 is only relevant for operation with 

the optional  compressor synchronisation and/

or dewpoint-sensing control
