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 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
Phase duration Fixed cycle Variable cycle
Adsorption 5 min 10 min, max
Regeneration, total 5 min 5 min
- of which: expansion time ~ 0,2 min ~ 0,2 min
- of which: dehumidi cation time ~ 4 min ~ 4 min
- of which: pressure build-up ~ 1 min ~ 1 min
Standby -- ~ 5 min, max.
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 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 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
