Regeneration
As outlined above, the compressed air is
initially fed through the air dryer and dried.
The moisture is temporarily stored in the air
dryer and the dried compressed air passes
into the system.
Discharge valve N111
The discharge valve N111 is a 3/2 way valve
(three connections and two switching
positions) and is closed without current. The
N111 is used only for discharge purposes
(lowering).
For lowering, the discharge valve is controlled
by the control unit J197 together with valves
N150 and 151.

valve and under Discharge)

The air dryer is regenerated during discharge
(lowering). During discharge, the dried
compressed air (Òwaste airÓ) is fed back into
the air dryer where it re-absorbs the moisture
stored there and discharges it into the
ambient air.
