7.12. Drying Controller (Volume Drystat))

The drying controller is in the solvent drain line from the air duct to the water separator. It consists of
a valve and a sight-glass with built-in level sensor, positioned above the valve.
The drying controller determines the amount of recovery to be expected in a predefined period of
time.
If this particular amount of recovery is no longer attained during the predefined time period, the
garments are dry.
The valve closes after the end of the specified drying time. The recovery causes the volume
(measurement chamber) between the valve and sensor to fill.
When the filling level has been reached, the sensor opens the valve and the solvent drains into the
water separator. This procedure keeps repeating until the filling time (adjustable in the specification
code) is exceeded.
The programme enters the post-drying phase, when additionally a certain temperature is
The measurement chamber must empty within a specific time. If this time is exceeded, an error
message is displayed and the machine switches to the malfunction state.
