2. DOWN section / emergency−lowering valve
13
14
The down section is constructed in a similar way to the up section.
S Initial position:
DOWN spool (14) is closed leak−free in the 0 position
S Down travel / acceleration:
DOWN spool (14) is progressively opened by the electro−proportional
valve (DOWN solenoid); this results in smooth acceleration
S Deceleration:
DOWN spool (14) is progressively closed by the electro−proportional
valve (DOWN solenoid); this results in smooth deceleration of the lift
to standstill
S Power failure / evacuation:
With the electrical emergency−lowering valve (optional), the car can
be lowered using DC voltage (⇒ 4.2.4)
S The car can be lowered slowly with the manual emergency−lowering
valve (13)
