simultaneously exhausting the cylinder chamber
in the returning direction.

Dynamic brake test
Pressurise cylinder chamber of the DNCKE in
the advancing direction with P = 10 bar while
simultaneously exhausting the cylinder chamber
in the returning direction.
That corresponds to the following test force
(for testing with KEC è Tab. 7).
– The movement begins (danger of crushing).
– The max. permissible travel speed must not
be exceeded.
Exhaust port (2 è Fig. 1).
– Braking begins.
– The cylinder stops.
Determine path from the exhaust start signal
until the cylinder is at rest.
– This path equals the overtravel.
