S
Setting the speed and the end position
cushioning:
Tighten the screws of the upstream one-
S
way flow control valves (A) and the end
position cushioning (B) on the DNCKE-...:
– at first completely
– then loosen approximately one turn.
Pressurize:
S
– the complete system slowly.
To do this use safety start-up valve type HEL-... .
– the cylinders at first simultaneously on both compressed air connections 1
(only with DNCKE-...).
This will prevent movement against an unpressurized cylinder chamber.
– the clamping unit at compressed air connection 2 with at least 3.8 bar.
The piston rod then moves slowly into the extended end position.
Start a test run at low frequency and at low impact speed.
S
Repeat the test run increasing the speed step-by-step until the operating
S
speed is reached.
If set correctly, the work load should reach the end position without striking
hard against it.
During the test run check whether these settings on the clamping unit need to
S
be modified:
– The speed of the work load
– The end position cushioning
– The clamping force (if the system is designed for this, by pressurizing the
cylinder briefly with maximum pressure (10 bar); the clamping rod must not
break through.
Remedy if the clamping rod breaks through:
Adjust the clamping unit again in accordance with the chapter "Commis-
sioning – preparation").
Conclude the test run.
