DGPI(L)−...−AI F
Fitting the pneumatic components
Fitting in a vertical or sloping position
Warning
If there is a pressure failure, the work mass will slide down. Uncontrolled mov
ing masses can cause injury to people or damage to property (danger of fingers
being squashed); (moving mass = slide mass + mass of the work load).
S Read the documentation for your control system (e. g. SPC11/200).
There you will find pneumatic circuits with which the moving mass can be
prevented from sliding down abruptly.
Select the compressed air ports.
S
In addition to the ports provided at the
factory (A), there are also the alternative
ports (B, C). These are fitted with plug
screws.
Variant ...−D2 (with bilateral air ports):
In this case the air supply cannot be implemented on one side only.
With stroke lengths > 500 mm:
If the DGPI(L)−... is controlled by the SPC11 or SPC200, the compressed air
must be provided on both sides (variant D2).
Only bilateral air supply will guarantee optimum dynamics.
Controlling the DGPI(L)−...:
Use proportional directional control valve
S
type MPYE−... for controlling the speed
and the positioning.
Fig. 15 shows a circuit example.
Please note
This circuit is not suitable for stopping the
slide in the event of a pressure failure.
