Connecting the compressed air
RTC-BV, RTC-SB and CKP
On the RTC-BV, RTC-SB and CKP cylinders either both
pressure connections at one side or one pressure
connection per side can be connected.
O Observe the connection direction of the compressed
air.
Connection direction of compressed with the RTC-BV
RTC-CG/HD
On the RTC-CG/HD cylinder either both pressure
connections at one side or one pressure connection per
side can be connected.
O Observe the connection direction of the compressed
air.

All cylinders
1. Remove any protective plugs or protective labels from
the connections.
2. Make sure that the compressed air supply is shut off,
then connect the compressed air lines. An arrow at
each connection indicates the direction of the cylinder
movement.
3. Make sure that all unused connections are properly
plugged.
4. To prevent uncontrolled cylinder movements on
starting, increase the pressure slowly until the cylinder
is in the right position.
The cylinders of the RTC-CG and RTC-HD series are
equipped with an auxiliary channel (1) for air duct,
that has no drive function.

Setting the speed and cushioning
Risk of injury or damage!
A cylinder that is operated without speed control can
reach high speeds, and may cause injury or machine
breakdown.
O Make sure that the cylinder is always operated with
speed control.
The cushioning, that is the impact of the piston at the end
covers of the cylinder, is set with the cylinder cushioning
screw (1).

Cushioning screw of the cylinder
When the cushioning is being set, the cylinder must be
loaded as in normal operation and the speed must be
increased gradually to the desired operating speed.
Normally the speed is controlled by throttling the exhaust
air from the cylinder chambers with a check-choke valve.
Set the piston speed and cushioning as follows:
1. Make sure that the compressed air supply is zero to
both chambers and then slowly increase the
compressed air supply to the desired operating
pressure.
2. Fully tighten the cushioning screws (1) in both end
covers, then unscrew them by half a turn.
3. Open the check-choke valve.
