2 Safety
2.1 General safety informations
– Observe labelling on the product.
– Prior to mounting, installation and maintenance work: Switch off power supply
and secure it from being switched back on.
– Store the product in a cool, dry, UV-protected and corrosion-protected environ-
ment. Ensure that storage times are kept to a minimum.
– Comply with the handling specifications for electrostatically sensitive devices.
– Observe tightening torques. Unless otherwise specified, the tolerance is
±20%.
2.2 Intended use
Fig. 1
The EFSD electric stopper cylinder is intended for use in stopping the transported
material.
This product can generate high frequency interference, which may make it neces-
sary to implement interference suppression measures in residential areas.
2.3 Training of specialised personnel
Installation, commissioning, maintenance and disassembly should only be con-
ducted by qualified personnel.
The qualified personnel must be familiar with installation of electrical control sys-
tems.

4.1 Function
The electric stopper cylinder isolates/stops transported material in transfer sys-
tems. Cushioning over a stop is done through an air cushion. Retraction of the
stop (release of transported material) and the position inquiry are done electric-
ally.
There are 3 positions:
Fig. 2
– Position 1:
Stopper cylinder closed in initial position (closed):
Stop is extended and located in the initial position. The stopper cylinder is
ready to stop a transported material.
– Position 2:
Stopper cylinder closed in stop position (closed):
The stopper cylinder travels to the stop and moves the stop from the initial pos-
ition into the stop position. This causes the transported material to be braked
and then stopped through internal dampening.
– Position 3:
Stopper cylinder opened (open):
Stop retracts and releases the transported material.

6.1 Electrical installation
WARNING!
Risk of injury due to electric shock.
• For the electric power supply, use only PELV circuits that ensure a reliable elec-
tric disconnection from the mains network.
• Observe IEC60204-1/EN60204-1.

2Electrical connection (sensor)
Fig. 6
1. Switch off power to the controller. It is not sufficient just to cancel the enable
signal.
2. Safeguard the controller from being switched on again unintentionally.
3. Use permitted connecting cables. Frequently, an unscreened cable guide is
sufficient for the 24V signals. Screened control lines must be used in areas
with strong interference.
4. Connect stopper cylinder to the controller at the ports 1 and 2 è Tab. 2.

ÄThe "Power" LED lights up green. Depending on the position of the stop,
the LED "Open" or LED "Closed" lights up yellow.
2. Extend stop by creating a 0-signal at the input of the port1 è Tab. 2.
ÄThe LED "Closed" lights up yellow.
The switching status at output 1 of the port 2 is a 0-signal.
The switching status at output 2 of the port 2 is a 1-signal.
3. Travel with transported material into the stop position.
ÄThe stop is pushed into the stop position.
The LED "Closed" continues to light up yellow.
4. Retract stop by creating a 1-signal at the input of the port1.
ÄThe transported material is released. The LED "Open" lights up yellow.
The switching status at output 1 of the port 2 is a 1-signal.
The switching status at output 2 of the port 2 is a 0-signal.
5. Execute a test run. In doing so, check whether the stop moves through the
intended positioning cycle completely. If necessary, correct the cushioning
setting.
After a successful test run, the stopper cylinder is ready for operation.

• Turn screw for cushioning setting6:
– Clockwise (+) = increase in cushioning force
– Anti-clockwise (–) = decrease in cushioning force
ÄThe stop should reach the end position safely. Observe the maximum
load to be stopped dependent on the transport speed

8 Operation
WARNING!
Risk of injury from touching hot surfaces.
Contact with housing can cause burn injuries. This can frighten people and cause
them to act in an unpredictable manner. This can lead to other forms of secondary
damage.
• Avoid unconscious touching of the housing.
• Inform operating and maintenance staff about the possible hazards.
• Before maintenance work: Let the drive cool down to room temperature.
WARNING!
Risk of injury due to unexpected movement of components.
• Protect the positioning range from unwanted intervention.
• Keep foreign objects out of the positioning range.
9 Cleaning
• Clean the outside of the product with a soft cloth. Do not use aggressive
cleaning agents.
