2 Safety
2.1 Safety instructions
–Only use the product in its original condition without unauthorised modifica-
tions.
–Take into account the ambient conditions at the location of use.
–Observe the identifications on the product.
–Only use the product if it is in perfect technical condition.
–Store the product in a cool, dry environment protected from UV and corrosion.
Keep storage times short.
–Before working on the product, switch off the compressed air supply and lock it
to prevent it from being switched on again.

2.2 Intended use
The product is intended to be used as an external stop for a linear drive and
enables the slide to be placed in an intermediate position within the stroke range.
2.3 Foreseeable misuse
Operating the product without suitable cushioning will destroy it.
–Use suitable cushioning components è www.festo.com/catalogue.
2.4 Training of qualified personnel
Work on the product may only be carried out by qualified personnel who can
evaluate the work and detect dangers. The qualified personnel have skills and
experience in dealing with electropneumatic (open-loop) control technology.
3 Additional information

4Function
The stop lever of the intermediate-position module swivels in and out when
the pneumatic ports are pressurised. In the swivelled-out status, the cushioning
component in the shock absorber retainer advances to the stop lever. The slide of
the linear drive is therefore in an intermediate position. The position of the stop
lever can be queried by the proximity switch in the slots .

screws and the accompanying centring sleeves . Tightening torque è Tab. 1
Tightening torque for mounting the intermediate position module. The inter-
mediate position is fine-tuned during commissioning by screwing the cush-
ioning component in or out.

8 Electrical installation
For sensing the stop lever positions:
1. Use suitable proximity switches with a longitudinal cable outlet
è www.festo.com/catalogue.
2. Place the proximity switches in the slots of the intermediate-position module.
3. Mount the proximity switches in the corresponding end position. A minimum
distance of 10 mm from magnetic parts must be observed.
9 Commissioning
Malfunctions may occur if excessive loads are applied to the stop lever.
• The following must be considered in this context:
• The stop lever must be retracted and advanced at the correct time.
• Briefly switch off pressure to the linear drive to retract the stop lever or
pressurise both sides.
1. Push the slide of the linear drive manually to the end position from which it is
to approach the intermediate position.
2. Pressurise the linear drive so the approached end position is retained.
3. Pressurise pneumatic port 1 on the intermediate-position module.
–If required: the stop lever can be pressurised via the sliding pad . The
sliding pad serves as a manual override.
ÄThe stop lever extends.
4. Start a test run with low switching frequency and low impact speed. Linear
drive operating instructions è www.festo.com/sp.
5. Slowly accelerate the payload on the linear drive. The slide of the linear drive
must not make a hard stop against the intermediate-position module.
6. If necessary: adjust the intermediate position by screwing in or unscrewing
the cushioning component on the shock absorber retainer . Maintain the
screw-on length X and the tightening torque A of the lock nut .
7. Terminate the test run.

Malfunction Possible cause Remedy
Hard impact of drive at the
intermediate position
The cushioning component is
defective
Replace the cushioning compo-
nents
The stop element is overloaded Reduce the impact velocity
