Assembly and Connection

The LU6 locking unit can be mounted in any mounting orientation.
Failure of safety function!
The LU6 locking unit comes pre-lubricated.
O Do not use a compressed air lubricator.
O Never re-lubricate the LU6 locking unit.
Canted insertion of the piston rod or round bar may damage the scrapers and
seals.
O Make sure that the piston rod or round bar is free of burrs and chamfered.
O Ensure that the piston rod or round bar is never inserted canted.
Destruction of LU6 locking unit!
Exceeding the permissible torsional moment of the piston rod or round bar when
holding or braking leads to destruction of the holding cartridge.
O Comply with the permissible torsional moment (see section "Technical Data").
Assembling the LU6 locking unit on an ISO cylinder
or round bar
Extended braking distance and failure of safety function!
Excessive or insufficient surface roughness either leads to increased wear
or an extended braking distance and therefore failure of the "safe stop function".
O Only use piston rods or round bars with specified surface roughness.
O Observe the permissible material characteristics in section "Technical Data".
Danger of injury!
Assembly is undertaken pressurized.
O Pay attention to appropriate protective clothing.
O Check the fitting and the tubing for the compressed air connection (9) for the
correct position.
1. Remove the protective cap on the LU6 locking unit compressed air connection (9).
2. Connect the compressed air supply.
3. Pressurize the LU6 locking unit with at least 4 bar. This releases the clamping
jaws.
4. Remove the transport rod (8). Keep the transport rod for subsequent
disassembly.
5. Slide the LU6 locking unit over the cylinder piston rod or the chamfered end
of the round bar.

6. Screw the LU6 to the cylinder cover (3) or system using the mounting kit.
Observe the stated tightening torques in both cases.

7. Exhaust the LU6 locking unit. This causes the clamping jaws to hold the piston
rod in place.
8. Remove the compressed air supply again from connection (9).
9. Place the protective cap back inside the compressed air connection (9) before
transporting the cylinder with the mounted LU6 locking unit.
Install the cylinder with preassembled LU6 locking unit
in a system
1. Stop system operation and protect it against being switched on.
2. Return all suspended loads to a statically secure position or remove them from
the system.
3. If required, exhaust stored compressed air from system parts in the immediate
work area.
4. Make sure the relevant section of the system is not under pressure and protect
it from being switched on.
5. Position the cylinder with pre-mounted LU6 locking unit at the designated
location in the system.
6. Install the cylinder tension-free in the system using the appropriate cylinder
mountings.
Connecting the LU6 locking unit and cylinder pneumatics
Short tubing lines ensure shorter response times of the LU6 locking unit.
1. Remove the protective caps from compressed air connections (1) and (9).
2. Connect the compressed air connections of the LU6 locking unit (9) and
the cylinder (1) to the compressed air. Ensure that the connections and tubing
lines are free of dirt particles and foreign matter.
Installing a proximity sensor (optional)
1. Exhaust the LU6 locking unit.
2. Remove the protective caps from one of the thread connections (5)
of the LU6 locking unit (M12x1).
3. First, screw the sensor into the thread (5) up to the stop.
4. Screw the sensor back by approximately 0.75 to 1 turn and fix the sensor
in this position with the lock nut.

Commissioning and Operation

Before commissioning, the installation has to be carefully inspected by a qualified,
trained professional. The performance characteristics in the section "Technical
Data" must be observed.
Failure of safety function!
The locking unit cannot achieve the holding or braking force in the pressurized
state.
O Exhaust the locking unit when holding and braking (0 bar).
Gradual jamming!
If the operating pressure falls below 4 bar, gradual jamming occurs, which can
lead to an increase in brake wear and failure of the safety functions.
O Ensure that the minimum operating pressure of 4 bar is constantly
maintained.
O Secure the operating pressure with an appropriate pressure sensor.
Danger of injury while working on the system!
Working while the system is running can cause major injuries from moving
machinery!
O Maintain a sufficient safety distance.
O Do not work on the system while it is running.
