The solenoid coils are controlled via the M12 plug. A yellow LED on the valve indicates the current-carrying solenoids. The switch position assignment can be recognized via the numbers 12 and 14.
You can find out more information about the valve options at “Technical Data” and in the online catalog (www.aventics.com/pneumatics- catalog).

Manual override
Each valve has a manual override, “turn and detent” (yellow knob) or “turn” (red knob) depending on the version. In both cases it is activated by a turning motion. Do NOT press! The switch position assignment can be recognized via the numbers 12 and 14.

Assembly

Check that the minimum or maximum values stated in the technical specifications are not exceeded.

CAUTION

Danger of injury if assembled under pressure or voltage!
Assembling when under pressure or electrical voltage can lead to injuries and damage to the product or system components.

• Make sure that the relevant system part is not under voltage or pressure before you assemble the product.
• Protect the system against being restarted.

Uncontrolled movements of incorrectly connected compressed air lines.
Incorrectly assembled compressed air lines with plug connections could come loose when pressure is applied to the single valve, resulting in injuries or damage to the device.

• Always check that the plug connections are effective.

NOTICE Risk of damage to the single valve

2. Fasten the valve (2) by means of two self-tapping Pozidrive screws (6). Tightening torque 1.1 … 1.3 Nm screwdriver PZD no. 1.
3. Make sure that the manual override is in position 0. Carefully turn it into the zero position, if required.
4. Mount the valve cover (3). Make sure the seal (7) is correctly positioned. Tighten the three hexagon screws (8) with 1.0 … 1.2 Nm.

Connecting the pneumatics on the CL03 single valve

NOTICE Risk of valve damage due to congested exhaust!
Closed exhaust outlets will lead to air congestion and valve damage. The connection “VENT” in the base plate must also not be closed.

• Make sure that connection R is open and preferably provided with a silencer.
• Connect the “VENT” connection to a tube that exhausts the air outside the zone. Alternatively, if the valve is mounted in a protected area, for example in a cabinet, you can also fit a silencer to “VENT”.
• Ensure adequate ventilation through the exhaust air connection and connection R.

The single valve is connected to the compressed air system via connections in the base plate. Pilot air is supplied externally via connection X, which is always present on the base plate. The pilot control valves are always exhausted via channel R.

• Fit exhaust air connections that are not connected to an exhaust air line with a silencer.
• Provide unused connections with blanking plugs.

Pneumatic connections on the base plate

1. External pilot control connection
2. Pilot control exhaust air connection
3. Ventilation connection

Connecting the single valve CL03 electrics

CAUTION Dangerous voltage
A power pack without safe isolation may lead to dangerous voltages in the event of a malfunction. Injuries from electric shock and system damage may be the consequences.

• Only use a power pack with safe isolation according to EN 60747, VDE 0551 classification! The corresponding electrical circuits are thus SELV/PELV circuits in accordance with IEC 60364-4-41.

NOTICE High current load
Current loads over 1 A per connector pin will damage the system.
Do not exceed the permissible current load of 1 A per connector pin.
The CL03 single valve is supplied and controlled via the A-coded M12 round plug 1(,4 ).

Assignment of the M12 plug, A-coded, on the single valve CL03

Proceed as follows:

1. Ensure that enough free space is left for the electrical connections so that the permissible minimum bending radii are adhered to.
2. Insert the cable onto the round plug connector.

There are two controls (connector pins) permanently assigned to valve solenoids 12 and 14 for the valve position.

1. Only solenoid 14 must be connected for single solenoid valves. The second control for solenoid 12 remains unused.
2. The following assignments are made in the 3/2 directional valves:
   • Solenoid 14 and pneumatic connection 4
   • Solenoid 12 and pneumatic connection 2

Commissioning and Operation
