Product identification
Comply with the product information on the product and the packaging.
5 Assembly
O
Let the product acclimatize for several hours before commissioning; otherwise, water may
condense in the housing.
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.
O
Make sure that the relevant system part is not under voltage or pressure before you
assemble the product.
O
Protect the system against being switched on.
Assembling the pressure switch and connecting the pneumatics
1. Make sure that the system is not under voltage or pressure.
2. Connect the pressure switch with the pressure system:

Electrically connecting pressure switch form A
O
Only use connection cables which fulfill the required cable quality (EN 600079-14)
and the cable fitting diameter from 4.5 to 11 mm.
O
Use a suitable temperature-resistant cable with ambient temperatures of > 70 °C.
1. Disassemble the electrical connector.
Fit the connection with the screw terminals (M
The terminals are intended for cross-sections of up to 1.5 mm
2. Connect the protective conductor.
3. Connect the electrical connector.
4. Check that the cable fitting is assembled to the plug to ensure the IP65 protection class
(M = 1.8 Nm + 0.2 Nm).

5. Carefully fit the electrical connector to the pressure switch to ensure the IP65 protection
class (M = 0.4 Nm + 0.1 Nm).

Only operate the pressure switch in an electrical circuit with safe isolation from the
mains (PELV in acc. with DIN VDE 0100-410, IEC 364-4-43, HD 384.4.41 S2, EN
60079-14). The electrical circuit must be potential-free (not grounded).

Commissioning and Operation

Risk of injury due to uncontrolled actuator movements when the pneumatics are switched on!
There is a danger of personnel injury if the system is in an undefined state.
O
Put the system in a defined state before switching it on.
System is operating under pressure.
Incorrect installation could damage the maintenance unit/device and cause serious injury.
O
Before start-up, check that all connections, ports, and maintenance devices have been
correctly installed.
Commissioning the pressure switch
Proceed as follows to commission the pressure switch:
1. Check that the pressure switch is correctly assembled (see assembly and safety
instructions) and make sure that all of the pressure switch connections are correct.
2. Secure the components to be switched to prevent unintentional responses, and apply
voltage.
3. Apply the compressed air to the system.Achtung
4. Check that the switch outputs are functioning properly.
6
Setting the switching point
1. Increase the switching point pressure by turning the adjustment screw (1) to the right (+).
The adjustment screw is self-holding and also remains in the set position without any
additional securing, even under unfavorable circumstances.
2. Reduce the switching point pressure by turning the adjustment screw (1) to the left (–).
Factory setting: pressure switch = 3 bar; vacuum switch = 400 mbar
3. Use an external pressure gauge to check the setting value (switching point).
The switching point is continuously adjustable, even during operation.
The optimum selection range is when the switching point is in the middle of the
switching pressure range.
A pressure gauge can be used as an aid.

Service and Repairs

Cleaning and servicing
W
Never use solvents or strong detergents. Only clean the product using a slightly damp cloth.
Only use water and, if necessary, a mild detergent.
W
Do not use high-pressure cleaners for cleaning.
Maintenance
The pressure switch is maintenance-free. Please contact the service department at AVENTICS if
you have any technical problems.

Disassembly and Exchange

Danger of injury if disassembled under pressure or voltage!
Disassembling when under pressure or electrical voltage can lead to injuries and damage to
the product or system components.
O
Make sure that the relevant system part is not under voltage or pressure before you
assemble the product.
O
Protect the system against being switched on.
