Emerson AVENTICS CO1 Notice D'instruction page 15

Limits
• Comply with the limits (explosion protection, material protection). Limits: see
section g 13. Technical data.
Accessibility
Install the product in the system part so that the following connections and oper-
ating parts are always accessible or have enough room:
• Electrical connections
• Pneumatic connections
• Cable and tubing
CAUTION! The permissible bending radii must not be exceeded.
Personnel qualifications
Assembly only by qualified personnel (see section g 2.5. Personnel qualifications
).
Tool
• When assembling in explosive atmospheres: Use low-spark tools (explosion
protection).
Set-up regulations in the country of use
• Observe the set-up regulations in the country of use.
6.1.2 Notes on safety
To eliminate risks during assembly, observe the notes on safety: see section
g 2.6.1. Notes on safety.
6.1.3 Installation conditions
The installation conditions include the specifications that apply specifically to the
product family that your product belongs to.
General requirements
• Make sure that the product is installed in a manner that protects it from all
types of mechanical loads.
• Install the product in an area protected from UV radiation.
Specifications for explosion protection zones (explosion protection)
• Generate and prepare compressed air outside the explosive area.
• If you install additional equipment:
– Ensure that no new ignition hazards result from the installation of addi-
tional equipment.
– Take all additional equipment in the system into account when equalizing
potentials.
• Make sure that the electrical plug connector is installed in a manner that pro-
tects it from all types of mechanical loads.
Any other manner of installation does not conform to ATEX Directive
2014/34/EU.
Specifications for dust explosion areas (explosion protection)
• Compressed air and exhaust are evacuated from the dust explosion protec-
tion area through tubing lines.
This is the only way to ensure that no dust accumulates in the system's atmos-
phere. An increased dust concentration can cause explosions.
• Ensure that Ensure that the minimum ignition energy of the dust in the sys-
tem atmosphere is under the following value: 1 mJ
• Recommendation: Protect the product from dust deposits through a pro-
tected installation. The protected installation is essential if there are large
amounts of dust in your system's atmosphere.
Product-specific requirements
Mounting orientation
• Mounting orientation: see section g 13. Technical data.
• Ensure that there is enough air circulation around the product: Provide
enough distance to adjacent parts (explosion protection).
• If the product is installed near heat sources: shield the product (explosion pro-
tection).
6.1.4 Required accessories, materials and tools
Mounting material
• Wire end ferrules
AVENTICS™ CO1 | R499050034-BAL-001-AI | English
If you use AVENTICS mounting material, see the online catalog for the relevant
data. Important information for assembly:
• Dimensions
• Tightening torques: Observe the values in the online catalog.
If no information is given on tightening torques or you use your own mounting
material, the generally recognized rules of technology apply to assembly.
Tool
• Screwdriver
• Hex key (SW2)
Accessory parts
Depending on the chosen configuration and the application, additional compo-
nents are required to integrate the product into the system and the system's con-
trol.
• Accessory parts for use in explosive areas must comply with the applicable re-
quirements stipulated in the European directives and national laws (explosion
protection).
6.2 Preparation
6.2.1 Notes
• Do not carry out any work on the system during preparation (accident preven-
tion).
• Make sure that the seals are integrated in the plug and not damaged (explo-
sion protection).
• Make sure that all plugs are mounted (explosion protection).
6.2.2 Unpacking and checking the product
1. Unpacking the product.
2. Check the material number to see if the product matches your order.
The material number can be found on the housing of the product.
3. Check the product for transport and storage damage.
Do not install a damaged product. Return damaged products together with
the delivery documents (address: see back cover).
4. Prepare required accessories, materials and tools.
6.2.3 Implementing safety measures
Procedure
All work has to be prepared as follows:
1. Close off dangerous areas (accident prevention).
2. Make sure the system or system part is not under pressure or voltage (acci-
dent prevention).
3. Protect the system against being restarted (accident prevention).
4. Allow the product and adjacent system parts to cool down (accident preven-
tion).
5. Wear protective clothing (accident prevention).
Danger of explosion due to overcurrent!
Overcurrent, e.g. resulting from a short circuit, can cause an explosion in ex-
plosive areas.
Provide for overcurrent protection as per EN 60204-1 if the current in any
u
circuit can exceed either the rated value for a component or the current
carrying capacity of the conductor. The lower value is decisive.
6.3 Installation
Work steps at a glance
Installation consists of the following work steps:
• Step 1: Mount the solenoid coil on the basic valve
See section g 6.3.1. Mount the solenoid coil on the basic valve.
• Step 2: Connect the solenoid coil
See section g 6.3.2. Connect the solenoid coil.
6.3.1 Mount the solenoid coil on the basic valve
1. Remove the mounting nut from the armature system of the base valve.
