EN/IEC 60079-17 Explosive atmospheres - Part 17: Electrical installations inspection and maintenance
The PVE-EX is in conformity with listed EU Directive (s) and EU harmonized standards:
EMC Directive 2004/108/EC
EN/IEC 61000-6-2:2005 Electromagnetic compatibility (EMC) - Part 6-2: Generic standards - Immunity for industrial environments
EN 61000-6-4:2007/A1:2011, IEC 61000-6-4:2006 Electromagnetic compatibility (EMC) - Part 6-4: Generic standards - Emission standard for industrial environments

Enviromental conditions

Altitude up to 2000 m
Maximum relative humidity 95% non condensing
Rated pollution degree (evaluated for pollution degree 2 rating)

Protection

All PVE-EX actuators comply with protection class IP67 and IP69k according to EN60529. However, in particularly exposed applications, protection in the form of shielding is recommended.

Specific conditions for safe use ("X"-mark)

Repairs of the flameproof joints must be made in compliance with the structural specifications provided by the manufacturer. Repairs must not be made on basis of values specified in tables 1 and 2 of EN/IEC 60079-1.
Originally supplied "SD cable glands" may not provide sufficient clamping. User shall provide additional clamping of the cable to ensure that pulling and twisting is not transmitted to the terminations.
Fasteners used for enclosure must be made from stainless steel grade A4 or stronger (Yield stress 210 MPa)

Warnings

Before implementing actuators in any application, read all warnings. Warnings are listed next to the most relevant section and repeated in the chapter PVE-EX warnings on page 18.
Do not regard the warnings as a full list of potential risks. Depending on the application and use, other potential risks can occur.
Warning
All brands and all types of directional control or proportional valves, which are used in many different operation conditions and applications, can fail and cause serious damage.
You must perform a risk assessment. The machine builder/system integrator alone is responsible for making the final selection of the products and assuring that all performance, safety and warning requirements of the application are met.
The process for choosing the control system and safety levels is governed by the Machinery Directive 2006/42/EC and EU harmonized standard EN 13849 (Safety related requirements for control systems).

Warning
The flameproof enclosure is provided with metric threaded entry M20x1,5 6H according to ISO 965-1 and 3 complying with Article 500.8 of NEC ANSI/NFPA 70.
To maintain the flame proof abilities installer must use the wiring method complying with the requirements contained in Article 501 NEC ANSI/NFPA 70.

Mounting of Cable

The PVE-EX is equipped with a top part that holds the cable gland for cable installation.
1. Remove the insulation of an appropriate length to expose the wires.
If wire shall be connected to the earth terminal, make sure to have insulation enough to crimp into the cable shoe and attach properly to the chassis.
Cable material must be according to the specification.
2. Strip the wires so that a suitable length of cooper is exposed.
3. Insert wires and cable through the gland and grommet.
4. Insert wires into screw terminals and tighten the screws.
5. Pull the cable back to the position where the cable insulation is still going through the grommet.
6. Immerse the terminal compartment and mate the male and female connector.
7. Ensure that the O-ring is properly seated in its groove and that excess wires are not trapped between
the two elements.
8. Tighten the screws (M6 x 12 mm) to the specified torque 6 ± 1 N•m.
9. Tighten the gland to the specified torque in which the cable is locked correctly.

Cable Gland

Use screws made from stainless steel grade A4 or stronger (enclosed).
The PVE-EX is required to be installed with a cable specified to the surrounding conditions and to the given diameter of the cable gland.

PVE-EX Pre-certified Cable Gland

Appropriate certified entry devices with flame barrier shall be used. For cable diameter specification, refer to the relevant instruction from the supplier of the pre-certified
cable gland. In order to comply with the product certification the pre-certified cable gland must be marked with the following markings:
Marking NEC
Group II AEx db IIB Gb (-40° C ≤ ta ≤ +80° C) [-40° F to +176° F]
Warning
Pre-certified cable gland must have thread: M20 x 1.5 mm and must be sealed with O-ring Ø20 x 1.5 mm at the threaded entry.

Maintenance, service and troubleshooting

PVE-EX Installation, Start-up and Operation

The inspection intervals and definitions are to be seen in the standard IEC 60079-17 and the corresponding Inspection schedules-table. Operators must under no circumstance try to repair or open a PVE-EX. A failing or damaged PVE-EX is to be replaced.
Warning
The installation must be performed as intended in order to have a safe system and a proper functional application. In a case of damage to enclosure, plug or cable, the PVE-EX actuator must be replaced. Please refer to the information in this manual for assistance, or consult with a professional.
Warning
All national safety regulations must be fulfilled in connection with installation, start-up and operation of Danfoss PVE-EX electrical actuation's. Furthermore, the requirements of the Declaration of Conformity and national regulations for installations in potentially explosive atmospheres applies as well. Disregarding such regulations involves a risk of serious personal injury or extensive material damage.
Warning
Work in connection with the electrical actuations must be performed only by professionals and qualified persons.

Safety Guidelines

If failure, damage or defect occurs, the PVE-EX has to be replaced.
A failing PVE-EX must under no circumstance be repaired.
No modifications, which could damage the explosion-safety and protection, are allowed to the PVE­EX, the cable gland, or on the cable.
Demounting a PVE-EX must be done in an atmosphere with no potential for explosions.
The manufacturer has the application responsibility and is solely responsible for the safety of the system.
Deviations from recommended torque when mounting parts can harm performance and the PVE-EX.
Do not adjust, bend or damage the position transducer (LVDT) as this will influence the safety and performance.
If replacing the PVE-EX, the electrical and the hydraulic systems must be turned off and the oil pressure released.
Hydraulic oil can cause both environmental damage and personal injuries.
Actuator replacement can introduce contamination and errors to the system. It is important to keep the work area clean and components should be handled with care.

Warnings

PVE-EX warnings

Warning
All brands and all types of directional control or proportional valves, which are used in many different operation conditions and applications, can fail and cause serious damage.
You must perform a risk assessment. The machine builder/system integrator alone is responsible for making the final selection of the products and assuring that all performance, safety and warning requirements of the application are met.
The process for choosing the control system and safety levels is governed by the Machinery Directive 2006/42/EC and EU harmonized standard EN 13849 (Safety related requirements for control systems).
Warning
The installation must be performed as intended in order to have a safe system and a proper functional application. In a case of damage to enclosure, plug or cable, the PVE-EX actuator must be replaced. Please refer to the information in this manual for assistance, or consult with a professional.
Warning
Not applying to the Operational Conditions can compromise safety.
A PVG with PVE-EX can only perform according to specification if conditions in this Installation Guide are met.
In particularly exposed applications, protection in the form of a shield is recommended.
If the PVE-EX is in fault mode the quality of performance and validity of feedback is limited depending on the fault type.
Error signals from more PVE-EX’s must not be connected together. Inactive error pins are connected to ground and will disable any active signal. Error pins are signal pins and can only supply very limited power consumption.
After replacement of actuators or cables wiring quality must be verified by a performance test.
By actuation outside specified supply voltage range PVG will have reduced performance.
The PVE-EX is not designed for use with supply voltage outside nominal.
Obstacles for the Pilot oil can have direct influence on spool control.
Reduced pilot oil pressure will limit spool control.
Pilot oil pressure outside specification can damage the PVE-EX.
The PVE-EX must be installed so that the flanged joints are not within 30 mm of a solid object that is not part of the PVG.
