‘General Conditions of Sale.’
2. SAFETY
Compressed air in its basic state or in its more sophisticated applied forms can result in accidents if it is not
properly used. We therefore draw your attention to the following paragraphs*: The Health and Safety at Work
Act (1974) makes specific requirements on suppliers and users. To conform with these requirements IMI Norgren
Ltd. has, so far as it is reasonably practicable, designed, constructed and tested its products so as to be safe
when properly used. Many of our customers, being suppliers as well as users, are reminded of the imposed
duties of the above Act and when expediting these duties our technical staff will be pleased to advise. We cannot
accept responsibility for the design of plant which might use our equipment and would recommend the use of
European Norm (EN) standards and BS 4575:Part 3 (1988) , (Note compliance with these standards does not in
itself confer immunity from legal obligation). We also suggest the guidance booklet by the Health and Safety
Executive HS(G)39, “Compressed Air Safety” that offers advice on the safe use of compressed air.

3. OPERATING DESCRIPTION
The DeviceNet VP51 is a programmable electronic proportional control valve.
The pneumatic section is a diaphragm actuated precision glandless spool valve, pilot pressure applied to the
pneumatic section controls the output pressure of the unit.
The pilot pressure is generated and controlled electronically. The feedback signal from the outlet port is
compared to the control signal required and ensures a consistent, stable output pressure.
The electronics system requires a nominal 24V DC supply signal (supplied from DeviceNet). With a 150 psi
standard unit, the user can define their requirements through DeviceNet parameters, and set the application
parameters needed for the unit, i.e. speed, proportional & integral gain, thresholds etc.

• Connect pipe-work using 10mm OD, 8mm ID, plastic pipe, cut cleanly at right angles, with push-fit pipe
connections.
• Fit an exhaust silencer to Port 3 if required (this will only slightly degrade exhaust performance)

• Use grub screws provided to plug cross drilled holes in interface plate
• Mount interface plate to ISO-2 sub base with four M6 screws, with gasket between plate and sub base.
• Place three O-rings in three counterbored holes in plate and mount VP51 with two M4 screws.
Electrical Installation
Connect the unit as follows using DeviceNet approved screened cable and a M12 female connector or with a
ready made M12 DeviceNet cable:
Pin 1: Drain (bare)
Pin 2: V+ (red)
Pin 3: V- (black)
Pin 4: CAN_H (white)
Pin 5: CAN_L (blue)
