Woodward High Output Digital Valve Positioner (DVP）DVP5000/DVP10000/DVP12000

at the time of installation is required to assure satisfactory operation of the product.

Verify details concerning installation mounting requirements: Ground straps, lock washers, etc.

2.5 Mechanical Installation Requirements

This section provides the general information for mounting location selection, installation, and wiring of

the Digital Valve Positioner (DVP).

2.5.1. Unpacking the Shipping Carton

• Before unpacking the control, refer to the inside front cover of this manual and to the Regulatory

Compliance page for warnings and cautions. Be careful when unpacking the control. Check for signs

of damage such as bent or dented panels, scratches, and loose or broken parts. If any damage is

found immediately notify the shipper.

• The DVP is shipped from the factory in an antistatic foam-lined carton. This carton should always be

used for transport of the DVP when it is not installed. Read the Electrostatic Discharge Awareness

page before handling the DVP.

• Check for and remove all manuals, connectors, mounting screws, and other items before discarding

the shipping box.

2.5.2. General Installation and Mounting Considerations

When selecting a location for mounting the DVP consider the following:

• Protect the unit from direct exposure to water or a condensation-prone environment.

• The DVP is designed for installation in a low vibration environment. If installed in vibration levels

above normal control room levels, the DVP should be vibration isolated from engine and generator

vibrations above 50 Hz. See Grounding Requirements above.

• Install the DVP5000/DVP10000 in an area where the operating temperatures will not exceed -40°C

to +70°C (-40°F to +158°F).

• Install the DVP12000 in an area where the operating ambient temperatures will not exceed -40°C to

+70°C (-40°F to +158°F) for 25A operation and -40°C to +55°C (-40°F to +131°F) for 28A operation.

The Woodward Actuator/Valve determines the DVP12000 operating current.

• The DVP is designed for rear panel mounting to a metal surface and adequate clearance around the

air intake and exhaust openings.

• The DVP can be mounted in any orientation with proper clearance provided to allow air flow. For

maximum thermal performance, the DVP must be mounted in a vertical orientation.

• Shield the unit from radiant heat sources.

• Allow adequate space around the unit for servicing and cable routing.

• Do not install near high-voltage or high-current devices.

• Install the DVP in an area where there is a protection from outside contamination.

• Installation Clearance: 6 inches on the top and 6 inches on the bottom in addition to proper airflow

ventilation in the cabinet for 100 CFM (or 2.8 cubic meters/minute) of unobstructed airflow per unit.

No clearance is required on the sides for cooling.

• Verify that cable lengths do not exceed lengths specified in the electrical I/O section of this manual.

• Refer to Technical Specifications for packaging heat load information

2.5.3. Wire Preparation and Connector Screw Torque Drive Recommendation

Woodward recommends that the following wire preparation and terminal block screw torque specifications

for all DVP input/output terminal blocks.

Note: Stranded wire is recommended.

2.5.4. Connector Kits

10 – 12 lb-in

(1.1 – 1.4 Nm)

The DVP is shipped with mating connectors for all input and output connectors. However, in some

applications where an extra set of connectors is needed, Woodward carries a connector kit as shown on

Table 2-2.

2.5.5. DVP 5000 and DVP10000 Configuration Options

The DVP10000 is the same as the DVP5000 with the addition of a boost module to increase power

temporarily to meet high performance actuator requirements. The DVP10000 package is slightly wider

than the DVP5000 to accommodate the boost module.

The DVP12000 is the same as the DVP10000 with a temperature derating option for higher output current

availability and the ability to operate with spring return actuators.

Additional Options:

• EXTERNAL SHUTDOWN feature is optionally certified to a SIL 3 level. The certified versions are

indicated on the front panel by DVP5000-S, DVP10000-S and DVP12000-S labels.

• Optional Ethernet Communication capability.

2.5.6. Terminal Locations

All terminals and connectors are located on the front panel of the chassis. Figures 2-2 and 2-3 show the

front panel and outline views. For EMC compliance, mount the DVP with low impedance bond to Earth

ground.

2.6 Fan Assembly Replacement

The fan assembly in the DVP is designed for field replacement if necessary. If one or both fans fail, an

alarm is generated.

The fans are a ball bearing type with a nominal airflow of 51.97 CFM (1.47m3/min) each.

A degraded fan can occasionally be identified by audible noise sounding like a low rumbling or roughness

from the bearings. In this case, it is advisable to replace the fan assembly at the earliest opportunity.
