SP500 Electropneumatic Smart Positioner

2.1 General requirements

The flawless and safe operation of the SP500 positioners is reliant on proper transportation, storage,

installation and commissioning by qualified personnel, proper use and careful maintenance.

Prior to installing, using or maintaining the positioner, consideration should be given to:

-The working environment.

-Safe access.

-Lighting.

-Pipeline fluid hazards.

-Temperature.

-System isolation.

-Location.

The SP500 positioner should be mounted with sufficient space to allow opening of the hinged cover

and to provide access for electrical and air connections. When fitting to an actuator, ensure that

the positioner will not be exposed to an ambient temperature outside the range of -10 °C to +80 °C.

The positioner enclosure is rated to IP65 (see BS EN 60534-1 1998).

2.2 Electrical safety requirements

The SP500 is a class III product which must only be powered from Safe Extra Low Voltage (SELV)

sources whether by virtue of a 4 - 20 mA control signal or from a separate power supply. Similarly

all signal circuits connected to an options board must operate within the confines of SELV systems.

All associated wiring must be separated from other wiring containing hazardous voltages.

2.3 Electromagnetic compatibility

The product complies with the Electromagnetic Compatibility Directive 2004/108/EC according to:

- EN 61326-1: 2006

- EN 61326-2-3: 2006

- EN 55011: 1998 + A1: 1999 + A2: 2002

- EN 61000-4-2: 1995 + A1: 1998 + A2: 2001

- EN 61000-4-3: 2006

- EN 61000-4-4: 2004

- EN 61000-4-5: 2006

- EN 61000-4-6: 2007

- EN 61000-4-11: 2004

This product may be affected by interference if:

- The product or its wiring is located near a radio transmitter. The actual separation necessary

will vary according to the power of the transmitter.

- Cellular telephones or mobile radios are used within approximately one metre of the product

or its wiring.

- The wiring is routed alongside power cables subject to high voltage transients or current surges.

SP500 Electropneumatic Smart Positioner

3.1 Description

The SP500 smart valve positioner is loop powered from a 4 - 20 mA input signal to provide accurate adaptive

positional control of pneumatic actuated linear and quarter turn valves.

Precise control is maintained through valve position feedback that automatically varies the pneumatic

output pressure to overcome the effects of stem friction and flow forces to maintain desired valve position.

Indication of valve position is provided through a continuous digital display of % travel. Valve position

feedback is retrieved by means of a non contact technology based on Hall effect. The pneumatics are based

on piezovalve technology - Therefore, high resolution, high reliability, vibration insensitivity and extremely

low air consumption is guaranteed at steady state.

The SP500 includes many smart functions that can be fully programmed through menu driven software

using an integral keypad and LCD alphanumeric data. Valve commissioning is simplified through an

autostroke routine and display of programming status, software travel switch status, mA input signal and

valve diagnostics data. Moreover, the absence of mechanical linkages between valve stem and positioner,

drastically simplifies the mounting procedure and reduces the time required. The SP500 is supplied with a

NAMUR standard mounting kit for attachment to yoke or pillar mounted actuators. For quarter turn valves,

a mounting kit compliant to VDI/VDE 3845 is supplied.

The SP500 smart valve positioner supports optional expansion to include the HART®communication protocol,

enabling complete configuration using a PC or handheld device.

4.1 Pressure gauge block

An optional pressure gauge block (Figure 3) can be fitted onto the SP500 positioner which includes two

pressure gauges indicating air supply pressure and output air signal pressure to the actuator. The pressure

gauge block can be retrospectively fitted using 2 off M5 socket head screws. Ensure that the gauge block

air connection 'O' rings are correctly located before tightening.
