2. Safety information
2.1 General requirements
The flawless and safe operation of the SP400 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 SP400 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 SP400 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.

3. Technical information
3.1 Description
The SP400 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 SP400 includes many smart functions that can be fully programmed through menu driven
software using an integral keypad and LCD alphanumeric data. The absence of mechanical
linkages between valve stem and positioner, drastically simplifies the mounting procedure
and reduces the time required. Moreover the software has been designed to simplify
operations as much as possible: commissioning requires just assembling the SP400 to the
valve and pressing one button. The SP400 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.

4. Options
4.1 Pressure gauge block
An optional pressure gauge block (Figure 3) can be fitted onto the SP400 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.

5. Installation
5.1 Mounting the SP400 positioner - General information
Preliminary check of valve and actuator assembly - A preliminary check should be carried
out on the valve and actuator assembly prior to mounting and commissioning the SP400
positioner to confirm smooth movement of the stem. This can be performed by providing an
air supply directly from a filter/regulator to the actuator. The air supply pressure should be
gradually increased to progressively move the stem through its full travel. Any friction or
jerky movement of the stem should be investigated prior to commissioning the SP400.
5.1.1 The SP400 is supplied with a NAMUR standard fixing kit for linear actuators (yoke
or pillar) or with a VDI / VDE 3845 compliant mounting kit for rotary actuators.
5.1.2 The SP400 has an enclosure rating of IP65 and should be installed in a location that
will not exceed its ambient temperature limits of -10°C minimum and +80°C maximum.
5.1.3 Before fitting and commissioning the SP400 positioner ensure that the valve and
actuator are correctly assembled. Refer to the valve and actuator Installation and
Maintenance Instructions for details.

5.2.1 Loosely attach the magnet bracket (2) to the valve / actuator connector (refer to
Figures 4 and 5). Be sure it is positioned horizontally (as shown in Figure 5).

5.2.2 Slide the bracket (2) to the left or to the right (Figure 6) till the correct position is
achieved. If you’re using a Spirax Sarco actuator the correct position is impressed
on the magnet bracket (Figure 7).
5.2.3 If you’re not using a Spirax Sarco actuator, slide the bracket till the distance 'A'
between the center of the magnet and the inner side of the mounting plate is 25 mm
(Figure 8).
