2. Safety information
2.1 General requirements
The flawless and safe operation of the SP200 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 SP200 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 SP200 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 89/ 336 EEC
by meeting standards EN 5008-1 (Emissions) and EN 50082-2 (Industrial Immunity).
This product may be affected by interference above the limits within EN 50082-2 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.

2.4 Installation for hazardous areas and certification
- General information
SP200 Smart Positioner is available for Intrinsic Safety applications, model identification
is SP200is.
In case of use in hazardous areas with danger of explosion, it must be verified that the
identified type of positioner fits for the classification of the zone and for the presence of
flammable substances in the plant.
Model SP200is is certified by EC-type Examination Certificate N. IMQ 07 ATEX 011- EC
Directive ATEX 94/9/CE with following classification:
II 2GD
and protective system:
Ex ia IIC T6 / Ex iaD 21 T85°C (Tamb –20/+40°C)
Ex ia IIC T5 / Ex iaD 21 T100°C (Tamb –20/+65°C)
Ex ia IIC T4 / Ex iaD 21 T135°C (Tamb –20/+80°C)
2.4.1 Safety data definitions
Group II: surface plants
Category 2: fit for zone 1 Gases – zone 21 Dusts: an area in which an explosive mixture is
likely to occur in normal operation
G (Gas): fit for explosive gases
D (Dust): fit for flammable dusts
Protection system (Intrinsic Safety): Ex ia for Gases
Ex iaD for Dusts
IIC : gas group IIC including Hydrogen and Acetylene
Temperature classification T6 (Maximum surface temperature = 85°C)
Temperature classification T5 (Maximum surface temperature = 100°C)
Temperature classification T4 (Maximum surface temperature = 135°C)
IM-P343-29 CH Issue 56
2.4.2 Electrical connections for IS.
For installation in classified areas it is necessary to foresee the use of certified associated
apparatuses (e.g. safety barriers), with output electrical characteristics compatible with
the maximum input parameters (ref. to Name-plate) of the certified SP200is positioner:
Electrical input parameter of SP200is
Circuit Ui(V) Ii (mA) Pi(mW) Ci(nF) Li(mH)
Supply 30 100 650 2 -
Switch 1&2 15 25 65 12 -
Retransmit 30 100 650 15 -
Evaluation of the system constituted by the associated apparatus, SP200is positioner
and connection cables must be done by experienced personnel only and must match the
requisite of the standard EN 60079-25 for intrinsically safe systems.
In Section 6 there is an example drawing of electrical connections for Intrinsically Safe
applications.
A drawing of the Name-plate is shown below
A copy of EC-Type ATEX Certificate is in 'Section 13 - Certification'.

3.1 Description
The SP200 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. Therefore, high resolution, high reliability and vibration insensitivity are
guaranteed.
The SP200 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 SP200 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 2) can be fitted onto the SP200 positioner
which includes two pressure gauges indicating air supply pressure and output air signal
pressure to the actuator. For double action valves the gauge block includes 3 pressure gauges
indicating: air supply pressure, output 1 air signal and output 2 air signal. The pressure gauge
block can be retrospectively fitted using 2 off M5 Allen screws. Ensure that the gauge block
air connection 'O' rings are correctly located before tightening.
