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
-
