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.

3. Technical information 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.

4. Options 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.

4.2 Retransmission and travel switches option board An option board can be fitted in the positioner to add valve position retransmission functionality and software travel switches functionality. The board generates a 4-20 mA current signal which represents the actual valve position. Moreover 2 output terminals are available to be configured as software travel switches.

Rotate the mainboard and insert the option board (as shown in Figures 6, 7, 8 and 9). Rotate the mainboard to the initial position, fix it with the 4 screws, close the positioner and switch on the power supply and air supply. Fig.

4.3 External power supply option board The SP500 can host an option board for 24 V power supply. It’s a 4 wiring diagram: 2 wires for current loop and 2 wires for power supply through a 24 V external voltage. This reduces dramatically the voltage drop on the current loop. The drop is 7 V when the unit is powered by the loop (2 wires), it falls to 1 V when the 4 wires configuration is used.

Rotate the mainboard and insert the option board (as shown in Figures 12 and 13). Fig. 12 Fig. 13 Remove the Jumper J4 (Figure 14). Fig. 14 IM-P343-35 CH Issue 1.

Fig. 15 Insert the power supply option board. Collocate Jumper J4 as shown in Figures 15 and 16. Fig. 16 Rotate the mainboard to the initial position, fix it with the 4 screws, close the positioner and switch on the power supply and air supply. Once the option board is mounted, the positioner shall be powered according to the 4 wires connection diagram, refer to Section 6.2.3, ‘4 wires electrical connection’.

5.3.2 Adjust the magnet orientation as illustrated in Figures 36 and 37 and tighten the bolt to fix the magnet into position. There should be a distance of between 5 and 14 mm between the magnet and the positioner. Refer to Figure 36 for actuator with clockwise rotation. Refer to Figure 37 for actuator with anti-clockwise rotation.
