POSITIONER IS SUPPLIED BY ACTUATECH S.P.A. WITHOUT BEING CALIBRATED. THE SETTING IS NOT RESPONSIBILITY OF ACTUATECH.
DESCRIPTION Cam electro-pneumatic positioner is particularly suitable for proportional working of both GD and GS actuators.The positioner is connected to the actuator by means of a mounting kit fixed to the actuator. A regulating electric signal, given by a thermostat, viscometer, pressure gauge, etc. ..., is sent to the positioner which, according to this signal, regulates the valve opening and closing angles.Clockwise and anticlockwise actions can be changed without using additional components, but simply turning the cam over and reverting the actuator connections.
TECHNICAL FEATURES - Supply: dry instrument air 5μ - Electric input signal: 4÷20 mA - 2 manometers: 1 for air supply, 1 control signal. - Input resistance: 235 ± 15 Ohm (4÷20 mA cc) - Pneumatic connections: 1/4” NPT - Eletrical connections: M20 x 1,5 - Linearity: < ±2% - Sensitivity: < 0,5% of the range - Air consumption: from 5 Nl/min. (P=1,4 bar) to 11 Nl/min. (P=4 bar) - Working temperature: from -20°C to +80°C - Protection: IP65 (according to IEC Pub.60529)

NOTES Pneumatic and electro-pneumatic positioners are supplied up on request adjusted and are mounted using covered aluminium pipes and rapid connectors.
Adjustment A = 0° - 90°: • 4mA control signal: closed position • 20mA control signal: opened position. Adjustment D = 90° - 0°: • 4mA control signal: opened position • 20mA control signal: closed position.
For any other information, see the use and maintenance manual.
