4.2 Supply Pressure Condition
Ø Dry air with at least 10℃ lower than ambient temperature.
Ø Avoid dusty air. Positioner’s inner filter can only filter 5 micron or larger.
Ø Avoid oil.
Ø Comply with ISO 8573-1, Class 2 (solid particle size and density and oil content).
Ø Supply pressure range is 0.14~0.7 MPa (1.4~7 bar)
Ø Set air filter regulator’s pressure level 10% higher than actuator’s spring range pressure.
4.3 Piping Condition
Ø Ensure inside of pipe is clean of obstructions.
Ø Do not use pipeline that is squeezed or shows any type of damages.
Ø Pipeline should have more than 6mm of inner diameter (10mm outer diameter) to maintain flow
rate.
Ø The length of pipeline system should not be extremely long. Longer pipeline system may affect
flow rate due to the friction inside of the pipeline.
4.4 Connection – Actuator
4.4.1 Single acting actuator – Figure 3301 & 3303
Singe acting type positioner is set to use OUT1
port. OUT1 port should be connected with the
supply pressure port of the actuator when using
single acting type of spring return actuator.
4.4.2 Double acting actuator – Figure 3302 & 3304
Double acting type positioner is set to use OUT1 and
OUT2 port. As input signal increases, the supply
pressure will be supplied through OUT1 port.
