Pneumatic Connection - ABB PositionMaster EDP300 Operating Instruction

Pneumatic connection

ange from one to two columns
IMPORTANT (NOTE)
The positioner must only be supplied with
instrument air that is free of oil, water, and dust (in
the gas exhaust with dried natural gas).
The purity and oil content must meet the
requirements of Class 3 according to DIN/ISO
8573-1.
NOTICE – Potential damage to parts!
Contamination on the air pipe and positioner can
damage components.
Dust, splinters, and any other particles of dirt must
be blown off the pipe before it is connected.
All pneumatic piping connections are located on the right-
hand side of the positioner. G1/4 or 1/4 18 NPT tap holes are
provided for the pneumatic connections. The positioner is
labeled according to the tap holes available.
We recommend that you use a line with dimensions of 12 x
1.75 mm. The level of supply air pressure required to apply
the actuating force must be adjusted in line with the output
pressure in the actuator.
The working range for the positioner is between 1.4 ... 10 bar
(20 ... 145 psi).

Connect the connections according to their labeling:
Labeling Pipe connection
SUP / ZUL IN Air supply, pressure 1.4 ... 10 bar (20 ... 145
psi)
Y1 / OUT1 Actuating pressure for actuator
Y2 / OUT2 Actuating pressure for actuator (2nd connection
with double-acting actuator)
NOTICE – Potential damage to parts!
Pressure above 10 bar (145 psi) can damage the
positioner or actuator.
Provisions must be made (e.g., using a pressure
regulator) to ensure that the pressure does not
rise above 10 bar (145 psi), even in the event of a
fault.
