INSTALLATION
2-bit pressure select
If a 2-bit Setpoint is selected, PIN2 (the analog setpoint input) will become the DIGITAL INPUT 2, and PIN4
(the digital output) will become the DIGITAL INPUT.

PNEUMATIC CONNECTION
The air flow direction is from connection 1 to 2.
1
Inch screw connections (pipe threads) are to be used.
Each screw connection must be lined with a fitting plastic sealing ring.
Teflon sealing tape and hemp may not be used, because some of these materials may end up inside the valve.
A suitable silencer is to be used at port (3). Depending on the type of silencer used, the time required for the air
to be released may be extended.
The cross-section of the pneumatic lines must be adjusted to the nominal diameter of the valve. The output line
(2) should have a cross-section greater than or equal to the input line (1).
The supply pressure must always be less than the value specified in the table in section 3, but it must always be
greater than the desired output pressure.

INFORMATION ON THE FACTORY SETTINGS
-
Output pressure 0 bar with a setpoint of 0 volts
-
Pressure range: 3-bar device = 3 bar at 10 V / 20 mA
-
Minimal hysteresis
-
The control parameters, the zero point and the pressure range are factory-set.
Set of parameters: factory settings
Zero point: 0%
Pressure range: 100%
Setpoint ramp: none
Shut-off point: ONE; with a target value of less than 0.5%, the air will be released from the valve
Control system: PID
