• 0-5 V pressure transducer:
• If a Pressure input is free on the Master controller, this input can be used to connect the pressure
transducer. If no input is free an additional I/O2 module (expansion module) is required.
• 4-20 mA pressure transmitter:
• To connect this type of sensor always an I/O2 module (expansion module) is required.
10.3 Automatic drain
Description
The automatic drain valve allows all air consumption to be avoided while the compressor is not running.
For machines with a built-in dryer, two water separation outlet may be provided, one up-line from the dryer
and the other on the dryer drain.
Overview
• There is no air loss due to the level detection system : an inductive sensor detects the level of water
and thus controls the opening of the electric bleed valve. A low level of condensation is also detected
in order to close the electric drain valve and to prevent compressed air from being wasted.
• This type of purge valve does not require any maintenance. The purge valve does not require the use
of the metallic intake filter that is usually installed on electronic purge valves to protect the solenoid
valve. The solenoid valve will not be damaged.
• Condensate discharge facilitated as condensates are not discharged under pressure facilitating
separation of the condensate oil and water phases.
