Step
Description
1
The blow-off valve (6) closes, resulting in a slow pressure rise in the air receiver (D).
This slow pressure rise is caused by a small air flow drawn in through calibrated bypass
holes in the unloader disc (6).
2
The pressure in the unloader pressure chamber (4) equals the pressure rise in the air
receiver (D).
3
Once the pressure in air receiver (D) has reached a preset value, the load / unload valve
(1) closes. This results in a gradual pressure decrease in unloader pressure chamber
(2) towards the compressor stage inlet pressure level.
4
The pressure difference in unloader pressure chambers (2) and (4) causes the unloader
plunger (3) to move upwards. This upward movement forces unloader disc (6) to open
the compressor stage inlet.
5
Air compression and air delivery resume.
2.5 Connectivity and ICONS
General
The machine comes with an ES4000T Touch controller which has an internal connectivity
device. The Touch controller allows read-out of a number of parameters of the machine on a
user login-protected web site called
ICONS
. The Touch controller has an integrated antenna.
Safety precautions
It is important to follow all regulations regarding the use of radio equipment, in particular
regarding the possibility of radio frequency (RF) interference. Please follow the safety
advice given below carefully.
• Respect restrictions on the use of radio equipment in fuel depots, chemical plants or
other explosive environments.
• Avoid operation close to inadequately protected personal medical devices such as
hearing aids and pacemakers. Consult the manufacturers of the medical device to
determine if it is adequately protected.
• Avoid operation close to other electronic equipment which may also cause interference if
the equipment is inadequately protected. Observe any warning signs and manufacturer
recommendations.
• Respect a distance from the human body of at least 20 cm (8 inch) during operation.
• Do not operate the device in areas where cellular modems are not advised without
proper device certifications. These areas include environments where cellular radio can
interfere, such as explosive atmospheres, medical equipment, or any other equipment
which may be susceptible to any form of radio interference. The modem can transmit
signals that could interfere with this equipment.
