Electrical Connection; First Operation - EKOM DK50 DS Manuel De L'utilisateur

OPERATION
The compressor must not be used for supplying air to the medical air
central distribution pipeline system.

Electrical connection

The compressor comes with a plug containing an appropriate
protective contact (ground.) Adhere to local electrical regulations. The
voltage
specifications on the data label.
The electrical cord must not be stressed or have any tension exerted
upon it, and must always be free.
 The socket must be accessible for safety reasons so that the equipment
can be safely disconnected from the power supply in case of an
emergency.
 The relevant current circuit must be protected.
 Connection of the ground connection (12) to other equipment must adhere
to local electrical regulations.
 Fasten the electrical cord through the holder (13).

First operation

 Make sure that the stabilizing screws used during transport were removed.
 Check that the connection to the compressed air supply is correct.
 Check for proper connection to the main power supply.
 Switch on the pressure switch (11) to position "I".
After the compressor is put into operation, it shall work in one of the following
modes depending upon the pressure level in the central distribution and upon
air consumption.
 STANDBY – When there is sufficient pressure in the central air distribution
line, the main switch is on and the POWER (8) indicator is on, the
compressor is idle. The device operates as a standby source of air as it
checks the pressure in the central air distribution line and, if the pressure
falls, the compressor switches on.
 When pressure is low in the central air distribution line, or if the device is
not connected to the central distribution line, the compressor is running. If
there is no air consumption at the outlet, the device switches to STANDBY
mode. When air consumption resumes, the compressor automatically
switches on.
 The working pressure in the air tank when the compressor is running is
maintained between the high and low pressure limits by the control unit.
After the high working pressure limit is reached, the compressor output is
connected to the exhaust (bypass) and the compressor stops supplying
compressed air to the air tank until as long as the pressure in the tank does
not drop below the low pressure limit.
