OPERATION
NP-DK50 DE-18_02-2019 15
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 (7) to other equipment must adhere
to local electrical regulations.
Fasten the electrical cord through the holder (10).
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 (1) to position “I”.
The compressor will be operational once it is put into operation. If there is no
air consumption at the output, the device switches to STANDBY mode. When
air consumption resumes, the compressor automatically switches on.
During operation, the device drains off the entrapped condensed water from
pneumatic circuits via automatic filter separators into a tank.
The following applies to device with additional equipment – WALL (5)
coupling:
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, 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.
During operation, the device drains the trapped condensed water from
pneumatic circuits via automatic filter separators into a separate tank.
