5.1.5 Automatic re-start
Danger
In this operating mode, the compressor may start
automatically at any time and after an unlimited -
length of power loss.
Always fit the compressor with warning signs, lock
the room containing the compressor and instruct
your staff.
Fit the main switch specified by EN60204 and fit the
appropriate warning signs on it.
After a power loss that has not exceeded the preset
time, the unit can re-start automatically.
The settings needed must be undertaken in the
[
CONTROL

sub-menu. The relevant menu
items are:
AUTO
RESTART
OFF
POWER
LOSS
TIME
Xs
START-UP
DELAY
Xs
Use the
AUTO
RESTART ON
menu item to activate the
automatic re-start.
You can state the time for which a power loss may last
and after which the compressor is to automatically start
up in the
POWER
LOSS
TIME
menu item. The time can
be set within a period of 3 - 999 seconds. If the power
loss lasts longer than the time you have set, the unit
does not automatically re-start. The
POWER
LOSS
. fault
message then appears on the display
You can also program a start-up delay of 1 – 60 seconds.
This is set in the
START-UP
DELAY
menu item and
ensures a staggered start-up if the unit features several
compressors. This in turn ensures that the power supply
is not loaded unnecessarily.
