In the event of a fault
In the event of an emergency or if a safety-relevant disruption occurs (e.g.
escaping compressed air, defective component), immediately close the
compressed air supply line and set the ON/OFF switch of the dryer to
0
in order
to disconnect it from the power supply. Afterwards depressurise the dryer (see
also chapter
,
page 37).
Then proceed as follows:

Look up possible cause of the fault, and how to remedy the same, in the

Repeat the start-up procedure.
Changing cycle mode
When can I change cycle mode?
If the dryer has been successfully commissioned and is equipped with one of the
following options:
compressor synchronisation
or
dewpoint-sensing control
it can be set to
economy cycle
mode.
When should I change cycle mode?
Cycle changes should be made during the pressure build-up phase and prior to
switchover; during this phase, the pressure in both chambers is just below
operating pressure so that a fast pressure build-up is prevented when the
chambers are switched.
During this period, only the adsorption LED is on in the diagram, and the digital
display shows step 4 or step 9 for the duration of 1 minute (see logic control
diagram; not displayed with dewpoint sensing).
Which cycle modes can I choose?
If the dryer is connected to a
compressor synchronisation system
and is
equipped with the
dewpoint-sensing control
option, these two optional devices
can only started together. The compressor synchronisation has thereby
precedence over the dewpoint-sensing control.
With compressor synchronisation
If compressor synchronisation is enabled, the dryer can only be operated in
conjunction with the compressor. As soon as the compressor is switched off, the
dryer is automatically set to standby mode.
In standby mode, the control system remains on, and the dryer is ready for the
next switchover, which is made as soon as the compressor is switched on.
