Changing the Filter in Automatic Mode
If the FS-21 is in Automatic operating mode (yellow LED in the Hand key is OFF) and it is
running with two filters in half-duplex mode, a filter can be changed after pressing the two
Arrow keys simultaneously for 2 seconds. The filter which is ready in standby is put into
operation and the filter previously in operation reverts to standby. The counters of the
respective filter are retained.

Operation
Activate Hand operating mode by pressing the Hand key. The yellow LED in the key lights
up. If Hand operation is activated while a filter is actually regenerating, the regeneration
step currently being performed is not automatically switched to the next step when
completed. The ongoing regeneration time is incremented.
Note:
If the FS-21 is in Hand operating mode, regeneration is no longer started auto-
matically.

the filter currently in operation can be started by pressing the 'Down' key for approx 2
seconds.
11.4
Skip to Next Regeneration Step in Hand Operation
When the filter is regenerating, pressing the ‘Down' key for approx 2 seconds causes the
system to skip to the next step.

Fault Messages
The following fault message could appear:
This message appears when the regeneration counter has reached the configured
number of regenerations or the service interval is reached (Service after xxx days). This
fault message can only be acknowledged when a reset is executed under
'Parameter/Service/service reset'.
If a fault occurs, the red LED in the Acknowledgement key flashes. After pressing the Ack-
nowledgement key, the red LED lights up continuously. Each time a new alarm is received,
the LED starts to flash again. The LED goes out when the cause of the fault is cleared.
