too rough or the stage sizes
may be oversized.
No stages may be switched in
the manual mode.

Stages are locked, because

U-Alarm is active or the
discharge time of the stages
is still running.

Stages have been switched
off due to the THD-U, THD-I
or TEMP2 alarm and have
been locked for 30 min.

LIFO, combi filter or FIFO
has been set as control
algorithm.

Check if the measuring
voltage is within the valid
range and if the U alarm is
signalled, enter the set
nominal voltage again, if
necessary.

After a restart of the control,
wait for the set discharge
time lock and try again.

If stages have been
switched off due to the
THD-U, THD-I or TEMP2
alarm, wait for the blocking
time of 30 min.

In order to test the stages,
use the control algorithm
Best Fit (
“AUTO”)
(SETUP/311).

ALARM
(Stage Power Loss)
The affected stages are not
switched on anymore resp.
cannot be switched on in
manual operation.

Stage alarm stage power
loss:

The ratio of the current to the
original stage size has fallen
below 75% (power loss).


Affected stages have
been set to
“FOFF” and are
locked for as long as the
alarm is active.

Check the power loss of the
affected stages (relation of
the current to the original
stage size), change the
affected stages, if
necessary, and manually
enter the stage sizes again
in order to reset the alarm.
Then, the stage type of the
stages can be set back to
“AUTO”.
TEMP1 limit value has been
exceeded, but the switching
output for the fan does
NOT
switch on.

The switching output for the
fan is used as 7
th
resp. 13
th
stage output.

Check the settings for the
fan switching output:

SETUP/406 may be set to
“YES” 
switch to
“NO”.
Switching output for the fan
switches on (stage symbol 13 is
displayed), even though TEMP1
limit value has
NOT been
exceeded.

Use the switching output for
the fan as 7
th
resp. 13
th
stage
output.

Check the settings for the
fan switching output:

SETUP/406 may be set to
“YES” 
switch to
“NO”.
Switching output of stage 13 is
not used by the control resp. it is
not possible to switch it in
manual operation, because
stage 13 cannot be selected.

Switching output fan is set as
fan switching output (default).

Check the settings for the
fan switching output:

SETUP/406 may be set to
“NO” 
switch to
“YES”.

Check the stage type for
the stage output 13; switch
to
“AUTO”, if necessary.

Is the root connection of the
fan switching output
connected to the supply
voltage as illustrated on the
