9.4.9 P09 - Control thresholds of the source lines
This menu is divided into 2 sections for the limit thresholds of Source 1 (SLC1; SLC =
Source Line Control) and the limit thresholds of Source 2 (SLC2).

MIN. VOLTAGE
LIMIT
Limit threshold for minimum trip voltage
– The first two parameters P09.n.01 and P09.n.02 specify the
minimum voltage threshold limit and the related hysteresis upon
restoration of power. P09.n.02 cannot be set to a lower value
than P9.n.01. P09.n.03 defines the intervention delay of this safe-
ty mechanism

LIMIT
Limit threshold for maximum trip voltage
– The first two parameters P09.n.04 and P09.n.05 specify the
maximum voltage threshold limit and the related hysteresis upon
restoration of power. P09.n.05 cannot be set to a higher value
than P09.n.04. If P09.n.04 is set to OFF, the maximum voltage
measurement is disabled. P6.06 specifies the maximum voltage
intervention delay.

PRESENCE
DELAY
Delay, if the source is back within the specified limit (and the
other source is not available).
– Used if the other source is not available. The parameter defines
the time after which the source is regarded as stable (if the limit
thresholds can be observed). The Source 1/2 Availability LED will
show a continuous light after this time.
Normally this time is shorter than P09.n.08, as the load is non-
energized, and voltage needs to be supplied urgently.

P09.n.08
LINE OK DELAY
Delay, if the source is back within the specified limit (and the
other source is available).
– Used if the load can be connected to the other source. The
parameter defines the time after which the source is regarded as
stable (if the limit thresholds can be observed). The Source 1/2
Availability LED will show a continuous light after this time.
Normally this time is longer than P09.n.07, as the load is being
energized, and it is possible to wait longer before assuming a
stable voltage has been restored

PHASE
FAILURE
THRES
Phase failure threshold
– Voltage threshold below which a phase loss intervention oc-
curs. This is usually set lower than the minimum voltage limit
threshold. In addition, a shorter delay is assumed for it. The delay
for the phase failure is specified by P09.n.10.
