Description
Type of switching device
– This parameter specifies whether the programmable
Open / Close outputs must be continuously active (application
with contactors or with switching devices without feedback) or
operating in pulse mode, i.e. enabled until the switching device is
located in the correct position. If the pulse mode is selected, the
command is extended for a certain time (see P07.n.04 and
P07.n.05), even after the position has been reached.
Changeover response
– This parameter defines the general conditions for a changeo-
ver.
A choice is made between OBP (Open before presence) and
OAP (Open after presence).
Max. time in which the load is without power (response delay
alarm A07)
– If both power supplies are simultaneously unavailable for long-
er than the time set in P08.03, alarm A07 is triggered.
Inhibits the automatic return to the priority source
– If this parameter is enabled, the supply is not automatically
switched back from the secondary source to the priority source
when it becomes available again. Instead, it must be switched
back manually.
OFF – Disabled
ON – Lock enabled
Delay of generator start
- Delay in starting the generator if the priority source fails to meet
set limits. If this value is set to OFF, the starting cycle begins
simultaneously with the opening of the priority source breaker.
Generator start interval
- These parameters permit a time-controlled rotation in the G/G
application by toggling the priority between the two generators.
P08.06 specifies the rotation interval of the two generators.
This enables a rotation between generators to be programmed,
i.e. the load can be switched from one to the other at regular
intervals, with the purpose of sharing out the generator work
equally.
Time of generator start
- The time of day at which the rotation is performed is specified
by P08.07 and P08.08. If the rotation interval is greater than 24
hours, the rotation is performed at the specified time every n
days. If it is less than 24 hours, the rotation is performed at the
specified time and at the respective intervals. If, for example, the
time is specified as 12:30 and the rotation is every 6 hours, one
rotation will take place at 12:30, one at 18:30 the next at 0:30 etc.
