DEL.AFTER
START GEN.
Delay after generator start
-
This parameter defines the time between generator starts.
If a start signal is sent and the generator does not deliver any
voltage within the set time, alarm A13 or A14 Generator 1/2 not
available is triggered. After that, transfer to a second generator (if
configured) takes place.

EJP START
DELAY
EJP start delay
– Delay between the EJP start signal and the actual start signal
at the generator.

P08.12
EJP SWITCH
DELAY
EJP changeover delay
– Delay in changing over the load from the priority to the second-
ary source in the EJP and SCR mode.
min 5 0-240
P08.13
SWITCH LOCK
Locking of the EJP return changeover
– If set to ON, the load in the modes EJP, EJP-T and SCR is not
switched back to the priority source when a fault occurs in the
generator, but only when the signals at the EJP inputs enable the
changeover.

EN. IN-PH
TRANSITION
IN-PHASE Transition
settings
– This parameter can be used to enable IN-PHASE transition, i.e.
the ATC waits until both sources fulfill the conditions of parame-
ters P08.15, P08.16 and P08.17.
OFF: The transfer takes place with open transition at an unde-
fined time. One source is only closed after the other has been
opened.
IN-PHASE: With this setting, you can toggle between synchro-
nized sources in the open transition. The ATC checks for syn-
chronism of the sources. If the state of synchronism is present on
the return, the transfer to the other source is only performed
when the previous source has been opened.
SEL: Must be selected if IN-PHASE transition is only allowed to
take place in certain situations as defined under P08.25.

MAX DELTA V
Maximum Delta V
– This parameter defines the maximum tolerated voltage devia-
tion between two sources during synchronization. The deviation
is specified as a percentage.

P08.16
MAX DELTA
Hz
Maximum Delta Hz
– This parameter defines the maximum tolerated frequency devi-
ation between two sources during synchronization. The deviation
is specified in Hz.
Hz 0.5 0.0 - 10.0
P08.17
MAX DELTA
Phi
Maximum Cos Phi
-
In the case of a synchronization, this parameter defines the
maximum tolerated deviation between the displacement angle
cos phi of the two sources. The deviation is specified in degrees.
