Description
EJP start delay
– Delay between the EJP start signal and the
actual start signal at the generator.
EJP changeover delay
– Delay in changing over the load from the
priority to the secondary line in the EJP and
SCR mode.
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
line when a fault occurs in the generator, but
only when the signals at the EJP inputs enable
the changeover.
– When this parameter is enabled and the
switching device does not close successfully
(no feedback on presence of opening com-
mand), not only the corresponding feedback
alarm (A03 or A04) is triggered, but changeover
to the secondary line is also controlled.
OFF = Function disabled
1 = Check Line 1
2 = Check Line 2
1+2 = Check both lines.
Duration of the opening pulse of the undervolt-
age release for the opening of the switching
devices
– If an additional undervoltage release is used,
this parameter defines how long the output is
opened with the undervoltage release function
Line 1 or 2 (see chapter Table of functions of
the digital outputs (Page 112))
Delay between opening pulse of the undervolt-
age release and spring reload command
– This parameter defines after which time (after
parameter P05.18 has elapsed) an opening
command to load the springs is sent to the
switching device.
