VALUES
DEFAULT
SETTINGS
A
Mains rated V
Allows you to set the rated voltage of the mains.
0-600 [Vac]
400
B
Mains high V
You can set the high threshold voltage; if the voltage measured is
higher than this value (% of the rated voltage), the mains is considered
faulty and Genset starts the generator (in automatic mode).
100-200 [%]
115
C
Mains low V
You can set the low threshold voltage; if the voltage measured is lower
than this value (% of the rated voltage), the mains is considered faulty
and Genset starts the generator (in automatic mode).
0-100 [%]
85
D
Mains rated F
Allows you to set the rated frequency.
50-60 [Hz]
50
E
Mains high F
You can set the high frequency threshold; if the frequency measured is
higher than this value (% of the rated frequency), the mains is
considered faulty and Genset starts the generator (in automatic mode).
100-200 [%]
110
F
Mains low F
You can set the low frequency threshold; if the frequency measured is
lower than this value (% of the rated frequency), the mains is
considered faulty and Genset starts the generator (in automatic mode).
0-100 [%]
90
G
KR delay
You can set a delay time for the closure of the mains contactor. This
time starts from when the Genset
opens the generator contactor (software interlock function).
0-100 [s]
1
H
Mains OK
It is the delay time after which, if the mains returns within the limits set
(see parameters B, C, E, F), it’s considered stable and the mains
contactor is closed, then begins the stop phase of the generator (in
automatic mode).
0-600 [s]
10
I
Faulty mains
It is the delay time after which the mains is considered faulty, compared
with the limits specified in parameters B, C, E, F. This parameter is
used to filter any temporary instability of the mains. Increase this
parameter to avoid fast start/stop procedures due to mains flickering.
0-600 [s]
5
J
Phase sequence
Choose the sequence of the phases: R-S-T or T-S-R, or OFF
OFF-RST-TSR
RST
K
V Asymmetry
If the difference between the lower and the higher phase voltages is
greater than this parameter, the asymmetry alarm (if enabled) is shown.
0-100 [%]
10
L
KR protection
Parameter to enable the protection on mains failure. If On, the alarms
about the mains immediately open the mains contactor. If Off, the
mains contactor is opened only when the generator is ready.
On-O
ff
On
M
System type
You can set the type of system of the mains: three-phase, single-phase
or two-phase with neutral.
Three-phase
Single-phase
Two-phase+n
Three-phase
N
Cost for MWh
Set the cost for every Mega Watt per hour supplied by mains
1-999999
210
O
Start by KR
If On, if parameter “KR protection” is set to ON, every condition which
activates KR protection (phase inversion, feedback KR, asymmetry
alarm, etc...) also triggers an engine start with changeover on generator
until the mains returns ok.
