RANGE OF
VALUES
DEFAULT
SETTINGS
A
GE rated V
Rated voltage of the generator.
0-600 [VAC]
400
B
GE high V
You can set the high threshold voltage; if the voltage measured is higher than
this value (% of the rated voltage), the generator is considered faulty and
Genset shows the “high GE voltage” alarm.
100-200 [%]
115
C
GE low V
You can set the low threshold voltage; if the voltage measured is lower than
this value (% of the rated voltage), the generator is considered faulty and
Genset shows the “low GE voltage” alarm.
0-100 [%]
85
D
GE rated F
Rated frequency of the generator.
40-70 [Hz]
50
E
GE high F
You can set the high threshold frequency; if the frequency measured is higher
than this value (% of the rated frequency), the generator is considered faulty
and Genset shows the “high GE frequency alarm”.
100-200 [%]
110
F
GE low F
You can set the low threshold frequency; if the frequency measured is lower
than this value (% of the rated frequency), the generator is considered faulty
and Genset shows the “low GE frequency alarm”.
0-100 [%]
90
G
Rated current
You set the nominal operating current of the generator.
0-9999 [A]
100
H
Imax overload
You set the maximum overload admitted on the generator. If exceeded, an
alarm message is shown.
0-1000 [%]
200
I
Imax short circuit
You set the value that permits to consider a short circuit on the generator. If
exceeded, related alarm message is shown.
0-1000 [%]
300
J
KG delay
You can set a delay time for closing the generator contactor.This time starts
from when the Genset opens the mains contactor (software interlock
function).
0-100 [s]
1
K
GE Ok delay
It is the delay time over which if the voltage and frequency are within limits
(parameters B, C, E, F), the generator is considered stable and its contactor
is closed.
0-65535 [s]
5
L
CT ratio
It sets the ratio of Current Transformers to read the current value (example:
CT 100/5A, you must set it at 20, because 100: 5 = 20).
0-10000
20
M
System type
You can set the type of system of the generator: three-phase, single-phase or
two-phase with neutral.
Three-phase
Single-phase
Two-phase+n
Three-phase
N
Set kWh
Here you can set the initial value of the kWh.
0-10E+8 [kWh]
0
O
Phase sequence
Choose the sequence of the phases: R-S-T or T-S-R, or OFF
OFF-RST-TSR
RST
P
Asymmetry
If the difference between the lower and the higher phase voltages is greater
than this value, the asimmetry alarm (if enabled) is shown.
0-100 [%]
10
Q
GE Filter
Insert a 5-levels software filter on eventual disturbs on generator voltage and
frequency. It can be set from 0 (no flitering) to 5 (high filtering), to avoid
accidental opening of the generator contactor.
0-5
1
R
Neutral
Set if the system is with (On) or without (Off) neutral.
On-O
ff
On
S
Single CT
If On, line 2 and line 3 load currents are the same value of line 1. In this case
it is possible to calculate all 3-phase load measurements (kW, kVA, kVAR,
PF) using a single current transformer. This feature is intended to be used
only with balanced three-phase loads.

T
Cost for MWh
Set the cost for every Mega Watt per hour supplied by the generator.
