Description
Genset Current
Transformer Primary
Amp 1 5000 500
This is the rated value of current
transformers at the genset CT inputs.
All transformers must have the same
rating. The secondary of the
transformer will be 5 Amps.
Mains Current
Transformer Primary
Amp 1 5000 500
This is the rated value of current
transformers at the mains CT inputs.
All transformers must have the same
rating. The secondary of the
transformer will be 5 Amps.
Voltage Transformer
Ratio
- 0 5000 1.0
This is the voltage transformer ratio.
This value will multiply all voltage and
power readings. If transformers are not
used, the ratio should be set to 1.0
Nominal Voltage V-AC 0 300 230
The nominal value of genset and mains
voltages. Voltage limits are defined by
reference to this value.
Nominal Frequency Hz 0 500 50
The nominal value of genset and mains
frequency. Frequency limits are defined
by reference to this value.
Nominal Voltage-2 V-AC 0 300 120
When secondary voltage is selected,
this is the nominal value of genset and
mains voltages. Voltage limits are
defined by reference to this value.
Nominal Frequency-2 Hz 0 500 60
When secondary frequency is selected,
this is nominal value of genset and
mains frequency. Frequency limits are
defined by reference to this value.
Nominal Voltage-3 V-AC 0 300 120
When tertiary voltage is selected, this is
the nominal value of genset and mains
voltages. Voltage limits are defined by
reference to this value.
Nominal Frequency-3 Hz 0 500 60
When tertiary frequency is selected, this
is nominal value of genset and mains
frequency. Frequency limits are defined
by reference to this value.
Mains Voltage Low Limit % V-100 V+100 V-20%
If one of the mains phases goes under
this limit, it means that the mains are off
and starts the transfer to the genset in
AUTO mode. The value is defined with
reference to Nominal Voltage.
Mains Voltage High Limit % V-100 V+100 V+20%
If one of the mains phases goes over
this limit, it means that the mains are off
and starts the transfer to the genset in
AUTO mode. The value is defined with
reference to Nominal Voltage.
Mains Voltage Fail Timer sec 0 10 1
If at least one of the mains phase
voltages goes outside of the limits
during this timer, it means that the
mains are off and it starts the transfer to
the genset in
AUTO mode.
