This is the rated value of current
transformers at the genset CT inputs.
500 All transformers must have the same
rating. The secondary of the
transformer will be 5 Amps.
This is the rated value of current
transformers at the mains CT inputs.
500 All transformers must have the same
rating. The secondary of the
transformer will be 5 Amps.
This is the voltage transformer ratio.
This value will multiply all voltage and
1.0
power readings. If transformers are not
used, the ratio should be set to 1.0
The nominal value of genset and mains
230 voltages. Voltage limits are defined by
reference to this value.
The nominal value of genset and mains
50 frequency. Frequency limits are defined
by reference to this value.
When secondary voltage is selected,
this is the nominal value of genset and
120
mains voltages. Voltage limits are
defined by reference to this value.
When secondary frequency is selected,
this is nominal value of genset and
60
mains frequency. Frequency limits are
defined by reference to this value.
When tertiary voltage is selected, this is
the nominal value of genset and mains
120
voltages. Voltage limits are defined by
reference to this value.
When tertiary frequency is selected, this
is nominal value of genset and mains
60
frequency. Frequency limits are defined
by reference to this value.
If one of the mains phases goes under
this limit, it means that the mains are off
V-20% and starts the transfer to the genset in
AUTO mode. The value is defined with
reference to Nominal Voltage.
If one of the mains phases goes over
this limit, it means that the mains are off
V+20% and starts the transfer to the genset in
AUTO mode. The value is defined with
reference to Nominal Voltage.
If at least one of the mains phase
voltages goes outside of the limits
1 during this timer, it means that the
mains are off and it starts the transfer to
the genset in AUTO mode.
