CL Setting range Description
[Default]
2 50 to 650000 V Some generator applications may require the use of potential transformers to
facilitate measuring the voltages produced by the generator. The rating of the
[400 V]
primary side of the potential transformer must be entered into this parameter.
If the generator application does not require potential transformers (i.e. the
generated voltage is 480 V or less), then the generated voltage will be
entered into this parameter.
2 50 to 480 V Some generator applications may require the use of potential transformers to
facilitate measuring the voltages produced by the generator. The rating of the
[400 V]
secondary side of the potential transformer must be entered into this param‐
eter.
If the generator application does not require potential transformers (i.e. the
generated voltage is 480 V or less), then the generated voltage will be
entered into this parameter.

Notes
WARNING: Only connect the measured voltage to either the 120 Vac or the
480 Vac inputs. Do not connect both sets of inputs to the measured system.
The control unit is equipped with dual voltage measuring inputs. The voltage
range of these measurement inputs is dependent upon input terminals are
used. This value refers to the secondary voltages of the potential trans‐
formers, which are directly connected to the control unit.
2 1 to 32000 A/x The input of the current transformer ratio is necessary for the indication and
control of the actual monitored value.
[500 A/x]
The current transformers ratio should be selected so that at least 60 % of the
secondary current rating can be measured when the monitored system is at
100 % of operating capacity (i.e. at 100 % of system capacity a 5 A CT should
output 3 A).
If the current transformers are sized so that the percentage of the output is
lower, the loss of resolution may cause inaccuracies in the monitoring and
control functions and affect the functionality of the control.
2 50 to 650000 V Some applications may require the use of potential transformers to facilitate
measuring the voltages to be monitored. The rating of the primary side of the
[400 V]
potential transformer must be entered into this parameter.
Notes
If the application does not require potential transformers (i.e. the measured
voltage is 480 V or less), then the measured voltage will be entered into this
parameter.
