Exit; Edit Set Points (3 And 4 Wire Systems) - Eaton Cutler-Hammer IQ 300 Series Instructions For Installation, Operation And Maintenance

In PHASE mode the output will be in closed state when the three phase voltages
are in phase and the open state when the three phase voltages are out of phase.
When in Voltage mode the output will be closed when the voltage strays from the
100% nominal reading. The nominal readings will be 120,
240, 480 and 575. The programmable trip value will
determine when the output will be closed. If the rms
voltage drops below a percentage less than 100% the
relay will be closed. If the rms voltage goes above a
percentage that is above 100% the relay will be closed. In
both cases the relay will stay closed until open by a
message. For example if the nominal voltage is 480 V and
you want the unit to trip if the voltage drops below 420 V,
multiply 420 by 100 and divide it by 480 to find your
setting.
To view the status of the trip value scroll up or down on the view setpoints menu to
TRIP VALUE, see figure 4.24.
Note: the MODBUS and INCOM forms of communication do not read the output
values. Refer to 4.10.8 notes for information on entering proper nominal readings.
