Cooper Power Systems NOVA 15 - Form 5 Control Settings

Operation
Form 5 Control Settings
The Form 5 control must be programmed with an adjusted
voltage sensor ratio and a phase angle correction; refer to
Tables 8 and 9. These are entered in the Form 5, Voltage
Sensor Parameters screen (Figure 19).
The Form 5 control Recloser Interface (RIF) module must
be set to 12 V for the source side bushings. (The load side
bushings are not configured to work with the internal volt-
age sensing option and are set as described in the Form
5 Programming Guide.) Also, the Phantom Phase feature
can not be enabled on the Form 5 control when using the
voltage sensing option.
Refer to • ServiceInformationS280-79-10 for installation
and operation information of the Form 5 control.
Refer to • ServiceInformationS280-79-2 for more infor-
mation on programming the Form 5 control.

Note: For Form 4D controls, the phase shift is adjusted -0.6°
for each additional 3.05 m (10 ft.) of cable.
For Form 5 controls, the phase shift is adjusted -0.8° for
each additional 3.05 m (10 ft.) of cable.
For Form 6 controls, the phase shift is adjusted +0.8° for
each additional 3.05 m (10 ft.) of cable.
Note: This Service Information issue contains the correct
phase angle adjustment for concurrent cable and reclos-
er design. Note the manual issue date and correspond-
ing recloser serial numbers: design changes can impact
the phase angle adjustment.
*Maximum cable length is 15.25 m (50 ft.).
