Electronic Control
The electronic circuits for programming the operating
sequence, minimum-trip levels, time–current characteris-
tics, and other parameters are located in a separate pad-
lockable cabinet that can be mounted at any convenient
accessible location, near or remote from the recloser.
No external power source is required to operate the elec-
tronics. Power is obtained from the line by means of a
1000:1 bushing current transformer mounted in the head
of the recloser. A minimum of 3 A of primary current flow
is sufficient to power the sensing circuits and charge the
trip capacitors which actuate the low-energy actuator. A 9 V,
1.4 Ah lithium battery is provided to supply energy to
actuate the closing contactor. And, in the event that cur-
rent drops below 3 A, the battery will ensure proper con-
trol operation.
Electronic control circuitry is centralized on a single print-
ed circuit board which is easily replaceable. DIP switch
programmable control parameters, along with easily
replaceable TCC cards, increase application flexibility.
Refer to the
Control Programming and Operation
section
of this manual for further information.
The VXE control can be equipped with an optional SCADA
input/output board to provide remote operation and status
functions for SCADA applications. Refer to the
Accessories
section of this manual for additional information.
Recloser Data Plates
Check the recloser data plates (Figure 3), which are
located on the sleet hood, to make sure the closing coil
voltage, the voltage, and the current ratings are compat-
ible with the system on which the recloser is to be
installed.

WARNING:
Hazardous voltage. Closing coil volt-
age and current ratings must be compatible with
the system application. Refer to the data plates, located
on the sleethood of the recloser, for specific rating infor-
mation. Failure to comply can result in death, severe
personal injury, and equipment damage.
