SPEAR™ Single-Phase Recloser System
INSTALLATION AND OPERATION INSTRUCTIONS MN280048EN June 2016
When the CONTROL OK LED is flashing, the
following message appears on the LCD display upon
power-up:
Protection Off. Change protec. setting. Use ESC to
clear message.
As soon as the HMI goes into power save mode
(inactivity for 15 minutes) the message will no longer
display on the LCD, but the CONTROL OK LED will
continue to flash to indicate protection is disabled.
The control must be programmed with the SPEAR Single-
Phase Recloser Control ProView NXG interface software.
Refer to Service Information MN280012EN SPEAR Single-
Phase Recloser Control Programming Guide for additional
information.
Control / recloser compatibility
The SPEAR Single-Phase Recloser Control is compatible
with the SPEAR Single-Phase Recloser. It is not compatible
with three-phase electronically controlled reclosers, or other
single-phase reclosers such as Eaton’s Cooper Power series
VXE or NOVA
1
reclosers.
Duty cycle monitor
The Duty Cycle Monitor provides the following duty cycle
information:
Measures and records duty in non-volatile memory.
The recloser duty is measured and stored on the basis of
Current ^ 1.5 x Number of Operations (ANSI C37.61).
Readout is based on a percentage of total duty cycle.
Duty record can be adjusted or reset if recloser is
changed-out, serviced, etc.
Using Table 8, select the appropriate recloser interrupting
duty cycle factor and enter that value via the ProView NXG
interface software.

Mounting the control
Mount the SPEAR single-phase recloser control in a
convenient, accessible location. Mounting dimensions are
provided in Figure 18.
ote:N Unless otherwise specified, dimensions shown in
inches.
A hole and keyway in the control mounting bracket
accommodates a 0.50 in (12 mm) diameter bolt.
WARNING
This equipment is not intended to protect human
life. Follow all locally approved procedures and safety
practices when installing or operating this equipment.
Failure to comply can result in death, severe personal
injury, and equipment damage.

IMPORTANT
When opened, the inside of the front door has a ground
braid connected to the bottom right corner to the control
cabinet. To access behind the SPEAR single-phase recloser
control module, turn both front quarter-turn latches counter-
clockwise until the swing panel is released and it can be
swung into the open position.
Control cable
The control cable is fabricated with connectors which mate
with the male receptacle of the recloser on one end, and
the female receptacle of the control on the other end.
ote:N The control cable must be supported along its length
to prevent repeated movement due to wind or other
outside forces which can damage the cable.
SPEAR single-phase recloser control cable lengths are
available from 5 ft. (1.5 m) to 50 ft. (15.0 m).
IMPORTANT
All external inputs to the SPEAR single-phase recloser
control must be routed within 8 inches of their
corresponding ground. During a surge, a potential of
approximately 1.5 kV per foot can develop in the conductors.
Differences between conductor and ground path lengths
can add additional stress to the control components in the
event of a power surge.
