Duty Cycle Monitor
The Duty Cycle Monitor provides the following duty cycle
information:
• Measures and records duty for each individual phase in
non-volatile memory.
• The recloser duty is measured and stored on the basis
of
Current1.5 x Number of Operations for Each Phase
(ANSI C37.61).
• Readout is based on a percentage of total duty cycle
for each phase.
• Duty record can be adjusted or reset if recloser is
changed-out, serviced, etc.
Using Table 2, select the appropriate recloser interrupting
duty cycle factor and enter that value via the ProView inter-
face software.
Control Cable
The control cable is fabricated with connectors which mate
with the female receptacle of the recloser on one end, and
the male receptacle of the control or junction box on the
other end.
Note:
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.
Limits on control cable lengths are determined by the
recloser type and the distance between the control and
recloser: See Table 3 for available Form 6 recloser control
Cable Lengths for Kyle reclosers.

WARNING:
Hazardous voltage. Recloser and
control must be solidly grounded. Follow all
approved procedures and safety practices when
grounding this equipment. Improper grounding can
result in contact with high voltage, which will cause
death or severe personal injury.
G115.1
IMPORTANT:
All external inputs to the Form 6 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.
