Electric Motor Op erator and Local Electric Close
Local Electric Close
A charging status indication (contact accessible at ter
minal point < L T 4>) provides the capability to remotely
monitor the stored energy mechanism. The contact is "on"
if the springs are fully charged. The contact will be alter
nately "on" for 300 milliseconds and "off" for 300 millisec
onds as the springs are charging or until 20 seconds have
elapsed, approximately twice the time required to charge
the springs. If the springs are not charged after 20 seconds,
the contact alternates between 1 second "on" and 1
second "off, " indicating thatthere is a problem. SB breakers
with an electric operator may be charged manually if the
electric operator is disabled for any reason .
The local electric close allows the user to electrically inter
lock a local closing operation. It is available for breakers
with either the electric operator or remote closing solenoid.
The local electric close is commonly used i n conjunction
with a manual close-blocking device (See Close Blocking
Device, page 58).
