Installing the Reciprocating Switch Operator
CAUTION
The switch operator is capable of generating tremendous force. It is essential
to install the switch operator rod and linkages with couplings that will not slip
under very high force conditions. The connections should be made only with the
manufacturer’s supplied fittings. The 3/8-inch grade 5 link-clamping bolt should be
torqued to a setting of 32 foot-pounds with a properly calibrated torque wrench.
Under-tightening the fitting may lead to slippage and improper switch operation.
Over-tightening the fittings may cause their failure and a subsequent inability to
operate the switch.
The switch operator is capable of stand-alone automatic switch operation, such
as voltage loss-line sectionalizing, as well as remote operation via SCADA. Before
coupling or decoupling the switch from the switch operator, or attempting any
manual operation with the mechanical operating handle, always:
• Remove the manual operating handle, supplied with the switch operator, from its
storage location on the faceplate.
• Toggle the REMOTE/LOCAL switch to the
Local state.
• Make sure the ENABLE/DISABLED LED indicates
Disabled state.
• Open the dc circuit breaker behind the faceplate.
Do not attempt to operate the switch attached to a newly installed switch operator
until the setup software has been properly configured for the installation or before
the limits of operator travel have been set.
Putting the Switch Into
Local/Non-automatic
Service
Remove any temporarily installed bypass, and release the switch for local, nonautomatic
operation from the faceplate.
CAUTION
Be sure to leave the switch operator in
Local state (not Remote state) and
AUTOMATIC OPERATION in
Disabled state (not Enabled state) until the software
in the switch operator is set up for this installation.
This completes the reciprocating switch operator hardware installation.
See Instruction Sheet 1045M-530, “S&C 6801M Automatic Switch Operators:
Setup”
for
information about configuring the switch operator.
