STEP 25. When the circuit-switcher is ready to be placed in
service, the motor and closing circuit fuses can—at
the user’s option—be replaced with the slugs
furnished. This practice is recommended for
increased reliability because low-voltage fuses can
be damaged by the repeated inrush current
experienced during normal opening operations and
can “sneak out,” leaving the circuit-switcher
inoperable.

Operation
Understanding Trip-Free Operation
The stored-energy mechanism has an instantaneous trip-free
capability. If the Series 2000 Circuit-Switcher is closed into
a fault sensed by the user-furnished relaying, the mechanism
will immediately trip. To accomplish trip-free operation, the
stored-energy mechanism uses two spring assemblies: one
for closing and one for opening. Both springs are charged by
the operator motor before the circuit-switcher can be closed.
Recharging time after a Trip operation is approximately 10
seconds for Model 2040 Circuit-Switchers rated 69 kV through
138 kV and 16 seconds for circuit-switchers rated 161 kV and
230 kV.
Electrical Operation
To Open the circuit-switcher, press the TRIP pushbutton or
send a remote trip signal to the switch operator. See Figure
16 on page 20.
The opening latch in the stored-energy mechanism will
release, discharging the opening spring. This action trips
the interrupters and forces the opening and closing pistons
in the mechanism downward, which can be seen in the DISCHARGED indicator window inside the operator. See Figure
26 on page 27. The switch-position indicator on the high-speed
base will move to the Open position. See Figure 25. Further,
if the position-indicating lamp option (catalog number suffix
“-M”) has been specified, the green lamp will light.
The motor-driven cam in the stored-energy mechanism will
immediately start rising, thereby charging both the opening
and closing springs; when the opening spr ing latches, the indicator will again be visible at the CHARGED indicator window.
To Close the circuit-switcher, press the CLOSE pushbutton or
send a remote close signal to the switch operator. See Figure
16 on page 20.
The motor-driven cam in the stored-energy mechanism will
immed iately star t retracting. The closing latch will release, discharging the closing spring. This action closes the interr upters.
The switch-position indicator on the hig h-speed base wil l move
the Closed position. See Figure 25. If the position-indicating
lamp option has been specified, the red lamp will light.
The circuit-switcher may also be electrically operated
via remotely located control switches. No instructions are
included for remote control because control schemes vary
with the installation and specific application of the switch.

Page 27
Manual Operation
To trip the interrupters, push the manual TRIP lever
counterclockwise as indicated by the TRIP lever label. See
Figure 16 on page 20. The opening latch in the stored-energy
mechanism will release, discharging the opening spring. This
action trips the interrupters and forces the openi ng and closing
pistons in the mechanism downward, as denoted by movement
of the indicator to the DISCHARGED indicator window. (See
Figure 26.) The switch-position indicator on the high-speed
base will move to the Open position. (See Figure 25 on page 26.)
If the position-indicating lamp option has been speci ed—and
operator control voltage is available—the green lamp will light.
If operator control voltage is available, the motor-driven
cam in the stored-energy mechanism will immediately start
rising, charging both the opening and closing springs. When
the opening spring latches, the indicator will again be visible
at the Charged window.
If operator control voltage is not available, the interrupters will open. The motor-driven cam in the stored-energy
mechanism will charge the opening and closing springs when
control power is restored to the operator.
Manual closing of the circuit-sw itcher cannot be performed.

Understanding the Gas-Pressure Indicator
and Safety Relief Device
Series 2000 Circuit-Switchers have sealed interrupters
containing gas under pressure. Loss of gas pressure may result
in improper interrupting action. Low gas pressure is signaled
by a red target in the GAS PRESSURE indicator at the upper
terminal end of the interrupter.
Figure 27 illustrates a GAS PRESSURE indicator with
acceptable gas pressure.
Figure 28 illustrates a GAS PRESSURE indicator with a red
target, signaling a loss in gas-pressure.
Understanding the Optional Remote GasDensity Monitor
The remote gas-density monitor provides local and remote
indication of the gas density in each interrupter in terms
of percent full. The system can be wired to provide remote
indication of the gas density of each interrupter via three
analog 0 to 1.0 mA dc outputs. The LCD screen provides
indication of gas density and alarms for each interrupter. The
remote gas-density monitor transmits updated measurements
approximately once per hour.
The remote gas-density monitor has three available
alarm contacts. The system provides both local and remote
indication of ala rms.
Level 1 Alarm indicates an interrupter is leaking. The
circuit-switcher can still be operated, but the leaking interrupter should be replaced promptly.
Level 2 Alarm indicates an interrupter has lost enough
SF6 gas it can no longer clear faults properly.
System Trouble Alarm indicates a problem with the
monitoring system. A system trouble alarm will activate
when the receiver fails to receive a signal for over 24 hours.
The system trouble alarm will also activate when there are
approximately three months or less of battery life remaining.
At first, a Low-Battery alarm will appear locally. After the
battery has completely discharged, an “Error” message will
appear in place of the percent-gas-density information, and
the system trouble alarm will signal remotely.
For complete instructions on installing, operating, and
troubleshooting the optional remote gas-density monitor, refer
to S&C Instr uction Sheet 716-530.
