Installing the Reciprocating Switch Operator
Adding Ac Power
Follow these steps to add ac power:
STEP 1.
Energize the ac power line into the switch operator enclosure.
STEP 2.
Insert the ac line fuse and turn on the dc breaker.
STEP 3.
Check the AC ON, BAT ON, and CHG ON LEDs on the Battery Charger/
Control I/O board.
When the 10-A ac line fuse is inserted, the red AC ON LED
should illuminate. When the dc breaker is turned on, the BAT ON and CHG ON
LEDs should illuminate. The Battery Charger/Control I/O board is on the left
side of the enclosure.
If any of these LEDs does not illuminate, see Instruction Sheet 1045M-550,
“S&C 6801M Automatic Switch Operator:
Troubleshooting
.”
DANGER
The following procedure requires that the switch be fully bypassed or de-energized.
Operating an energized switch that is not bypassed will result in serious personal
injury or death, as well as damage to the switch.
If the travel limits have not been set, the CLOSE LED will blink. Follow these steps to
set the travel limits:
STEP 1.
The switch should be in the
Closed
position. If it is not closed, decouple the
switch and manually close it. Visually confirm all blades are fully seated on the
close stops and all contacts are fully engaged. Then, recouple the switch
operator and switch.
NOTICE
Several conditions can prevent the actuator shaft from being operated from the
faceplate. Be sure all of the following are true:
• The REMOTE/LOCAL switch is in he
Local state.
• The manual handle is stowed in its mounting bracket on the faceplate. This is a
safety feature of the switch operator.
• The BATTERY LOW LED display is off. Note that whenever the switch operator
is running on ac power with the dc circuit breaker open/tripped, the BATTERY
LOW LED will be on. This condition must be cleared before any movement of the
actuator arm is possible. To clear the condition, reset the circuit breaker, make
sure the batteries are connected, and execute a battery test cycle by pressing
the TEST BATTERY switch on the faceplate. When the LED turns off, operation
is enabled.
If all of these are true and the actuator still will not move in low-speed
Align
mode, error diagnostic conditions may be present. Use a computer to examine
other possible conditions on the
Diagnostics>Alarms
,
Diagnostics>Warnings
, and
Diagnostics>Errors
screens. Internal errors can be cleared from the appropriate
Diagnostics
screens.
STEP 2.
Press the ALIGN button on the faceplate. The NOT READY LED will blink slowly
to indicate
Align
mode. The LCD screen will show **Align Mode** on the top
line, and “Press the CLOSE or OPEN button to jog the switch position” on the
bottom line. This enables slow operation to jog the operator each time an OPEN
or CLOSE button is pressed.
STEP 3.
Press the CLOSE or OPEN button to jog the operator slot so it aligns with the
switch decoupling slot.
STEP 4.
Remove the decoupling pin.
STEP 5.
Push the coupling wedge forward and push the handle bracket up to lock the
wedge in the slots. If it is difficult to seat the coupling wedge, it may be necessary
to use the manual handle to align the two slots.
STEP 6.
Insert the decoupling pin to lock the wedge.
STEP 7.
If the manual handle was used, return it to the faceplate.
