Installing the Rotating Switch Operator
If the travel limits have not been set, the CLOSED 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 operator from the switch (see Step 2 on page 19), and manually close he
switch. 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 that all of the following are true:
• The REMOTE/LOCAL switch is in
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: 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 shaft 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
screen.
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.
STEP 8.
Press the ALIGN button on the faceplate to take the switch operator out of
Align
mode.
STEP 9.
Press the SET LIMITS button on the faceplate to enter the
Set Limits
mode. The
LCD screen will show **Set Limits Mode** on the top line and “Press the CLOSE
or OPEN button to jog switch position” on the bottom line.
STEP 10.
Press the CLOSE button and the switch will be closed under tension. The
CLOSE LED will change from blinking to lit, indicating the close limit is set.
STEP 11.
Press the SET LIMITS button to take the operator out of the
Set Limits
mode.
STEP 12.
Press the ALIGN button to enter the
Align
mode.
STEP 13.
Press the OPEN button many times until the switch is in the fully
Open
position.
STEP 14.
Press the ALIGN button to take the operator out of the
Align
mode.
STEP 15.
Press the SET LIMITS button to enter the
Set Limits
mode.
STEP 16.
Press the OPEN button and the switch will be opened under tension. The OPEN
LED will change from blinking to lit, indicating the open limit is set.
