Checking the Switch Operator and Alduti‑Rupter® Switch Positions Before Operation

Do not assume the switch operator position necessarily indicates the Open or Closed position of the Alduti- Rupter Switch. Upon completion of an opening or closing operation (electrical or manual), make sure the following conditions exist:

• The switch operator position indicator, Figure 5 on page 13, signals “OPEN” or “CLOSED” to indicate that the switch operator has moved through a complete operation. Also note the POSITION INDICATING lamps, Figure 2 on page 9, if furnished.
• The operating lever, at the rear of the switch operator, see Figure 1 on page 8, is in the Up position for an Alduti-Rupter Switch Closed position. Conversely, the operating lever is in the Down position for an Alduti-Rupter Switch Open position.
• The blades on all three poles of the Alduti-Rupter Switch are fully open or fully closed (by visual verification). Then, tag and padlock the switch operator in accordance with standard system operating procedures. In all cases, make sure the switch operator is padlocked before “walking away.”

Elektriline töö
Complete the following steps to open or close the interrupter switch electronically:

• Step 1. Unlock and lift the external pushbutton protective cover.●
• Step 2. Press the appropriate pushbutton.■ See Figure 2 on page 9.

Alternatively, the switch operator may be activated by operating associated, remotely located control switches. (No instructions are included for activating the switch operator by means of remotely located control switches because control schemes vary with different installations. With any given installation, however, it may be possible and desirable to effect such operation. Instructions presented in this document cover operation at the switch operator only.)

● For switch operators with an optional remote-control blocking switch (suffix “-Y”), opening the pushbutton protective cover prevents remote operation of the switch operator.
■ OPEN/CLOSE pushbuttons are not included on switch operators specified with catalog number suffix “-J.”

Käsitsi juhtkäepideme kasutamine
The manual operating handle is used during switch operator adjustment. Become familiar with the operation of the manual operating handle, as described on the switch operator nameplate on the right-hand side of the enclosure.

HOIATUS
DO NOT manually open or close the switch operator while the Alduti-Rupter Switch is energized. Operating the switch under reduced operating speed can cause excessive arcing, resulting in shortened interrupter life, damage to the interrupters, or personal injury. If switch operator control voltage is not available and emergency manual opening is absolutely necessary, crank the manual operating handle rapidly throughout its full travel. Do not stop or hesitate partway. Never close the switch manually.

• Step 1. Pull the latch knob on the hub of the manual operating handle and pivot the handle forward slightly from its Storage position.
• Step 2. Release the latch knob while continuing to pivot the handle forward to lock it into the cranking position. See Figure 3. (As the handle is pivoted forward, the motor brake is mechanically released, both leads of the control source are automatically disconnected, and—except for 12-Vdc models—both the “opening” and “closing” motor contactors are mechanically blocked in the Open position.)
• Step 3. Crank the handle to the Open position. If desired, during manual operation, the switch operator may also be disconnected from the control source by removing the motor-circuit two-pole pull-out fuse holder, located on the right-hand inside wall of the enclosure.
• Step 4. To return the manual operating handle to its Storage position: Pull the latch knob and pivot the handle approximately 90 degrees. The handle will then be disengaged from the switch operator and may be rotated freely in either direction to its Storage position. Complete the handle storage by pivoting the operating handle backward approximately
  90 degrees until it latches in the Storage position. Always padlock the handle in its Storage position.
  Note: The manual operating handle may be disengaged from the switch operator mechanism at any position of the handle.

The selector handle will be used during switch operator adjustment. The integral external selector handle, for operation of the built-in internal decoupling mechanism, is located on the right-hand side of the switch operator enclosure. Become familiar with the operation of the selector handle, as described on the switch operator nameplate on the right-hand side of the enclosure.

Lüliti operaatori lülitist lahtiühendamiseks tehke järgmist.

• Step 1. Swing the selector handle upright and slowly rotate it clockwise 50 degrees to the Decoupled position. See Figure 4. This decouples the switch operator mechanism from the switch operator output shaft.
• Step 2. Lower the selector handle to engage the locking tab. When decoupled, the switch operator may be operated either manually or electrically without operating the Alduti- Rupter Switch. When the selector handle is in the Decoupled position, the output shaft is prevented from moving by a mechanical locking device located within the switch operator enclosure. During the intermediate segment of the selector handle travel, which includes the position at which actual disengagement (or engagement) of the internal decoupling mechanism occurs, the motor circuit source leads are momentarily disconnected and (except for 12-Vdc models) both the “opening” and “closing” motor contactors are mechanically blocked in the Open position. Visual inspection, through the observation window will verify whether the internal decoupling mechanism is in the Coupled or Decoupled position.
• Step 3. Padlock the selector handle in either position.

Lüliti operaatori ühendamiseks lülitiga:

• Step 1. Manually operate the switch operator to bring it to the same Open or Closed position as the Alduti- Rupter Switch. The SWITCH OPERATOR POSITION indicator, seen through the observation window will show when the approximate Open or Closed position has been attained. See Figure 5.
• Step 2. Turn the manual operating handle slowly until the position-indexing drums are numerically aligned to move the switch operator to the exact position for coupling.
• Step 3. Swing the selector handle upright and rotate it counterclockwise to the Coupled position.
• Step 4. Lower the handle to engage the locking tab. The selector handle is now in the Coupled position.
• Step 5. Padlock the selector handle in either position.

Final Checks Before Walking Away
To ensure the switch operator is ready for normal power operation of the Alduti- Rupter Switch by remote automatic or supervisory control, make sure the following conditions exist:

• The selector handle is in the Coupled position.
• The manual operating handle is in its Storage position.
• The two-pole pull-out fuse holders for the motor circuit and space-heater circuit are inserted.
• The pushbutton protective cover is closed.
• The switch operator is tagged and padlocked in accordance with standard system operating procedures.

Ülevaatus

To ensure continued proper performance of the Type AS-10 Switch Operator, it should be inspected every 5 years. De-energize the associated Alduti-Rupter Switch and perform the following switch operator inspection procedures:

• Step 1. Check for evidence of water ingress, damage, and excessive corrosion or wear.
• Step 2. Check ease of operation during slow, manual cranking using the switch operator manual operating handle.
• Step 3. Check electrical operation, coupled and decoupled.
• Step 4. Check for loose wiring inside the enclosure and proper functioning of the POSITION INDICATING lamps, operatsioonide loendur, mugavus lampjne.
• Step 5. Check the operation of brake and readjust if necessary.

The procedure for doing this is as follows. All detail views can be found in Figure 6.

• (a) Place the selector handle in the Decoupled position.
• (b) Remove the two-pole pull-out fuse holders for the motor circuit and space-heater circuit.
• (c) Disconnect the linkage rod by removing the ¼–20×1¼-inch hex-head screw, lockwasher, flat washer, and spacer-bushing from the end of the brake lever, as shown in Detail A. Be careful not to lose these parts.
• (d) Raise the brake lever and measure the vertical free play, as shown in Detail B. This dimension should be 5/8 inch (16 mm) to ¾ inch (19 mm). Should the measurement be outside this range, brake-wear compensation is required; proceed to Step 5 (e). If the measurement is within this range, reattach the linkage rod and tighten the ¼–20×1¼-inch hex-head screwsecurely; proceed to Step 5 (j).
• (e) Remove the four 5⁄16–18×1¼-inch screws used to attach the motor, withdraw the motor, and carefully rest its shaft on the floor of the enclosure. Be careful not to lose the square key or tubular spacer (if furnished), which may remain on the motor shaft.
  Note: 115-Volt ac and 230-Volt ac motors utilize a ¼-inch–20 socket-head set screw on the side of the brake disc hub, as shown in Detail C. Loosen this set screw approximately one-half turn, using a 1/8-inch Allen wrench, before removing the motor.
• (f) Using a 3⁄32-inch Allen wrench, loosen the pad assembly socket-head set screw on theside of the caliper assembly approximately one-half turn. See Detail A.
• (g) Then, using a 5⁄16-inch Allen wrench, rotate the pad assembly clockwise until the free play at the end of the brake lever is 5/8 inch (16 mm) to ¾ inch (19 mm) as shown in Detail B. Now tighten the 3⁄32-inch pad assembly socket-head set screw.
• (h) Insert the spacer-bushing through the angle bracket and brake lever, and reattach the linkage rod using the ¼–20 × ¼-inch hex-head screw, lockwasher, and flat washer. Tighten the screw securely.
• (i) Insert the square key in the keyway, as shown in Detail A. Slip the tubular spacer (if furnished) over the motor shaft and reinstall the motor. Position the motor such that the two weep holes on the side of the housing face downward. Replace the four 5⁄16–18×1¼-inch screws used to attach the motor and tighten them securely.
  On 115-Volt ac and 230-Volt ac motors: Retighten the ¼-inch–20 sockethead set screw on the side of the brake disc hub.
• (j) Pull the latch knob on the hub of the manual operating handle and slowly pivot the handle forward from its storage position toward its cranking position until the brake disc can be rotated by hand. Be careful not to get grease on the brake disc.
  Now measure the distance that the end of the brake lever travels from the point of initial brake release to the bottom of its stroke (which occurs when the handle locks into the cranking position). This dimension should be 1/8 inch (3 mm) to ¼ inch (6 mm). See Detail D. Should the measurement be outside this range, referto the nearest S&C Sales Office.

Since the Type AS-10 Switch Operator may be conveniently decoupled from the Alduti-Rupter Switch, elective exercising of the operator may be performed at any time without requiring an outage or switching to an alternate source.
