The Type AS-10 Switch Operator is a high-speed operator, with an operating time of 1.2 seconds maximum. It is expressly designed for power operation of outdoor distribution Alduti-Rupter Switches and outdoor distribution Alduti-Rupter Switches with Power Fuses, having reciprocating type operating mechanisms.
The high operating speed of the Type AS-10 Switch Operator provides sufficient moving-contact velocity in the Alduti-Rupter Switch interrupters to ensure full interrupting capability and long operating life. The operator’s high operating speed also provides adequate closing velocity for 25/34.5-kV and 34.5-kV three-pole side-break integer style and three-pole vertical-break integer style switches such that the side-break integer style switches have a one-time duty-cycle fault-closing rating of 15,000 amperes RMS, asymmetrical, and the vertical-break integer style have one-time duty-cycle fault-closing ratings of 20,000 or 30,000 amperes rms asymmetrical for switches rated 600 amperes eða 1200 amperes, respectively.
For power operation of outdoor distribution Alduti-Rupter Switches and outdoor distribution Alduti-Rupter Switches with Power Fuses, having rotating type operating mechanisms, the Type AS-1A Switch Operator is offered. See S&C Instruction Sheet 769-500.

These illustrations are not applicable to 12-Vdc models . 12-Vdc models use different component parts and a different internal layout . The differences include a constant-burden battery charger mounted on a swingout panel, as well as the use of a separate two-pole control-source disconnect switch in series with control-source fuses (located on the inside rear wall) instead of the motor-circuit two-pole pull-out fuseholder . The 12-Vdc models include a separate compartment beneath the enclosure to house the 12-Vdc battery .

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).
Þá, 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.”
Rafmagnsrekstur
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 .”

SKREF 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.)
SKREF 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.
SKREF 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

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.
Til að aftengja rofastjórann frá rofanum:
SKREF 1.
Snúðu veltibúnaðinum upp og snúðu honum hægt réttsælis um 50 gráður í aftengda stöðu. Sjá mynd 4. Þetta aftengdir rofastýribúnaðinn frá úttaksás rofastýrisins.
SKREF 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.

Check operation of brake and readjust if necessary. The procedure for doing this is as follows. All detail views can be found in Figure 6 on page 16.
(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 ¼20×1¼-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 ¼20×1¼-inch hex-head screw securely; proceed to Step 5 (j).
(e) Remove the four 5/1618×1¼-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-inch20 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 the side 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 ¼20 × 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 5/1618×1¼-inch screws used to attach the motor and tighten them securely.
On 115-Volt ac and 230-Volt ac motors: Retighten the ¼-inch20 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, refer to 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.
