The Turner Electromechanical Motor Operator model SF-300 is a two speed, high output operator for use with airbreak disconnect switches. The modular unit can be utilized to operate a switch from remote locations and for automatic relay switching schemes.OPERATION
The SF-300 power unit consists of an electric motor driven gearbox. When activated, the electric motor immediately begins rotation to open or close the switch. During the closing cycle, at a field settable position, a high-speed kick will engage to ensure complete closing of the switch.The switch operating speed is determined by the reduction in the gearbox. It is possible to modify the operating speed by changing the input gear. Consult the factory.
IMPORTANT:
Regardless if unit is installed on a new or existing switch, the switch should be completely and properly adjusted and operating satisfactorily prior to motor operator installation. If an existing switch, proper maintenance should be performed.OPERATOR MECHANICAL INSTALLATION
NOTE: Use the aluminum support channel for lifting the motor operator.1.0 Locate the required mounting heights for the operator. This would normally be at a height where an operating person can easily access the manual handle. Align operator power shaft with switch vertical operating pipe, (VOP) with a level. Mount the SF-300 operator securely to the switch structure or pole with through bolts and lag screws.
2.0 Cut off the vertical operating pipe (VOP) 11" from the top of the operator power shaft. See operator outline drawing for detail.
3.0 The handle assembly is a two (2) piece unit consisting of a manual swing handle/locking assembly and a four (4) piercing screw coupling for the VOP. The unit is shipped assembled with the pipe coupling secured to the handle with hand-tightened piercing screws. To install the handle assembly:
3.1 Remove the pipe coupling from the handle assembly and slide it up on the VOP. Orient the pipe coupling screws toward the mounting structure. Hand snug screws to hold the coupling in place.
3.2 Place the handle assembly over the slotted power shaft.
3.3 Align VOP and handle assembly. Loosen the pipe coupling and slide it down the handle.
3.4 Raise the entire handle coupling assembly one inch (1") above the power shaft bearing. Align handle tang with power shaft locking keyway. Tighten and PIERCE the pipe coupling's four (4) piercing screws.
3.5 Insert the manual-operating swing handle in the cast handle socket. (NOTE: "J" slot in handle should engage a pin in the socket). Confirm that the handle socket tang locks into the power shaft coupling keyway.
3.6 Manually operate the switch and adjust the swing handle position to obtain equal handle travel on both sides of operator centerline. Securely tighten piercing set screws and mark position of coupling to handle assembly. Remember that the switch operates 90 degrees to open or close.
3.7 The "lock down stops" are used to lock the switch in the open or closed position when the motor operator is disengaged from the VOP. Remove the swing handle and adjust the "lock down stops" in the open and close positions. Snug nuts.
3.8 Pierce two (2) pipe coupling screws on vertical operating pipe, PIERCE manual handle set screws.
IMPORTANT:
Manual operation of the switch must be satisfactory prior to motorizing. Again check the switch to make sure all necessary adjustments for switch levers, reach rods, arcing horns, interrupters, etc. are correct. See appropriate switch installation instruction book for details.3.9 Wire AC & DC power to the motor operator cabinet. See side panel and back panel wiring diagram for proper AC and DC fuse block wiring. CONFIRM POLARITY.
3.10 Install fuses. Note that fuses should be sized as follows:
F1: 6A
F2 and F5 (if applicable): 4A
F3 & F4: 40A4.0 OPEN & CLOSE CYCLE DESCRIPTION
It is imperative that the installer fully understands the role and sequence of operation of the various devices in the SF-300. Please carefully review the following opening and closing description prior to energizing the equipment. Please note that units are shipped in a counter clockwise to close set up as standard. (Unless specified otherwise in the order). If required, reverse the unit per instructions in section 16.ADJUST OPEN POSITION
NOTE:
Limit switch cams are set at the factory for 90° opening. However, some minor adjustments will be required to set open and close positions for the switch.5.0 With the switch de-coupled from the motor operator, set the local/off/remote switch to the "local" position and push the open/close toggle switch to the left (open).
6.0 The output shaft will rotate and stop. The output shaft slot should be aligned with the slot in the manual handle. The limit switch cam which controls the opening rotation may need adjustment. If the operator travels too far (past the slot in the shaft) then the cam will need to be rotated towards the front of the cabinet so that the limit switch opens slightly earlier. If the operator does not travel far enough, then the cam must be rotated so that the limit switch opens slightly later in the operation. Cam 5 controls the open indication light (green). Adjust cam 5 similar to cam 1.
Note:
If unit is set for CCW opening operation, cam 2 will control open rotation and cam 4 will control open indication light.ADJUST CLOSE POSITION
7.0 Manually close the switch.
8.0 Operate the open/close toggle switch to the right (close). The limit switch cam (cam 2) controlling the stop rotation may need adjustment. Repeat the same procedure for adjustment as outlined above in step 6. Cam 4 controls the closed indication light (red). Adjust cam 4 similar to cam 2. Note: If unit is set for CCW opening operation, cam 1 will control close rotation and cam 5 will control closed indication light.
9.0 Couple the switch to the motor operator (handle up and engaged in both switch and power shaft slots) and lock in position with a padlock through the locking hole.
10.0 Open the switch with the motor operator.
11.0 Once the switch is open, confirm that the switch is fully open and the open travel is properly adjusted. IMPORTANT - DO NOT OVERDRIVE THE OPERATOR.
12.0 Close the switch with the motor operator.
13.0 With the switch closed, confirm that switch is fully closed (blade latch is engaged). IMPORTANT - DO NOT OVERDRIVE THE OPERATOR.
14.0 Note the two-speed slow/fast close action. The switch blade should move normally through the first half of the close cycle. At approximately the one-half closed position, the high-speed kick should activate and quickly close the switch. Cam three will determine where the fast close cycle begins.
15.0 Connect remote control wiring at this time. Three wires from customer equipment are required:
Common + : TB1-1
Open: TB1-2
Close: TB1-3NOTE:
The contacts need only be closed a short duration (<1 sec) to ensure that the SF300 circuit will seal in and complete the open or close cycle.16.0 Reversing the unit
All SF300 units are factory wired for counter clockwise (CCW) closing unless otherwise noted. If it is necessary to reverse the unit for CW closing, make the following wiring changes:
16.1 Disconnect power to the motor operator by pulling the fuses and/or opening the knife switches (if equipped).
16.2 Reverse the red (RD) and black (BK) motor leads on the motor.
16.3 Interchange the orange (OR) and blue (BL) wires on limit switches 1 and 2. Interchange the red (RD) and green (GN) wires on limit switches 1 and 2.
16.4 Interchange the yellow (YL) and violet (VI) wires on limit switch 3.
16.5 Interchange the gray (GY) and black (BK) wires on limit switches 4 and 5.
16.6 Perform steps 5 through 15 above for adjustment of the limit switch cams and motor operator set points.
IMPORTANT:
The SF300 motor operator is geared specifically for a particular size of switch. See warning label on gearbox to determine the switch KV the operator is geared for. This insures that the operator is geared for the correct speed and torque requirements for each switch; no speed adjustment is necessary. Larger switches do not require as much closing speed, but do require more torque. Smaller switches require less torque, but greater speed to properly close and latch.The gearbox gear ratio can be changed with the following procedure and the correct gear should the operator be required to operate any switch other than that indicated on the warning label. Contact the factory for the proper gear should a gear ratio change be required.
17.0 To change gear ratio:
Contact factory for the correct gear if the motor operator is to be used on any switch other than that indicated on the warning label.
17.1 Open knife switches (if equipped) or pull fuses and disconnect power to the motor operator.
17.2 Remove the two power leads to the bottom of the motor. Remove the four bolts holding the motor mounting assembly to the bottom of the gearbox. Remove motor assembly.
17.3 Loosen the two allen screws from the gear on the motor shaft. Slide gear off motor shaft. See figure 1.
17.4 Install new gear on motor shaft and set with allen screws. Reverse procedure to install motor assembly.
17.5 Apply new warning label indicating correct switch KV over existing label.
NOTE:
Consult factory if changing from a 115kV or larger switch to a 69kV or smaller switch, or vice versa.18.0 Mechanical Brake
On units equipped with a mechanical brake, the brake must be disengaged via the manual brake release (MBR) switch, located on the operator panel, before the hand wheel can be used to manually move the gearbox. The brake is normally engaged. The brake disengages when power is applied to the brake coil either during normal operation or by the manual brake release switch, located on the operator panel. The switch must be held to keep the brake disengaged; the brake will re-engage upon release of the switch.
19.0 General Notes
19.1 The contactors are wired through each other's auxiliaries making it impossible to accidentally engage the open, close or fast close contactors at the same time.
19.2 The dynamic brake contactor will engage at the end of each open and close cycle and remain engaged for a few seconds. You may hear the contactor coil releasing.
19.3 Do not engage the high-speed close sooner than necessary as the blade could oscillate and not engage the jaw properly.
19.4 All the gears are cadmium plated for corrosion resistance. The gearbox is grease packed and should never need additional lubrication. The bearings on the output shaft are tapered roller bearings with grease seals for protection. All other bearings are permanently sealed ball bearings.
19.5 The electric motor is a permanent magnet motor with low temperature, permanently sealed bearings that never need additional lubrication.
