DESCRIPTION

The Turner Hydraulic Actuated Motor Operator (HAMO) model HS-3 is a constant speed, constant torque, reciprocating operator for use with airbreak disconnect switches. The modular unit can be utilized to operate a switch from remote locations and for automation relay switching schemes.

OPERATION

The HS-3 power unit consists of a motor driven hydraulic pump, with solenoid-actuated valves and a hydraulic RAM. When activated, the solenoid valves are energized allowing fluid to be pumped into the RAM thus rotating the output shaft in the desired direction. (See Figure 1.)

IMPORTANT:
Regardless if unit is installed on a new or existing switch, the disconnect switch should be completely and properly adjusted and operating satisfactorily prior to motor operator installation. If an existing switch, proper maintenance should be performed. Installation of the operator should be done with the switch and the operator in the closed position.

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 HS-3 operator securely to the switch structure or pole with thru bolts and lag screws. (See dwg. 8935 or appropriate drawing.)

2.0 Place the HS-3 operating arm in the down position. Confirm that the switch vertical operating pipe is extended or in the down position. This is normally when the switch is open.

3.0 Cut the vertical operating pipe so that 5 inches will protrude through the drive clevis on the operating arm. Insert pipe into drive clevis and secure. Do not pierce.

3.1 Insert the manual operating handle in the handle socket. (See Figure 2.) Decouple the operating arm from the output shaft by:
a.) Remove lock from coupling pins. (See Figure 3.)
b.) Rotate pins downward approximately 45' and withdraw. (Figure 4 & Figure 5) You should now be able to rotate manual handle up and down freely. (Figure 6)
c.) Note that if the motor operator is not synchronized with the operating arm, the coupling pins cannot be inserted through the output shaft into the operating arm. For example, the motor operator is open and the switch has been manually closed, the unit cannot be recoupled.
d.) Reverse step 3. 1 a, b, & c to recouple motor operator to switch.

3.2 With operator decoupled, rotate manual handle upward and close the switch. If the switch does not close, adjust the slotted drive arm to provide adequate vertical travel to properly close the switch.

3.3 Pierce pipe coupling screws (2) on vertical operating pipe.
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.

3.4 Complete battery cabinet AC & DC wiring. See wiring diagram for proper motor operator fuse block wiring. Confirm polarity.
The HS-3 is shipped with the reservoir filled. Before any energizing of the unit, remove the large reservoir plug from the reservoir and replace with the vented breather cap.

3.5 It is imperative that the installers fully understand the role and sequence of operation of the various devices in the HS-3. Please carefully review the following opening and closing description prior to energizing the equipment. Please note that units are shipped in a clockwise to open set up as standard view from outside the cabinet. (Unless specified otherwise in the order.) A tag on the actuator is marked accordingly. Confirm that the opening direction of the operator and the opening direction of the switch are identical. If they are not, reverse the unit per instruction at 20.

4.0 OPEN & CLOSE CYCLE DESCRIPTION

5.0 Check hydraulic fluid level in motor/pump reservoir. The filler hole is located on the top side of the reservoir. If required, insert the funnel tube (included) into the filler hole and fill with fluid (included) 3/4" - 1 " from the reservoir top with actuator retracted.

NOTE: DO NOT INSERT FUSES UNTIL OIL RESERVOIR LEVEL HAS BEEN CHECKED AND THE LARGE PLUG REMOVED AND REPLACED WITH THE VENTED BREATHER CAP.

6.0 Insert fuses (included) per the following fuse schedule.

Terminal Block Position	24 Volt	48 Volt
F1	FRN30	Consult Factory
F2	NON6
F3	NON6
F4	MDL-10 (Optional battery charger, 24VDC only)

Decouple operator handle (handle down). Manually open switch and leave handle disengaged.
Note at this time that:
Limit switch 1 controls cw rotation.
Limit switch 2 controls ccw rotation.
Limit switch 3 operates the red/green indicator lights.
See Figure 1 for location.

7.0 Depress local/remote selector switch and operate toggle switch to left (open). Recall that the switch is in the open position and that the operator was shipped in half open position or midpoint.

8.0 The output shaft and stop will rotate and stop just prior to coming into contact with one of the adjustable over-travel stops. The unit must stop approximately 1/8" before the stop comes into contact with the over-travel stop. The over-travel stop should be adjusted to limit the travel of the stop. The limit switch, which controls the opening rotation, may need adjustment (See 6.0 above to determine controlling switch.)

9.0 Insert the coupling pins in the output drive assembly. In the event the inner drive flange holes do not line up with the outer drive flange holes preventing insertion of coupling pins, adjust Cam for limit switch controlling CCW, open rotation so that coupling pins can be inserted.

9.1 Decouple and manually close the switch.

10.0 Depress local/remote or switch and operate the toggle to right (close). Repeat same procedure for over-travel stop adjustment as discussed in step 8.0. The limit switch, which controls the closing rotation, may need adjustment in order for coupling pins to be inserted. (See 6.0 above to determine the controlling switch.)

10.1 Refer to 8.0 for over-travel stop adjustment, confirm.

11.0 Couple switch to hydraulic operator by inserting coupling pins.

12.0 Open the switch with the operator.

12.1 As the switch opens, confirm that the stops are properly adjusted. IMPORTANT - Do not overdrive the operator. Confirm switch opening clearance is adequate.

13.0 Close the switch with the operator.

13.1 As the switch closes, confirm that the stops are properly adjusted. DO NOT OVERDRIVE. Confirm switch fully closed.

14.0 After all adjustments are completed, pierce all set screws and tighten both Cam set screws. Tighten lock down stops and install the stop shroud at the top of the cabinet.

15.0 Connect remote control wiring: (see wiring diagram)
Three wires from customers equipment are required:

Labeled Common -- + found on TB 1-6
Labeled Open -- found on TB 1-7
Labeled Close -- found on TB 1-8

Note that the customers control input must be disengaged prior to end of HS-3 operation. If it is not, unit will continue to attempt to operate. The HS-3 electrically seals in, requiring only a short duration (< 1 sec.) Control input.

16.0 Rotation limits
All HS-3 units are factory adjusted for 901 rotation, unless specified otherwise. If the application requires greater than 901 rotation (up to 1201) make the following changes:

a) Change the position of the over-travel and lockdown stops located on the output power shaft.
b) Change the position of Cams for LSI, LS2, and LS3 to reflect the increased travel. See Section 6.0 of instruction book to determine which Cam controls the particular function of the operator.

17.0 Reversing the unit
All HS-3 units are factory wired for CW closing unless specified otherwise. If it is necessary to reverse the unit for CCW closing, make the following connection changes:

a) Interchange green and red wires on LS1 and LS2.
b) Interchange blue and orange wires on LS1 and LS2
c) Interchange green and red wires on LS3.
d) Interchange solenoid "A" and "B" wires on TB 1-9 and 1-10.
e) Mark up appropriate wiring diagrams to reflect actual installation.

18.0 Consult attached trouble shooting guide in the event of installation problems.
