PK 8814 2 880 PRINTED IN USA a Honeywell Division Installation and adjusting instructions LZ metal-enclosed switches Description Description Sensing & Control To order replacement levers, order the same part number as that which is metal stamped on either the lever or lever hub. For other variations of levers, refer to Heavy Duty LS in Catalog 40. MOUNTING LZ may be mounted without unplugging the body from the base receptacle. Use two M5 or #10 screws that are at least 32mm (1.25 in.) long. A third mounting screw may be used by removing the knockout in the lower right corner. Refer to Figure 1. WIRING Up to 3mm or AWG12 wire may be used for wiring to the self-lifting pressure plate-type screw terminals. Maximum width of spade connectors or diameter of ring connectors is 8mm (.312 in.). A ground terminal, which is colored green for easy identification, also has self-lifting pressure plate-type construction (refer to Figure 1.). After wiring, screws in the ing. Also plug ensure proper securely tighten the captive plug-in unit for effective sealconduit opening with sealant to sealing. ADJUSTMENT INSTRUCTIONS Actuator Head All LZ actuator heads can be positioned in any of four directions. Loosen the four captive head screws, place the head in the desired position, and securely tighten the screws. Refer to Figure 2. Top Roller Plunger Position the top roller plunger in the desired plane by locating the head as outlined under Actuator Head. POSITIONING LEVER OF ROTARY TYPE The lever on rotary switches is adjustable to any angular position through 360°. Levers are reversible, they can also be shifted axially through approximately 3,2mm (.125 in.) on the shaft. To adjust, or to assemble to switch, loosen the screw with a 9/64 hexagon key wrench, move the lever to the desired position, and securely tighten the screw. The lever should be tightened until the "teller tab" can no longer be moved by hand. Hex key wrenches are provided in adjusting tool set LSZ4005. PK 88142 PK 88142 SIDE ROTARY TYPE CHANGING ACTUATION DIRECTION ON ROTARY TYPE Rotary switches may be adjusted to operate clockwise, counterclockwise, or both. Instructions are cast into the head (Figure 4). Follow these steps: 1. Loosen the four captive head screws and remove head from switch housing. 2. Switches are assembled with the plunger set for both way operation. (See drawing Figure 4.) Both way actuation: plunger point in twelve o'clock position (towards the actuator). To change mode of operation pull the spring loaded plunger outward with pliers to the stop. With plunger, pulled turn the point in the direction of operation required. Clockwise actuation only: turn clockwise to three o'clock position. Counterclockwise actuation only: turn counterclockwise to nine o'clock position. 3. Release plunger, it will snap into the head into a locked position. 4 . Replace operating head on switch housing and securely tighten screws. 5 . Check for desired operation by actuating switch and listening for "click". PK 88142 SIDE LEVER BRACKET TYPE POSITIONING THE SIDE LEVER BRACKET REVERSING THE ROLLER LEVER ARM The side lever bracket can be placed in any of four positions. When combined with the four possible head positions, this makes for 16 possible positions for this type. Remove the lever with a 5/32 inch hexagon key wrench. Loosen three captive bracket screws, place the bracket in the desired position, and securely tighten the screws (refer to Figure 6). Roller arms may be reversed to face the roller to the inside or outside of the arm (refer to Figure 7). It is recommended that the lever of side lever bracket forms be adjusted within the parameters shown in Figure 7. Use a 5/32 hexagon key wrench. HEX HEAD SCREWS If you prefer to loosen and tighten the lever with a pliers or a screwdriver, a packet of 50 hex head screws, with screwdriver slot, is available separately (catalog listing 15PA164-LS) to replace the allen head screw furnished with the lever. Adjusting tool set LSZ4005 consists of one special 3/32 inch open wrench and necessary hexagon key wrenches to adjust all types of levers. WOBBLE STICK ACTUATOR TYPE REPLACING THE WOBBLE STICK To remove a wobble stick, firmly grasp the wobble stick with a pair of pliers at the base of the wobble stick. (Figure 8, View A.) Turn the wobble stick counterclockwise to unscrew it. To attach a wobble stick, start threading the actuator to the head by hand. Then firmly grasp the wobble stick with a pair of pliers as shown in Figure 8, View B. Turn the wobble stick clockwise to within 1/8 inch of the end of the threads.
