HOW TO CHANGE THE CORD OUTLET DIREC- TION FOR CONNECTOR TYPE The cord outlet direction is interchangeable both right and left sides. The direction of connector cord is set to the right when it is shipped. When it is used left side direction, follow the next procedure. Cord outlet direction (Right side) Step 1 Fitting metal Body Step 2 HL (AZH) Cramp Terminal cover Push down the fitting metal while pulling it horizontal direction. Step Turn the terminal cover at an angle of 0 degree. Follow the procedure. Do not pull the terminal cover. Do not rotate the terminal cover many times. Do not loosen the terminal screw. Cord outlet direction (Left side) Step 4 Attention Attention Seal rubber Do not put the lead wire between terminal cover and body. Put the seal rubber at the right place. Press up the terminal cover. Confirm the fitting metal is on tightly. If it is loosen, it might be cause of the trouble. INDICATOR LIGHTING CIRCUIT (Connector type only) 1) See the circuit diagram. 2) Voltage across the terminal No. and No. 4 shall not exceed 24 V DC, with the indicated polarity in the circuit diagram. ) The LED is turned on when the switch is at a free. The LED is turned off when the switch operates. 4) Applicable power source is 24 V DC. Use it with care on leakage current. The leakage current is approx. 1.5 ma at 24 V DC.

CAUTIONS Die cast case 1) Do not expose HL limit switch to hot water (over 60 C 140 F) and in a water vapor environment. 2) Avoid the place where organic solvents, strong acid, strong alkali liquid and vapor may attach to the products directly. Prevent using the HL limit switch in place where inflammable or corrosive gas will be generated. ) Do not change the operating by bending the actuator. 4) If OT is too big, the life of limit switch will be shortened by switching friction. Use it with enough margin of OT. 70% of OT standard value will be good. 5) Attach the terminal cover securely to the body with the metal stop latch to the projection of the body. 6) Confirmation test in the actual application is highly recommended. 7) Do not use the switch in a silicon atmosphere. Care should be taken where organic silicon rubber, adhesive, seling material, oil, grease or lead wire generates silicon. Plastic case 1) Do not use in water or oil. Do not place the switch where it is always exposed to water or dust splash. 2) Do not expose HL limit switch to hot water (over 60 C 140 F) and in a water vapor environment. ) Avoid the place where organic solvents, strong acid, strong alkali liquid and vapor may attach to the products directly. Prevent using the HL limit switch is place where inflammable or corrosive gas will be generated. 4) Do not change the operating by bending the actuator. 5) If OT is too big, the life of limit switch will be shortened switching friction. Use it with enough margin of OT. 70% of OT standard value will be good for use. 6) Attach the terminal cover securely to the body to the extent you can identify the clicking or locking sound. 7) A confirmation test in the actual application is highly recommended. ) Do not use the switch in a silicon atmosphere. Case should be taken where organic silicon rubber, adhesive, sealing material, oil, grease or lead wire generates silicon. 2
