Specification: Item Type: Mechanical Time Switch Material: Copper, Iron, Plastic, Quartz Battery Type: 1.2V Lithium Battery x 1 (Equipped) Battery Model: Lithium Battery Battery Capacity: 300mAh Work Time after Power Failure: 150 Hours Operating Temperature: -10-50℃ Features: 96 Switch Segments Quartz Control Minimum Switching Time: 15 Minutes High Temperature Resistance: 150℃ Newly Upgraded Timing Switch Chip: More Accurate, Longer Service Life Circuit Safety: Accurate Timing Control, Efficient Specifications: Frequency: 50 60HZ (Commonly Used) Power Consumption: 110VAC: 1W, 220VAC: 2W Drive Method: Quartz Control Current Frequency Cycle: 24 Hours Switch Structure: SPST Load Manual ON OFF: ON AUTO OFF Switch Resistive Load: 20A ON OFF Program Setting: 15 Minutes Minimum Unit: 15 Minutes Shortest Interval: 15 Minutes How to Use: 1. Place the mounting hole (round belly hole) on the rear box or wood screw, and fix the two mounting holes (round) with wood screws. 2. When connecting the wires, break the PVC sheath and open the terminal cover. Refer to the connection method in the internal circuit diagram and manual for connection instructions. 3. When using conduits for pipeline connections, remove the PVC sheath for use. 4. This unit is a non waterproof structure; therefore, guard the unit. Use outdoors. Note: 1. Install the rechargeable battery before use. 2. Do not overload. 3. Use with a full electromagnetic switch. Operating Method: 1. The inner disc can only rotate clockwise, and its time is marked with the present time zone you are in (present time pointing to the 24 to 12 zone represents AM, pointing to the 12 to 24 zone represents PM). 2. One blue handle represents 15 minutes, pull outward to energize, can be pulled outwards in all areas where power is desired (time is identified by the outer ring 1 to 24). 3. When the mode is in off, all power is off, in on all power is on, and in auto, it will be controlled according to the set switch on time, so most of the time the mode should be set to auto. Issues: 1. Load does not turn on and off according to the set time: The time switch is in 24 hour format, and the confusion between AM and PM may be the cause, reconfirm the time (error is approximately ±3 minutes); 2. Hour hand is not functioning properly When the power reserve 2. Hour hand is not functioning properly: When the power outage compensation time (100 hours) is exceeded, the hour hand will stop and the inner circle needs to be readjusted until the current time. 3. Hour hand stops running, power on indicator light flashing: The battery has reached its lifespan and needs to be replaced. Wiring: Please refer to the wiring diagram in the instruction manual for the wiring of the lower power supply of the product and load (S1 connected to L1, S2 connected to L2). .
