Mini Dual Power Switch Features: Mini dual power switch with manual and automatic control of operating two control states. Manual operation sub-manual control, emergency handle operation; automatic control operating points from the vote since the complex, mutual backup, double points. Outside the control of the control terminal optional relay contacts normally closed or normally open state-owned generator start command is given. External terminals can be achieved by indicating the fire points / Fire close and various states. Mini dual power switch Warranty: warranty period, occurs in the normal state using mini dual power switch product fails, the user can produce this warranty card and invoice or receipt (copy), and enjoy free in the goods purchased at maintenance services. The following situations need to pay the maintenance fee: 1, the use of this product under normal conditions and failure, but those who have exceeded the scope of the warranty period. 2, under abnormal conditions, for example: man-made damage or high temperature, high pressure, humidity and other environmental use under normal circumstances, as the damage to pay maintenance. 3, non-product quality problems caused by faults and damage. 4, not in accordance with the instructions in the use of methods and precautions caused malfunctions and damage. The following cases are not within the scope of the Company's Warranty: 1, without our consent, without permission removable mini dual power switch. 2, non-manufactured products sold. Dual Power four-loop automatic transfer switch installation: 1. Coal Lane, half coal roadway must install KBF-4 × 60 Dual Power four-loop automatic switch. 2. The principle of four-loop dual power switch automatically switches on the implementation of the principle of "who use, who install, who maintains" dual power, under special circumstances by the balance of ore unit installation and maintenance. 3. Dual power supply circuit automatically switches installed four position switch Chint NH40-100A dual power, determined by the local fan position electromechanical management company based on pass defense companies. 4. Dual Power four-loop automatic switch as proof electrical equipment dual power automatic transfer switch, before entering the well, must work together to carry out the following special inspection by the Electrical and management company, and use of, any one of the non-compliance prohibit loading to go down: a) Check the electrical explosion-proof performance. Comply with the requirements of the electrical explosion-proof, explosion-proof certification must be affixed; b) a current test. Must ensure that when the power switch is sensitive and reliable test automatically. c) Check the switch insulation. Switch insulation value of not less than 2MΩ. 5. Each four-loop automatic dual power switch and power supply line laying, must be performed in accordance with the mechanical and electrical power management systems, according to the company a diagram. Main, auxiliary power supply should come from different local fan designed for transformer, prohibited the main and auxiliary power reversed. 6. strictly in accordance with the Electrical and Mechanical Management Company issued the "Notice Relay Setting" in the relevant parameters. 7. Each tunneling face local fan must implement wind power interlock with all non-intrinsically safe electrical equipment in the face, to ensure that sensitive and reliable wind power interlock. Otherwise, stop the tunneling face all power supply units concurrence 2000 yuan / time, the person in charge 200 yuan / times, electromechanical responsible person 200 yuan / times, responsible for 200 yuan / times. 8. pass defense company by monitoring teams in the opening stop switch automatically install sensors, signal transmission to the switch ground control room, intuitive reaction local fan running. 63A dual power, only Tai Electric, Shanghai, Fuzhou, dual power only by the Thai Industrial Co., Ltd.
