Swatch dual power switch is in working condition common failure analysis of several maintenance and troubleshooting to ensure the reliability of dual-supply operation, periodically (recommended every two months) to conduct a test to confirm the dual power switch is normal. To ensure continuity of supply load. Troubleshooting common when it comes to dual power does not work, please see the list of the first fault. If you still can not be resolved, contact me or agents. Tripping the alarm normal or emergency power supply due to circuit breaker fault trip, warning lights "NB" or "RB" appropriate trip indicator light, but does not make the power conversion. Fault alarm is automatically released after discharge, but you must manually reset the circuit breaker. Fire is reset when the fire command center input control unit, will make two-way circuit breaker trips. Fire signal must be DC + 24V, disappeared after the fire command, you must press the reset button on the control unit to automatically re-entered the running state. User connection: 1. It is recommended when the switch is installed in the box to the mounting plate bolted to maintain. , 2. The switch with a common power supply, standby power indicator, indicating the circuit breaker is closed, the circuit breaker trip indication also provides an external output terminal (active) users of these indicator lights can be determined according to the required external dual power specific circumstances dual supply operation, a user can refer to the product wiring diagram. 3. The ground wire must be reliable in order to ensure operator safety. Dual power switch device maintenance, maintenance: 1. Dual Power Automatic Transfer Switch using the four-loop units to designate a person responsible for the maintenance, management, listing unnamed. Ensure the switch maintenance quality, ensure the normal operation of local fan. 2. Dual Power four-loop automatic switch maintenance personnel should check every day whether the switch housing smashed (hit) deformation, loose fasteners, grounding is qualified, whether the proof requirements; whether local fan sound normal; whether the upper switch watering and so on. 3. Shake test once a month must be designed for cable, designed for open and, local fan motor insulation, the insulation was lower than when the corresponding 10MΩ / km, 2MΩ, when 0.5MΩ, must be replaced. 4. Use the unit must be four-loop dual power switch automatically switch the test done once every switch must be reset after the end of the test, ensure that the host job, be prepared auxiliary. Found in the test must be the first time does not automatically switch notification mine control room and electrical management company and arrange for someone to guard next to the switch, but to arrange immediately, otherwise the penalty units 2000 yuan / times, electromechanical responsible person 200 yuan / times, the responsible person 200 yuan / times. 5. Electromechanical Management Company from time to time to check the power of four dual-loop automatic switch test record, for the record without making the test or are incomplete, the person in charge of a penalty unit electromechanical 100 yuan / day, responsible for 100 yuan / day use of dual power, and the whole mine criticism. 6. Every ten days to four-loop automatic dual power switch once maintenance, overhaul and make a record penalty units without making responsibility overhaul 2000 yuan / time, the person in charge electromechanical 200 yuan / times, responsible for 200 yuan / times, because not overhaul the consequences are serious according to relevant regulations mine. 7. switch, line, local fan conduct regular maintenance dual power supply manufacturers must submit an application report power outages by using the unit, after the mine will produce balanced approval from maintenance, eliminate unplanned maintenance outage dual power accessories manufacturers | only Thai Electric | Chongqing dual power provided by the Shanghai-Thai Industrial Co., Ltd.
