		REGULATORS 1. While my regulator’s working, some weird noises‘re coming. Is my regulator working properly? Some weird noises coming from the regulator indicates that there’s not a fault but a fluctuation & the excessive feedback due to the lessening of the pivots of the variac and the motor. In this case the adjustment of the sensitivity pot is important. 2. The regulator occasionally shuts off. What’s the problem? When the regulator output voltage reaches dangerously high levels, the regulator shuts down. The reasons why the regulator shuts down are : • High voltage cut off adjustment may change in time. • There may be an extraordinary circumstance in mains. • There may be a damage in the regulator & the regulator may totally be out of control. • The line where the regulator is connected to mains may not be thick enough. 3. High & low voltage protection circuit, missing phase & delay circuit are found in every ALFA GAMMA regulator. Are these circuits indispensable? The purpose of using regulator is to protect valuable devices. Regulator regulates the voltage adjustment adjustment to prevent high-priced devices getting harmed. The missing of these protection circuits above in your regulator is like driving a car without brakes. If you ignore these essential circuits in order to decrease cost, you’ll regret it in the long run. 4. Fuses have been blowing frequently. Why? Fuse blowing indicates that the voltage in the mains’s going down & the regulator is in need of drawing more current in order to provide the same power. Another reason why the fuses have been blowing frequently is the excessive load. 5. You suggest me the regulator which is three times more powerful than I had it measured in my working place. Why don’t you suggest me the regulator which has a power in accordance with the measured one? The working places where the engines are used need more power because the engines draw more current when they work the very first time.The engines actually draw current three times more than the measured one in the working places. If you prefer a regulator which we don’t suggest, then fuse’ll blow, variacs will not work properly. If you consider our suggestions, you’ll avert time loss. RECTIFIERS 1. How do I change my rectifier? Rectifiers must be charged 1/10 of the accumulator amp/h capacity. 2. Is the accumulator charge cut off circuit essential? Yes, it’s essential. If the charge is not cut off, it may harm the accumulator. BLASTING MACHINE 1. How do I charge my blasting machine? It’s essential to charge your blasting machine when the accumulator weak led glows. If you leave your blasting machine uncharged for a long time, the circuits will be damaged. It’s essential to charge your blasting machine once a week & 2-3 hours before every use.   türkçe           english
