discharges and accidental failures.

MW16, 26,36 series lifting electromagnet coil steel installation and operation
Installation: Installation of this device suitable for indoor cranes, including magnetic power protection devices, battery and battery box should be installed on the crane girders, ease of maintenance, or other appropriate place with good ventilation; meter box, the controller should be installed in the driver room or operating room; electric flute should also be installed in the cab or operator easy to hear the place.
4.2 Wiring: Wiring diagram according to the external current value of the standard specifications select the appropriate voltage of 500V or more wires, according to the attached external wiring diagrams good line, pay attention to the wiring between the transformer and the rectifier can not pick the wrong; particular attention and the polarity of the wiring between the battery can not be wrong; wherein between P2 and N1 only two batteries. The contacts should be connected securely and should be clearly marked.
4.3 Charging: Check the wiring is correct, close the filling cabinet automatic air switch QF1, QF2, then this device to charge the battery automatically, automatic charging cabinet panel ARC-E1 on the LED display when the state of charge; this on the door and when the meter box on the voltmeter and ammeter should be a corresponding current and voltage display; strong charge when the current security should 0.1CA about voltage between 220V to 260V are normal; float charging current at about 0.5A, the voltage between 220V to 260V are normal. Because the factory automatic charge control board ARC-E1 on the various parameters have been set, so it is best not move automatically charged Dashboard ARC-E1 on the various settings.
4.4 Suction operation: Press the drawings connected and check all connections for suction correct before operation. To ensure safety, should first control handle is set to "discharge" position, check the power supply meets the requirements, check HL1 is lit; observe the state of charge, the charge voltage, charge current, charge state when strong charge into the floating charge state a certain time After that first charge the battery is fully charged, ready to be put into operation, will run the electromagnet is attracted to the material on the handle is set to "suction" position, drum separator drawing materials, the material should be placed in the electromagnet runs to position
The handle is set to "discharge" position, the solenoid discharge, discharge time is 2-3 seconds.
4.5 blackout test: the electromagnet hanging material to the specified location to run the process, in case of outage or main part of the fault rectified so that the voltage fed to the solenoid down to a certain value; or man turn off the power, standby power immediately and automatically inputs, to ensure that the material will not be drawn down, the meter box HL4 bright lights, electric horn beep alarm. Work for the inverter switches SA1, AN21-based decentralization button hook, power protection SA1 placed under magnetic state inverter working position, press AN21 button, the inverter converts the DC reverse into three-phase alternating current, the AC brake to open the lifting objects fall to the ground.
4.6 After the operation is completed, it can be down to the designated location electromagnet, the controller handle to the "discharge" position, put down the material, the automatic air switch QF1, QF2 off, to avoid unnecessary discharges and accidental failures.
