1. when the grid power is normal, ARD the standby charging status, ARD inverter automatic into the state, provide three-phase emergency power supply control system for elevator, power grid power supply recovery, ARD back to standby charging status.
2. When the dip switch SW1 (3 = off, 4 = on), received the lock closed relay signal delay 10s stop, if the signal is continuous work 180s stop; when the dip switch SW1 (3 = on, 4 = off), door interlock relay is closed from time to time after 15s stop; when the dip switch SW1 (3 = on, 4 = on), the door interlock closed relay signals from time to time after 30 seconds to stop.
3. The battery pack uses the free and free maintenance battery, the charging method is the pulse charge, can shorten the time of the battery to full charge, and the polarization of the positive and negative electrode of the battery can be reduced or reduced, improving the use efficiency of the battery.
