4 1. ACTION PRINCIPLE < BLOCK DIAGRAM > (Operation principle) Commercial power is converted to DC power and charged into the battery. Charge control unit performs control of charge current, trickle current, protection timer, status LED etc. It also diagnosis battery conditions, and stops charging when the battery is faulty. When commercial power is supplied, the battery will be preliminary charged for 3 minutes, then rapidly charged. When the battery becomes full, or protection time(180minutes) is up, charge control unit stops rapid charge, and shifts it to trickle charge mode. Status LED winks during preliminary charge/rapid charge modes, and lights while battery full, or trickle charge. If the motor is drived battery-full or trickle modes, the system repeats the above action preliminary charge-rapid charge. When battery potential is down to terminal voltage (about 14V), it also shifts to rapid charge mode. Power interruption detector always monitors power supply, and functions as an emergency shutdown or emergency open valve according to the interlock unit status. Shut/open is optionally settable at emergency mode switch. While commercial power is being supplied, open/close is switchable with customer control signals disregard of interlock status. Even while commercial power is OFF, open/close is controlable by releasing interlock. 1 / 21

22 Caution when making wiring work 10-3 WIRING WORK Caution when making wiring work * Wiring work shall be made by a qualified person according to the electrical equipment technical standards. * Do not make wiring work in the rain or in high humidity environment. * Make a proper connection according to the relative connection diagram. * For all connections use fork crimped-on terminals. * Use a cable of outer diameter φ9~11 for the standard KOEI conduit. Otherwise, select a proper size conduit to just match the cable outer diameter. Unmatched conduit and cable may allow water ingress through the gap, resulting defective unit. Caution after connection is over After power and external signal input are connected, screw up the conduits firmly, then secure control unit cover with 4 fixing screws. Insufficient screwing may cause water ingress and defect to the unit. * Poly-vinyl tube etc.,if they are used, shall be well treated with water-prevention. Do not make such a piping or wiring as water flows along the tube or cable. 19 / 21

23 Caution for operation 11.TEST OPERATION 11-1 MANUAL OPERATION 1) Before making manual operation, cut off the Commercial supply, also pull off the battery connector. 2) Insert the manual lever handle into the hexagonal hole on the front cover (driving unit cover). 3) Direction is CW for close action, CCW for Open action. Confirm that the shaft turns smoothly without eccentricity. < HANDLE DIMENSIONS > Type Item BB-S BB-M BB-L Hex. hole (mm) No. of handle turns Length (mm) Materials SCS13 SCS13 SCS13 Caution Do not apply any excessive force on the handle beyond the action range (full close full open),for it may cause troubles POWER OPERATION( BATTERY ) 1) Confirm manually before making power operation that valve position is matching the opening meter. 2) Confirm that battery is correctly connected, then supply commercial power. 3) Confirm that the unit makes open/close action with external switch. 4) Open interlock circuit, and make commercial supply off. The unit now makes either Shut(full close) or Open(full open) action as preset at the emergency mode switch on the control unit. Confirm that it makes emergency action correctly. If the emergency circuit is short-circuited, emergency action will be disregarded. In this case,only external open/close switch will be effective. Caution after wiring is completed After power and external signal connection is completed, secure the conduit, also screw up the control unit cover with 4 screws firmly. Insufficient screwing may cause water ingress and defect to the unit. 20 / 21

24 12. MAINTENANCE AND INSPECTION ACT-U05E-3 Lubrication Battery Periodical operation As the unit is lubricated with long life, anticorrosive and water-protective lubricant ( Gleitmo 805K ) before shipment, lubrication is in principle not required. As the unit is perfectly sealed against electrolyte leakage, maintenance( refilling ) is not required. However, it is recommended to check every 3 months that there is no deformation, or rusting of the battery. It is difficult to determine how long the battery life is, because there are complex factors for it. However, it is suggested that the battery be changed about 4~5 years. In case a valve is very seldom operated, make periodical operation about every 3 months and confirm it is normal. 21 / 21
