The control process of lifting platform decline is similar with the above process, as long as pressing lifting platform declines button PB2.
In lifting platform rises or falls, as long as triggering lifting platform limit switch LS1 or LS2 disconnection, relay KA5
Coil losing electricity；Relay KA5 normally opened contact KA5-1 is disconnected, and frequency converter MC1 loses enable signal；Relay KA5 is normally opened simultaneously
Contact KA5-2 is disconnected, so that contactor KM1 coil blackout, contactor KM1 main contacts KM1-1 is disconnected；Lifter motor M3 just stops
Only run.
