4．主要功能：（Main Function）
A．副箱开启电源自动吹扫一定时间后（选择开关至于“正常”状态），主箱送电，当主箱内压力低于外部时，发出报警信号
，输出干接点信号，并自动补气，一定时间后，若压力差仍然低于设定值，自动切断供电电源。
B．在确认周围环境为安全的情况下，可以使用“旁路”状态，使得在主箱开门的情况下（主箱体内外压差为零），电源不切
断，以便对箱体内电路进行调整，测试。
A． A period of time is past after turning on power of assistant box, (select switch is“Normal” position ),
turning on power supply of main box. If pressure in the main box is lower than out, alarm signal is sent
and output dry point signal, then fill air to main box automatically after a period of time. If pressure
in the main box is lower than set point, turn off power supply.
B． it is confirmed that ambience is safety, “by pass” switch can be used, door of main box is open (pressure
of main box equal outer),power supply is turned on, in order to test circuit in the box.
