6．运行的逻辑控制：
a .运行逻辑控制包括自动程序顺序控制方式下设备的启动和关断逻辑、手动单步控制方式下设备的启动和关断逻辑及联锁控制逻辑。
● 启动逻辑
海水泵启动 整流器启动 连续加药泵启动 冲击加药电动阀开启 进入运行监控。
此逻辑顺序适合于所有启动方式。
● 关断逻辑
整流器关断 加药泵关断 海水泵关断。
此逻辑顺序适合于所有关断方式。
b.联锁控制逻辑
联锁控制逻辑包括：
● 备用切换
海水泵、加药泵均有备用设置，在启动或运行过程中，如果运行设备出现故障，则关断运行设备，同时自动切换到备用设备。
● 时序逻辑联锁
各设备的启停操作必须符合工艺要求的时序逻辑。
● 顺序逻辑联锁
按启动逻辑和关断逻辑，方可顺序操作设备，如果违反顺序，则操作命令不能执行。
如：必须先开海水泵后，才能开启整流器。反之则不能。
● 条件逻辑联锁
按启动逻辑和关断逻辑，一些设备的启动或关断必须满足一定的条件，若条件不满足，则操作命令不能执行。
如：海水泵启动后，必须在流量、压力、温度条件满足时，方允许启动整流器。
