1.总体特性 1.1概述 μAC是一种电子控制仪表,可用于控制单元式精密空调机组(由1或2台压缩机或其它冷源、1或2组电加热或其它热源、比例式/开关式加湿器、开关式除湿执行元件、开关式/连续式调速冷凝风机等构成),是CAREL公司较新推出的实现精密空调控制较经济的产品。 主要功能: ? 根据回风温/湿度实行控制; ? 控制"掩体式"空调机组实现节能或冷/热量补偿; ? 除湿的管理; ? 送风机调速; ? 所有报警的处理和记录/查询(较多达300条); ? 多达6台同类机组的轮值管理; ? 每周7天,每天4个时段的不同设置; ? 可以组成集中监控和远程监控系统(RS485标准)。 被控设备: ?1~2台压缩机或冷源调节阀; ?1~2组电加热器或热源调节阀; ?送风机开关式或比例式调节; ?加湿器开关式或比例式调节; ?开关式除湿设备; ?报警设备。 选件: ?RS485串行板; ?时钟/存储板,用于报警记录及时区管理; ?风机控制模块; ?程序转载器。 编程: 全部控制参数可由前面板按键设定,或从程序转载器下载,或由串行线路导入。 2.μAC的用户界面 μAC由显示屏和控制板组成,二者集成为一体,如上图所示。 2.1显示屏 显示屏提示机组的主要测量值、状态和响应。 右图给出显示屏的全部符号和信息,在控制器上电时即会出现。下面描述这些符号和信息的含义。 3 房间温度。编程过程中,显示参数值。 温度测量单位,摄氏或华氏。 房间湿度。编程过程中,显示参数代码。 相对湿度的测量单位。蜂鸣器激活。 计时器**限。 时区控制下的停机状态。 时区控制激活。 外部触点(远控开关)状态,ON:机组允许开,OFF:机组待命。 用于表示所显示的数值是温度,即当无此标记时显示的是设定值。 时区生效。 除湿已启动。 风机已启动,旁边的标尺是风机转速的百分比。 制冷已启动。1或2是压缩机台数, 旁边的标尺是冷源阀门的开度百分比,或在掩体式机组中是新风风阀的开度百分比。 制热已启动。1或2是电加热组数, 旁边的标尺是热源阀门的开度百分比。 加湿已启动。旁边的标尺是蒸汽产量的百分比。 编程(参数设定)状态。 口令设定;参数修改被禁止。 时钟功能中,表示一周内的日期序数。 显示时钟;时钟设定。 2.2状态指示灯 右图是前面板的LED指示灯,反映控制器的主要状态:电源开启、报警发生、远控开关的输入状态等。 Line(电源,黄色):控制器上电。 Alarm(报警,红色):机组报警(仅当蜂鸣器被激活时显示屏上的喇叭标志才出现)。On(运行,绿色):机组经按键或上级监控系统(视乎EEPROM的变量)指令而开机。但有效的机组运行状态 取决于远控开关、有效的时区、以及来自主令机组的待命条件(如果一系列机组组成轮值系统),一旦真正运行,显示屏出现风机的标志。 显示屏上的ON-OFF标志仅表示远控开关触点的状态。 2.3按键 on/off:若机组在运行中,按一下此键使之进入待命状态,反之重新启动。 4 型号 PJEZC00000 PJEZC00100 PJEZC0H000 PJEZC0H010 PJEZC0H110
