4 投入运行
4.1 设置编码开关
当编码开关处于一个有效位置并且通过总线系统建立了通信
时,运行指示灯持续发绿光。当编码开关处于一个无效位置
或者中间位置时,运行指示灯起初不亮,之后变为红色。
4.2 调试设备和模块
4.2.1 用总线系统中的级联模块对设备进行设置
1. 用编码开关在级联模块上设置调整策略。
2. 必要时在其他模块上设置编码开关。
3. 接通全部设备的电源 (电源电压)
当模块的运行指示灯持续亮绿光时:
4. 按照随附的安装说明书将控制器投入运行并执行相关
设置。
5. 检查级联控制器上的设置情况并在必要时校准已安装的
设备。
4.2.2 用总线系统中 2 个或多个级联模块对设备进行设置
设备中可最多安装 16 个热源。这种情况下存在一个上级级联
模块和 1 4 个下级级联模块。
1. 用编码开关在下级级联模块上设置调整策略。
2. 将下级级联模块上的编码开关设置为 10
3. 必要时在其他模块上设置编码开关。
4. 接通热源电源。
5. 接通模块和控制器的电源。
6. 按照随附的安装说明书将控制器投入运行并执行相关
设置。
7. 检查级联控制器上的设置情况并在必要时校准已安装的
设备。
4.3 上级级联模块上热源 / 下级级联模块的状态显示
除了编码开关,模块上有 4 LED,显示连接的热源 / 模块的
各种状态。
LED 1 2 3 4 显示已连接的热源 / 下级级联模块上相应
模块的状态:
熄灭:断开连接或无通信
红色:找到热源,但连接中断或热源处存在故障
黄色:热源已连接,无热量要求
黄色闪烁:找到热源,存在热量要求,但燃烧器关闭
绿色:找到下级模块或找到热源,存在热量要求,燃烧
器运行,加热装置激活
绿色闪烁:找到下级模块或找到热源,存在热量要求,
燃烧器运行,热水制备激活
4.4 下级级联模块上热源的状态显示
除了编码开关,模块上有 4 LED,显示连接的热源 / 模块的
各种状态。
LED 1 2 3 4 显示热源的相应状态:
熄灭:断开连接或无通信
红色:找到上级级联模块或找到热源,但连接中断或热
源处存在故障
黄色:热源已连接,无热量要求
黄色闪烁:找到热源,存在热量要求,但燃烧器关闭
(例如,热源脉冲锁定装置已激活)
绿色:找到热源,存在热量要求,燃烧器运行,加热装
置激活
绿色闪烁:找到热源,存在热量要求,燃烧器运行,热
水制备激活
先正确连接所有电气接口,之后再执行调试!
遵守设备所有部件和组件的安装说明书。
所有模块均设置完成后再接通电源。
提示 : 泵毁坏会造成设备损坏!
接通前注满设备并排气,这样泵不会干运行。
当编码开关上级模块 MC 400 设置为 10 并且热源和
该模块间存在直接总线连接时,设备无法调试。
如果安装了 IGM,必须注意下列几点:
IGM 上设置所连接设备的最大和最小功率。
最大功率的最小设置值为 5kW,否则级联控
制装置无法使用 IGM
如果所连设备为双点设备,设置最大功率 =
最小功率。
提示 : 泵毁坏会造成设备损坏!
接通前注满设备并排气,这样泵不会干运行。
