本应用程序适用于冷凝器和液体冷却器
风扇速度根据以下条件控制的应用:
从传感器接收的信号。请参见下图。
在自动模式下使用直接速度参考时
速度基准必须连接到模拟输入1(AI1)
并且用数字输入1(DI1)给出启动命令。在里面
切换/断开模式、速度参考和起动
通过控制面板(操作员键盘)发出命令。
如果使用过程PI(D),则必须连接反馈信号
至模拟输入2(AI2)。默认情况下,设定点是从
控制面板,但也可以更改为模拟输入1。
工艺PI(D)必须通过以下方式进行调试和调整:
参数(组40:过程PID设置1)或使用PID
控制助理(推荐)。

Condenser This application macro is for condenser and liquid cooler applications where the fan speed is controlled according to the signals received from the transducer. See the figure below. When using a direct speed reference in the AUTO mode, the speed reference must be connected to analogue input 1 (AI1) and the START command is given with digital input 1 (DI1). In the HAND/OFF mode, the speed reference and START command are given through the control panel (operator keypad). If process PI(D) is used, the feedback signal must be connected to analogue input 2 (AI2). By default, the setpoint is set from the control panel, but it can also be changed to analogue input 1. Process PI(D) must be commissioned and adjusted with parameters (Group 40: PROCESS PID SET 1) or using the PID control assistant (recommended). © Copyright 2007 ABB ACH550-01 User's Manual Application macros and wiring 105 1 SCR Signal cable shield (screen) 2 AI1 External reference 1: 0(2)…10 V or 0(4)…20 mA 3 AGND Analogue input circuit common 4 10V Reference voltage +10 V DC 5 AI2 Actual signal 1: 0(2)…10 V or 0(4)…20 mA 3 6 AGND Analogue input circuit common 7 AO1 Output frequency: 0(4)…20 mA 8 AO2 Output current: 0(4)…20 mA 9 AGND Analogue output circuit common 10 24V Auxiliary voltage output +24 V DC 11 GND Common for DI return signals 12 DCOM Digital input common for all 13 DI1 Start/Stop: Activation starts the drive 14 DI2 Run enable: Deactivation stops the drive 2 15 DI3 Constant speed 1 (par. 1202) 1 16 DI4 Start enable 1: Deactivation stops the drive 2 17 DI5 Start enable 2: Deactivation stops the drive 2 18 DI6 Not used 19 RO1C Relay output 1 (par. 1401) Default operation Started => 19 connected to 21 20 RO1A 21 RO1B 22 RO2C Relay output 2 (par. 1402) Default operation Running => 22 connected to 24 23 RO2A 24 RO2B 25 RO3C Relay output 3 (par. 1403) Default operation Fault (-1) => 25 connected to 27 26 RO3A 27 RO3B 1 Not available if PID is activated 2 Disable/enable with parameters 1601, 1608 and 1609 3 The sensor for AI2 is powered externally (not shown in the figure).
