Air-Conditional Chiller Pump Controller
B605D Series(220V)
Product Description:
B605 series controller is specially designed for central air-conditioning water circulation system to realize constant pressure differential control. It can confirm the system to adapt to the change of air-conditioning load, with the advantage of rapid reaction, little influencing on temperature and humidity, ensuring the balance of the system, effecient energy-saving and so on.
Input Voltage/Output Power Range:
Single phase 220V input,3 phase 0-220V output: 1HP-3HP(0.75KW-2.2KW)
Three phase 220v input,3 phase 0-220v output:1~70HP(0.75~55KW)
Applications:
Central air conditioning circulating system.
Features:
1. Relay Output: 2 Outputs.
2. Professional design based on users' needs, suitable for differential pressure control, simple operation.
3. Running automatically when power on.
4. Programmable Analog Input:
AI1:0~10V or 0~20mA input
AI2:0~10V or 0~20mA input
5. Multi-Pump Control: can realize 1 master and 5 slaves combine work at most.
6. Constant Differential Pressure Control: PID, control based on feedback source of (AI1-AI2).
7. Alternate running balance every pump's running time, prolong service life of the pump.
8. Verious of water supply fault alarm functions:high pressure, low pressure, low level, transducer error etc.
9. As many as 22 kinds of fault protection functions: over current, over voltage, low voltage, phase failure, over load etc.
Dimension:
Keypad Description:
Daily Maintenance:
In order to prevent the fault and prolong the service life of the controller, user shall daily
inspect the controller. The following table indicates the inspection content:
Replacement of Wearing parts:
Fans and electrolytic capacitors are wearing parts; please make periodic replacement to ensure
long term, safety and failure-free operation. The replacement periods are as follows:
1. Fan: must be replaced when using up to 20,000 hours;
2. Electrolytic capacitor: must be replaced when using up to 30,000~40,000 hours.
