Application SW08020: Pump PID 2 [Advanced Pump PID Control]

System Requirements:

ZENER 8000 with the Application: Pump PID 2 and an option board (AQ/AF08001) fitted.
1.
A pressure transducer and a pressure gauge (for calibration purposes) located between the pump and
2.
any discharge valves.
A 4-20mA pressure transducer. However different devices can be used by varying the appropriate
3.
parameters.
Non return valve required on the suction side of the pump. All non-return valves are functioning
4.
correctly and there are no leaks in the pipework. With all field taps and valves turned off the pressure
holds.
The motor & pump are in good working order.
5.
Any non-return valve on the discharge side of the pump must be located between the pump and the
6.
transducer.
The internal high & low pressure trips are for operational purposes only. Separate and independent
7.
methods must be employed to prevent economic loss. A pressure relief valve is recommended.
Optional control input available for 'Bore level'. External level sensing device required.
8.
Optional control input available for 'Flow Switch'. This provides a more direct idle control. A flow
9.
switch may be required with multiple set points or a variable set point.

Control Wiring:

Note: All control wiring should be screened.
*************************************************************************
Ensure the ZENER 8000 is in local mode (remove link in terminal 5) to prevent
operation while programming and performing preliminary checks..
