System Requirements - Zener 8000 Application Manual

Application SW08024: PID Irrigator

System Requirements:

ZENER 8000 with the Application: "PID Irrigator" fitted with an extended features board (AF08001).
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 valves may be located as determined by the application. Their location does not affect
4.
pressure regulation.
The motor & pump are in good working order.
5.
The "HI PRESSURE" trip and "PRESSURE ERR" trip are for operational purposes only. Separate and
6.
independent 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.
7.
Optional control input available for 'Flow Switch'. Closed contact indicates flow.
