Control the Starting and stopping of an auxiliary pump

The PI regulator output (frequency reference

of the variable pump) is used to control starting or stopping of an auxiliary pump with hysteresis

It allows the joker pump stop when the flow is equal

to zero ( all auxiliary pump at stop)

It allows the restarting of the Joker pump when a flow

Irrigation

Fast acting PID control

- Fast shut down algorithm prevents pressure overshoots when fast acting valves close

Auto Shut Down Algorithm

- The system will pump unsupervised for a selected time, after which it will automatically stop

Trang 18

Irrigation

Flow Limitation

- Used when flow must be restricted to a particular level The system operates in pressure control as long as the measured flow is below the flow limit At that point speed is adjusted to stay below the allowable flow

Set point range limitation

- Irrigation pumps may be able to pump up pressure to above the withstand pressure of the weakest part of the distribution system Unwanted high setpoint selection can be prevented by dialling the correct range

Jockey Pump control

- For low demand situations, a jockey pump can be used

in conjunction with a lead pump system The Jockey pump works in on-off control between two pressure setpoints

Night and Day algorithm

- During night time, the system operates in fixed speed between two pressure setpoints In case of excessive demand, the system reverts back to normal lead pump operation

Crops can be protected from frost damage by sprinkler or mist systems

If enabled, this feature will automatically start the pump

if the temperature, measured via an analogue input, decreases below the frost setpoint for a certain time period

An instant start temperature can also be set for protection against rapid temperature changes

Once run is initiated only manual shutdown is possible

Pressure Boost mode

- For long supply lines or high rise buildings, it may be required to boost the pressure at regular intervals The inlet pressure is monitored and the pressure reference

is reduced if the inlet pressure is low

Slow response for staging and de-staging

- Staging and de-staging is triggered by pump speed and pump pressure error and can be delayed to guarantee smooth action

Friction compensation

- The pressure setpoint is adjusted to overcome losses in the reticulation system Continuous adjustment and/or step compensation can be selected

Setpoint Ramping

On transition from any state into PID control, the reference is ramped from the current feedback level to the required setpoint This prevents an unwanted initial large error

Pipe fill algorithm

On initial start-up pipes may be empty Starting PID control under these conditions would result in the PID ramping up, due to a low feedback Pipe fill runs the system at a preset speed until a start pressure is reached and then transfers into PID control.

or mono joker and auxiliary pumps permutation with the limitation of the operating time

Staging and de staging

Staging and de staging conditions can be based on speed, pressure, PID error or any combination of these A delay allows for further fine tuning During this operation, the speed of the variable speed pump is set to adjustable values This ensures smooth pick up and drop off for fixed speed pumps

Reduced Overshoot

Reduced Undershoot

4 Pump Compatibility

If pumps with a flat H-Q curve are used, it may be difficult to identify a no demand situation.This algorithm detects a no demand situation via the response to a step decrease in setpoint.

Some pump systems require the main pump to

be primed with fluid prior to starting to prevent them from running dry for too long
