Flushing Scheduler - Schedule page

This page is divided into three sections:

The page is opened by clicking the Schedule tab on the Flushing Scheduler.

Actions section

This section contains a grid of the actions in the schedule. The buttons by the side of the grid are used to add, delete, and edit the order of the actions.

Item Description
Actions grid columns
No.

Read only field.

Number of the action. Actions are listed in sequence order.

Name

Descriptive name for the action.

Fixed Time

If checked, fixes the start time of the action. A start time must then be specified in the Date/Time column of the grid for this action.

If unchecked, the Date/Time will be calculated.

Date/Time

Start date & time for the action.

If the Fixed Time option has been checked, this must be defined by the user.

If the Fixed Time option is unchecked, a calculated start time will be displayed.

Minimum Interval

Minimum time interval between the end of the flushing action and the start of the next.

By default, set to the global value specified in the Minimum between action interval field on the Criteria & Hydrants page.

Actions buttons

Add

Enabled if there is a single action selected or when there are no actions selected.

  • When there are no actions selected, clicking this button will add a row to the bottom of the grid.
  • When there is one action selected, clicking this button will display the Add Action dialog, letting you choose the position of this action relative to existing ones and whether to copy flushing points and links to close from the preceding action.

Up

Enabled when a single action (other than the first action) is selected.

Clicking this button moves the selected action one place up the actions sequence.

Down

Enabled when a single action (other than the last action) is selected.

Clicking this button moves the selected action one place down the actions sequence.

Delete

Enabled when one or more actions is selected.

Clicking this button deletes all selected actions.

Selected Action section

This section contains a number of tabs that display details of the action currently selected in the Actions grid. The buttons below the tabs are used to provide validation and additional information for each action.

Item Description

  • Default - opening of hydrant is to be set to achieve required flushing velocity

  • Fully Open - hydrant is to be fully opened when flushing

  • User Flow - opening of hydrant is to be set to achieve the required flow entered by user

Required Flow

Enabled if Flow Setting is set to User Flow.

This is where you enter the flow required from the hydrant for the flushing process.
