At its simplest, RTC for a network consists of a single range and rules.
The following example shows the RTC for starting a pump when the level in a chamber exceeds a defined depth.
Under this example, the pump will be switched on when the level at node D equals or exceeds 20 mAD. When the level at D falls below 20 mAD the pump will be switched off by default.
The scenario is defined by adding components to a fixed pump regulator in the RTC Window Editor.
|
Component |
Parameters |
Effect |
|---|---|---|
|
RANGE 1 |
Range type: Z - height above datum Location node: DMinimum: 20 mMaximum: |
TRUE if level at node D is greater than or equal to 20 mAD |
|
RULE 1 |
Condition: _default_ Rule type: OFF |
Default status of pump is OFF |
|
RULE 2 |
Condition: RANGE 1Rule type: ON |
Switch pump ON if RANGE 1 is TRUE |
- Range 1: Defines Node D as the control point with a minimum value of 20 m
- Rule 1: Unless subsequent rules are TRUE, the pump will be set to the default status of OFF
- Rule 2: Switches the pump ON if the level at node D is at or above 20 m
