Emerson XWEB3000 EVO Operating Manual page 60

- Execution Interval: cycle time for sending the dew-point set (in minutes)
- Destination Class: class of devices receiving the dew-point set value
- Control Device: device for calculating the dew-point set value. Should the XH50/55P box be selected,
the calculation is performed by the same device that must be specified with field "XH50/55P Device".
This controller is connected to a temperature and humidity probe in the room. Should this device not be
available, it is possible for the XWEB-EVO to calculate the Dew-point Set value, by specifying the
variables from which the room temperature and humidity values are to be read. They are indicated with
parameters Temperature/Humidity controller and Temperature/Humidity Input.
- Constant Set Offset: offset at Dew-point set value added
- Min./Max. Set: limit values of Dew-point set. Should these values be higher or lower, they are sent to the
controller of the class configured for this engine
With keys:
- Enable/Disable Engine: it enables/disables the dew-point engine. Visual feedback is provided on the
engine's state on the top part of the window, as demonstrated below.
- Close: it closes the window, saving any modifications applied to the parameters. Attention: the
modifications made to the parameters must be saved on the system before being applied by the system
itself. To save, run the save operation of the project (of dew-point)
- Cancel: it closes the window, cancelling any modifications applied to the parameters

Project saving (of Dew-point)
All dew-point management parameters are part of the same project. Every time a parameter is modified, for it
to be applied to the system, run the project save operation by accessing the menu ProjectSave

Control of the project log (of Dew-point)
ERRORS:
Lists the possible errors that the system can send to the "Result" column
"Valid" => in the value column, the value calculated and sent to the central device is shown.
"Syntax error" => There is an error in the formula defined by the user. The mathematics is not developed.
"No device data" => There is no data from the device and the mathematics cannot be developed.
"No link device" => As above, since the device is a NoLink
"Device OFF" => As above, since the device is in Off mode.
"Math div by 0" => The mathematics development is stopped due to a division by "0"
"Value not allowed" => The values for the formula variables are not permitted (out of range)
"Mathematic" appears in the "Device" column
