Familiarising yourself with the icons on the main menu screen

Along the top of the window, you will notice several icons: This icon creates a new configuration and lists it in the ‘Configurations’ window.

This icon opens configurations and loads them in the ‘Configurations’ window. This function is

used for configurations not listed in the ‘Configurations’ window (usually a configuration loaded

from another PC). Compatible files will have the ‘.dmpu’ file extension.

This icon will allow you to download configurations to the AmpCom system that are listed in the

‘Configurations’ window. This same icon also allows you to upload configurations from the

AmpCom system and save them in the ‘Configurations’ window.

This icon will allow you to save configurations to a different location on your PC compared to the

default location the software saves files to. Note: Once configurations are created or opened from a

different file location, they are automatically saved to the default location.

This icon is used to modify a configuration. Select a configuration from the ‘Configurations’

window then click on this icon to begin to program your AmpCom device.

This icon will remove configurations in the ‘Configurations’ window and from the default

save location.

Click ‘OK’.


Page 41

Hands-On Training Lab Note: Up Control: When the measured value exceeds the

‘Over Level’ and after the ‘ON delay’ time expires, this

alarm will activate. The alarm will not reset until the

measured valued drops below the ‘Under Level’. Down Control: This input type is the reverse of Up

Control. When the measured value drop below the

‘Under Level’ and after the ‘ON delay’ time expires, this

alarm will activate. This alarm will not reset until the

measure value exceeds the ‘Over Level’.

In Control: This alarm will activate when the measured

value is in between the ‘Under’ and ‘Over’ levels and after

the ‘ON delay’ time expires. This alarm will reset once the

measured value is above the ‘Over Level’ or below the

‘Under Level’.

Out Control: This input type is the reverse of ‘In Control’.

This alarm will activate when the measured value is

outside the ‘Under Level’ or ‘Over Level’ and after the

‘ON delay’ time expires. This alarm will reset only when

the measured value is above the ‘Under Level’ and

below the ‘Over Level’. These ‘Input types’ are available for all instantaneous variables and PT100 inputs’.


Page 42

Drag across the 2.R2.2 function block.


This time, the ‘Input type’ has been programmed for ‘Out Control’. If the measured temperature

drops below -5°C or exceeds 60°C, this alarm will activate.
