Menu Structure
The Gasguard IS Programmable Controller has two levels of use:
1. Main Menu (user-read only)
2. View and Modify (programmable password protected)
The first level, which is read only, enables the user to view all current settings and real time data without affecting the
configuration of the controller.
The second level has the features of the first plus the ability to view and modify the calibration and configuration of
the Gasguard Controller.
The default screen is the Monitoring screen. This allows the user to view the actual monitored gas levels; and will
display alarms if activated. To view current settings the user must operate the keypad.
3.1 Key Pad Functions in Main Menu
The facia of the Gasguard IS Controller has a two line 16-character Liquid Crystal Display (LCD), Status LED’s and a
tactile keypad.
The layout of the display structure is graphically illustrated in Section 5 of this manual – ‘Flowcharts’.
Navigation of the menu is performed by pressing the arrow keys on the keypad.
The display level is changed with the Up and Down arrow keys, and the display position is changed with the Left and
Right arrow keys.
The Up arrow key and Down arrow key enable the user to scroll through the menu.
The Right arrow key allows the user to view more detailed information about channels, zones, relays, alarms and
outputs.
The Left arrow key allows the user to escape from the present screen.
The Alarm Reset function is carried out by holding the Left arrow key for 5 seconds. Any alarm that is below the
preset threshold will be reset (only if the left button reset is enabled in the configuration settings).
