5 Operation
The available system operations are based on four different modes: normal mode, single Tx mode, debug mode, and simulation mode. These system modes enable the user to use, analyse, debug, and simulate actions that can be taken by the system. Password is needed to access the different programming menus. The system services might be interrupted by some menu operations.
ANormal Mode
When the system is in Normal Mode, some values can be changed without interrupting the system service. After changing a value in the menu fields, the new value will take effect right after the user gets back to the MAIN MENU. The Normal Mode is the normal system operation. Note: Entering the EVENT MENU will disable Event evaluation and reset their status — during that time, the system is out of service until the user goes back to the MAIN MENU.

Warning
Any actions taken in these menus reset the Event status.Note: Displays details in the following pages.
BSingle Tx Mode
The Single Tx Mode doesn’t prevent Event evaluation. By entering this mode, the user is able to analyse one sensor at a time. Only the displayed device is interrogated by the controller, thus has its information updated.
CDebug Mode
This mode is very helpful to evaluate the system, test the system operation without stopping any system services and calibrate the connected sensors. In fact, everything stays in operation except that no actions are taken by the Event. This way no relay is activated.
Note: If one of these modes is accessed, the system will automatically return to Normal Mode after 15 minutes.
DSimulation Mode
•The Simulation Mode deactivates information update from the network communication.
•This mode simulates the gas concentration over associated scale range for each sensor, one after the other.
•The alarm level (A, B, C) are evaluated in accordance to the gas concentration simulated.
•Events are evaluated and actions are taken.
•During the simulation, the controller is unaware of the current status of the network device.
•Simulation Mode can be stopped in the TEST MENU at any time.
Note: Simulation Mode can be combined with any of the three previous ones (i.e., Normal Mode, Single Tx Mode, or Debug Mode). No other combinations are possible.
