IRIS Radar Status Menu Mode Configuration
IRIS Mode is determined by the Radar Status Menu, that is, the name at the top of the menus. When IRIS first starts, the DEFAULT mode loads. During operation, you can change the mode using one of the following mechanisms:
- Manually in the Radar Status Menu by selecting .
- Automatically with a warning product. This is often used to switch between a surveillance mode and perhaps a volume scan or wind shear detection mode.
- Externally, forced by RCP. You c an configure RCP to either constantly force a mode (prohibiting manual or automatic mode changes), or trigger a mode change and then allow a manual or automatic mode change from the Radar Status Menu.
This example used is for redundant system operation of a wind shear detection system that has two operational modes called AERIAL (for general weather monitoring) and AIRPORT (for optimized for wind shear detection. The following table shows a summary of IRIS configuration.
| RCP02 Mode Number | Radar Status Menu (IRIS mode name) | TASK Schedule | Product Schedule | Output Schedule |
|---|---|---|---|---|
| 1 |
MAINTENANCE Mode entered when the system is intentionally disabled by either the hardware or software selector switches. It is recommended to blank the task schedule, clear all output assignments and generate no products. For safety, the servo power and radiate can be set to OFF in the Radar Status Menu. |
MAINTENANCE | MAINTENANCE | MAINTENANCE |
| 2 |
STANDBY Task scheduler is set to inactive (no task scheduled). For safety, the servo power and radiate can be set to OFF in the Radar Status Menu. |
STANDBY (inactive) | PRODUCT | OUTPUT |
| 3 |
AERIAL Configured for a long range surveillance scan and a volume scan for routine weather monitoring. |
AERIAL | PRODUCT | OUTPUT |
| 4 |
AIRPORT Optimized for wind shear detection. |
AIRPORT | PRODUCT | OUTPUT |
It is assumed that the same product schedule and output schedules are configured for all modes except the MAINTENANCE mode, that is, these schedules include all of the required products for all of the modes. It is possible to have different product and output schedules, but this increases the configuration maintenance.
| For the recommended redundant configuration, you need to have the system disabled by the hardware A/B switch or the A/B select in the Switching menu to configure IRIS modes. For normal redundant configuration of RCP, this forces IRIS into MAINTENANCE mode and then release IRIS to allow manual mode changes for configuration of the other IRIS modes. |
