Fan speed and shaft speed alarms

The display monitors fan and shaft speeds. It shows configurable alarms for abnormal thresholds, with options to pause alerts temporarily and adjust settings from the Operator menu.
The display can monitor either one or two fans and one or two metering shafts. This is controlled by the drill configuration. A fan alarm has a low-speed and a high-speed configurable threshold. A metering shaft alarm has a low-speed alarm threshold with a configurable time delay before activation. You can configure the time delays from the Operator menu. If a fan and/or shaft speed goes above (or below) the thresholds, an alarm window replaces the tramline window and flashes red, then the display makes five alert sounds. Select to temporarily pause an alarm. The alarm display restarts after 30 seconds until the fan or shaft speed is back in the correct range.
