¶ Alerts and Notifications
E-Drive provides varying notifications and alerts to indicate current and historical system status.
Alerts vary in severity, from indication of minor issues that may not impact operation of the E-Drive system, through to indication of critical errors that prohibit system operation. Critical alerts are shown on-screen and are generally accessible as follows:
- Press the alert triangle located at the top of the E-Drive screen
- Press the flashing PAUSED icon when visible (for power inhibit notifications)
- Choosing the Alert page which is available on the nav station touchscreen screen menu.
Issues vary from GREEN (low severity) through to RED (high severity). If multiple alerts are present, the alert icon at the top of the screen changes colour to indicate the highest severity present.
¶ On-Screen Alert Notifications
On-screen notifications appear as shown in the following example; each notification is described in the ensuing table. These notifications can be dismissed, but will re-appear after 5 seconds until the condition has been resolved.
| On-screen Notification | Action(s) Required |
|---|---|
| System initialising...DO NOT START ENGINE | The system requires a short time to initialise after the ignition is switched on. Wait for this prompt to disappear before starting the engine! |
| Stop the engine and shift to neutral to initialise the system |
|
| Switch off the ignition and switch on again to initialise the system |
|
| Drive mode is paused. Tap for more info. | Press the notification to learn why Drive Mode is paused. |
| Select neutral to enable throttle | Move the throttle into the neutral position |
| The E-Drive motor does not operate in neutral | Deselect the throttle neutral switch, then move the throttle into gear. |
| An update is being applied, please wait ... | Wait for this dialog to disappear BEFORE starting the engine |
The following notifications may also appear when appropriate; the notification persists for five seconds.
| On-screen Notification | Action(s) Required |
|---|---|
| System will exit drive mode shortly | None. |
| System automatically switched to Standby due to inactivity | None. |
¶ Power Inhibit Notifications
If a condition prohibits generation or drive, a flashing Paused button is shown on the E-Drive screen to indicate E-Drive operation is inhibited. The following table provides a list of all conditions that can cause a power inhibit notification.
| Power Inhibit Notification | Description |
|---|---|
| Batteries Offline | All detected battery sensors report battery contactors are open resulting in a battery capacity of zero. |
| BMS (IO) | The system detected a stop charge/discharge signal from the physical inputs to the PCU. |
| BMS Stop Charge | The BMS indicates battery charging is currently prohibited. |
| BMS Stop Discharge | The BMS indicates battery discharging is currently prohibited. |
| Data Missing | Information necessary for safe operation of the system is unavailable or out of specification; review the Alerts screen for additional information. |
| Diagnostic Mode Active | Operation is limited because the system is in diagnostic mode. |
| Engine Warming Up | The engine temperature is below the configured by user settings. |
| Ignition OFF | The engine ignition (for the specified hull) needs to be powered on for the system to operate. |
| Manoeuver | Throttle changes indicate manoeuvring is in progress (only applicable when generating). |
| Motor Disabled | The motor controller is not able to function correctly; review the Alerts screen for additional information. |
| RPM High | The engine RPM is too high for the system to operate. In some systems, the E-Drive motor may be unable to generate useful power over the entire engine RPM range. |
| RPM Low | The engine RPM is too low for the system to generate power. This notification shows if the engine is not running, or if the engine RPM is below the minimum allowed RPM to generate power (which may be above the engine idle speed). |
| SoC Above Threshold | The battery state of charge is above the configured maximum charge limit (see the Controls screen; only applicable when generating) |
| SoC Below Threshold | The battery state of charge is below the configured minimum discharge limit (see the Controls screen; only applicable when driving). |
| System Error | One or more alerts prevent system operation; review the Alerts screen for additional information. |
| Temp. too High | One or more temperature sensors indicate the system is operating above a safe operating temperature limit. |
| Temp. too Low | One or more temperature sensors indicate the system is operating below a safe operating temperature limit. |
| Voltage too High | The voltage measured by the motor controller is above the maximum allowed threshold. |
| Voltage too Low | The voltage measured by the motor controller is below the minimum allowed threshold. |
