Indication
No connection with BMS
If there are no Heartbeat messages from the BMS controller over the CAN bus the following message will be output on the display:
Sound signals are not emitted in this case.
BMS initialization
If the connection with the BMS controller is established and the BMS is in the initialization mode (during the initialization the current sensor is calibrating and the BMS Logic boards searching is performed), the second line of the display will contain zero values of the voltage, current and temperature:
Sound signals are not emitted in this case.
- Battery discharging
If the battery is in the discharging mode (the current is zero or negative) and there are no errors, the first line of the display will contain the charge level and the second line will contain battery parameters: voltage, current and minimum/maximum temperature:
Note – Views with the minimum and maximum temperatures are changing every 2 seconds. To change them manually press the button on the device or an external button connected to the P6 header.
If the battery charge level is below the value set in the Low battery level signal (single beep) group, the device will emit a sound signal about the low battery charge level.
If the battery charge level is below the value set in the Battery discharged signal (three beeps) group, the device will emit three sound signals alarming that the battery is empty.
- Battery charging
The device emits a sound signal if the charger is connected to the battery. Duration of the signal is set by the Signal duration on charger connected parameter. The following message will be output to the display in this case:
The device emits two signals if the charger is disconnected from the battery. Duration of the signals is set by the Signal duration on charger disconnected parameter. The following message will be output to the display in this case:
If the battery is charging the following animation will appear on the display:
-
- Indication of errors
If there are errors selected by the Errors filter (see Display options group), names or codes of errors will be output to the display. In this case a loud sound signal is periodically emitted.
If the number of errors is greater than three, a list of errors will be output page by page. Turning pages will be performed automatically every 2 seconds. It is also available changing pages manually using the button on the device or an external button connected to the P6 header.
