Warning

When the warning is triggered for event codes, such as 30,31,40,41,50,51,52 and 53, the HMI will pop-up the alarm screen. The green source LED blinks OFF or ON for event codes such as 54,55,70,71,72,73,74,75,76,77,78,79,80 and 81. The event code list and display method are shown in the below table.

The icon is displayed on the page to indicate an active warning.

If the warning is triggered, it will display the latest warning and previous alarms are overwritten on the HMI. The log will be recorded.

Perform the following procedure to check and clear the alarm:

Select the Set & Operate page and press OK.
Enter the password to open the Set & Operate page.
Select Operations sub-page.
Press Down button and select Warning Ack.
Click OK on the screen.

The warning will not inhibit the transfer functions for the below event codes:

SI Unbalance Warning

Event code: 50.
Type of event: Warning.
Default: Disable.
Description: If unbalance of voltage occurs over the drop-out rate of threshold (5% as default) when SI is connected, a warning will be raised.
Cause: Too many single-phase loads or poor quality of power supply environment.
Diagnosis and repair: Set the different value of imbalance rate or contact field service.

SII Unbalance Warning

Event code: 51.
Type of event: Warning.
Default: Disable.
Description: If unbalance of voltage occurs over the drop-out rate of threshold (5% as default) when SII is connected, a warning will be raised.
Cause: Too many single-phase loads or poor quality of power supply environment.
Diagnosis and repair: Set the different value of imbalance rate or contact field service.

Generator Invalid

Event code: 30.
Type of event: Warning.
Default: Always disable.
Description: The sudden loss of an alternate source will lead to a warning.
Cause: Genset is not connected well or some failure on Genset started
Diagnosis and repair: Contact field service.

Generator Start Failure

Event code: 31.
Type of event: Warning.
Default: Disable.
Description: After sending the Genset start signal, controller will wait a time T10 duration until Genset is ready.
- The ATSE will rise the Genset alarm, if Genset is not started within T10 timer is ended (if enabled).
- The ATSE shall reset the Genset alarm, when the A source is in range or when the N source is in range.
- The time delay is only available when there is external power.

Cause: Genset is not connected well or some failure on Genset started.
Diagnosis and repair: Contact field service.

On Load/Off Load Test Failure

Event code: 40, 41
Type of event: Warning.
Default: Always enabled.

Cause: Wrong connection of neutral or wrong settings.
Diagnosis and repair: Set the new neutral sequence or contact field service.

SI or SII Neutral Loss Warning

Event code: 54, 55
Type of event: Warning.
Default: Disabled.
