Objective

● SRC5,6 & 10 KVA Common Issues

● BR1000G-IN and BR1500G-IN Fault Codes and Common Issues

● NPF Discussion

● Defective Service Tag

● DOA Failures


SRC5000, 6000 and 10000UXI Failures

● We have noticed the following common issue in these models:

● 010 DC Bus OverV● 016 DC Bus Low● 008 Charger Fail

●Let us look at these issue in detail and corrective action for the same.


010 DC Bus OverV

●The following Environmental issues can cause this fault:1. Inductive load2. Inverter is short with utility (by external manual bypass

switch).3. Generator Abnormal frequency and voltage input to the UPS

●The following UPS Internal fault:1. Wrong feedback circuit for bus voltage

2. Wrong detection circuit for bus voltage


Contd.,●Troubleshooting:

● If you notice the above mentioned fault in the field, please do the following:

●Check the load and ensure that the load is normal ● Check the Generator output frequency and voltage if available, and ensure that the Genset frequency is between 47-53 Hz and ensure that the frequency is not varying abnormally

● If the “010 DC Bus OverV “ fault clears after your restart the UPS, then upgrade the UPS firmware. Please contact your Regional APC tech specialist for the same.


016 DC Bus Low

● The fault is generated due to the following reasons:● 1. PFC/DC-DC circuit is fail● 2. Feedback circuit for BUS voltage is fail

● Restart the UPS and see if the fault clears. If the fault does not clear, then replace the unit and mention the fault code on the defective service tag.


008 Charger Fail

●This fault is generated due to Charger circuit failure.

● Please ensure that there is no third party external charger is connected to the unit. If it is connected, remove it and restart to see if the unit is working without fault.

● If the fault does not clear, then it indicates that there is an issue with the charger circuit.


Quick Quiz

● SRC6000UXI is connected to 16 numbers of 12 Vdc, 65 AH batteries.

● What is the total external battery AH that needs to be set on the SRC6000UXI display?


BR1000G-IN and BR1500G-IN Fault Codes and Common Issues

● APC is noticing a lot of NPFs in these models. We have provided three refresher training on these models. We hope all of our FSEs are familiar with these models. If you have any doubts, please clarify all your queries regarding these products.

● Let us look at the common fault codes of these models.


NEW Master and Controlled outlets

●To conserve electricity, when the device connected to Master Outlet goes into Sleep or Standby mode, or turns Off, the Controlled by Master device(s) will shut down as well, saving electricity.

●Connect a master device, such as a desktop computer or audio/visual receiver to the Master outlet. Connect peripheral devices such as a printer, speakers, or a scanner to the Controlled by Master outlets.

Configuration

Power-Saving Master & Controlled outlets:

Configure Back-UPS to recognize a Master device and Controlled peripherals.

Enable the Power-Saving feature: ● Press and hold MUTE and DISPLAY simultaneously for two seconds.● Unit will beep to indicate that the feature is enabled.

Disable the Power-Saving feature: ● Press and hold MUTE and DISPLAY simultaneously for two seconds● Unit will beep to indicate that the feature is disabled.

Setting the Threshold:

1. Ensure your computer is plugged into the Master outlet.

2. Put your computer into Sleep or Standby mode, or turn it OFF.

3. Press DISPLAY and MUTE simultaneously for six seconds, until the leaf icon flashes three times and the unit beeps three times.

4. Back-UPS will now recognize the threshold level of the Master device and save it as the new threshold setting.


Configuration-Power Saving DisplayThe display interface can be configured to be continuously illuminated, or to

save energy, it can be configured to clear out after a period of inactivity.

1. Full Time Mode: Press and hold DISPLAY for two seconds. The display will illuminate and the Back-UPS will beep to confirm the Full-Time mode.

2. Power-Saving Mode: Press and hold DISPLAY for two seconds. The display will go dark and the Back-UPS will beep to confirm the Power-Saving mode. While in Power-Saving Mode, the display will illuminate if a button is pressed, it then goes dark after 60 seconds of no activity.


ConfigurationAdjusting UPS sensitivity:

Adjust sensitivity of the UPS to control when it will switch to battery power.

1. Ensure the unit is connected to utility power, but is OFF.

2. Press and hold the POWER button for six seconds.

3. LOAD CAPACITY bar will flash on and off, indicating that the unit is in programming mode.

4. Press POWER again to rotate through the menu options.

5. Stop at selected sensitivity. The unit will beep to confirm the selection.

NPF Discussion

● Smart UPS NPFs are a big concern for the Company. We are incurring huge cost on Smart UPSs which are becoming NPFs at our repair center.

● Please discuss any issues with APC regional tech specialist and clarify the issue before replacing any units which are more than 5 KVA.

● Please ensure to fill the Defective Service Tags with actual fault so that NPFs can be avoided with the respect the fault code.


DOA Failures

● We request you to get an email approval from your RTS if you notice any DOA failures of above 5 KVA UPSs in the field.

● You can discuss the issue over the phone with RTS, and get an email approval from RTS before replacing the unit.


Burnt cases-Process to Follow ● Your FSE needs to contact APC Regional Tech Specialist for any burnt

cases which need approval for warranty replacement. ● Collect all the required details(but not limited to)such as FSR, Any Site

abnormalities, Pictures of the Site, Pictures of the damaged UPS and the following Excel file details.

● Send an email to your APC Regional Tech Specialist with your justification along with all the above-mentioned details if the case requires approval for warranty replacement

● Email Subject line should be "<Service Request Number>_<CITY OF THE CUSTOMER LOCATION>_<ASP CODE WHO ATTENDED THE CALL>"

● -This email subject line will help us to easily navigate the cases. -Note: Please keep your region's Service Manager and Call Coordinator email addresses in CC while sending an email to the regional tech specialist. -Please make sure that the Customers are informed about the developments during approval process. We will review the case and contact you in case if we require any additional details to assess the failure.
