Main Line Voltage: 208 VAC
Main Line Voltage: 240 VAC
Main Line Voltage: 480 VAC
Testing Procedure
WARNING
DO NOT TOUCH THE BOARD WHILE THE MAIN POWER IS ON OR THE BLD IS IN OPERATION.
Pre-Test Requirements
Before powering up the BLD, perform the following checks
- Verify continuity between the following points
- ST1 to GND
- ST3 to GND
- ST4 to GND.
NOTE: There should be no continuity (no beep).
Test Procedure
Follow these steps to test the BLD
- Turn on the main line power.
- Set the battery switch to the ON position.
- Observe the Power, HB, Charge, and Fault LEDs. All should illuminate initially.
- Wait for 10 seconds; the Fault LED should turn off. If it does not turn off, press the reset button.
- Turn off the battery switch.
- Measure the DC voltage between ST2 and ST6 while pressing the reset switch. The reading should be between 28 – 32 VDC.
NOTE: If the voltage falls outside the range, turn OFF the battery disconnect switch and adjust the charging potentiometer to 31 – 32 VDC while keeping the reset switch pressed. - Once the voltage is confirmed, reverse the previous steps.
- Turn off the main line. Within three seconds, the BLD should activate if IN1 and 024 are jumped (NC).
- Confirm that the D11, HB, Power, and O2 LEDs are on.
NOTE: The O1 LED should remain off. If it turns on, the BLD has detected a fault. - During the test, adjust the AC output potentiometer to match the main line AC voltage. Measure the AC voltage on T3 and T6 of the BLD connector.
NOTE: The maximum AC output voltage is 240 VAC for both 240 VAC and 480 VAC main lines. - During the rescue operation, measure the battery DC voltage between ST1 and ST2. The voltage should decrease slowly under load and should not drop rapidly.
NOTE I: If the battery voltage decreases rapidly, the battery may lack sufficient charge capacity and require charging or replacement.
NOTE II: If the battery voltage falls to 19 VDC during rescue, the BLD will automatically turn off due to low voltage. - Once the rescue operation is completed, the battery will remain in idle mode for 10 minutes before the battery power turns off to preserve voltage. The Fault LED will then continue to blink every 300ms.
- The O1 LED may remain on even after the main line power is restored. This behavior is consistent with the Fault LED functionality. For example, if a Low Battery condition is detected while the main line power is on, both the Fault and O1 LEDs will illuminate and remain solid.
- When the BLD detects mainline power, it will switch back to normal operation.
NOTE: The D11 and O2 LEDs will turn off, while the Power, Charge, and HB LEDs remain on

Troubleshooting Tips
Perform the following checks if the BLD does not power on when the main line is disconnected:
- Check that the BLD disconnect switch is in the ON position (SW1 and SW2 should show a short on the battery connector).
- Check the continuity between O24 & IN1.
- BAT+ and BAT- should measure 26 – 28 VDC for fully charged batteries with the battery connector connected to the board.
- T3 and T6 should measure the same as the main line voltage.
- Verify that there is 120 VAC between terminals 120 and N for battery charging (charging will occur regardless of the BLD disconnect switch position) and that there is 28 – 32 VDC while the reset button is pressed.
- Check that the 40A fuse is not blown.
- Ensure proper incoming main line voltage.
- Verify proper outgoing wiring to the control transformer.
- Check for 24 VDC from the controller at terminal COM.
- Ensure correct battery connections.
- Monitor the flashing red LED code on the SR-3081H1 board
The table below lists and describes the different types of faults that may be encountered.
| Fault Type | Blink Cycle | Board Type | Description |
| Low Battery | Solid | BLDh | Triggered when the battery voltage falls below the low voltage threshold while not outputting. |
| AC Out Fault Input | Solid | BLDh | Activated when the AC Out Fault LED is off while the ERD is outputting. |
| Battery Test Fail | 900ms | BLDh | Triggered when the battery voltage difference across 20 samples exceeds 1V, indicating a faulty battery. This test runs every 24 hours or when DIP 3 is turned on while not outputting. |
| Rescue Timeout | 300ms | BLDh | Triggered when the rescue power (outputting state) reaches the ten-minute timeout. The timer resets when the system reboots or mainline power is restored. |
Disposal
Dispose of used batteries according to local regulations.
CAUTION: Do not dispose of batteries in a fire, as they may explode.
