Battery Discharge Indicator (BDI)
e 1226BL controller can drive a BDI panel meter that displays the battery’s state-of-charge. e
battery must go through a full charge cycle before the BDI begins operating.
If the vehicle system uses a BDI, connect the BDI to the BDI Output pin (J3-5).
Note: For information on conguring the controller’s BDI output, see BDI Menu and Calibrating
the Battery Discharge Indicator (BDI) Output.
e following table describes the BDI output specications.
Specification Value
Output Voltage
0~5.0V. The voltage is linear to the BDI
percentage, with a 2% tolerance.
Load capacity 15mA
Maximum Voltage 105V
Maximum reverse voltage –1V
Circuitry Protection Fuses
To protect against accidental shorts, the following fuses are recommended:
• A low current fuse, appropriately sized for the maximum control circuit current draw, should
be connected in series with the B+ logic supply. See the control fuse in Figure 6.
• A power fuse, appropriately sized for the controller’s maximum rated current, should be
connected in series from the battery to the controller’s B+ terminal. is fuse will protect the
power system from external shorts.
Valve Driver or External Status LED Driver
Pin J3-2 can drive a valve contactor or an external status LED. When used for an external status LED,
the driver will output the controller status and any fault codes.
e External Status LED Enable parameter species whether pin J3-2 is used as a valve driver or
external status LED driver.
External Power Supply
e controller provides two output pins for external power supply, as described in the following table:
External Power

Pin
+5V J1-1
+14V J2-4
