External Status LED
The 1226 controller supports using an external status LED that allows the operator to see the
controller’s status. is LED always indicates whether the controller is powered on or o. e LED
will also provide fault information via the ash codes described in Table 33.
To congure the controller for an external status LED, do the following:
• Connect the LED to the pin for the driver you will use.
• Set the External Status LED Enable parameter to 1. See page 46.
• Set the External Status LED Driver to the number of the LED driver. See page 50.
If the vehicle system requires an external status LED, install the LED with the proper resistor in series.
e LED drivers are capable of a maximum current of 15mA. e recommended resistor—designed
to limit driver current to 15mA when active—is dependent upon the battery’s nominal voltage, as
described in Table 11.
Alternatively, an LED with a built-in resistor can be used; it should be rated for the battery’s nominal
voltage operation.
Horn
e 1226 controller has a dedicated horn driver that drives with either the low side or high side
method. e driver’s maximum current is 30mA.
To use a horn driver, do the following:
• Connect the horn to pin J3-2.
• If you are using a low side driver, it should take feed from the Coil Return pin (J3-10). For
an example, see Figure 6.
• Specify the driver type with the Horn menu’s Type parameter. See page 44.
Note: You can use the Horn menu to congure the horn to sound when the vehicle is traveling in
reverse. You can also congure the horn to sound audible fault codes.
