Grade-Crossing Logic
Grade-Crossing Logic allows you to set up lighting
functions, the bell, and airhorn to automatically
simulate encountering grade crossings. Add a
value of 64 to enable Grade-Crossing Logic.
Turning on the long airhorn function (F2 by
default) or the grade-crossing signal function (F9
by default) will start the crossing hold timer
countdown and allow lighting effects to assume a
flashing state. Shown in Table F, flashing
Hyperlight effects will return to an on or off state
after the countdown ends. Practice activating
Grade-Crossing Logic as your locomotive
approaches a grade crossing. You can adjust the
crossing hold timer countdown from 0 to 15
seconds by entering a value from 0 to 15 into CV
60 (Grade-Crossing Hold Time).
To allow the bell to ring during the crossing hold timer countdown, enable the grade-crossing
bell in CV 122 (Bell Select). Refer to “Configuring Sound Effects” for more information about the
grade-crossing bell.
LED Compensation Mode
The brightness of an incandescent bulb is determined by voltage, whereas an LED’s brightness
is determined by current. LED Compensation Mode alters the method of sending current to the
LED to balance the LED and incandescent brightness levels. Add a value of 128 to enable LED
Compensation Mode for the corresponding lighting output.
Note
:
Enabling LED Compensation Mode will not change the output voltage. Resistors may still
be necessary depending on the board format.
Adjusting Lighting Output Settings
After configuring Hyperlight effects and features with CVs 49-54, adjust CV 57 (Forward
Direction Enable), CV 58 (Reverse Direction Enable), CV 59 (Hyperlight Flash Rate), CV 61
(Brightness Register 1), CV 62 (Brightness Register 2), CV 63 (Dimmer Level), and CV 64
(Master Brightness Register) to customize lighting output direction, the Hyperlight flash rate, and
brightness levels.
Enable Lighting Output Direction
CV 57 determines the lighting outputs active in the forward
direction, and CV 58 determines lighting outputs active in the
reverse direction. Table G shows values used to enable
lighting outputs for the forward and reverse directions. To
enable lighting outputs for the forward direction, add the
values of your preferred lighting outputs and enter the sum
into CV 57. To enable lighting outputs for the reverse
direction, add the values of your preferred lighting outputs
and enter the sum into CV 58.
The headlight is disabled in the reverse direction and the backup light is disabled for the forward
direction by default, i.e., CV 57 is set to 61 by default and CV 58 is set to 62 by default.
