16.1.2 Functions 1, 4, 5, 6, 7, & 8
Press the number key on the numeric keypad that corresponds with
the function number you want turn on/off. The function will toggle
between on and off each time you press the number key.
The BELL 1 Key is used for function 1 and is labeled with a bell
icon to remind you that this is the preferred function key for bell
operation.
16.1.3 Function 2 (F2)
Press the HORN 2 Key on the numeric keypad. The HORN 2 Key
operates Function 2 and is labeled with a whistle icon to remind you
that this is the preferred function for whistle or horn operation. This
key is set up as a “non-latching key” so that if a horn or whistle
sound is installed in the loco, it will sound for as long as the key is
held down. This lets you vary the length of time that the horn or
whistle blows, just like the prototype.
If you want Function 2 to remain on:
1. Press and hold the HORN 2 Key.
2. Press and hold the EXIT Key.
3. Release the HORN 2 Key
4. Release the EXIT Key.
16.1.4 Function 3 (F3)
Press the COUPLER 3 Key on the numeric keypad. COUPLER 3
Key operates Function 3 and is labeled with a coupler icon to
remind you that this is the preferred function for coupler operation.
The DCS50 treats Function 3 is a normal on/off function unless you
set it up as a non-latching function like Function 2. This means
that F3 can be used either as a normal function or to control a func-
tion that requires a momentary activation like some couplers.
To set up Function 3 as a non-latching function, set the DCS50’s
Option Switch 6 to closed as follows:
1. Press the PROG Key. The display shows the last programming mode
used by the DCS50.
2. Press the SWITCH Key. The display shows the last switch used by
the DCS50.
3. Use the numeric KEY PAD to enter 006. This tells the system that
you want to change Option Switch 6, the OpSw that controls
whether F3 is latching or non-latching.
