Ks Vorsignal (DB)

Signal-ID: 220 (hex 0xDC)

Using this signal configuration, the following signals can for example be operated:

Ks distant signal with optional additional signal Zs3v

This signal configuration is similar to the "Ks main signal (DB)" with the Signal-ID 219 (0xDB), but is limited to the relevant distant signal aspects and features simplified assignment at the terminals.

The Z21 signal DECODER can also optionally control the additional signal and additional lights for Zs3v, shortened braking path and distant signal repeater.

Terminal assignment

1 - White LED

Additional light (optional) shortened braking path (“vBw”)

2 - Green LED

Signal light Ks1

3 - Yellow LED

Signal light Ks2

4 - Yellow LED

Zs3v distant speed display (optional)

5 - White LED

Additional light (optional) distant signal repeater (“Vwh”)

Expect stop + Distant speed display + Shortened braking path

This very rare signal combination can occur if for example a single speed display Zs3 is located between the location and the next main signal.
The braking path distance to the next main signal is shortened.

Additional light
Only the bottom white marker light is switched on.

With this signal configuration, rare signal aspects such as "Ks2+Zs3v" and operational shutdowns can also be switched with the standard

"DCC Basic Accessory Command".

However, it is also possible to switched the signal aspects - as for the "Ks main signal (DB)" with the signal-ID 219 (0xDB) - with the "DCC Extended Accessory Command", see also column DCCext.

The values for DCCext result on the Ks signal from the following system:

66, 67 as well as 68 stand for "complete dark switching", "only the top marker light" and "only the bottom marker light".
2, 6, 9 and 16 stand for Ks2 (yellow), Ks2+Zs3v (yellow with distant speed display), Ks1+Zs3v (green flashing with distant speed display) and Ks1 (green continuous light).
If applicable, add 32 to switch on the bottom white additional light for the distant signal repeater as well: 2+32=34 ... "Ks2 + distant signal repeater".
If applicable, add 128 to switch on the top white additional light for the shortened braking path as well: 2+128=130 ... "Ks2 + Shortened braking path".
