Ks Hauptsignal (DB)

Signal-ID: 219 (hex: 0xDB)

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

Ks-multiple section signal + Zs1
Ks-multiple section signal + Zs7
Ks-main signal + Zs1
Ks-main signal + Zs7
Ks-distant signal

The combination signals can take on the function of the main signal, distant signal or a combined main and distant signal (multiple section signal).

The Z21 signal DECODER can also control additional signals and additional lights such as Zs1, Zs3, Zs3v, shortened braking path and distant signal repeater. In addition, depending on the signal design, either Zs7 or Sh1 can be presented.

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

With the usual DCC "Single accessory decoder packet format" (DCC Basic Accessory Command), only 4*4=16 signal aspects can be switched, see the columns "Trigger" and "Mode".Theoretically, however, a Ks signal can when fully developed present over 20 signal aspects. For this reason, restrictions must be made for the rare signal aspects with the combination "Ks2+Zs3v" as well as operational shutdowns.

If you wish to use the full scope of functions and really want to switch all possible signal aspects, then you can do this using a DCC control centre which commands the "DCC Extended Accessory Command". See also the column DCCext. The values for DCCext result on the Ks signal from the following system:

0, 65, 69 and 71 stand for Hp0 (red), Hp0+Sh1, Hp0+Zs1 and Hp0+Zs7
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)
Subtract 1 in order to switch on a speed limit Zs3 as well: 1, 5, 8 and 15 stand for Ks2+Zs3, Ks2+Zs3v+Zs3, Ks1+Zs3v+Zs3 and Ks1+Zs3
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"
