Hl-Signal (DR)

Signal-ID: 221 (hex: 0xDD)

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

Multiple section signal
Hl multiple section signal (DV 301)
Hl distant signal (DV 301)

Terminal assignment

1 - Red LED

Main red

2 - Green LED

Proceed with maximum speed (steady light) or 100 km/h (flashing light)

3 - Yellow LED

Expect stop (steady light), moderate speed (flashing light)

4 - Yellow LED

Speed limit from the signal location

5 - Yellow LED

Light strip (optional): valid speed from the signal location (60 km/h)

6 - Green LED

Light strip (optional): valid speed from the signal location (100 km/h)

7 - White LED

Ra12 (Sh1), Zs1

8 - White LED

Ra12 (Sh1)

With the usual "DCC Basic Accessory Command", only 4*4=16 signal aspects can be switched, see the columns "Trigger" and "Mode".Theoretically, however, an Hl signal can when fully developed present up to 19 signal aspects. For this reason, restrictions must be made for the signal aspects "Hp0+Zs1", "Hl9a" (proceed with 40 km/h, then with 40 or 60 km/h) and "Hl6a" (proceed with 40 km/h, then with 100 km/h). If necessary, however, these aspects can still be shown in the form of a makeshift solution if you can do without the yellow or green light strips on terminals 5 or 6 in the respective signal.

If, however, 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 from the following system:

0, 65 and 69 stand for "Stop", "Shunting signal" and "Substitution signal"
The following values stand for the next signal to be expected: 1="Expect stop", 4="40 or 60 km/h", 10="100 km/h" and 16="Maximum speed". This is sufficient in order for example to switch the distant signal.
In order to optionally display a speed limit at the location of the multiple section signal, you can add the following values: 32="40 km/h", 128="60 km/h" and 160="100 km/h" at the location.

Example:
10 = "100 km/h" at the next signal
128 = "60 km/h at the location"
10 + 128 = 138 ... is equivalent to Hl6b "Proceed with 60 km/h, then with 100 km/h", see also signal aspect "Hl6b" above.
