Important information
- In the event of the track voltage failing (e.g. short circuit or emergency stop), the Z21®- detector X16 is no longer supplied so feedbacks are therefore not possible.
- The Z21®- detector X16 is only suitable for use with electric model railway systems. The model railway system should also never be operated unsupervised.
- Under no circumstances is the Z21®- detector X16 to be positioned close to strong sources of heat such as heating radiators or places where there is direct sunlight.
- As the Z21®- detector X16 has exclusively been designed for use in dry interiors, it is not to be operated in environments that are subjected to great temperature and air humidity fluctuations.
- Prevent the Z21®- detector X16 from coming into contact with metal objects or live conductors (track voltage) under all circumstances!
- The supplying booster or the control center is to provide a maximum of 3A at the track output as each of the inputs could be overloaded otherwise. The Z21® control centers and Z21® boosters from ROCO meet this requirement.
Brief Instructions
NOTE: The green “Detect” LED indicates a change in one of the track sections by briefly y flashing, i.e. changes may also have occurred in several track sections at the same time which is not displayed separately.
Programming button
- Pressing for 1 second until max. 2 seconds: Configuration starts and white “Program” LED flashes
- Switch solenoid (e.g. turnout command) to the desired address
- The address is taken over by the Z21®- Detector X16
- If no entry is made, the programming mode is automatically exited after 60 seconds
- really excited after 60 seconds
Purpose of Use and Function
Complete or partial automation of your system makes it absolutely necessary
that you install an efficient feedback system.
The Z21®- Detector X16 provides you with information on the status of defined
track sections. This is especially useful if parts of your system are not
visible (e.g. staging yards) or if you want to have the occupied status of the
tracks displayed on your automation software or on the signal box of your Z21®
app. You will find more usage and configuration information on the www.z21.eu
website (10819 – Z21®- Detector X16). As the Z21®- detector X16 is permanently
provided with software-based function enhancements, you can always obtain the
latest information from the Z21® homepage.
Properties
-
Electrical properties
The Z21®- Detector X16 has 16 detector inputs that are designed in the form of a current sensor. The current limit per section is 3A. -
As the data cables (R-BUS) are galvanically separated from the track voltage, there is practically no risk of a short circuit.
-
The Z21®- Detector X16 only provides information on the occupied status of the track after a certain delay in order to avoid incorrect occupied messages being issued.
-
Activation delay
Should the Z21®- detector X16 detect an occupied message, this has to exist for a minimum duration of 10ms. It is only forwarded as a valid message then. -
Deactivation delay
Should an occupied track no longer be occupied, the Z21®- detector X16 forwards the detected vacant message after a delay of 260ms.
Should an occupied signal be transmitted again during the delay, this is not reported and the delay period recommences from the beginning. The “vacant status” is only forwarded to the control center when the delay duration is no longer interrupted by a short occupied message. This avoids incorrect occupied messages in the event of there being poor train-track contact.
Mounting the Z21®- Detector X16
Mount the Z21®- detector X16 in a visible place with adequate ventilation so
that the waste heat can dissipate. Under no circumstances is the Z21®-
detector X16 to be positioned close to strong sources of heat such as heating
radiators or places where there is direct sunlight. This Z21®- detector X16
has exclusively been designed for use in dry interiors. The Z21®- detector X16
is therefore not to be operated in environments that are subjected to great
temperature and air humidity fluctuations.Mount the Z21®- detector X16 using
half-round head screws, e.g. 3 x 30 mm.
Z21® Connecting the Z21®- Detector X16 to the Track System
Switching tracks or dry reed contact
The simplest form of the occupied detector is the use of dry reed contacts or
switching tracks that are earth-switched. A generation of an occupied message
is only possible if a 2,2kohm resistor (not included) is activated between the
detector input and the switching element. Should the resistance be too low,
the track voltages is burdened unnecessarily or the module or resistance
respectively are damaged.
Current sensor
With this method, the feedback devices measure the current that is flowing
through the track section. This results in each of the current consumers
generating an occupied message for this section.
conductor track
For the power supply, connect the inputs P and N to the corresponding booster
outputs and connect the 16 occupied detector terminals to the corresponding
occupied detector sections.
NOTE: The occupied detector sections are to be separated from the system
from both sides. Please also ensure that the separation consistently takes
place on the correct voltage side. Short-circuiting could otherwise occur when
the separation points are crossed.
conductor track
For the power supply, connect the inputs P and N to the corresponding booster
outputs. Separate both sides of the neutral conductor and connect the
resulting occupied detector section to one of the 16 occupied detector
terminals.
Note: It is also the case here that both sides of the occupied detector
sections are to be separated from the system. Please also ensure that the
separation consistently takes place at the neutral conductor. Short-circuiting
could otherwise occur when the separation points are
crossed.
Connect Z21®- Detector X16 to the control panel
You can connect the Z21®- Detector X16 via the R-BUS interface on all Z21®
control panels and the multi-ZENTRALEpro.
Connection via R-BUS
Configuration
NOTE: The module address assignment for the occupancy detector must not create “address gaps”, i.e. the individual module addresses must be assigned in consecutive numbering. It should also be noted that a Z21®- Detector X16 uses two consecutive addresses, as one address is needed per 8 occupancy detection inputs. When assigning addresses, only the first of these two mod- ule addresses should be assigned, the second and immediately the following address is determined independently by the occupancy detector.

inputs. When assigning addresses, only the first of these two module addresses
should be assigned, the second and immediately the following address is
determined independently by the occupancy detector.
Example: If no occupancy detector module address has yet been assigned,
then the first occupancy detector receives the address “1”, which leads to an
internal assignment of the two module addresses “1” and “2”. After that, by
assigning the address “3” to the next occupancy detector, the module address
pair “3” and “4” can be assigned.
Configuration via button
Connect the Z21®- Detector X16 to the R-BUS and supply the track voltage of
the control panel to the track inputs P and N of the Z21®- Detector X16. The
blue “Status” LED flashes briefly and does not light up permanently until you
have connected the Z21®- Detector X16 to the R-BUS. Press the programming
button on the Z21®- detector X16 for at least 1 second; the white program LED
starts to flash. Activate a magnet article with the address of your choice
within the next minute. The magnet article can be activated using the Z21® App
or another input device such as the multiMAUS. The address has been accepted
by the Z21®- detector X16 after the white program LED has stopped flashing.
Configuration via pseudo CV address
The Z21®- Detector X16 can also be configured using POM programming commands
if it is in configuration mode. The POM programming (“Programming on Main“ =
programming on the main track) normally serves to enable the programming of
the locomotive decoder to be carried out at the main track. The Z21®- Detector
X16 can process these POM programming commands when it is in configuration
mode – and only then – as long as these are directed at the “locomotive
address” 9819. Should you coincidentally have a locomotive with this address,
please remove it from the track beforehand if necessary.TIP: Memory aid:
Article number 10819 pseudo “loco address” 9819To then configure the Z21®-
Detector X16 using POM programming commands for loco decoders as well, proceed
as follows:
- Connect the Z21®- Detector X16 to the Z21® via the R-BUS and provide the track inputs P and N on Z21®- Detector X16 with the track voltage from the control center.
- If you use the Z21 App or the Z21 Maintenance Tool to configure the Z21®- Detector X16, you can ignore this step. However, if you want to use a WLANMAUS or multiMAUS to configure the Z21®- Detector X16, then follow these steps:
- SHIFT+MENU PROGRAM MODE POM OK STOP
- SHIFT+MENU LOCO MODE ADRESS OK STOP
- SHIFT+OK numbers 9 8 1 9 OK
- SHIFT+MENU PROGRAM CV MODIFICATION OK
- Enter the desired CV number (see table below) OK
- Now ignore the message “ERR 2” if necessary, because the CVs cannot be read.
- Enter the desired CV value, but wait until step 4 before pressing the OK button to actually write the value (see point 4 below).
- Put the Z21®- Detector X16 into configuration mode by pressing and holding the programming button on the Z21®- Detector X16 for at least 1 second (but no more than 2 seconds). After that, the white LED flashes for a maximum of one minute to show that the module is waiting for CV programming. The Z21®- Detector X16 is now in “configuration mode”.
- You can now configure the Z21®- Detector X16 by writing a CV variable via POM to the pseudo-“loco-motive address” 9819 with an input device of your choice.
- As soon as the POM write command to a valid CV has been understood by the Z21® Detector X16, the new value is adopted, and the configuration mode is automatically exited. The white LED goes out and the blue LED signals normal operation. The CVs can only be written, not read.
CVs for pseudo CV programming
| CV | Description | Note | Factory setting |
|---|---|---|---|
| 99 | Module address | 0 = adress 1 |
1…20 = adress 1…20,
21…255 = invalid (address not being changed)
| 1 (adress 1)
100| Current thresh- old| 0 = 0,5 mA, 1 = 1mA,
2 = 2mA, …, 70 = 70mA, 71…255 = 70mA
| 4 (4mA)
101| Response time| 0 = 10ms, 1 = 10ms, 2 = 20ms, …, 16 =
160ms, 17…255 = 160ms
| 1 (10ms)
102| Fall time| 0…255 = 0…2550ms| 10 (100ms)
Reset to factory settings
A factory reset is performed by pressing the programming button for 8 seconds.
1 second after the button has been pressed, the white LED starts flashing and
indicates the readiness to receive a CV. After 8 seconds the green LED will
light up and the factory settings will be restored. The programming button
should now be released within 1 second to avoid switching back to programming
mode.
R-BUS status via Z21® Maintenance Tool
If you have connected the Z21®- Detector X16 correctly and if you have
connected the occupancy detector sections to be monitored with one of the 16
occupancy detection terminals, then you can use the configuration software
“Z21® Maintenance Tool” in the R-BUS tab in the R-BUS status section to verify
the current occupancy status or see which track sections are
occupied.
