Roco 10808 Z21 Detector

Important Information

• In the event of the track voltage failing (e.g. short circuit or emergency stop), the Z21 detector is no longer supplied so that feedbacks are therefore not possible.

• The Z21 detector 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 to be positioned close to strong sources of heat such as heating radiators or places where there is direct sunlight.

• As the Z21 detector 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 coming into contact with metal objects or live conductors (track voltage) under all
  circumstances!

• The supplying booster or the control centre are to provide a maximum of 3A at the track output as each of the inputs could be overloaded otherwise. The Z21 control centres and Z21 boosters from ROCO meet this
  requirement.

Intended Use and Function

A complete or partial automation of your system makes it absolutely necessary that you install an efficient feedback system.
The Z21 detector 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.
Should you use the Z21 detector with the CAN connection, you can read the locomotive addresses on the occupied track sections and determine the rerailing direction by using the RailCom®.
You will find more usage and configuration information on the www.z21.eu website (10808 – Z21 Detector). As the Z21 detector 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 has 8 detector inputs that are designed in the form of a current sensor with a Rail-Com® detector. The current limit per section is 3A.
  As the data cables (CAN and R-BUS) are galvanically separated from the track voltage, there is practi-cally no risk of a short circuit.
  The Z21 detector 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 detect an occupied message, this has to exist for a minimum duration of 160 ms. It is only forwarded as a valid message then.

• Deactivation delay
  Should an occupied track no longer be occupied, the Z21 detector forwards the detected vacant messa-ge after a delay of 1160 ms.
  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 centre when the delay duration is no longer interrupted by a short occupied message.
  This avoids incorrect occupied messages in the event of there being a poor train-track contact.

Mounting the Z21 Detector

Mount the Z21 detector in a visible place with adequate ventilation so that the waste heat can dissipate. Under no circumstances is the Z21 detector to be positioned close to strong sources of heat such as hea-ting radiators or places where there is direct sunlight. This Z21 detector has exclusively been designed for use in dry interiors. The Z21 detector is therefore not to be operated in environments that are subjected to great temperature and air humidity fluctuations.

Tip: Mount the Z21 detector using half round head screws, e.g. 3 x 30 mm.

Z21 Connecting the Z21 Detector to the Track System:

Switching tracks or dry reed contact
The simplest form of the message feedback 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 3.3k ohm 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.

Note: The ROCO articles 42518, 42605, 61117 and 61193 contain electronic components inside the connector for protecting the reed-contact, which can lead to unwanted occupancy messages at the detector input. In such a case, increase the setting for the occupancy threshold in the detector to 4 to 5 mA, see also section Confi guration using the Z21 Maintenance Tool.

Current sensor
With this method, the feedback devices measure the current that is fl owing through the track section. This results in each of the current consumers generating an occupied message for this section.

2-conductor track
For the power supply, connect the inputs P and N to the corresponding booster outputs and connect the 8 feedback terminals to the corresponding feedback sections.

Note: The feedback sections are to be separated from the system from both sides.
Please also ensure that the se-paration consistently takes place on the correct voltage side.
Short circuiting could otherwise occur when the separation points are crossed.

3-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 feedback section to one of the 8 feedback terminals.

Note: It is also the case here that both sides of the feedback 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.

Z21 Connecting the Z21 Detector to the Control Centre

The detector can be connected to the control centre in two ways:

• via the CAN interface on the black Z21
• via the R-BUS interface on all of the Z21 control centres and the multiZENTRALEpro

Interfaces and their possibilities

Connection via R-BUS

Connection via CAN-BUS

NOTE: Please note that only the enclosed connecting cables are to be used as these have a sufficiently large cross-section that ensure an optimal current supply.

Configuration

Configuration using push-buttons
Connect the Z21 detector to your chosen bus system and provide the track inputs P and N on the Z21 detector with the track voltage from the control centre.
The blue status LED flashes briefly and only remains illuminated when it is connected to the CAN or the R-BUS respectively.
Press the programming button on the Z21 detector 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 after the white program LED has stopped flashing.

Confi guration using the Z21 maintenance tool

Note: only possible via the CAN-BUS and with at least maintenance version 1.12 and Z21 fi rmware 1.30.

Connect the Z21 detector to the Z21 via the CAN-BUS and provide the track inputs P and N on the Z21 detector with the track voltage from the control centre.
The Z21 detector is confi gured in the “Z21 Maintenance Tool“ software as follows:
After you have connected the Z21 detector correctly and have clicked on the “Status anfordern” (Request status) button on the CAN tab, an own panel is inserted for each of the detected CAN modules. The NetID is a unique identifi er of the CAN module
You can now see which track sections are occupied, in addition to the locomotive address and the rerail direction. (Note: only works with locomotives that are RailCom® -compatible).

The module address can be set and fi rmware updates carried out under “Setup“.
You can alter the occupied threshold and the delay durations for an occupied message or a vacant messa-ge respectively. The Z21 detector can be used as a RailCom® local detector if the function “RailCom® Ka-nal 2 Daten an die Zentrale weiterleiten“ (Forward Channel 2 data to the control centre) is activated. This means that the POM reading also functions in sections in which a Z21 light booster is used, for example

The Z21 Maintenance Tool also includes the possibility of an R-BUS and LocoNet emulation under the “CAN“ tab. These makes it possible for you to use the Z21 detector in existing PC control systems without this having the be expanded fi rst. The Z21 detector is confi gured in the PC control system or in the Z21-App as a ROCO 10787 or as a LocoNet occupied detector.

Note: Please do not forget that each emulation generates additional occupied feedbacks so that the possible Z21 Ethernet interface bandwidths are reduced. You should therefore only activate the emulation you require.
