1 General

1.1 On this document

This document describes the installation of the IRMA passenger counting system IRMA MATRIX

(sensors and IRMA gateway) with CAN cabling as well as the connection to the on-board

computer.

MATRIX sensors are designed for installation above passage areas. They can be mounted in the

upper part of door trims (coves

1

) either flush countersunk or on the surface (sensor versions

DIST500-F in the flush mount version and DIST500-A in the surface mount version).

The connection of the MATRIX sensors to the power supply and the CAN BUS will be made with

specially developed connectors which are available in different versions with different

functionalities and properties. For an overview see section 12.1.2 on p. 64.

The IRMA gateway converts the door statuses provided by the door contacts into control signals

compatible with a CAN BUS for switching the sensors and thus the counting process of the

respective doors on and off.

The CAN signal is adapted to different software and hardware components such as IBIS, RS485.2,

J1708, switching outputs, RS232, thanks to the use of different IRMA gateway versions.

If the counting system is operated without an IRMA gateway, the control signals for starting and

stopping the counting operation at each door are sent by the on-board computer, see e.g. Fig. 48,

p. 73.

For installation of the system please follow the individual operations described in the document.

Items or steps not applicable or already clarified may be skipped. For more detailed information

on the components referred to in this document please see the data sheets of the individual

components and the "M12 components for IRMA sensors on the CAN BUS" catalogue on our

website: https://www.irisgmbh.de/en/technical-documents/irma-matrix/

2 Important information when working with IRMA

MATRIX sensors

IRMA MATRIX sensors must only be installed by qualified expert staff trained by iris-GmbH

who observe the pertinent regulations and the installation manual.

2.1.1 New service software version required

Before starting the configuration of the IRMA MATRIX sensors, perform an update of the

"DIST500-Configuration Tool" service software to version "3.9.6.187" or higher. For more

detailed information on the software update see section 8.2.1 on p. 47.

2.1.2 Firmware

Important note:

Please bear the following in mind for firmware updates via an on-board computer!

Firmware versions having "1" as the first Fig. of the version designation must not be

installed any more.

The sensor firmware is continuously developed in order to keep up with technological

progress. As downward compatibility with the predecessor version is ensured from

firmware versions with "2" as the first Fig. on, different firmware versions in different

deliveries are by no means a functional restriction. The latest firmware version is: D5FC -

DIST500_Application_2.1.312.6797 - CE_CF_D0_D1_D4_D5.d5fc.

If a consistent firmware version is to be ensured for one order comprising several

deliveries, please indicate this requirement when placing your order.

2.1.3 Comparison of old and new counting firmware

The new firmware file

• D5FC-DIST500_Application_2.1.312.6797-CE_CF_D0_D1_D4_D5

added new parameters to the “Ethernet” and “Installation” tabs.

In the old firmware

• D5FC-DIST500_Application_2.0.0.5072 Single Count Category-

3521_CE_CF_D0_D1_D4_D5

In all considerations with regard to installation positions and orientation, it is assumed

that the observer is inside the vehicle.

these new parameters are visible, but greyed out and disabled.

The following Fig.s show the differences between the old and the new firmware:

Fig. 1: Comparison - DHCP deactivated in old counting firmware

Fig. 2: Comparison - deactivated buttons under "Installation"

3 Preparation of the installation

Careful preparation is required for successful and trouble-free installation of the IRMA

MATRIX passenger counting system. As the type of installation depends on the individual

conditions in the vehicle entrance area, the installation conditions must be checked in

preparation of the installation. The options for power supply and the connection to the on-

board computer (on-board computer/unit) of the vehicle must be clarified before the

installation starts.

Under “Ethernet” the DHCP function

is visible, but cannot be selected.

DHCP is active only in the new

firmware version.

Under “Installation” in the “Installation

parameters” range the following new

counting parameters are disabled:

• “Height of Entrance Level to Door”,

• “Left / Right Wall Distance”

• “Left / Right Opening Angle”

3.1 Vehicle data sheet

iris-GmbH offers a vehicle data sheet for vehicles which are to be equipped with the IRMA

passenger counting system. This data sheet serves to collect the main installation

conditions. Based on the information from the vehicle data sheet we can properly plan

your project in advance, thus helping you select the optimal components for your vehicle.

For a download of the vehicle data sheet please refer to our website

https://www.irisgmbh.de/wp-content/uploads/FL-Datenblatt-zur-Auswahl-der-

IRMA_0.2.pdf. A proved and tested help for us are photos of the coves (door trims) above

each of the doors with the doors closed and open (see alsoFig. 3). They show the space

available in each case and help select the correct sensors..

For each vehicle type, each year of construction and each equipment variant you need to

fill in individual vehicle data sheets which you return to the contact person of iris-GmbH

along with the pertinent photos.

3.2 Clarification of specific installation conditions

Please clarify the following circumstances well in advance of the installation as such:

• Does the vehicle lighting system or door mechanics interfere with the installation of the

sensors? An important help is a photo showing the installation situation in the upper

part of the door trim (see also Fig. 3.)

Fig. 3: Example of installation conditions in the upper part of the door trim

13

/74

IRMA MATRIX

R2 CAN Installation manual

Rev. 1.6

2018-09

• Have optical door safety systems been installed in the vehicle?

In exceptional cases IRMA and the door safety systems can influence each other. This

needs to be checked. See the document: KDAN_AppNote_Türsicherung_0.1_en.pdf

• Is the presently applicable max. installation height of the sensors of 2.40 m exceeded?

• Are there steps in the entrance area?

• Which are the height and width of the doors? In the event of unfavorable door

dimensions (very wide and low doors), the installation of 2 sensors can provide optimum

coverage of the field of monitoring. This decision must be made in consultation with iris-

GmbH.

• Are there objects in the door area permanently interfering with sensor operation while

the doors are opened and closed?

Such interfering objects are e.g. handrails, separating and guiding surfaces, seats located

in the door area or projecting into it, etc. It is possible that the reflecting surfaces of such

objects interfere with the measurement and thus distort the counting results.

Possible measures to be taken:

If there are interfering objects in the close-up range of the sensor, their influence can be

minimized by suitable modifications of geometry such as: observing a distance to

vertical guiding elements or modifying the surfaces, e.g. slanting or blackening them.

• How are the doors opened?

• Are the doors are opened automatically via an electric-pneumatic or hydraulic

system?

• Are the doors opened manually by actuation of a pushbutton in the passenger

compartment or by the first passenger boarding the vehicle or alighting from it by

pushing the door open or cranking it open?

• Are the doors opened in any other way?

Which one?

• How is the door status signalized?

• For counting, the sensor needs to receive an activation signal before.

Normally the activation and deactivation signals are transmitted by the on-board

computer in the form of a pre-defined message.

• Has the on-board computer received the necessary information on the door status

for sending such a message?

e.g.

• Door release,

• Green loop (ATG signal),

• Status for each door

• If the on-board computer cannot provide the technical option of sending

such a signal, please contact iris-GmbH to clarify possible alternatives.

• How is the 24 V DC voltage supply ensured?

• The distribution of the vehicle-provided on-board voltage supply does not form

part of the normal scope of delivery by iris-GmbH.

Is it made available at each door before the start of the installation?

14

• The supply voltage must not fall below 16°V, e.g. with an excessive number or

consumers or with the motor switched off.

• The optimal solution is a switch-off delayed by approx. 30 minutes so that

counting is possible even with the engine (and/or the on-board network)

switched off.

• Is a time-delayed power supply via the on-board network possible or

• does a timing relay need to be connected to permanent plus (see also

section 6, p. 34).

3.2.1 Important information on sensor placement

• Install the sensors in the centre of and as closely as possible to the door.

• The maximum distance between the sensor and the vehicle inside wall must not exceed

20 cm. Mounting sensors at a larger distance from the door must be agreed with iris-

GmbH before the installation.

• Install the sensors on a horizontal surface. The maximum permissible deviation from the

horizontal plane is ±5°.

If the upper door trim does not allow direct mounting, you can achieve the required

horizontal sensor position using suitable sensor mounts. Please agree any use of sensor

mounts with iris-GmbH before the installation.

• With such a sensor mount, the sensor must be placed no more than 5 cm above the

lower end of the vehicle wall.

• Objects standing vertically in close proximity to the sensor up to a distance of 3 cm from

the sensor surface can impair the counting result and must be avoided.

Fig. 4: Maximum distance to the end of vehicle inside wall

• The installation orientation must be observed in all cases; it complies with the markings

on the rear of the sensor, see Fig. 5:

• “Exterior" must face outwards when mounted.

• “Interior" must face inwards when mounted.

• In the sensor's close-up range of up to 3 cm from the sensor surface there must not be

any horizontal objects which might affect the counting result.

Fig. 5: Label on the rear - Observe mounting orientation!

3.2.2 Installation in center position above the door

Generally one sensor is used for each door. It is installed in center position in the upper

area of the door trim at a right angle to the stream of the passengers boarding the vehicle

and alighting from it.

Fig. 6: Determination of the center of the clear passage width

First you need to determine the clear passage width of the door. Objects projecting into the

passage must be taken into consideration when measuring (see item (3) in Fig. 6).

On typical bus doors being e.g. 2.05 m high and 1.30 m wide and with the sensor in the

optimum position in the center of the upper door trim, the entire (clear) passage area to be

monitored is covered by one sensor.

If it is not possible to install the sensors in the centre of the doors or of the doors are very

wide / low, the installation position and the number of sensors for each door must be

discussed and agreed in advance with iris-GmbH.

4 Mounting

4.1 Mounting of the sensor

4.1.1 Selection of the connector version

The sCON (connector for sensors) was developed particularly for IRMA MATRIX sensors for

the connection to the power supply and data transmission units.

Depending on the sensor variant, different sCON variants are available, differing in their

geometry and function:

• The sCON-S (standard) provides for the electrical connection of IRMA MATRIX sensors.

It can be used for all IRMA MATRIX sensor versions. The sensor interfaces are routed

outwards in the form of connecting lines with M12 connectors.

• The shape of the sCON-F-12 is flat and adapted to the sensor geometry which allows

the housing to simultaneously provide for mounting and electrical connection of the

sensors. This shape permits a reduction of the required installation depth behind the

cove

. The sCON-F-12 is equipped with interfaces in the form of M12 connectors.

The differences in the required installation depth due to the use of different

sensor/connector combinations are show in section 12.1.2 on p. 64.

Please note the sensor/connector combinations possible. See overview in Table 3.

4.1.2 Mounting of IRMA MATRIX sensors of the surface mount

version (DIST500-A)

The sensors of the flush mount version (DIST500-A) are placed directly on the door trim and

connected to the sCON-S (standard) from the rear.

Sensors of the surface mount version cannot be mounted together with the connector

version sCON-F-12.

The tools, width across flats and auxiliary tools required for mounting and installation are

shown in section 12.1.2, p. 64.

First drill the holes as shown in Fig. 7 with holes of 32 mm and 2 x 6 mm. The drilling

patterns are enclosed in the Annex starting on p. 63.

The sensor is mounted with the mounting screws and pertinent spring washers.

Tighten the screws with a maximum tightening torque of 3 Nm using an Allen key (size 4).

For the mounting of the standard sCON see section 4.1.2.1 on p. 19.

4.1.2.1 Mounting of the sCON-S (standard)

Fig. 8: sCON-S (standard) - overview of the connection components

The connector must be de-energized while it is connected to the sensor or disconnected

from it.

1. Insert the sCON base body with the guiding pins into the guiding holes of the sCON

connection at the sensor until it abuts.

2. Press the sCON base body to the sensor housing and keep it in place. Then tighten the

knurled screw by hand (without a tool) (corresponds to approx. 1 Nm).

If the sensor is installed in color-coated metal coves, it must be ensured that the

connection between sensor housing and cove is conductive.

If the sensor is installed in plastics coves, an additional grounding cable must be installed

between the sensor housing and the chassis (see section 5.3, p. 29).

For the technical data and assignment of the interfaces please refer to the data sheets of

the sCON-S version in question. Please observe the instructions in the data sheet.

The connector must be de-energized while it is connected to the sensor or disconnected

from it.

4.1.3 Mounting of IRMA MATRIX sensors of the flush mount

version (DIST500-F)

The sensors can be mounted either with the sCON-S (standard) and an additional mounting

set, see section 4.1.3.1, p. 20

or with sCON-F-12, see section 4.1.3.2, p. 22.
