Introduction

3 Introduction

3.1 "Modular Door Control" over the course of time

WABCO has produced bus door drive and control components for many decades. Over the years,
several generations of door control systems have been developed which have met the many
requirements of vehicle manufacturers and users as well as legislation.
Their continuous further development led to the introduction of the new MTS2 (2nd generation modular
door control). This system is based on the experience of the MTS-PX/EX and takes electronic door
control to a new level. It combines the technical requirements of modern buses and coaches with the
goal of a cost-effective system structure and the fulfilment of the extended legal requirements of the
ECE R107 regulation.

3.2 MTS2 - 2nd generation modular door control system

The MTS2 was developed building on the experience of the MTS-PX/EX. It was first used in series
production in 2013 and is now well established on the market. Like the first MTS generation, it can be
used for all types of doors, whether pneumatic or electric. For this purpose, all components of the door
control system for both the pneumatic and electric drives have been completely redesigned.
In order to comply with the specification of a simplified system layout, the layout of the system has been
significantly improved. The internal MTS-PX/EX system bus is no longer required; all MTS2 ECUs are
directly connected to the vehicle CAN bus as so-called multi-master units. As a result, the interface
to the vehicle has been standardised. The connection to the vehicle via conventional cabling is no
longer necessary; all MTS2 ECUs are connected to the vehicle architecture exclusively via a CAN bus
interface.
One MTS2 system can control up to 8 doors in a vehicle. In comparison to the 1st generation MTS,
each ECU for pneumatic doors is capable of controlling up to 3 valves and monitoring 4 door wings.
This means that one ECU is sufficient to control two doors, one of which may be equipped with a
separate wing control. Furthermore, the MTS2 can control both outward-swinging doors of a touring
coach using only a single ECU.
The architecture of the pneumatic control of the doors has also been significantly simplified. Thanks to
an innovative new door control valve with integrated safety function, the separate emergency switching
valves used previously can be omitted and the emergency cocks (both outside and inside) can be
connected directly to the door control valve.
In combination with the new door control valve, innovative emergency cocks enable automatic resetting
of the door function after emergency cock actuation from the driver's seat. It is therefore no longer
necessary for the driver to leave his driving position in order to put a door back into operation after
actuating the emergency cock. In addition, the emergency cock (inside) is closed while driving in
accordance with the legal requirements according to ECE-R107.
To further simplify the installation, all pneumatic components are equipped with so-called "push-to-
connect" connections (6 or 8 mm). Pneumatic lines can thus be easily and quickly connected to the
MTS2 components without further screw connections.
As before, the pneumatic doors are monitored via potentiometers mounted directly on the rotary
column and via pressure switches screwed into the MTS2 solenoid valve. Due to mechanical coding,
no adjustment of the potentiometers is required. Electrically driven doors can equally be monitored with
the help of these potentiometers; alternatively, pulse generators installed in the engine can be used
together with an limit switch.
A simple teaching process is used to balance all the tolerances during initial start-up or when the ECU
is replaced for every door. For this, it is necessary to move the doors once to both end positions by
continuously actuating the workshop button.

6
Introduction

The proven damping principle has been further developed for pneumatically operated doors. The end
position damping is integrated in the door valve. What is new is that both the damping in opening and
closing direction can be set separately. In addition, the cylinders are equipped with adjustable throttles
acting in both directions. This provides a wide range of adjustment options to ensure optimum door
travel for different types of doors.
Optionally, electrical terminal strips can be connected directly to the MTS2 and can be monitored
directly without additional devices.
The control unit is delivered with a bootloader. Depending on the type of door, a suitable application
program is loaded into the ECU during start-up at the vehicle manufacturer, so that a tailor-made unit
is created. In addition, the door travel can be adapted to the vehicle conditions by means of various
parameter settings.
The MTS2 system can be diagnosed; diagnosis is carried out via UDS. As before, the WABCO
Standard Diagnostic Interface must be used in conjunction with the new MTS2 diagnosis to connect the
ECU to the diagnosis system.
As known from the MTS-PX/EX, the MTS2 also has - depending on the system configuration - up to
9 inputs and 7 outputs, which can be used freely. The programming and definition of the functionalities
are the responsibility of the vehicle manufacturer.

The MTS2, like the MTS-PX/EX, can be used as a one-door controller. For this purpose, each door is
equipped with an ECU which controls and monitors the respective door.
With this system variant, the ECUs also offer the option of freely using unused inputs and outputs.
This enables different configuration options, adapted to the needs of the manufacturer. The number
depends on the respective system configuration (one or two valve control).
Unlike in the past, each ECU is connected directly to the vehicle CAN bus with the same rights (multi-
master system). This means that the previous separate MTS door CAN bus is no longer required.

As an alternative to one-door control, the MTS2 can also control up to 3 valves with one ECU and read
in up to 4 potentiometers. This makes it possible to control two doors in parallel from one ECU, where
it is even possible for one of the doors to have a separate door wing control. With this configuration,
all vehicles with up to two doors, such as standard city buses, intercity buses and coaches, can be
controlled with just one ECU.
With a multi-door control with 3 valves, all available inputs and outputs are used and no pins remain for
free disposal.

5 System components
In order to ensure perfect interaction between door electronics and door mechanics and thus passenger and
operational safety, WABCO is usually required to carry out tests and, if necessary, make adjustments. To
use the system in series it is imperative to discuss this with the door or vehicle manufacturer and to obtain
his approval if the joint assessment was positive.

5.1 MTS2 solenoid valve

The MTS2 valve operates the pneumatic door cylinders responsible for opening and closing the doors.
The safety functionality integrated in the valve leads to a pressureless function of the doors in the event
of an inside emergency cock actuation in accordance with the blocking specification under ECE R107.

System components

Fig. 1 Circuit diagram MTS2 solenoid valve

5.2 ECU
The ECU controls the MTS2 solenoid valve. Depending on the configuration, either one ECU is used for
each door or two doors are controlled per ECU. The ECU is connected to the vehicle electrical system
via the connection to the vehicle CAN bus.
Depending on the door drive, either the ECU for pneumatic doors (446 160 006 0) or the ECU for
electric doors (446 190 016 0) is used.

5.3 MTS2 door cylinder

The MTS2 door cylinder is compatible with the MTS system with WABCO linear cylinders. Due to the
use of aluminium and plastic, it is approx. 500 grams lighter than a linear cylinder from the MTS system.
The pneumatic connection is made via the integrated plug connections. The door running speed can be
adjusted via the variable throttles of the cylinder. It is available in three stroke lengths: 140 mm, 160 mm
and 180 mm. The diameter of the cylinder is always 50 mm. The piston has an M14x1.5 thread. One
MTS2 door cylinder is required per door wing.

5.4 Emergency cock

The MTS2 is designed for the use of one emergency cock respectively inside and outside the vehicle.
Manual actuation is effected by turning the emergency cock by approx. 90°. When released, the
emergency cock is reset by a spring. It is used in combination with the MTS2 door valve and has plug
connections. The sensing of the switching position by microswitch is optionally possible.

11
Start-up

5.5 Pressure switch

The monitoring of the opening and closing process and the detection of power- and pressureless
switching is carried out via pressure switches. They have a switching pressure of 4 +/- 0.4 bar.
Two pressure switches are required per door valve.

5.6 Travel sensor

The travel is sensed by potentiometers or incremental encoders mounted directly on the rotary
columns. The values of the potentiometer are processed by the ECU as relative values. If a travel
sensor is replaced, the door must be learned again.

6 Assembly
–– Follow the vehicle manufacturer's installation details.

7 Start-up
For start-up of the MTS2, the ECU must be fully connected. Local start-up (on a test stand / without
CAN connection) of the door is possible. Start-up consists of a learning procedure to be carried out
before series use. The values of the door leaf end positions [ZU (closed), AUF (open)] are learned and
permanently stored in the ECU.
Operating elements for learning
„„ Service switch (SVC)
„„ Workshop button (TT)
„„ Entrance lighting (ESB)

All MTS2 series ECUs are supplied without the application or a parameter set. Both must be
loaded into the ECU during start-up (factory or workshop) according to the respective door
design and desired functionality.

7.1 Learning the doors

The door control must be learned for each door of the vehicle in order to compensate production
tolerances of the doors. All the learned values can be read out with the diagnosis.

During the learning procedure, the entrance lighting of the respective door flashes. The
number of flashing pulses depends on the door position. The lighting flashes once for door 1,
twice for door 2, and so on.

7.1.1 Requirements
„„ The ECU contains the door- and vehicle-specific parameter set.
„„ The vehicle is stationary (ground potential on pin 12/18 C3 at the ECU of door 1).

12
Start-up

„„ The ignition is switched on (24 V on pin 3/12 on the ECU of door 1 or ignition signal on the CAN
bus of the vehicle).
„„ The service switch (SVC) is active.
„„ Operating voltage and pressure are OK.

7.1.2 Learning procedure

A learning procedure is carried out as follows:
1. Close door.
2. Continuously press workshop button.
ÖÖ The door moves to the AUF (open) position.
ÖÖ After approx. 7 seconds, the entrance lighting of the learned door flashes: once at door 1,
twice at door 2, etc.
3. Release workshop button.
ÖÖ The flashing indicates the end of the learning procedure AUF (open).
4. Open door.
5. Continuously press workshop button.
ÖÖ The door moves to the ZU (closed) position.
ÖÖ After approx. 7 seconds, the entrance lighting of the learned door flashes: once at door 1,
twice at door 2, etc.
6. Release workshop button.
ÖÖ The flashing indicates the end of the learning procedure ZU (closed).

The teach-in process is confirmed by the entrance lighting flashing only after the door has run
smoothly.

7.2 Learning the system

1. Switch off ignition.
2. Switch on ignition.
3. Carry out learning procedure on door 1.
4. Repeat steps 1 to 3 for all other doors.
ÖÖ The system is learned.

7.3 Standstill detection

The standstill is detected via the C3 speedometer signal (pin 2/9) and via CAN bus signals.
The speed threshold of the C3 speedometer signal for "vehicle stationary" is approx. 3 km/h.
The CAN bus signal "FAHRT" (driving) is linked to the "C3 speedometer signal" or to the CAN bus
signal "STC3_3" of the first door.
The link can be selected via parameter P01 Chapter "7.4 Parameters", page 14.
When linking to the CAN bus signal "STC3_3" of the first door, pin 2/9 on door 2-8 can remain
unconnected.

13
Diagnosis

If after switching on the supply voltage a valid status "vehicle stationary" or "vehicle moving"
was once received by the ECU, this information is always linked to the signal of the first door.
The signal must have a "vehicle stationary" status so that the doors can be opened.

Once a valid status "vehicle stationary" or "vehicle driving" has been received, the status "not
defined" and "signal not available" are internally set to "vehicle driving".

The door can only be opened if the door control detects the "vehicle stationary" state.
Emergency actuation is excluded from this.

7.4 Parameters

7.4.1 Standstill detection / Emergency cock blocking (P01)

Signal selection for standstill detection (v < 3 km/h) and emergency cock blocking (v > 5 km/h):
"C3 speedometer signal" or status signals "STC3_3" / "STC3_5" of the first door.
Possible setting values:
„„ C3 speedometer signal
„„ Status signal STC3_3 (T1)
„„ Status signal STC3_5 (T1)
Default setting: C3 speedometer signal

8 Diagnosis
As before with the MTS-PX/EX, the MTS2 is diagnosed by means of a diagnostic program via the
Diagnostic Interface and the corresponding cable. A standard PC/laptop (WIN 10) and a connecting
cable between the Diagnostic Interface and the door system are also required. The type of connecting
cable required depends on the diagnostic socket installed by the vehicle manufacturer.
The Diagnostic Interface serves to connect the PC/Laptop with the vehicle control system. It is included
in the delivery of the connecting cable to the USB port of a PC/laptop.
