2.3. System Overview
The TVC Ethos Two controller is a sophisticated but easy-to-use lift control system. Ethos Two has been developed
to be user-friendly for the installer, tester, service and call-out engineer whilst offering lifetime value to the end-user.
Ethos Two provides helpful test and fault finding routines to enable fast installation, commissioning, and trouble-
shooting.
The overall Ethos Two Lift Control System comprises various electronic modules and a motor panel section plus
shaft and car wiring. The Ethos Two main unit and associated modules are usually mounted in a single cabinet and
linked via the trailing flexes to a car mounted module.
The lift motor operation is controlled by the motor panel section, which receives signals from the microprocessor,
such as pilot relays for up, down, brake, open door and close door signals. The motor panel section sends signals
back to the microprocessor units regarding which lift function it is carrying out, i.e. moving up, moving down, opening
or closing doors, door zone or locks made etc.
The motor panel section also sends and receives signals from the shaft and car, these being locks and safety circuit
signals from the shaft wiring, door operator, car gate and safety circuit signals from the car wiring.
Signals to and from the shaft and car are also transmitted and received by the microprocessor unit. These include
landing calls, position indicators; position resets and fire switch etc. from the shaft wiring and car calls, position
indicators, service switch controls etc. from the car wiring.
A basic Ethos Two system comprises of the main control module, which includes the CPU board + TFT MMI Display
interface, Motherboard I/O and an associated Car module to interface to car calls and car I/O. Various options are
available for landing call entry, including 8 way or 16 way call cards, QuickFlex landing nodes or the HCD navigator
system (See TVC factory for details). The main control module is equipped with a clear and intuitive touch screen
user interface with short cuts for fast and easy menu navigation.
Systems requiring more floors and or features can take advantage of plug in expansion modules; such as the 24
way output module and 8 way input or output modules. As the Ethos Two system is a modular system multiple
modules can be plugged together to form one contiguous modular Ethos Two system.
The Ethos Two control system uses a distributed field-bus network for interfacing calls and I/O to the main Ethos
Two lift controller. The field-bus uses a proprietary CAN bus protocol developed by TVC. The system is used in
place of normal discrete wiring for calls and car related input and outputs. Instead of each push and call lamp being
directly connected to the panel, in the motor room, they can be connected to local modules that are distributed about
the car and lift shaft. This will depend on particular installation requirements.
The systems voltages are derived from a transformer/power supply module mounted on the motor panel and are fed
via a wiring looms to the control modules. High reliability, field proven industrial standard components are used
throughout the system and are readily available from many sources.
The system has signal protection, where all external incoming signals are optically isolated and filtered. Motor panel
signals are mainly at 110Va.c and 24Vd.c. Call signals e.g. landing and car push feeds / acceptance lights are
24Vd.c.

2.4. System Key Features.
Ethos Two is a modular lift control system, various expansion cards can be fitted to the system to allow for more
calls and features. The system can be configured to function as an 8 car dispatcher-less group or a Hall Call
Destination system in conjunction with the TVC Navigator system. The system uses several CAN bus connections to
facilitate this. Consult the contract drawings and expansion module section for further information.
The system can be configured with the following limits:
Number of Floors: 64 front and rear openings, short floors (min 20mm), long floors.
Group Operation: 8 cars Dispatcher-less or 8 cars Hall Call Destination.
Machine: Traction - AC / DCSCR, Hydraulic, Hydraulic – Electronic.
Speed: 0.3 – 8.0 m/s.
Features: Re-levelling / Advanced door opening / Advanced brake lift.
See Service / Feature descriptions for full list.
The Ethos Two builds on the original Ethos controller from TVC with these key new features:
Ethos Two is based around a simple, intuitive touch screen that provides a clear indication of the lift’s current status.
The screen gives the user all the information they need, at their fingertips. Extensive help for all features and faults
is displayed on the screen in plain English.
The new Car Module contains the “RideSensor” option. This records car ride performance via a 3-axis
accelerometer, checks the ride performance in real-time and can spot any issues before the passenger does. G-
force-limit records ‘Over G’ events such as crash stopping or safety gear operation which is useful for analyzing
passenger claims of abrupt journeys.
The new event logger stores every event against a time-line including direction, position, load, inputs & outputs.
Colour coded fault finding filtering critical and non-critical events and searching options quickly help get to the core
of a problem. All events are stored on a large memory Micro SD Card this can store years of archived events for
future reference.
Service Alerts record the number of operations of key components. As well as recording door and journey counts, it
records door operations per floor for an indication of landing door gear wear.
Parameter storage on the SD Card allows easy transfer of settings, this makes upgrades and repairs faster and
simpler, no special software is needed to upgrade the firmware of the device, so software upgrades can be
performed without waiting for an engineer with dedicated tools.
The Ethos Two has many handy automated features including: Automated shaft self-learning and automatic
stopping point adjustment for quicker installations.
Integrated speed pattern generation with “Direct-to-Floor” approach, so no need to adjust slowing distances and
speeds for different floor heights. The pattern also allows alternate speed profiles to be selected. Profiles include
ride settings for Comfort, Economy and Ultimate Performance.
A serial drive interface provides fault information from the drive, integrated into the logger.
Hoist Mode allows the elevator to be controlled during installation without all features connected. Jog motor feature
gives the engineer the option to run the motor from the screen to check starting and stopping performance.
Machine room-less installations are easier with the CAN serial modular system that allows for flexible installations
with either shaft or panel mounted modules. The main control module also has a remote MMI feature that can be
mounted in the smallest of rescue panels.
