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.
