Inputs: "MILK ", "Milkman's Service" Remote Recall Remote recall takes the lift out of normal service and parks the lift at its recall floor. It is control by TVC’s E-Director system. E-Director provides a method of monitoring and controlling a lift from a PC.
Checking Feature Descriptions The Ethos Two has a multitude of monitoring methods built in. The feature list below gives a brief description of the main checking features. Some of these features require additional external circuitry so need to be requested at panel build time.
Rope Brake Monitor This activates an input that monitors the rope brake, once tripped the lift will shut down and not move until the input is restored and the event reset in the solutions menu. Inputs: "RBM ", "Rope Brake Monitor" Test Up Limit Monitor This feature checks the test up limit on normal when at the top floor, if the limit is not seen, the controller will not allow movement on inspection or emergency electrical operation.
Event Logger Ethos Two can record over 250 different events that will give detail on problems encountered with the lift. The logger will display up to 500 events, older events are archived on the built in SD card that can accessed via the USB connection.
5.3. I/O Trace Ethos Two contains a powerful I/O trace facility to track down intermittent faults. Press: I/O Trace The I/O Trace screen can be setup to keep a record of 50 I/O transitions for up to 8 Inputs or Outputs. Use the Signal button to select I/O that is of interest.

7. Parameter Adjustment and Storage Most commonly used parameters can be found within their relevant screens e.g. call dwell settings can be found via the Car button. All other settings including commonly used ones can be found by touching the Settings button from the home screen.
Press: Settings → Modify Settings The Ethos Two unit will now proceed to import the modified parameters by firstly overwriting the current backup JSON file with the current user JSON file, then editing the current user JSON file with the required changes.
Press: Toolbox → Connect SD1 The Ethos Two unit should now appear as a USB Flash Drive on the connected PC Backup the entire SD card to your local machine. Move the factory, user and backup “*.json” files and any binary files located on the SD card’s root into another directory on the SD Card e.g.
Page 51
Now program the lift board following these steps: Move the SD card from the display to the lift board. Move the upper DIP on the display board (SW4-2) into the ON (left) position. (as shown) Reset the display processor by pressing the reset button (under the SW4 DIP switches).
9.2. ETSD Card Software Upgrade (only applies if ETSD card fitted) The ETSD bootloader searches for a binary file named “E2_ETSD_Brd_YYYYMMDD_VERS.bin”. Ensure only one ETSD binary file is stored on the SD Card’s root directory before flashing. Insert the SD Card into SD card reader J2 on the underside of the ETSD card.
10. Expansion Modules The Ethos Two system is modular so it can be easily expanded to suit any lift system. Listed below are all the available module options. 10.1. Call Modules 2 types of call module are available 8 way or 16 way, both modules are designed for a 3 wire call system with 24V d.c.
Feature I/O can be viewed through the MMI via the View I/O button 10.3. Serial Network - Installation Guidelines This general guide is designed to give an outline of installation and setup of an Ethos Two serial network. Please refer to relevant installation pages for more in depth information. Machine Room Install main panel.
None of the nodes configured correctly. If a network has failed to respond to commands sent out by the Ethos Two then repeated tries will be made to establish communication. When the network connection is established this is also reported as an event in the Ethos Two event log.

Hydraulic Installation. The Ethos Two can be used in hoist mode via “Hoist Mode” button. This allows the motor to run if the panel is on Inspection Control (TTR) or Emergency Electrical Operation (PTR). It will ignore missing car and call modules and ignore missing door limits and TFR/BFR limits.
Page 65
For stopping, the “Brake Delay” determines time to hold zero speed before the drive is signaled to start the brake drop sequence. The brake apply timer (#D05) in the drive should be set to a value that allows the brake to drop before the drive is disabled (Note: Ethos setting “Disable Delay” is not used on E300 systems).
Testing of Ethos Two Features for “Protection Against Unintended Car Movement” The Ethos Two is certified for various UCM solutions (EN81-20 5.6.7), below is a list of the key systems and a description on how the Ethos Two elements of each system can be tested.
Page 67
To test the verification of this feature perform the following tests: a) Before the Ethos Two goes on a journey remove the “SGS” input to the panel or Ethos Two. Ethos will log a manually resettable event “Safety Gear Operated” this can be reset via the solutions menu.
Page 68
STR pneumatic timer) k) The Ethos Two will log a “Not in Door Zone – A3” event which is manually resettable via the solutions menu. This simulates the situation when the car has unintended movement outside the door zone whilst the car has its doors is open.
Equipment Immunity The Ethos Two controller is designed to comply with current EMC regulation limits. Please be aware that the use of high power radio transmitters over and above these limits, in the vicinity of the controller, may cause the processor or other equipment to malfunction.
11.4. Maintenance Required The TVC Ethos Two Controller has been designed to require as little routine maintenance as possible. The controller does however contain various mechanical parts that will require routine checking. The maintenance list below is not definitive and should be used as a guide. Lift usage will play a major role in wear and maintenance. It is the user’s responsibility to judge when various components require replacing.
Direction and control signals are via a serial communication loom from the Ethos Two lift control microprocessor. Speed is usually via the analogue pattern loom, giving direct floor approach.
Page 72
Ensure that the following parameters are set in accordance with the motor nameplate, encoder and lift mechanics. If these details are incorrect, make sure parameters in the drive and Ethos Two match anything modified. e.g. motor RPM etc. If any significant differences are found, contact TVC:...
Page 73
Note: Some Gearless Permanent Magnet (RFC-S) motors have low saliency. In this instance a Stationary autotune will fail to calculate the encoder phase offset value correctly. TVC advises a rotational tune on a permanent magnet motor. This is the only guaranteed way to learn the motor parameters correctly.

Do not save these modified parameters in the drive! A power cycle will restore the drive to the original values. Note: This only applies to pattern Ethos Two applications; It is customer’s responsibility to ensure that motor can be run above contract speed without sustaining damage, check with motor manufacturer.

13. Hydraulic Lift Installation Guide 13.1. Introduction The Ethos Two can be configured to control various hydraulic setups including: Standard hydraulic DOL / Star-Delta. Soft-Start / ELRV Hydraulic Block and Hydraulic with VF Drive (Bucher ELRV or Algi). 13.2. Step by Step Installation Sequence The following sequence should be followed when installing the panel and commissioning the lift.
Page 81
The stopping accuracy and the learnt Door Zone Stop Distance value is dependent upon the control profile of the hydraulic system after the Ethos Two has removed the low speed signal. Usually the optimal Door Zone Stop Distance value given a lift speed of 0.63m/s is between 12mm and 15mm.
Appendix A1: Devices Needed for Initial Site Installation. Fit and wire the following external devices to the controller terminals to allow the system to operate under “Inspection Control” for initial site installation. Additionally set “Hoist Mode” in the MMI checklist so door limits and car network events are ignored. If in doubt please contact the factory.
Appendix A2: Devices Needed for Initial Site Installation - Lift controller using the Limax3CP. Fit and wire the following external devices to the controller terminals to allow the system to operate under “Inspection Control” for initial site installation. Additionally set “Hoist Mode” in the MMI checklist so door limits and car network events are ignored.
Appendix G: Limax3CP Setup Guide (only if fitted) This guide gives detail on the use of the Limax3CP with an Ethos Two controller. The unit is shipped from TVC pre-configured and must only be used on the lift specified on the drawings, contact TVC for further support.
