1 Introduction The “V-COM” (Velocity Control Module) is a flexible positioning system that can utilise various position feed back sources to allow the Ethos Controller to be able to accurately control high speed lifts using all modern drive technologies. This manual covers the “Advancing Selector with Direct Drive Interface” variant. Functionality is as below:-

Lift speeds up-to 6m/s. Re-levelling functionality. Advancing selector. Emergency terminal slow down (ETSD) functionality built in (option). Incremental pulses can be taken from the governor or motor encoders. Outputs for dual DZ ethos re-levelling and advance door opening system. User interface contained within Ethos MMI. Absolute positioning for ETSD. Battery back up included. Hand-winding feature.

Software written to MISRA C Guidelines.

2 Limits Speed:- The product will control a lift of maximum speed 6 m/s. In this configuration. Position Accuracy:- To +/- 1mm depending on drive / brake accuracy. Floors served:- 64 floors and 200m travel. Direct Approach:- This configuration does not offer direct floor approach, if this is

required please use the drive pattern interface version. Typically this version would require 80mm of levelling from 4m/s leading to 1 to 2 seconds of levelling if tuned correctly.

3 Basic Positioning Functionality.

3.1 Velocity Control The system uses scaled quadrature pulses for velocity control and position derivation when running. Quadrature pulses can be supplied from the motor encoder or governor-mounted encoder. These can be 5V differential signals, or 12 volt push pull signals.

3.2 Position Resets / Indexing The unit uses terminal resets (BFR and TFR) and DZ signals to validate the incremental encoder derived position in relation to the lift position in the shaft. The unit also uses an absolute encoder position input when in enhanced mode e.g. speeds above 1.6m/s where ETSD functionality is required.

3.3 Door Zones Door zone signals can be supplied from either a magnetic proximity sensor or retro reflective laser sensor. A 24V d.c. supply is provided to power these sensors.

3.4 ETSD and Over speed Monitor Lift speed and position is constantly monitored by the V-COM Master (A) processor, based on feedback derived from an incremental encoder mounted on either the lift motor or the overpeed governor. The Master (A) processor will determine when to bring the lift to a controlled safe stop by requesting an emergency slow down or worst case crash stopping the lift, if speed is excessive towards the terminal floors. As an option, a second built-in speed monitoring Slave (B) processor can be used, taking an absolute position derived from either an absolute multi-turn encoder mounted on a belt driven system or the over-speed governor, or from a Schmersal USP wire system. The Slave (B) processor will determine independently when to bring the lift to a controlled safe stop by requesting an emergency slow down or worst case crash stopping the lift, if speed is excessive towards the terminal floors.

5.1.2 Parameter Definitions Parameter Description Contract Speed Application contract speed in m/s Emer. Decel 1st Rate. Sets the rate of an imaginary deceleration curve extending

from the trailing edge of the top and bottom terminal door zones for use by the Emergency Terminal Slowdown function. If the detected speed profile of the lift was seen to cross this curve, then a terminal slowdown at an increased deceleration rate would be invoked. (See Section 8)

Emer. Decel 2nd Rate. Sets the rate of a second imaginary deceleration curve extending from the trailing edge of the top and bottom terminal door zones for use by the Emergency Terminal Slowdown function. If the detected speed profile of the lift was seen to cross this curve, then the V-COM OK relay would be dropped causing a crash stop. (See Section 8)

Learn / Error Speed Sets the reference speed at which shaft learning, or fault recovery will take place.

Number of Speeds Limits the number of discrete speeds available (includes Learn Speed but not Levelling Speed). [See TVLD 421]

Learn Slowing Dist. Sets a delay when slowing from learn speed on detection of TFR / BFR, to reduce the time spent travelling at levelling speed.

High 1 Slowing Dist. Sets the slowing distance for High Speed 1 (generally for 1 floor runs)

High 2 Slowing Dist. Sets the slowing distance for High Speed 2 (generally for 2 floor runs), if required.

TVL 294 ISSUE 3

12/06 14

High 3 Slowing Dist. Sets the slowing distance for High Speed 3 (generally for 3 floor runs), if required.

High 4 Slowing Dist. Sets the slowing distance for High Speed 4 (generally for 4 floor runs), if required

High 5 Slowing Dist. Sets the slowing distance for High Speed 5 (generally for 5 floor runs and above), if required.

Floor Trims Allows the offsetting of each floor level with respect to the centre of its learnt Door Zone tape. (E.g. If the lift stops consistently 3mm high at a particular floor, then setting the floor trim for this floor to –3mm will stop the lift at floor level.

Leveller Overlap Sets the distance around the centre of a learnt door zone tape, which is considered floor level. This may be increased to accommodate a less-responsive drive system

Motor Speed Sets the motor speed in RPM at the required contract speed.

INC Encoder Pos. Dir. Sets the direction of travel, in which the encoder feedback value for the incremental encoder is seen to increase, when viewed in the Abs/Inc Counts Screen (see next section)

ABS Encoder Pos. Dir. Sets the direction of travel, in which the encoder feedback value for the absolute encoder (if used) is seen to increase, when viewed in the Abs/Inc Counts Screen (see next section)

Top Term DZ Side Sets the top terminal door zone side (front or rear). Bottom Term DZ Side Sets the bottom terminal door zone side (front or rear).

6 Shaft Learn Procedure A “shaft learn” procedure must be carried out before the lift can run at high speed and be entered into service. During the learn, positions of all door zones and TFR / BFR resets are noted and stored in non-volatile memory on the V-COM unit. This section should be read in its entirety, prior to carrying out a shaft learn. The commissioning engineer has the sole responsibility for taking adequate safety precautions during the carrying out of this procedure.

6.1 Preliminaries

6.1.1 Physical checks Check the following before taking the unit off TEST control:- Check all safety circuits and ensure all safety switches are in order. Ensure that the panel is on TEST control. The lift must be capable of travelling at approximately 0.25m/s, in automatic. The lift should be empty or balanced. There should be no rope slip. Have the TFR and BFR reset switches been installed and set to the correct distance from the terminal floors? Before a shaft learn is started ensure that TFR and BFR signals work correctly, as these are vital for stopping the lift at the terminal floors! Have the reflective strips or magnets for the door zone sensors been installed at every floor? (With the lift at each floor level, the laser dot (or magnetic sensor) must be in the centre of the door zone reflective strip (or magnet). Are all door zone sensors working? (LED DZF/DZR, as appropriate (see Section 4) should illuminate over the entire length of the door zone reflective strip (or magnet). Are all incremental encoder signals wired in? Has the Absolute Encoder been fitted if needed? The lift must be able to stop on the top and bottom terminal door zones i.e. no bouncing off DZ – (check setting of brake).

6.1.2 Parameter / Configuration Checks Does the incremental encoder count in the correct direction? (This can be checked, by looking at the “V-COM Toolbox – Abs/Inc Counts” screen – Section 5), whilst moving the lift on TEST control. Correct, if necessary, by changing the direction in the “V-COM Settings – Encoder Data – INC Encoder Pos. Dir.” menu. Does the absolute encoder, if fitted, count in the correct direction? (This can be checked, by looking at the “V-COM Toolbox – Abs/Inc Counts” screen – Section 5), whilst moving the lift on TEST control. Correct, if necessary, by changing the direction in the “V-COM Settings – Encoder Data – ABS Encoder Pos. Dir.” menu. Has the drive been configured for learn speed (0.25m/s)?

TVL 294 ISSUE 3

12/06 18

6.2 Starting Move the lift on TEST control and position the lift ideally at the bottom floor (on BFR) and on the bottom terminal door zone. (If the lift is off BFR, then the lift will “seek BFR” at learn speed, during the first phase of the shaft learn. If the lift is on BFR but not on the Bottom Terminal DZ, then the lift will travel to the top terminal floor before travelling back down to seek BFR. To avoid this situation, ensure that the lift is either off BFR, or on BFR and the Bottom Terminal DZ.) With reference to the ETHOS manual, disable the doors (by setting “Door Disable” in the ETHOS Toolbox. Place the Ethos in service at this point by switching on to NORMAL control (off TEST control). In the V-COM toolbox menu select “Learn Shaft” and confirm. The learn screen shows the following information:- LZ: The number of learnt door zones. St: The current learn phase. MEr: Current learn errors from the Master processor. SEr: Current learn errors from the Slave processor. IVel: Velocity taken from the incremental encoder (mm/s). IDist: Position in the shaft. (floor one will be set to 10000mm at start of learn) Sp: Current speed selected. Dir: Current direction selected. By pressing the back button other areas of the MMI can be viewed. The Abort button will stop the current learn.

6.3 BFR Seek Once the ETHOS switches to shaft learn service, this overrides all but TEST control, and non-op service, fire service etc. will be ignored in learn mode. The lift will move lift down to BFR and DZ at learn speed (usually 0.25m/s) if not already on BFR and bottom terminal door zone. (If the lift is on BFR but not on the Bottom Terminal DZ, then the lift will travel to the top terminal floor before travelling back down to seek BFR. To avoid this situation, ensure that the lift is either off BFR, or on BFR and the Bottom Terminal DZ.)

6.4 Learn Phase 1 Up Learn Following detection of BFR, the ETHOS will commence the “Up Learn”. The lift will now travel to the top floor, at learn speed, recording door zone edges and BFR / TFR positions.

6.5 Learn Phase 2 Down Learn After stopping at the top floor on TFR and the Top Terminal DZ the lift will travel back down to confirm DZ locations. This second pass also eliminates hysteresis problems created by magnetic DZ sensors. The lift will stop on the bottom terminal DZ and then store its DZ position list in non-volatile memory. “Await Burn” is displayed during this process. Once this is complete the ‘Learn Successful’ screen will be displayed. The user must accept the learn before the lift can be put into service. If any errors are seen on the learn, refer to Section 9.

6.6 Shaft Learn Completion On successful completion of a shaft learn, proceed to Section 7 – V-COM Speed and Slowing Distance Setup.

7 V-COM Speed and Slowing Distance Setup.

7.1 Preliminaries Make sure the panel is in service and “Door Disable” and “Prepare to Test” are active. Complete a “Shaft Learn” procedure before setting drive speeds and slowing distances.

7.2 Step 1 – Obtaining Recommended Slowing Distances Go to the “Recom. Max Slow Dst” Screen in the V-COM toolbox menu. The screen should look similar to the one below (ignoring numeric values):-

Recom. Slow Table Rn Str End MxSlDist. 1 11 12 2060mm 2 11 13 4190mm 3 10 13 6320mm 4 9 13 8450mm 5 7 12 10580mm SET BACK

The screen gives a list of the shortest one, two, three, four and five floors runs. For example from the screen shot above, the shortest one floor run is between floors 11 and 12. The figure next to this is the maximum slowing distance the first high speed (High1) slowing distance can be set to, to achieve “High1” speed on this one floor run. The distance is calculated by allowing distance for acceleration, adding an arbitrary distance at constant speed and also adding distance to slow into the target floor. If the slowing distance for High1 is set to a greater value than this V-COM will choose the next slowest speed for this run e.g. learn speed.

7.3 Step 2 – Initial Setting of Recommended Slowing Distances Pressing the “SET” key will burn these recommended maximum-slowing distances into the slowing distance table for each speed. So the distance for the one floor run is saved as the slowing distance for speed High1, the distance for the shortest two-floor run slowing is saved as the slowing distance for speed High2 etc.

TVL 294 ISSUE 3

12/06 21

7.4 Step 3 – Speed Setup Taking a note of the start and end floors for each speed / floor run, the drive speed parameters can now be adjusted to achieve the optimum run for each speed (see TVLD423). This is done in the following sequence:- Take the car to the shortest single floor run start floor, in this example floor 11. Now place a car call for floor 12 via the controller MMI. The controller should select “High1” speed for this run (This can be seen on the Main screen under the speed heading). Once the run is achieved, the drive speed can be increased to eliminate any excess levelling into floor (see associated drive manual for reference). Note:- The LTLR timer in “Customer Settings” may have to be temporally increased to get into floor level. If the drive is shooting through floor decrease the first high-speed parameter on the drive. Whilst setting-up the first high speed, check that acceleration and deceleration rates are satisfactory, making any adjustments in the drive, with reference to the associated drive manual. NOTE: Changes to acceleration or deceleration rates at a later stage could

require re-adjustment of speeds set prior to the change. Once this shortest one floor run is setup, with minimal levelling, move the car to the start of the shortest two-floor run. The sequence of drive speed parameter adjustment needs to be repeated for the second high speed. This is to be repeated until all speeds / runs are setup.

7.5 Step 4 – Adjustment of Slowing Distance on Contract Speed Runs Whilst setting up a speed if contract / maximum speed is achieved on the drive and excessive levelling is still being experienced, the slowing distance for this speed can be decreased in “V-COM Settings – Slowing Distances” For example we have set up speeds for 1, 2 and 3 floor runs and whilst setting the speed for the shortest 4-floor run contract speed is reached. The drive speed setting is to be left set at this speed, go to the slowing distance menu and decrease the distance for speed “High4” till levelling is eliminated. This example installation will then not need to use “High5” speed, this can be turned off by limiting the number of speeds to 5 in “V-COM Settings – Misc. Settings – Number of Speeds.”

7.6 Step 5 – Completion of Speed Setting The controller should now be able to perform any run within the shaft, selecting an appropriate speed dependant on the distance to the target floor. So from the example above a run from floor 9 to 13 would use speed “High4”. If the floor heights are non uniform and a large single floor run is targeted the V-COM will select the maximum speed it can achieve for this run based on the entered slowing distances, not necessarily “High1” speed.

TVL 294 ISSUE 3

12/06 22

7.7 Step 6 – Saving Settings Once the adjustment of the number of speeds and slowing distances has been completed, all settings can be backed up in the ETHOS “Memory Management” menu.

7.8 Step 7 – Floor Level Trim Adjustment Floor levels may now be checked. The lift should be ridden to every floor in both directions of travel, recording errors in floor level using the table in Section 11. Using the formula given, floor level trim values can be calculated (see also TVLD422) and should be entered for each floor via the “V-COM Toolbox – Floor Trims” menu. If a floor level is wildly out, check position of the DZ reflector / magnet at that floor. NOTE: If a reflector / magnet is moved, both the shaft learn and speed setting

processes will need to be repeated.

8 Emergency Terminal Slowdown The ETHOS/V-COM system provides a two-stage means of effecting a slowdown at terminal floors, should normal slowing not occur. This is enhanced where a secondary absolute positional feedback is provided for monitoring by the V-COM Slave processor.

8.1 Operation Figure 1 below shows the principle of operation.

Fig. 1: Illustration of V-COM Terminal Slowdown The system defines three areas at each terminal floor. The boundary between the ‘Safe Area’ and the ‘Emergency Decel Area’ is defined by an imaginary deceleration curve (set by ‘Emer Decel 1st Rate’ in the ‘V-COM settings’ menu) extending from the trailing edge of the terminal floor door-zone. The boundary between the ‘Emergency Decel Area’ and the ‘Crash Stop Area’ is defined by a second imaginary deceleration curve (set by ‘Emer Decel 2nd Rate’ in the ‘V-COM settings’ menu) extending from the trailing edge of the terminal floor door-zone. The position of the lift is constantly monitored by the V-COM Master processor and additionally by the Slave processor, if used. Under normal operation the lift will slow at the terminal floor well within the ‘Safe Area’. If the lift has not slowed normally, the detected combination of speed and position will place the lift into the ‘Emergency Decel Area’. At this point, the V-COM signals the ETHOS to instigate slowing at a steeper than normal deceleration rate (shown by the thick dotted line in Fig. 1 and also in TVLD 421). If the detected combination of speed then places the lift in the ‘Crash

TVL 294 ISSUE 3

12/06 27

Stop Area’ (suggesting a failure of the system to respond to the request to slow), the V-COM will drop its ‘OK’ relay, thus forcing a crash stop. As an additional backup to the methods described above, the ETHOS will consider, upon detection of BFR or TFR, whether it has requested slowing, via speed selection signals. If slowing has not been initiated, then the ETHOS will force a crash stop.

8.2 Testing Operation of the Emergency Terminal Slowdown facility may be tested by putting the lift out of step and then running the lift into a terminal floor, thus mimicking a failure to slow, as follows: Position the lift mid-shaft, at floor level, ensuring that the ‘DZ’ LED is illuminated. Switch the controller to TEST control. NOTE: Any attempt to carry out the following steps whilst on NORMAL control will result in the message “Unsafe To Accept Command”. Enter the V-COM Toolbox menu and select one of the following options:

ETSD Test Shift Up – this will shift the V-COM incremental lift position

up one floor from the current actual lift position to allow testing of the Emergency Terminal Slowdown facility into the bottom terminal floor.

ETSD Tst Shift Down – this will shift the V-COM incremental lift position down one floor from the current actual lift position to allow testing of the Emergency Terminal Slowdown facility into the top terminal floor.

The following screen will be displayed (example follows selection of “ETSD Test Shift Up”):-

V-COM ETSD Shift ********************* * You Are About To * * Force Position * * One Floor Up * * Are You Sure? Y/N * ********************* ��

Selecting “YES” will result in the modification of the V-COM incremental floor position, which can be confirmed on the main ETHOS status screen. Selecting “NO” will return to the V-COM Toolbox menu. Switch the controller back to NORMAL control and enter a call to the required terminal floor.

TVL 294 ISSUE 3

12/06 28

Example – Testing The ETSD Function Into The Top Terminal Floor With the lift positioned at floor 4 and ‘DZ’ LED illuminated, switch the controller to TEST control. Enter the V-COM Toolbox menu, select “ETSD Tst Shift Down” and confirm the selection on the confirmation screen. (Whilst the actual lift position is floor 4, the ETHOS and the V-COM Master (A) processor believe that the lift is at floor 3. The V-COM Slave (B) processor (if used), is, however, not affected by the position shift and, via feedback from the absolute encoder, and believes correctly that the lift is at floor 4.) Enter a call for the top terminal floor. As the lift approaches the terminal floor, the V-COM Slave (B) processor (if used) recognises that the speed of the lift is too high and will initiate emergency slowdown. If the V-COM Slave (B) processor is not used, the ETHOS will recognise, upon detection of TFR, that it has not initiated normal slowdown and will invoke a crash stop.
