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 “Velocity Pattern Interface” variant. Functionality is as below:-

Lift speeds up-to 6m/s. Re-levelling functionality. 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 offers a direct-to-floor approach. Where

system dynamics do not allow a consistent direct-to-floor approach, the V-COM can allow for a short corrective period at low speed prior to stopping.

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 12V 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. 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.

5.2.2 Parameter Definitions Parameter Description 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. During an approach into a floor, the VCOM will decelerate from Door Zone Speed to zero speed, when this overlap area is entered. (See also Section 7.5)

Speed Limit Allows the limiting of the maximum V-COM pattern output below Contract Speed, if required.

Contract Accel Sets the acceleration (and deceleration) rate, during normal running. The higher the acceleration rate, the shorter the inter-floor travel time at the expense of ride quality. (See TVLD 427)

Accel Jerk Rate Sets the rate at which acceleration/deceleration changes between stationary and moving or accel/decel and constant velocity conditions. (See TVLD 427) Higher values result in harsher transitions between these conditions.

Door Zone Speed Sets the target speed at which the lift will run during final approach to the target floor. (See TVLD 427)

Relevel Speed Sets the target speed at which relevelling will take place, when the lift is stopped and is detected as being outside of the leveller overlap area.

Relevel Accel Sets the acceleration (and deceleration) rate used when the lift is relevelling and also the deceleration rate from Door Zone Speed to zero speed during stopping.

Dive Speed * Sets the target speed at which the lift will run when seeking BFR or TFR in order to reset position.

Dive / Learn Accel. Sets the acceleration rate used during a dive (car seeking BFR or TFR in order to reset position) or shaft learn.

Dive / Learn Decel. * Sets the deceleration rate used during a dive (car seeking BFR or TFR in order to reset position) or shaft learn.

* Care should be taken when adjusting this parameter, as consideration may

need to be given to the positioning of BFR and TFR in order to maintain correct operation.

Parameter Description Test Speed Sets the target speed at which the lift will run under Test

Control. Test Accel Sets the acceleration rate used when running under Test

Control. Learn Speed Sets the target speed at which shaft learning will take

place. A lower Learn Speed will result in a longer time to carry out a shaft learn, but may result in increased accuracy in detecting the door zone vanes.

Emer Decel Sets the deceleration rate active during emergency deceleration. (See Section 8)

Contract Speed Sets the application contract speed. Pattern Delay Time Sets a delay before the pattern rises, and can be used to

allow for differences in the time taken for the brake to lift. Dwell Distance Sets the distance during which the lift will run at ‘Door

Zone Speed’. (See TVLD 427) Recom. LU/LD Overlap Gives a suggested value for ‘Leveller Overlap’ taking into

account the current values for ‘Door Zone Speed’ and ‘Relevel Accel’.

System Lag Time Sets a time delay used to compensate for the response of the drive/motor system to the output pattern reference. If too low a value is set, then the lift will tend to rush into floor with little or no travel at Door Zone speed. If to high a value is set, then the lift will tend to take longer to get into floor with increased travel at Door Zone speed.

ETSD Threshold 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, Fig. 1.)

Crash Stop Threshold 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, Fig. 2.)

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)

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 “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 “Encoder Data – ABS Encoder Pos. Dir.” menu.

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. NOTE: 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. (See NOTE above.) Following detection of BFR and the leading edge of the Bottom Terminal DZ, the ETHOS will stop the lift and after a short delay commence the “Up Learn”.

6.4 Learn Phase 1 Up Learn The lift will travel to the top floor, at learn speed, recording door zone edges and BFR / TFR positions. Following detection of TFR and the leading edge of the Top Terminal DZ, the ETHOS will stop the lift and after a short delay commence the “Down Learn”.

6.5 Learn Phase 2 Down Learn The lift will travel back down t the bottom floor, at learn speed, to confirm door zone and BFR / TFR positions. This second pass also eliminates hysteresis problems created by magnetic DZ sensors.

TVL 297 ISSUE 3

05/11 20

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 Pattern Profile Setup.

TVL 297 ISSUE 3

05/11 21

7 V-COM Pattern Profile 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 (see Section 6 – Shaft Learn Procedure) before proceeding.

7.2 Step 1 – Initial Running and Speed Scaling NOTE: Avoid running the lift to terminal floors at this stage. When commissioning a new installation, it is important to ensure that the speed is scaled correctly and that the System Lag Time parameter is initially set. Until this has been carried out with reasonable accuracy, changes to other running parameters may not have the correct effect on the running of the lift. Perform short runs to ensure that the lift accelerates and decelerates smoothly and attempts to slow into and stop at the target floor. Longer runs may then be carried out, limiting the speed achieved, if required, using “Pattern Speed Setts – Speed Limit”. Perform a long run, during which the lift could be expected to achieve contract speed. NOTE: “Pattern Speed Setts – Speed Limit” should now be set to the required contract speed. If the actual lift speed can be measured with a tacho., this can be compared with the value displayed on the “V-COM Status” screen. If any difference between the two speeds is appreciable, then check data set in the V-COM relating to the encoder. If the lift does not achieve the expected contract speed, then with reference to the appropriate LiftStore drive manual, adjust the pattern scaling parameter to achieve contract speed. Once the contract speed is correctly scaled, run the lift again and observe the amount of travel at door zone speed as the lift car stops at a floor. This should be compared with the distance set in parameter “Pattern Misc. Setts – Dwell Distance” If the distance travelled at door zone speed is significantly less, with the lift car rushing into floor, then increase “Pattern Misc. Setts – System Lag Time”. If the distance travelled at door zone speed is significantly more, then reduce “Pattern Misc. Setts – System Lag Time”.

TVL 297 ISSUE 3

05/11 22

7.3 Step 2 – Adjustment of Ride Quality Ride quality may be adjusted for comfort or performance using the “Pattern Speed Setts – Contract Accel” and “Pattern Speed Setts – Accel. Jerk Rate” parameters. Typical values are given in the table below:-

Rated Speed (m/s)

Acceleration (m/s2)

Jerk (m/s3)

<1.00 0.4 0.6 1.00 0.7 – 0.7 0.75 1.60 0.7 – 0.8 0.9 2.50 0.8 – 0.9 1.0 3.00 1.0 1.25 5.00 1.2 1.5 6.00 1.2 1.8

Typical Ride Quality Settings Taken from: CIBSE Guide D: Transportation systems in buildings - Section 3. Traffic planning and selection of lift equipment and performance - Table 2.5 Typical lift dynamics

7.4 Step 3 – Adjustment of Stopping Comfort and Accuracy [NOTE: Throughout this procedure, reference should be made to drawings

TVLD427 and TVLD422] The length of the up and down levelling vane overlap is adjustable to give a variable length floor level zone. When in the area of overlap the V-COM will ramp its output pattern to electrical zero under the influence of “Pattern Speed Setts – Re-Level Accel” and the lift controller will apply the brake and drop the running contactors.

A recommended initial setting for Leveller Overlap is calculated by the V-COM, taking into account the current setting of Door Zone Speed and Relevel Accel parameters. This value may be may be viewed in “Pattern Misc. Setts – Recom. LU/LD Overlap” and should initially be set in “Pattern Speed Setts – Leveller Overlap”.

Prior to any attempt being made to adjust Floor Level Trims it is essential that the lift stops consistently in both directions. A floor should be selected mid-shaft. With reference to drawing TVLD428, the lift should be run into the chosen floor from both directions and the stopping position relative to the floor level noted. The difference between the stopping positions (the “Stop Gap”) may then be used, as shown to set a value of Leveller Ovelap to compensate for the inconsistency in stopping. (NOTE: The car's position with respect to floor level isn't that important other than as a datum to measure the stop gap.) As an example, consider a stop gap of 10mm with the car stopping high in the up direction. For consistent stopping the Leveller Overlap should be increased by 10mm. This effectively brings the upward stopping point down 5mm and the downward stopping point up 5mm, which should result inconsistent stopping.

TVL 297 ISSUE 3

05/11 23

7.5 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. Example

Up Error (+/- mm)

Down Error

(+/- mm)

Average Floor Level Error

(mm)

Trim (+/- mm)

+10 +10 10 + 10 = 10 2 -10

-10 -10 (-10) + (-10) = -10 2 +10

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.

7.6 Step 6 – Saving Settings Once adjustment are complete, all settings can be backed up in the ETHOS “Memory Management” menu.

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 (B) processor.

8.1 Operation Figure 1 below shows the principle of operation.

EmergencyDecel. Area

Safe Area

Fig. 1: Illustration of V-COM Emergency Deceleration and crash Stop Scenarios The system defines three areas at each terminal floor: a Safe Area (in which the lift normally operates), an Emergency Decel. Area and a Crash Stop Area. The boundary between the ‘Safe Area’ and the ‘Emergency Decel Area’ is defined by an imaginary deceleration curve. This deceleration rate (set by ‘ETSD Threshold’ in the ‘Pattern Misc. Setts’ menu) would normally be set equal to the application deceleration rate (set by ‘Contract Accel.’ in the ‘Pattern Speed Setts.’ Menu), but extends 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. This deceleration rate (set by ‘Crash Stop Threshold’ in the ‘Pattern Misc. Setts’ menu) would normally be set to twice the application deceleration rate (set by ‘Contract Accel.’ in the ‘Pattern Speed Setts.’ Menu) and again extends from the trailing edge of the terminal floor door-zone.

TVL 297 ISSUE 3

05/11 28

8.1.1 V-COM Master Only The speed and position of the lift are constantly monitored by the V-COM Master (A) processor. 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 set by ‘Contract Accel.’ in the ‘Pattern Speed Setts.’ Menu). If the detected combination of speed then places the lift in the ‘Crash 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.

8.1.2 V-COM Master and V-COM Slave Where a secondary absolute positional feedback is available, the speed and position of the lift are additionally constantly monitored by the V-COM Slave (B) processor. Fig. 2 shows how the V-COM Slave (B) processor develops a pattern reference, which does not interfere with the pattern reference generated by the V-COM Master (A) processor, under normal conditions, but includes a limiting deceleration rate (set by ‘ETSD Threshold’ in the ‘Pattern Misc. Setts’ menu). If the detected combination of speed and position has placed the lift into the ‘Emergency Decel Area’ (as in 8.1.1), but the V-COM Slave (B) processor detects that emergency slowing via the V-COM Master (A) processor has not taken place, then the pattern reference will automatically be switched to that generated by the V-COM Slave (B) processor.

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”.

TVL 297 ISSUE 3

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. On software versions Ver2.32 and above, remove the DZ input plug so the V-COM does not see a DZ during the test. If this is left in the V-COM may produce a "Lost - Position Err" event and decelerate normally before reaching the ETSD Zone. If you see a "Lost - Position Err" event remove the DZ and try again. Switch the controller back to NORMAL control and enter a call to the required terminal floor.

NOTE: Where a satisfactory Emergency Terminal Slowdown cannot be achieved, the procedure above may be repeated, to place the lift further out of step.

TVL 297 ISSUE 3

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.

9.3 TFR/BFR Positioning The Top Floor Reset and Bottom Floor reset position switches are the primary position datum points. The switches should be rigidly mounted and operate cleanly. Excessive play or bounce on the switch or ramp could adversely affect V-COM operation. If either reset is moved a shaft learn should be performed (see Section 6 - Shaft Learn Procedure) in order to maintain optimum floor level accuracy and ride profile. If V-COM detects a large floor position error or following interruption of the power supply a dive sequence will be invoked and the lift will travel at dive speed to one or both terminal floors. During a dive or learn sequence operation of BFR or TFR will initiate deceleration the rate being determined by the parameter “Dive / Learn Decel”.
