If replacing a motor encoder on a permanent magnet machine (i.e Endat encoder) then ropes will have to be lifted and a rotational auto-tune will be required. When replacing an incremental encoder on an induction motor a static auto-tune would in most cases be sufficient.

Please refer to job contract manual for relevant auto-tune procedure.

1. Changes to drive parameters must be manually saved otherwise they will be lost after power-down.
2. Navigate to the beginning of any menu which will have a number followed by 00 i.e 1.00 or 2.00.
3. Press ‘M’ until the cursor flashes on the value (which will be 0).
4. Using the keypad change this 0 to 1000 and press M followed by the red reset button. The 1000 will then change back to 0. This indicates that the parameters have been saved. If the value of 1000 does not change back to 0 then the save has not been successful, repeat the process. To confirm parameters have saved, power down the drive i.e turn off mains isolator, UPS if fitted and disconnect any backup batteries. Then reinstate the supply and check the last parameter edited.

Note: DO NOT change parameter 0.48 or 11.31 as this will default the drive parameter file.

• Set parameter 3.24 to 1
• Set parameter 3.40 to 0

In order to return the drive mode back to ‘closed loop’ set the following parameters.

• Set parameter 3.24 to 0
• Set parameter 3.40 to 1

These are hardware faults, drive must be removed. Please contact TVC to discuss options for replacement.

Please refer to relevant contract manual for full description of these trips but here are some common causes.

Check the following:

• Brake is lifting correctly. (Check Brake and Brake Circuit).
• Lubricate car/counterweight guides.
• Check for stiction in car/counterweight guides.
• Check motor encoder wiring.
• Possible faulty motor encoder.
• Excessive Accel/Decel rates.
• Check motor encoder coupling.

1. Check Brake Apply Delay #D05 Is Not Set To Zero (Default 500ms)

1. Check Drive Current #J22 Is Not Above motor rated current #B02
2. Check #B16 Is Set to Maximum

1. The Error is Between Profile Speed #J39 & Actual Speed #J40.  Check Gains i01 i02 Starting Gains, i06 & i07 Running Gains, Distance Error Can be monitored in #J56
2. Check encoder is in Feedback Mode #C14
3. This could also be a balance issue

1. Check #F27 is set back to D03

1.  If replacing a Motor Encoder on a Permanent Magnet Machine (i.e Endat Encoder) we would recommend a rotational autotune is carried out. However, a Static tune can also be carried out, but it is advisable to do it 3 consecutive times. Making sure the learnt Phase Angle C.13 on each attempt come backs with a value less a couple degrees deviation.
2. When replacing an Incremental Encoder on an Induction Motor a Static Auto-Tune would in most cases be enough. Please refer to job contract manual for relevant auto-tune procedure.

1. Change parameter C.14 from Feedback to Sensorless (Do Not Change The Control Mode To Open Loop A.02 or B.01).
2. Change parameter C.21 Bit 0 (First Bit on Right) from 1 to 0. This will disable the Encoder Wire Break Detection. If left enabled the drive will report an Encoder 2 trip error.
3. It’s important an Autotune is carried to optimise motor control prior to running the lift on Test.
4. The parameter changed should be saved, however they will need to be set back to TVC default values once the encoder is fitted

1. Changes to drive parameters must be manually saved otherwise they will be lost after power down
2. Navigate to the beginning of any menu which will have a letter followed by 00 i.e A.00 or E.00
3. Press ENTER (button above Red button) until the cursor flashes on 00
4. Using the keypad Navigate UP and select SAVE PARAMETERS then press ENTER, followed by the Red Reset Button. The text SAVE PARAMETER will then change back to 0. This indicates that the parameters have been saved. To confirm parameters have saved, power down the drive i.e turn off mains isolator, UPS if fitted and disconnect any backup batteries. Then reinstate the supply and check the last parameter edited.

2. Check Magnet alignment and Tapehead Guide Shoe for wear.
3. Check Trailing Cable and replace were necessary.
4. Consecutive attempts at relevelling can also generate this event, if the processor does not see the magnets in the correct sequence. Check Valve block and Oil temperature.
5. Possible Hardware Fault with Processor Consult TVC Support Customer Service.

Check the limit has been reset. The lift should be returned to the bottom floor. Then check the processor is seeing LU LD DZ and TFR (BFR should be off if limit is normally closed). The processor should now acknowledge the ECS button and clear down event.

Default Pin code is 0000 (Master Pin code 6595)

Check the processor is seeing DOL or DCL. If not check the 110vac control circuit MS feed.

Possible processor EMC noise spike ensure all contactor/relay coils and 3 phase door motor windings are suitably suppressed as per contract drawings. Also ensure the control panel has adequate earth bonding.

Check 5vdc power supply. This supply must be a minimum of 5 vdc under load. If this cannot be achieved with the existing power supply, then a replacement 5v PSU can be purchased from TVC.

Take the lift to the Main Floor and cycle door.

Refer to contract drawings, a site visit by TVC can be carried out to investigate, contact TVC for further advice.

Ensure all contactors/relay coils have suitable suppressors fitted as per site drawings. Check and improve earth bonding continuity throughout installation.

Switch off mains supply, remove all processor board and clean PCB edge connectors with suitable electrical contact cleaner before firmly re-inserting them.

If this fails to rectify the issue then a site visit by TVC is recommended to investigate.

1. . Check M6808 PSU supplies are outputting the correct voltage.
2. Switch off mains supply, remove all processor board and clean PCB edge connectors with suitable electrical contact cleaning fluid before firmly re-inserting them. If the loop LED is still not looping/flashing following this action then it likely there is a board fault. Contact TVC customer support for further advice.

ON RECEIPT OF THE UPS

· Please check for damage. Please inform TVC of any damage is found.

· This is to be fitted in a clean dry and dust proof location.

PLEASE NOTE

• The UPS must have 300mm clear space behind the ups exhaust port (fan) for ventilation.
• The dry contact card should be configured and wired as per TVC diagram and slotted in to the expansion slot on the rear of ups. Also check R.E.P.O jumper is fitted to rear of UPS (remote emergency power off )Please check range of ups as not fitted to all (default off , as set by manufacturer).
• UPS wiring should be of a suitable type and be rated to the same size cable as the TVC mains and motor wiring in the panel. Suitable glands should be fitted to protect cable entry into the UPS .Isolate mains supply and UPS supply and verify before any works are carried out.
• Mains isolator should be checked for an additional pole to disable ups auto rescue when mains isolator is manually switched off.
• Before powering on UPS the wiring should be checked that the terminals are wired correctly, US1,US2, US3 for input and US4,US5,US6 for output . If wired incorrectly this will damage the UPS.
