7.1 ELEVATOR INSTALLATION
7.1 ELEVATOR INSTALLATION
1. The elevator must be in inspection mode.
2. DZ magnetic switches must be installed.
3. EOS UP and EOS DN must be installed at a distance of 1 m from last oor and rst oor respectively.
4. EOS UP1 and EOS DN1 must be installed at a distance of 1.5 m from last oor and rst oor
respectively.
5. Encoder must be connected to MicroZed v3.5 controller.
7.2 SETTINGS IN THE MAIN MENU
7.2 SETTINGS IN THE MAIN MENU
1. Set the “Drive” type to VVVF.
2. Set “Door Zone” to installed.
3. Set “VVVF Start Delay” and “VVVF/ Hyd Stop Delay” depending on the VVVF type used (“VVVF/ Hyd
Stop Delay” should be greater than time required to decelerate from high speed to zero and must always be
positive).
4. Set “Encoder” to installed.
5. Set “Pulses/Revolution”, “Roping”, “Machine speed m/s” and “Nominal RPM” to their appropriate
values.
6. Make sure that lift is going in the right direction (when inspection up, green led must be ON and
wheninspdn, red led must be ON). If not switch Up and DN direction outputs. Otherwise, switch encoder
signals.
7.3 LEARNING TRIP PROCEDURE
7.3 LEARNING TRIP PROCEDURE
1. Adjust the elevator at a position about 1m above EOS DN.
2. Set Dip switches 1 and 2 to ON.
3. Set the elevator to normal mode. The display will show “Must do a Learning trip”.
4. Enter to the menu and select “Learning trip”
, Select yes when “Are you sure?” message appears.
5. The controller starts learning trip at homing speed (Inspection speed).
6. At the end of learning trip procedure, the display will show the shortest DZ length calculated. The
user is prompted to accept or decline the calculated result.
7. If Accept is selected, the results are saved and the controller does a homing trip and stops on oor 0.
8. If Decline is selected, then the message “Must do a Learning trip” will reappear.
7.4 DISTANCE CALCULATION
1. Set the elevator to inspection mode.
2. Implement the necessary tuning on the VVVF drive to ensure close tracking of reference speed.
3. Adjust the position of the elevator on oor1 with DZ magnetic switch active.
4. Set Re-leveling to “Dist(mm) 10 “ if VVVF VX2 is used.
5. Set the elevator to normal mode.
6. Enter to the menu and select “Calc. HiSpd Distances “, Select yes when “Are you sure?” message
appears.
7. At the end of high speed distance calculation, the display will show the deceleration distance
traveled in the up
direction, the deceleration distance traveled in the down direction and the dierence, “d”, between those
two distances. ”d” should not be greater than 3mm.The user is prompted to accept or decline the calculated
results.
8. Select “Accept” to save the result.
9. Repeat from step 6 while selecting “Calc. IntSpd Distances “.
10. Repeat from step 6 while selecting “Calc. LoSpd Distances “. If re-leveling is enabled, both Lo and
re-leveling distances are calculated.
11. When all the 3 distances are calculated, do homing trip.
12. Adjust the position of EOS DN and EOS UP to “Int. SlowDown m” minus 5cm from oor0 and last oor
levels respectively (Not from DZ edge).
13. Adjust the position of EOS DNI and EOS UPI to “SlowDown dist. m” minus 5cm from oor0 and last
oor levels respectively (Not from DZ edge).
14. Set Dip switches 1 and 2 to o to activate hardware implementation EOS UP, EOS DN, EOS UP1 and
EOS DN1.
To do Learning trip, Collective type must not be set to MUL or MULF. Otherwise, the controller will prompt the user to change the collective type and will give this message ” Modify
collective type to Down or Full”
