First, conduct on-site electrical line inspection.
1. Inspection state test run
A car interior maintenance:
1 Check if the setting parameters of the review inverter meet the requirements.
2 Put the inspection switch in the inspection state in the car. Then do not leave people in the car, but operate on the control panel of the computer room.
3 At this time, the PC input point X7 is on, and the X10 is off for trial operation in the car.
4 The interior of the car can be short-circuited with the internal command input point of the 11L14 high-rise station.
5 Car interior maintenance downlink can be shorted with 11L40 and the lowest command station internal command input point.
B Car top overhaul: At this time, X7.X10 is not bright, and the car top can be used for trial operation.
1. Car top maintenance upside 11L40 and 21L6 short circuit [X11 bright]
2 . The car top maintenance downlink 11L40 and 21L7 are shorted. [X12 bright].
3 Inspection and operation of the elevator state; when 11L40 and slow up or slow down, the elevator should immediately close the door [PC out point Y3. GMJ
Up; SJ up or XJ up]. When the door is completely closed [Y3 goes out; GMJ goes down. Y14 or Y15
`Y12`Y0 bright]. The elevator immediately starts up or down. At this point, observe whether the elevator running direction is consistent with your command direction; if not, change the set value [0/1] of the inverter LF5; until the running direction of the elevator is consistent with your command direction. At the same time, it is necessary to observe whether the directions [+ and -] of the inverter parameters LF88 and LF89 are the same. If not, change the setting value [on/off] of the inverter LF18. Until the two directions are the same.
4. The inspection state should be opened immediately after the operation stops.
5. Please note that due to the first operation of the elevator, the situation of the hoistway is unclear, and it is feared that the car will collide with the hoistway.
6. After the engine room test and maintenance operation is normal, you can enter the car top operation.
C. Car top operation;
1. Check that all switches on each car top safety circuit are valid.
2. Check if the car top inspection is prioritized.
3. After the first and second items are normal, you can press the car top up or down button to perform the car top inspection operation. If it is not normal, check the car top after an emergency stop.
4. If the car top inspection point is up and down, it is normal. The whole process of the hoistway can be inspected on the top of the car. Check that the hoistway is installed correctly.
D. The measurement layer is high.
1. The elevator is at the lowest level and is in a normal state.
2. Turn the plc operation switch OFF, use MHP to turn M812 ON; M811, M510 turn OFF, M150 turns ON [M150 is the high level switch, M510 is automatic, M811 is decelerated under M812) C235 is cleared.
3. The PLC and RUN switches are turned ON. At this time, the elevator will automatically close the door, and the inspection speed will go up. When it reaches the top layer, it will automatically stop. At this point, the height measurement work is over. And Z=2n [n is the number of landings]; D250=n is monitored. Use the programmer to monitor whether the M510 is NO. If no, the height measurement fails, and the above work should be redone.
4. Note; the value of DD202~DD[200+2n] recorded by PLC is the layer height meter, which can be used for future maintenance. It is not allowed to arbitrarily change the value of the inner height of the PC.
5. Use the car to overhaul freely up or down, whether the change of the number of the floor is correct and from the bottom to the top, and from the top to the bottom, the view floor is digital, if correct, you can try the express train.
2. Leveling accuracy adjustment
1. When each layer is flattened above and below;
a. When the underlevel is below 50mm, the upstream can reduce the value of DD274, and the lower limit can reduce the value of DD276.
b. When the super-flat layer is below 50mm, the value of DD274 can be increased in the uplink, and the value of DD276 can be increased in the downlink.
c. When the 3rd floor is not leveled and the 3rd floor is leveled, the leveling error is 20mm.
d. Move the magnetic shield on the 3rd floor to 20mm.
e. Increase the value of the memory DD206 in the layer height table corresponding to the 3rd floor corresponding to the pulse number of 20mm distance.
f. The value of the PC data register DD358 is how many pulses per mm, so the pulse number PI of 20mm is;
g. PI=20╳DD358
h. Set DD206=P measured at the original height, then the new DD206=P+P1.
i. If the 3rd floor is super-flat, and the 3rd floor is under-level, the leveling error is 20mm.
j. Move the magnetic shield on the 3rd floor down 20mm.
k. Reduce the value of the memory DD206 corresponding to the floor height table corresponding to the 3rd floor corresponding to the number of pulses of 20mm distance. If the measured height is DD206=P, then DD206=P-P1 should be adjusted. Before the high, we must patiently adjust the flat magnetic separator of each layer;
l. Ensure that the magnetic isolation plate is adjusted when it is completely level.
m. The installation position of the magnetic isolation board should be accurate.
n. In addition, when it is found that the leveling layer is not ideal, first check whether the elevator has enough crawling sections, whether the grounding is good, whether the rotary encoder line laying meets the requirements, and do not rush to adjust the leveling parameters and the magnetic isolation board.
3. Automatic status
1. Set the automatic [no driver] switch to the automatic state [X25 bright, M16 ↓], check whether the selection, operation, deceleration, and elimination of the external call signals of each floor are normal. If it is not normal, it should be found whether the hoistway wiring is wrong [because the control panel has passed the in-plant inspection test].
2. When it is necessary to measure the insulation resistance, all the leads of the inverter [including all control lines and main circuit large lines] should be recorded and then removed, and the input end of the PC should be pulled out of the PC main body in whole row. Conduct insulation tests on various terminals to prevent damage to the inverter and PC input.
Test run self-rescue function and fire function
A. Self-rescue operation function;
The test method is to let the elevator run normally after leaving the door zone, that is, X4↑, press the emergency stop switch to stop it, and reset the emergency stop switch. At this time, M99↑. If the elevator stops at the 1st or 2nd floor, select the upstream M61↑; if the elevator is on the 3rd or 3rd floor, select the downstream M62↑. At the same time, after M99, after 4 seconds delay, T48↑, M100↑, Y14↑ or Y15↑, Y12↑, Y0↑, the elevator enters self-rescue operation [Y27↑ during self-rescue operation, buzzer sounds], so that the elevator enters Open the door X4↓, the elevator can stop and open the door.
B. Test of the fire protection function of the elevator;
1. Fire return test; [M66 消防 when fire returns]
1] The elevator is put into fire when the base station closes the door; the door should be opened immediately, and the door is opened after M66↓, M166↑.
2] When the elevator is opened and the door stops at the base station, it is put into fire; that is, M66↓, M166↑.
3] The elevator is put into fire when it is not entering the deceleration; it should not open the door after decelerating to the nearest station, and immediately start to return to the base station, return to the base station and stop driving after opening the door M66↓, M166↑.
4] The elevator is put into fire when it is going up into the deceleration; after deceleration, it does not open the door, but starts to return to the base station, and stops to open the door M66↓, M166↑.
5] The elevator stops when the non-base station is not closed. It should be turned off immediately after the door is closed. After stopping the door, M66↓, M166↑.
6] The elevator stops when the non-base station has closed the door and puts into fire; it should start to return to the base station immediately, and open the door after M66↓, M166↑.
7] When the elevator does not enter the deceleration, it will be put into fire; it should be returned to the base station without deceleration, and M66↓M166↑ after parking and opening.
8] When the elevator has entered the deceleration, it will be put into fire; it should not be opened after deceleration and stop, and start to return to the base station M66↓, M166↑.
9] After the fire is put into the fire return status, all internal and external call signals are cleared.
2. Fire control test; [M66↓, M166↑ during fire control]
1] Only the internal command is valid, and the internal command cannot be self-sustained before running, and the outgoing call signal is invalid.
2] In the base station, the internal command can close the door, but before the operation, the internal command button is released, and it is required to close the door immediately [ie, the door cannot be self-maintained].
3] The instruction is completely canceled every time the parking is stopped [ie, the most recent internal command is valid].
4] When parking at a non-base station, the door cannot be opened automatically, and the door can only be opened by jog. When the door open button is released, the door should be stopped immediately, and the door will be closed automatically and automatically [closed door requires self-protection, but the safety touch plate and overload are still valid].
5. If the upper and lower stations are always super-flat in normal driving, it is likely that the upper limit switch installation position is too low or the lower limit switch installation position is too high. Please note that the installation location is correct.
