Weak current College】 【Mitsubishi common failures and resource collection (4) --- Power By】 【China power house network.

<br> Door panels have a problem ...?< br> Door Board adopts voltage speed control for 3 phase control, and close the door after one of decompression phase through resistance continued to maintain a small torque to prevent the door was open, .this is the Mitsubishi spvf ladder runtime always closes the signal output, but also because this door plate permanent jobs, to door machine board electronic devices require a high level, door position signal through a grating plate to sampling. Grating plate position is very important, .although it seems to be dead, or you can fine tune, in short, in the course of the switch, you must see the LED lights-off-off-off-off process, otherwise the elevator door looks normal, real in Terminal motor .also then run for a long time, door panels will be ruined. Door Board unless the full intake can no longer use, or a good repair, see the Red modules, usually this thing doesn't work, he is ok. <br> .<br> A run is self-insured ...?< br> General elevator has a fault inspection system, a run on only the fault itself at run time before it was checked out, such as elevator overcurrent, coder no output, drag .the data do not match, and so on, because the earlier elevator cannot memory fault, so each time after power failure occurred a run is self-insured. On this failure, we'll find a captive insurance reasons, in the absence of maintenance .machines, we first look at the encoder, the output of the encoder in motor rotation is 2.5v AC, stopped the voltage should be less than 1VDC, no problem if the encoder, external wiring is normal and may cause overcurrent, the outputs may be .really over current, such as motor over-current, Elevator overload, current detection unit (dc-ct). In E1 Board we can detect the ct of bias, if it is not, you need to adjust the OFS potentiometer dc-ct, .how to adjust the SPVF installation manual records. <br> <br> Half open door ... again? <br> This is a very simple question, is listed here, because this kind of failure frequency is too high, General door safety .edge connector because the door is often broken or short circuit the games, such as door movement safety edge connection when broken when pass because making solid door off the part and open. <br> <br> Write to a floor indicates not blinking .. ..? <br> In debugging and maintenance we often have to write the floor height, actually writes the number of floor impulse, deceleration point location. If you write floor indicates no blinking or flashing stop flashing after the data is not entered, this usually .is due to the Mun signal and forced reduction is not working properly, one-way forced deceleration signals have forced floor 1, Mun is the key to great sampling floors, some overseas Mitsubishi Mun signal 2, a push for relay, a type of computer ., do not see the DZ relay or computer Board of DZ lights that Mun signals properly. <br> Nine. GPS-2 How to cancel within a layer of elevators? <br> Solution: change the CC2 <br> <br> X .. a Mitsubishi sp-vv (A) the elevator, functioning properly, sometimes flat layer back door driving only 10-30 cm, then the floor indicates flashing, stop, power PLC scanning back can sometimes last for a few days can only be used .for a few hours recently more and more frequently. does the fault the master is there problem Ah?? Other: sometimes 1DV display fault 35 what is the meaning of? there is a problem with the encoder? <br> Workaround: display 35, .is running behind the set speed. <br> You put the encoder shell it down, use a soft cloth notes, it is best to change my coder, but very few of the encoder in West Germany. <br> There is no scan PLC ., is the inner self. <br> <br> 11. the failure of two GPS-3 somewhat like you, I is two parallel which one occurs every three layer automatically quite a ladder, basement and no one will own creatures, to independent .does not show every outbound / f, soon to Flash a bit like a fan red light, in the end we have failed the parallel communication cable pulled from Groove to and swap it Jack no faults, we now suspect that may be the line out of .the question <br> <br> 12. a Mitsubishi SPVF elevator door not occurred (cannot open or shut, but door motor with power pass, just can't), control cabinet for door signal, manually close the door after the elevator to .go ladder, check the door motor third root line voltage respectively 56, 28, 28, door machine knife switch voltage-105 <br> Solution: fault attributable to the control cabinet have a socket in a thread not good (PIN), is the .UK socket <br> <br> 13. Mitsubishi SPVV-A elevator, recently appeared on days of recoil. Trouble phenomenon: the elevator 10 layers, 1.75m / s. I have registration room observation and 7 floors and 10 floor, lift up .display 1 / f, unchanged until the recoil is displayed as 10 floor. <br> Solution: this failure is due to the encoder encoder caused by dust on the <br> <br> 14. a GPS-II elevator, when the elevator .up to the speed of each layer, the motor will give "OM" in a very nasty. especially reach the top floor of a more serious is normal, the downlink. <br> Solution: the worm in a bearing is broken, with the .naked eye cannot see, only changed a try to know the elevator traction machine has four bearings, couplings, next to the bad, and the model is 6311Z. <br> <br> <br> <br> <br> <br> .15. Mitsubishi GPS-2 (EF-cannot restart) panic fault, Elevator random floors flat layer position, no floor displays, cannot call in, sedan lights fan radio, control screen failure code (EF-cannot restart), safety circuits, weighing .device, parallel, room temperature and heat dissipation are normal, the failures have occurred in the middle of the morning less elevator usage, fault frequencies 1-2 times a day, press the emergency stop or maintenance after reset normal use for a period of time ., sometimes panic after La electric transmission continuous panic <br> Solution: check forLeveling sensors bad <br> <br> 16. Mitsubishi HOPE fault for help, HOPE a Mitsubishi elevator car lighting does not shine, LCM pick-up, if not pick .-up, relays LCM elevator car illumination light, inspection line, no problem hasn't been investigated and dealt with the problem <br> Solution: the door panels of the Hibernate feature problems. don't relay line so that it is received by .it but not why. hibernation. heat exchanger plates! that often the fault <br> <br> 17. <br> <br> Mitsubishi Mitsubishi elevator is GPS in recent years, mainstream products, launched a gps respectively, gps-2, .gps-cr, gps-3 ... <br> <br> Dov <br> Main loop belt lights <br> <br> 29 <br> Safety circuit <br> <br> 89 <br> Automatically or run < .br> <br> Dz <br> Mun led <br> <br> 41dg <br> Door shut down lights <br> <br> 60 <br> Automatic status <br> <br> Pp <br> Phase (acr .) lamp <br> <br> Up <br> On the run <br> <br> Dn <br> Next run <br> <br> 21 <br> Door instructions <br> <br> 22 <br> Closing .instruction <br> <br> Dwdt <br> Deputy computer running <br> <br> Cwdt <br> Primary computer running <br> <br> 1.Stuageempty no failure: no fault occurs to the display when you show it. .2.A-NEG <A-MAXDECELERATING/A-NEG determine scope than INSTALLATION / A-MAX given scope small .3.

Mitsubishi SP-VF calls for help, I have a computer in the normal elevator broken. all are bright in the selected button, walk to .lifts layer with a layer of stops, just keep the layers and bright, the elevator is duplicate go <br> Solution: put the cabin manipulation disk moved to room try there is no problem, everything is normal, I set the plate in the back .of the car in all normal problem solved. It is estimated that the cabin manipulation disk serial interface has had a bad contact. <br> <br> 19. Mitsubishi crane soBarrier for help, a Mitsubishi SPVF elevator door not occurred (cannot open or .shut, but door motor with power pass, just can't), control cabinet for door signal, manually close the door after the elevator to go ladder, check the door motor third root line voltage respectively 56, 28, 28, door machine knife .switch voltage-105, door panels and other ladder on changed, plate is good <br> Solution: check the details later, found the door phase. <br> <br> 20. Mitsubishi GPS-II fault for help, I have a .Mitsubishi GPS-II elevator, symptom is: lift running process has stopped, and then auto-leveling, found P1 Panel SWDT led is not lit, and then lift will not be able to run. New automatic transmission, the elevator, elevator after written .procedures have been properly <br> Solution: replace P1 plate after the return to normal. <br> <br> 21. Mitsubishi SPVL resort, an 18-storey station SPVL elevator recently always ordinary burnt high-power transistor, the temperature is good ., driver Board also changed a few, large capacitance is replaced, the elevator runs for several days or in the case <br> Solution: replace the E1 Board after normal. <br> <br> 22. Mitsubishi SP-VF fault for help ., seek help Mitsubishi SP-VF elevator 3 layer 3 station. A failed State. Elevator stopped on the first floor but uneven floors high. Do not display. The safety circuit is switched on, the car immediately issued within the room displays overload 1 / .f, flashing. The elevator is not going away. <br> Workaround: is safety relays. There is a belt wear Portal crane of the back door. Great burn burning smell. <br> <br> 23. a Mitsubishi VVVF lift original .normal, from the beginning of March this year, often running suddenly stopped, and in the event of a failure even layer station display off, the normal cabin lighting, General five-or six-day happens once such failures, failure of the elevator position .is no direction on the law, and no regular running, check for power supply and power supply cable and replaced, in accordance with the debug switch for measuring various voltages are outline meets requirements, safety circuit also normal, the fault has been resolved. < .br> Solution: put P1E1W1 plate output pins are hot again until now has not repeated the fault. <br> <br> <br> 24. the door asking GPS_2 one GPS_2 elevator door machine, switch speed adjusted after running a few times or .lock staircase and then open staircase you door <br> Speed change, how can't fix <br> Workaround: car door lock switch and photoelectric switch action distance respectively 9, 5 <br> <br> 25. a Mitsubishi GPS-2 .passenger elevator, total 32 floors 1 to 5 floor building with no stops in the Middle, there are two access door, lift in the course of normal use, the user reaction sometimes run in 6/f-7 floor, Elevator suddenly stopped, then .the leveling to 1 / f, then all is well, sometimes in 7 floor or floor 8 and above, the nearest flat layer, all in a day, probably about 6 pm, a time, door locks, switches, access door switch, croquet ., door, security loop multi knife checked, P1 and door panels have changed, and the fault still, user comments, note that this site has three parallel ladder, there is a problem on this computer, you should exclude 380V power problems <br> .Solution: the problem has been solved, redo the weighing, these days there is no fault found! <br> <br> 26. <br> Hope of elevator operation time elevator suddenly stopped, the cause of the failure: no display, would .amount to the sedan led is not lit, press the key is not working, room seven-segment digital display EB to sedan transmission errors. I only know through multi-party Snoop is sedan SBC-C chip has the problem, replace the normal later .. <br> <br> Symptom: elevator control cabinet overhaul uplink elevator won't drive / service center <br> Acme Mitsubishi sp-vf <br> Analysis by overhauling the uplink control circuit diagram 2-20 we can see that automatically places .a maintenance and repair of relay 60, DS diode is damaged, or the up button UP press is not in place or is damaged, 89 relay does not work, the main contactor and brake contactors LB shall not electricity, Elevator does not start. < .br> Exclude method checks TB24 have + 125V voltage, 89 safety circuit relay coil ends no voltage on the circuit there are failures. Powered by measurement resistance gear 60 relay normally closed point correctly, the up button is pressed on the two contacts, of suspected .DS diode is damaged. Multimeter resistance measurement diodes open stalls, replace the protection diode DS after 89, the relay, press the up button, Elevator maintenance function to move the uplink. <br> <br> <br> Trouble phenomenon: the elevator .car top shooting upward lift won't drive / service center <br> If auto-repair switch or move up button to contact is not good, will make the elevator did not drive. <br> Exclude method automatically-maintenance switch reset overhaul, .press the up button UP, another one in the engine room watch D89 lit, found D89 always is not lit, the 89 relay circuit faulty. Check car top junction box line normal, automatic-maintenance switch, button switch properly. To the engine room .to check 89 relays not loose, measuring coil normal phenomenon without open circuit. Finally the W1 onboard terminal block to tighten up, plug, and then again press the power to move up to normal. Note 89 relay-W1 Board conductors-contact loose access .to undesirable phenomena. <br> <br> <br> Symptom: lift any State do not open the door, not closed / service center <br> Acme Mitsubishi sp-vf <br> Analysis of elevator in automatic and maintenance of State will .not be able to switch on the switch motor control circuit of the main loop, may have a problem. The Mitsubishi elevator door motor for three-phase AC 110V, if power supply transformer 110V output without damage, door motor nor the action. Switch signal .is W1 W1 plate control, if no output switch signals, of course, do not switch on the door. <br> Exclude method to check the power supply 110V correctly, confirm that the door motor three-winding symmetric, door motor fault-free .. Manual contactor action, contact the primary contact is good. Last doubt there may be a failure of the thermal relay, observation of thermal relay is indeed too, before the action is not reset, PC-W1 got a thermal relay signal, any State .do not close the door. May be the occasional overcurrent, door engine heat relay. The thermal relay reset switch to normal <br> <br> <br> Trouble phenomenon: the elevator in the end station away from floor leveling accuracy difference / Service .Center <br> Acme Mitsubishi sp-vf <br> Cause analysis SP-VF Mitsubishi in upper and lower end station is by the forced change-speed switch control, leveling accuracy good instructions to install the correct gear switch position, the slow speed mode .correctly. But the middle layers of wrap speed reducer point by microcomputer combination rotary encoder simulation elevator. Simulation of the elevator in the elevator when the actual start-up, than one step ahead of the actual lift (for an amount in advance), its .purpose is to detect where the target layer, ie, to have to answer the floor first stop, the lift to the simulation to layer stop, the lift will issue a deceleration signals, press the slow mode speed to the layer, the layer switch signal .PAD, the elevator down leveling. So the end station outside of intermediate layers leveling accuracy determines computer to simulate the elevator to the amount of time in advance and the deceleration rate mode correct or not, which is equivalent to the elevator before leveling of deceleration point .position accuracy. <br> Exclude method like this failure is a microcomputer software debugging problems. Manufacturer software debugging staff to modify debug analog elevator advance amount ahead of time and the deceleration rate mode can be resolved. <br> <br> <br> .Symptom: sedan maintenance uplink elevator not running / Service Center <br> Acme Mitsubishi sp-vf <br> Causes of car repair, auto-repair switch reset "overhaul" the 60 relay disconnection, 89 security circuit relay disconnection, Elevator does not automatically .start, due to the loss of control of the computer, is in manual to move the running state. 89 safety circuit relay implementation by pointing to the electric, LB brake contactors and the main contactor have electricity, move towards the elevator runs. Sedan service .is sedan maintenance uplink button pressed, 89, the relay have to power to move up the elevator. If this point moving upstream circuit car top uplink button, DS diode components, 89 relay any point failure will not be able to achieve the point moving upward .. Uplink direction signal by SSU control, if the direction control circuit failure, that is, press the UP button, SSU point has not been high potentials, nor can achieve up to move the function. <br> Exclude method checks the measurement sedan maintenance .uplink button UP, diode component DS are conduction, 89, the relay is also trouble-free. Direction control circuit-s components on trouble-free. So where is the fault occur? suspected jiaoding overhaul switch is not reset in "automatic" status ., maintenance personnel have just from car top on it. Sedan top check, it really was the car top auto-repair switch also placed in the "maintenance" status. The figure shows, the sedan maintenance circuit not + control power 125V, so it .is not possible to move up. The car top auto-repair switch reset "automatic" position, the sedan maintenance uplink run correctly. Such failures should be taught, done must be restored. For example, when troubleshooting sometimes short circuit, then verify that .there is no fault, however, must not forget to remove the short wiring in a timely manner, this will cause big loss and major accidents. <br> <br> <br> Trouble phenomenon: the elevator there was three-phase power supply .normal phase protection / service center <br> Acme Mitsubishi sp-vf <br> Cause analysis from Figure 2-24-phase protection circuitry to look different from other elevator forms. From transformer TR01 and three-phase AC 100V TR02 ¡ .ú ¡ .ú three-phase rectifier R-ACR → + 125V (79-00). + 125V power value reflects whether the phase-phase power supply, by the electronic circuit board to monitor the E1, when any deficiency phase when + 125V greatly reduced. .E1 electronic board to issue computer logic operations, a lack of trust, the motor may not start to run. Any point in the circuit failure, will produce an error signal deficiency. <br> Exclude method by checking the correct power into line, + .380 also correctly, confirm 125V is + 125V during transmission, the breakpoint will VA-03, UA-03, UB-10 plugs are plug a, feel reboot after docking firmly, Elevator run normal power supply. <br> <br> Symptom .: safety switches are in the normal position, and the safety circuit relay not electric, elevator not starting / Service Center <br> Acme Mitsubishi sp-vf <br> Cause analysis as in Figure 2-19 shows, although well road within the safety .switch is functioning, but the automatic maintenance work or damage to the relay is not, or no power, 60 normally open point, 89 safety circuit relay will not work. <br> Exclude method check and repair a 60 automatic relay does not have electricity ., but is actually a very small faults, because just finished, control cabinet and repair overhaul relay forgot to put the "automatic" in a timely manner, of course, does not have to relay 60, 89, the relay will not work. The .control cabinet overhaul relay "automatic" bit, fault also disappeared, sometimes because the work itself, is not a fault, human-caused by wrong operation breakdown, this phenomenon is that need attention. <br> <br> <br> <br .>.
