Mitsubishi elevator PLC

Programmable controller are a stored program controlled device, the control function is achieved through the program stored in the memory, To make changes to the control function, in large part only need to change the software instructions can beso that the hardware and software technology. Increasing its position in industrial control, occupies an extremely important position, the most important reason is that it has the following unique characteristics of high reliability, easy to learn programming versatility, the system design cycle is short, the production process change adaptable, simple installation, commissioning, maintenance workload and adapt to the industrial environment. In short, the elevator control more complex, the use of programmable controllers for elevator control a vast space. mitsubishi elevator PLC is designed specifically for industrial process control equipment, with the application of mitsubishi elevator PLC technology continues to evolve, will make its volume greatly reduced, function continuously improved process control more stable and reliable. Strong anti-jamming performance, mechanical and electrical components organically combined in one device, instrumentation,electronics and computer functions combined. Therefore, it has become a key technology in the elevator running.

KONE elevator pcb LCE-KNX KM713130GO1

LCE-KNX unlock steps

Elevator Model: KONE 3000 MiniSpace

Control system: LCE-KNX KM713130GO1

Reason: KONE 3000 MonoSpace elevator run of 10,000 and above ,375-LCE-KNX

On the operation buttons are locked can not operate (in addition to selected within and outside the callback function), which will lead to

System parameters can not be set and change.

Objective: To unlock method to restore the normal function of the operation buttons on the 375-LCEEPU and run times

Number is reset to zero.

The electronic board :375-LCE-KNX method has been locked

1, 270 switch hit overhaul mode off the elevator main power

2, pull out LCE-KNX KM713130GO1 on D8 position NVRAM, replace a new NARAM

3, turn on the power

4 operation on LCEEPU button to enter the menu 1-99, the parameter is set to 2. Now

System parameters will revert to the EPROM default value (to do this operation, the elevator must be stopped at the end of

Layer, 77U, 61U must be valid)

5, operation on LCE-KNX KM713130GO1 button to enter the menu 5-7, the parameter is set to 1. Now

The elevator download (LON protocol elevator must be stopped at the bottom, 61U effective)

6, after the completion of the above steps must set the elevator hoistway self-learning. The elevator stopped at the bottom of

(61U), by operating on LCE-KNX button to enter the menu 5-2, the parameter settings

1, 270 after the switch to its normal position

7, LCE-KNX electronic board will beep twice

8, twice after the elevators will slow hoistway self-learning, until the top-level and more than the top floor flat layer

Position after parking, after the leveling position to return to the top level at LCE-KNX digital tube flashes about

Two seconds, and the beep indicates completion of the self-learning, LCE-KNX digital tube will be displayed at this time

Elevator floor (the floor number of floors for the elevator in the system, may be different from the actual number of floors,

Single floors over five meters in height, the the false floors need to set this in the setup menu.

Floors will play a role in the flag before setting these parameters, need to know that between the two layers

False floor)

9, after the learning is complete, the hit 270 switch maintenance position, the start parameter settings. Must be set

Parameters including menu elevator parameters, 3 floors flag. Specific settings based on the scene actual situation

Condition.

10, the parameters are set, the system must be powered off, wait for all the lights off, sending

Elevator lock and Elevator door lock

On every landing door and car door has a door electrical interlock contacts only when the sector-wide closed door electrical interlock linking point is closed, the door lock relay JMS pull the elevator to run.

The coupe and sedan are equipped with inspection switch and maintenance switch to overhaul bit the maintenance relay JM pull the elevator is inspected.

In the following four states, brake coil is energized, the brake open:

(1) Express upstream, that is, S ↑, K ↑.

(2) Express downlink, ie X ↑, K ↑.

(3) slow uplink, namely S ↑ M ↑.

(4) slow down, that is, X ↑ M ↑.

When the elevator starts to run, since the 1A, 2A is not yet energized, their normally closed contacts the RZ1 shorted, so DZZ able to 110V DC voltage, after a period of time after the elevator start delay, 1A energized, the resistor the RZ1 series to DZZ coil, DZZ ends voltage dropped to about 70V, called the sustain voltage. The role of the capacitor C8 is misoperation due to the the DZZ reduced from 110V voltage to the sustain voltage when there is a transition process, prevent DZZ voltage transients. Resistor RZ2 constituting the DZZ the discharge circuit.

In order to prevent the elevator from Express K converted to idle M, DZZ a power of the moment, so into the JK-delay relay, thus ensuring the operation of the brake does not occur twice.

When the elevator up contactor S or downstream contactor X suck timely to run relay JYT pull said elevator being run.

Acceleration and deceleration delay relay

When drivers press the button to start closing through of JYT 1JQ, so J1SA pull when through R1SA to capacitance C1SA charge when the elevator began to run, JYT ↓, J1SA did not immediately release, C1SA by R1SA of J1SA discharge , to make J1SA still suck together for some time, so J1SA delay the release of the relay. When released J1SA, an accelerated contactor 1A pull the elevator start after the buck to an accelerated into steady speed express train state (see run loop).

Elevator in the express run state, J2SA, J3SA, J4SA in suction engagement state, once transferred the slow M ↑ → J2SA delayed release → 2A ↑ → J3SA delayed release → 3A ↑ → J4SA delayed release →. 4A now ↑ the formation of 1, 2, 3 deceleration.
