Hoistway information

The installation is provided with two types of hoistway information: - Car hoistway information, where all the elements that detect the position of the car in the hoistway are located. - Hoistway information mounted on the car guide rail both at the top and bottom of the hoistway. Information in the car - Two magnetic sensors inform the door zone to the controller. If the installation has double entrance there would have to be two additional magnetic sensors. - Two optical sensors allow pre-opening of doors as well as re-levelling. Magnetic car sensors: The sensor is supplied with a 12 Vdc voltage and is threaded through a metal plate that drives the activation of the inner Reed bulb. The sensor should be centered when threaded through the plate. The magnetic sensors are called DZU and DZD.

Measurement 145 mm 275 290 mm

C: Door zone. Optical car sensors: The system has two optical sensors that indicate to the car it can perform leveling. These sensors are mounted so that when the car is located in the right zone, the beam of infrared light bounces and the light reaches the receiver. Emitter These sensors are called RLD and RLU. The optical sensors have two LEDs, one green indicating that the sensor has power and the other red indicating it is in front of a plate. Receiver When the metal plate is coated with a layer of black rubber, the light signal does not bounce, whereas if the plate does not have the rubber layer, the light signal does bounce. In the door zone, the plate is not coated, and therefore the light signal bounces.

Machine

The traction machine is a gearless machine with synchronous motor. The machine brakes are located inside the rotor, thereby reducing the space occupied by the machine as the brakes are not located on the outside of the stator, as is the case with other manufacturers.

Description Lubrication point. Machine absolute encoder Black rubber tube. Drainage tube (transparent) Drainage tube (transparent) Lubrication tank.

Description Remove the machine covers. Check that there is no grease in the drain pipes (transparent tubes). These tubes must not contain grease. If this is the case, there is the possibility that this grease has reached the brake mechanism and will thus reduces the braking force. Check the grease/oil tank located under the machine. Clean if necessary, as oil / grease may escape through the black rubber tube. When replacing the machine covers be careful that these do not press on the tubes.

Machine Maintenance

Machine lubrication The machine should be lubricated every two years; for this purpose, a grease pump and grease canister No. 25 from Mitsubitshi are required. After sending a request to the Mitsubitshi distributor (in Spain is Fain), the following product was sent: - Superplus Complex Tech grease. The amount of grease depends on the type of machine: PMF-3P7S/6 P5S 120 g PMF-011-S 200 g

Point 1 2 3 4 5

Description Open the machine cover. Remove the lubrication screw. Screw the grease pump in. Make a mark on the perimeter of the rotor. Enter 1/4 of the total amount of grease and turn the machine 180º. Repeat this four times to insert all the grease needed by the machine.

Machine Brake adjustment

To adjust the braking distance, the following tools are required: - Two dial indicator gauges. - Control panel for opening the brake individually. The two dial gauges are placed between the outer casing of the machine and the end of the core attracted by the coil. Anchor the car and open the brake coil with the tool for this purpose, and check that the brake release is: Machine Type PML-F037EB PML-F110EB PML-F065EB Gap measurement range Optimal measure

0.16 mm…0.20 mm 0.18 mm

0.19 mm…0.23 mm 0.21 mm

The brake KB contacts must only be adjusted in case of replacing the brake lining, otherwise there is usually no need to change them. Situation

Place the elevator in manual (HAND) and press the RUN and UP buttons from the HMI control panel which is located on the top floor. The motor attempts to move up (after 2 sec. pressing), but as the brake does not open a noise comes from the machine. After 5 sec. trying to move the machine test is completed. After 6 sec., the display of the HMI control panel a number is displayed. The decimal point of each display will indicate information. (The outside display also shows the number sequentially). In this example the number 80 is shown, not having any decimal point on any display.

In this example the number 167 is shown, with the decimal point of the display active (SEG1).

Rescue of Trapped Passengers

Step

Description

2

Turn the main switch to OFF. To do this turn the "MAIN SWITCH" key.

3

Turn on the hoistway lighting; to do this use the Light (EMR/HIP) switch

4

Turn the RSQ switch to ON.

5

To open the brake press the button BKD. Do not press for more than 2 seconds continuously.

6

The car will begin to move. The direction depends on the load in the car, as it moves due to system imbalance.

7

Check the movement of the car through a hole in the top of the top floor panel, via the recall control panel. From this hole it is possible to see the overspeed governor rope, which is painted yellow when the car is at floor level.

8

When the car arrives at floor level stop pressing the BKD button and proceed to rescue passengers from the car. Follow all safety instructions of the company.

9

If the car does not move when the button BKD is pressed, it is likely that the system is balanced and it must therefore be placed out of balance. To do this, add weight to the compensation chain. This weight is placed permanently in the pit of the installation, together with a set of hooks for hanging.

Once the weight is placed on the compensation chain, either in the car pulling or counterweight pulling area, depending on which direction we want to move the car, proceed to open the brake with the BKD button.

11

Once the car stops moving, if necessary, reposition the weights on the compensation chain to a higher level.

Rescue of Trapped Passengers

During normal operation the board supplying power to the brake is E1, together with P1. With the recall control panel, brake activation is only affected by the E1 circuit and not by P1. When in normal operation the brake does not open (no voltage on the 420 line); upon activating the RSQ switch, the voltage that activates the brake comes from PSR2, which is a line coming from the battery. If the general power fails (line 420) and the batteries are not in good condition, the brake can be powered by an external 48 Vdc source at the terminals located on the HMI botton panel behind the top floor landing operating panel. These cables are located at the bottom of the HMI control panel and the ends are covered with rubber stops to prevent them from touching the cover.
