MA - AZ 2 (E)

1.) Application

The following assembly instructions serve the purpose of replacing seals and spare parts on existing elevator systems.

2.) Structure

The drawings are structured so that a clear distinction is made between components and individual parts.

The assembly drawings of the components are included after the overall drawing of the valve. Various components such as the start-up and lowering valve pistons are not mentioned because they must be assembled using special tools and can therefore only be obtained as a complete component ex factory.

For all tasks performed on valves ready for operation, the items included in the chapter Safety instructions must be observed

3.) Fundamentals

- All assembly tasks must be carried out with the system shut down and depressurised. - It is important to make that only original ALGI spare parts or seals are used.

- The assembly tasks must only be carried out using suitable tools. - Dust and dirt must be kept away from the opened valve in any case. - Following the assembly tasks, the valve must be bled of air as follows:

- Open the ball-type shutoff slowly.

- Undo the self-sealing lock nut of the adjustment screw S on the top side of the valve.

- Use a properly fitting hexagon socket screw key to move the adjust-ment screw in the thread play until no more air escapes.

- Tighten down the lock nut again.

FB - AZ 2 (E)

1.) Description of a lifting drive (AZSTB 0 - III)

Acceleration

The pump motor starts up with the help of a star/delta connection or a soft starting device. During the running up of the soft starting device or the star connection, the oil conveyed by the pump flow almost completely depressurised back into the tank.

The depressurised oil circulation is realised by means of a pre-setting of the start-up valve piston made using the adjustment screw A.

When switching over to the delta connection, the solenoid valves V1 (S1) and V4 (S4) are excited simul-taneously and, as a result, the start-up piston closes slowly. The closing speed and therefore the accelera-tion of the elevator can be changed by replacing the nozzle D1. Ideally, the elevator system should be adjusted so that, with cold oil and empty elevator cage, it starts to drive away approx. 0.5 seconds follo-wing the excitation of the solenoid valves.

For the version with direct switching-on of the motor (valve designation 3MR), solenoid valve V1 (S1) is missing. Here the valve V4 (S4) is excited simultaneously with the pump motor. The acceleration is then carried out as described above.

Nominal speed

Following the acceleration phase, the start-up valve piston has closed completely and the elevator drives at full speed.

The high lifting speed is solely dependent on the motor-pump combination.

Deceleration

At the deceleration point before the selected storey, the solenoid valve V4 (S4) is de-energised and the deceleration phase is initiated.

The control oil, which previously closed the start-up valve piston, flows via the adjustable throttle D7 back into the tank. The start-up valve piston opens damped and lets a specific quantity of the oil con-veyed by the pump flow back gradually into the tank. Due to the decreasing oil flow, the non-return valve closes until a needle operated by this non-return valve allows control oil to flow to the start-up valve piston again so that this piston cannot open any further. A residual quantity of working oil flows to the cylinder which then moves at creep lifting speed. This speed can be adjusted at the screw SH. In this phase, the quantity regulator ensures almost load-independent and temperature-independent dece-leration.

Stopping

After reaching the storey, the pump motor and the solenoid valve V1 (S1) are switched off immediately or the solenoid valve is de-energised already approx. 2 cm before the stopping location and the pump motor remains switched on via time relay for approx. 1 second which results in a softer stopping opera-tion (soft stop) using the nozzle D6.

When the storey has been reached, the pump motor is switched off, the non-return valve closes comple-tely and the oil column settles down on it.

(31)

2.) Description of a lowering drive (AZSTB 0 - III)

Acceleration

The solenoid valves V2 (S2) and V3 (S3) are excited simultaneously so that the working oil is then con-veyed back via the lowering valve stop piston via the adjustable throttle D3 into the tank.

The lowering valve piston including the lowering valve stop piston opens as a result and the working oil underneath the lifting piston also flows back to the tank and the elevator accelerates up to full speed.

Nominal speed

When the lowering valve pistons have opened all the way to the stop of the adjustment screw HS, the full lowering speed is reached.

The adjustment screw HS is used to limit the maximum lowering speed.

In this phase, the control slide gate installed upon customer request ensures equivalent lowering speed at various temperatures and pressures.

Deceleration

At the deceleration point before the stopping location, the solenoid valve V3 (S3) is de-energised and the deceleration phase is initiated.

Control oil then flows via the adjustable throttle D4 back to the lowering valve which closes damped up to an adjustable residual cross-section. This residual cross-section determines the magnitude of the pre-cision lowering speed and is adjusted at the spindle FS.

Stopping

After reaching the storey, the solenoid valve V2 (S2) is immediately de-energised or is switched already approx. 2 cm before the stopping location so that the elevator drives softly into the storey with the help of the nozzle 5 (soft stop).

3.) Function of the mounted valves

Safety valves

When the pressure in the control block exceeds the pre-set value, the safety valve opens so that the con-trol oil can flow back from the start-up valve piston into the tank. Accordingly, the start-up piston can then open and the oil conveyed by the pump can flow back to the tank.

Emergency discharge

In order to able to lower the elevator in case of malfunctions, manual operation of the solenoid valve V2 (S2) is possible.

Piston lowering prevention (KAV)

The piston lowering prevention device is used for 1:2 systems and is pre-set to a value of approx. 5 bar ex factory.

This means that the control oil flows through the piston lowering prevention device during each regular lowering drive. If the elevator cage is held in position for maintenance purposes and the pressure drops below the pre-set 5 bar, the piston lowering prevention device will prevent unintentional lowering of the piston and slack cable creation by shutting off the control oil in front of the solenoid valve.

2.) Adjustments in lifting drive

a.) D1 acceleration

Permanently adjusted ex factory, can only be changed by replacing the nozzle. The

fol-lowing applies:

larger nozzle = greater acceleration

smaller nozzle = less acceleration

b.)A start-up lifting adjustment

Spindle A influences the period of time between giving the command and starting up.

With an empty elevator cage and cold oil, the spindle must be adjusted so that the

ele-vator starts up after approx. 0.5 seconds following excitation of the solenoids S4 and

S1. The following applies:

Turn inward = short time

Turn outward = longer time

This spindle must never be screwed in too far so that the elevator starts up abruptly

fol-lowing excitation of the solenoids.

c.)SH creep lifting speed

This screw is used to adjust the driving speed into the stopping location and therefore

also the stopping jolt. The following applies:

Turn inward = lower creep lifting speed

Turn outward = higher creep lifting speed

d.) D7 deceleration upward

The deceleration of the nominal speed to creep lifting speed can be changed using the screw D7 on the solenoid valve S4. The following applies:

Turning inward results in soft transition, longer deceleration distance Turning outward results in abrupt transition, shorter deceleration distance e.) D6 soft stop

Only operative with pump run-on, after the solenoid S1 is de-energised in the stopping location. Per-manently adjusted ex factory, can only be changed by replacing the nozzle. The following applies:

Turn outward = higher main lowering speed Turn inward = lower main lowering speed b.) FS precision lowering speed

The screw FS is used to adjust the precision lowering speed. The following applies:

Turn outward = higher precision lowering speed Turn inward = lower precision lowering speed c.) D3 acceleration downward

The throttle screw D3 on the solenoid valve S2 is used to adjust the acceleration from 0 to the nominal speed downward. The following applies:

Turn inward = softer start-up

Turn outward = more abrupt start-up d.) D4 deceleration downward

The throttle screw D4 on the solenoid valve S3 is used to adjust the deceleration from nominal speed to precision lowering speed. The following applies:

Turn inward = softer transition, longer deceleration distance

Turn outward = more abrupt transition, shorter deceleration distance e.) D5 soft stop

Permanently adjusted ex factory, can only be changed by replacing the nozzle. The following applies:

Smaller nozzle = softer stop Larger nozzle = more abrupt stop

(35)

4.) Adjusting the pressure limitation switch

4.1) Version in accordance with TRA

4.2) Version in accordance with EN 81-2

a.) Normal operation

During normal operation, the green LED chain indicates the current valve pressure and, by means of a blinking LED, the switching point with an accuracy of 10 bar in each instance. The yellow LED indicates the switching state, as a break or make contact according to use.

b.) Programming

To adjust the switching point, press down the pushbutton SET S ENTER for approx. 5 seconds until is indicated in a resolution of 1 bar. As soon as the indication is running, the value can also be chan-ged using the inching mode. The illuminated LED then indicates the scale value and the blinking LED 1/10 of the scale value. Example 57 bar:

The changed value is stored by pressing the key SET R ENTER S. The new value becomes effective and the device jumps back to normal operation..

The return switching point is automatically set 1 bar lower and therefore does not need to be pro-grammed. The new setting is locked by pressing both pushbuttons simultaneously for approx. 10 seconds. Following the locking operation, the display goes out for a short time.

The pressure switch is an overload safety device. It is operated by the pressure from the cylinder. The adjusted pressure must be higher than the static pressure at full load but lower than the adjusted pressure at the pressure limitation valve. The following adjustment applies

The adjustment functions as follows:

Turn inward = increase shutoff pressure Turn outward = decrease shutoff pressure

The pressure limitation switch is pre-set by the factory.

For explanation of the electric connections, refer to catalogue sheet

Operator panel of the electronic pressure switch:

- -pushbuttons for adjustment -LED chain for pressure indication -LED yellow for indication of the switching state

This pre-set pressure switch detects whether an overload of 10% of the nominal load, but at least 75 kg, in accordance with EN 81-2 has been achieved and reports this via a switching signal. A driving-away of the elevator cage in case of overload is to be prevented and therefore the use of a device in the safety circuit is not possible. For explanations of the technical data and the con-nections, refer to catalogue sheet.

5.)Testing the piston lowering prevention device (KAV)

The piston lowering prevention device ensures unintentional lowering of the piston rod in

case of jamming of the elevator cage or in case of activation of the catching device

(sole-noid valve V2 (S2) electrically or manually during operation) and checks the control

block minimum pressure at which the lowering valve is closed whenever this value is

exceeded.

The piston lowering prevention device is generally adjusted to a fixed setting of 3 bar; an

alteration of the response pressure is not possible

Procedure: - Drive elevator cage approx. 2 m upward.

- Support elevator cage or put into catching device. - Undo the piston rod from the elevator cage.

- Press emergency discharge button - piston rod must not descend alone.

6.) Adjustment of the bypass valve

The bypass valve is installed between the valve block or manual pump and the

con-nection flange. It is used test the pipe rupture valve during a TÜV (German technical

control board) inspection. To operate the bypass valve, the test wheel must rotated

counterclockwise. If the pipe rupture valve does not respond, an increase in the flow

rate is required. The adjustment is made as follows

- Undo the lock nuts.

- Unscrew the throttle screw 1-2 revolutions. - Test setting.

- Screw in throttle screw and lock in place

7.) Adjustment of the manual pumps

The manual pump is installed for hydraulic systems with a catching device and suspension 1:2. For the valve blocks AZSTB / AZRV 1 and AZSTB / AZRV 2, the manual pump of the type HP 25 is used. It is flange-mounted between the ball valve and valve block.

The pump can be installed in two different positions. The manual pump can be rotated by 180 degrees in each instance by undoing the 4 flange screws.

For the valve block AZSTB 0 and III, the manual pump of the type 22 is used. It is permanently installed on the cover.

The manual pump is generally used for lifting out of the catching device.

To protect the hydraulic system, the manual pump is equipped with a pressure limitation valve. For the adju-stment of the pressure limitation valve, the following applies

:

adjustment = P stat. max x 2,3 Adjustment:

Undo lock nut. Use the adjustment screw to set the calculated pressure. Clockwise rotation will increase the pressure, and counterclockwise rotation will decrease the pressure, which is indicated on the pressure gauge.

The items used are included on the sheet Assembly Instructions Con-trol Block and the adjustment instructions used on the sheet Adjust-ment Instructions Control Block.

1.) Possible malfunctions in lifting drive

Internal leakage so that the elevator picks up again frequently Elimination of malfunction:

a) Check whether the sealing washer (Item 25) of the lowering valve piston has been damaged by dirt par-ticles. If there are any pressure marks, the sealing washer must be replaced.

b) Check whether the precision lowering valve V2 (S2) is leaky. The best way is by replacing the valve or by checking it with the solenoid valve test board.

c) Check whether the seal of the lowering valve piston (Item 8) or the lowering valve stop piston is dama-ged. If this is the case, the entire piston must be replaced.

d) In case of damage, replace the sealing ring of the non-return valve piston. When being put into service, the elevator has no creep lifting drive.

Elimination of malfunction:

a) Check whether the solenoid valves V1 (S1) and V4 (S4) have been correctly connected. During the entire lifting drive, V1 (S1) must be energised and V4 (S4) de-energised at the start of deceleration. b) Throttle D7 is screwed in too far. Unscrew throttle approx. 1/8 revolution.

Following a longer period at standstill with cold oil, the elevator no longer has creep lifting capacity. (machine room is not heated)

a) Unscrew throttle D7 approx. 1/8 revolution and move the curves for switching off the solenoid valve V4 (S4) in order to extend the creep travel distance.

Elevator does not engage in lifting drive; no pressure is built up. Elimination of malfunction:

a) Clean filter of solenoid valves V1 (S1) and V4 (S4). b) Solenoid valves V1 (S1) and V4 (S4) may be defective. c) Clean nozzle D1 underneath valve V1 (S1).

d) Setscrew A has been unscrewed too far. e) Safety valve tappet (Item 17) is jammed. When under load, the elevator stops in lifting drive Elimination of malfunction:

a) Check maximum pressure; setting may be too low.

b) For the block type AZSTB IA 4MR, the solenoid valves may have been incorrectly connected or the valve V1 (S1) may be defective.

c) Creep lifting speed is set too low, the elevator stops before reaching the stopping location or does not pick up again.

2.) Possible malfunctions in lowering drive

Elevator does not go into lowering drive and also cannot be lowered using the emergency discharge valve V2 (S2).

Elimination of malfunction: a) Open throttle D3 slightly.

When being put into service, the elevator has no creep lowering drive. Elimination of malfunction:

a) Check whether the solenoid valves V1 (S1) and V3 (S3) have been correctly connected. During the entire lowering drive, V2 (S2) must be energised. V3 (S3) is de-energised at the start of precision lowering speed.

b) Unscrew throttle D4 approx. 1/8 revolution.

Following a longer period at standstill with cold oil, the elevator no longer has precision lowering speed. The oil is much colder than during the last operation or the machine room is not heated and therefore exposed to extreme temperature variations.

a) Unscrew throttle D4 approx. 1/8 revolution and move the curves for switching off the solenoid valve V3 (S3) in order to extend the switching-off distance.

SH - AZ 2 (E) 07.11.00

SH - AZ 2 (E)

1.) Purpose

These safety instructions serve the purpose of preventing risks for persons working on ALGI elevator valves as well as maintaining the reliability of these systems

2.) General safety instructions

- Tasks on hydraulic systems should only be carried out by trained expert personnel. - As a general rule, only the tool specifically suitable for each task should be used.

- During the execution of maintenance and repair tasks, the elevator system must be protected from being used.

- Due to the pressure load on the components, only original spare parts are allowed to be used.

3.)

Safety instructions for the ALGI elevator control block and control valve programme

- Prior to performing any tasks, the elevator must be protected from being used.

- For all tasks during which parts are unscrewed, the system must be switched off at the main switch, the ball-type shutoff valve closed and the pressure discharged at the emergency discharge valve.

- For all tasks, the assembly instructions specifically prepared for this product must be taken into account.

- Safety devices such as the emergency discharge valve and evacuating unit must not be blocked or the corresponding information signs be dirty or removed.

- The adjustment of the safety valve is accepted in the course of the TÜV inspection and is not allowed to be adjusted higher than the value indicated on the nameplate later on.

- The same applies to the adjustment of the pressure limitation switch and the safety valve on the manual pump.

- With respect to sealing elements, only original ALGI spare parts should be used in order to guarantee dimensional accuracy and therefore perfect function of the seals.

- Prior to opening the ball-type shutoff valve, all fastening screws must be re-tightened.

- Following the assembly tasks, the ball-type shutoff valve must only be opened slowly in order to pre-vent pressure peaks.

(41)

1.) Purpose

The maintenance of the elevator control blocks and their mounted valves serves the purpose of keeping the elevator system in a perfect and safe state of operation at all times

2.) Measures

- Cleaning: The valve must be cleaned externally of dust and dirt so that even smaller leaks

can be detected. The applies especially to the connecting points with the mounted valves, ball-type shutoff valve and hydraulic line.

The use of aggressive cleaning agents must be renounced in order to exclude any form of damage to the seals. Loose parts on the hydraulic unit cover must be removed

- Inspection: Verification of the valve for external leaks, damage or deformations. Self-sealing nuts on adjustment spindles must be re-tightened as required or defective sealing elements renewed with original spare parts. Damaged parts (setscrews, lock nuts, etc.) must be renewed. During the trial drives, attention must be paid to untypical noise development. Verification of the valve for internal leaks by closing the ball valve and checking the pressure gauge. If an extreme drop in pressure is detected, the internal seals must be renewed by referring to the assembly instructions - Trail operation: During the trial operation, the systems must be protected from being used. The

driving characteristics of the elevator cage must be checked as well as the achie-vement of high speeds in both directions and the corresponding functions of the mounted valves.
