1.3.2 Factory settings

All valves are factory−set to the values for the particular installation and then tested.

S Pressure−relief valve set to the maximum working pressure

S Bypass pressure as per the calculated minimum static pressure

S Mechanical null point of the feedback sensor

S Emergency−lowering valve set to 5−10% of maximum DOWN speed

1.3.3 Description of function

The lift control valve can be subdivided into 3 main functions.

1. Up section / pressure−relief valve

S Initial position:

UP spool (16) is open in the 0 position; pump flow goes directly to tank

S Up travel / acceleration:

UP spool (16) is progressively closed by the electro−proportional valve (UP solenoid); this results in smooth acceleration of the lift up to maximum speed

S Deceleration:

UP spool (16) is progressively opened by the electro−proportional valve (UP solenoid); this results in smooth deceleration of the lift to standstill

S Overload:

pressure−relief valve (4) and UP spool (16) open when the maximum working pressure set with screw (1) is reached

13/92

C−LRV lift control valve Product description

2. DOWN section / emergency−lowering valve

The down section is constructed in a similar way to the up section. S Initial position:

DOWN spool (14) is closed leak−free in the 0 position

S Down travel / acceleration:

DOWN spool (14) is progressively opened by the electro−proportional valve (DOWN solenoid); this results in smooth acceleration

S Deceleration:

DOWN spool (14) is progressively closed by the electro−proportional valve (DOWN solenoid); this results in smooth deceleration of the lift to standstill

S Power failure / evacuation:

With the electrical emergency−lowering valve (optional), the car can be lowered using DC voltage (⇒ 4.2.4)

S The car can be lowered slowly with the manual emergency−lowering

valve (13)

14/92

C−LRV lift control valve Product description

3. Flow−rate measuring system

S The oil flows through the flow meter (12) in both the up and down

directions

S The baffle−disc is displaced axially as a function of the flow rate

S This axial displacement is converted by a non−contacting feedback

transducer (10) into an electrical DC signal (the feedback signal), which is then sent to the C−DELCON

S The output signal (the feedback) is proportional to the flow rate

S The controller in the C−DELCON works to match the feedback value

to the demand signal

1.4.2 Description of function

S The lift control system sends the command signals to the C−DELCON

via potential−free relay contacts or semiconductors (K1−K4)

S The feedback value is compared with the demand travel curve

throughout the whole travel.

S Deviations from the demand curve are corrected by the UP and

DOWN proportional solenoids

S The closed−loop control ensures that the travel characteristics are

independent of load and temperature

S The inspection speed can be set through contact K5 of the lift control

system (there is no SIU−1 monitoring during inspection speed with K5!)

S Reduced speeds for short travel distances are also possible via

K6−K8

S The C−DELCON enables soft−stopping (gentle halt) with very accu-

rate positioning (±3 mm)

Features

S The travel curve for the up and down directions is set and adjusted

with the Handterminal or a PC

S The demand curve can be set and checked at the C−DELCON while

the lift is at standstill

S Measured values can be checked with the Handterminal

S The C−DELCON card is easy to exchange (1 card for all valves),

which means that rapid fault−fixing is ensured

Important: If the C−DELCON is exchanged, the installation−specific parameters must be replicated in the new card.

1.5.1 Description

The power supply unit is connected directly to the main supply or the control system supply.

The control signals for the C−DELCON are connected to the terminal block (3).

Through the terminals 18–17a (N.O. make contact)

a relay output is provided.

Its function is defined in the C−DELCON by the settings of the "SIU type" and "Relay function" parameters.

Parameter "Relay function"

only SIU

The relay on the power supply unit switches only when there is an SIU fault

The relay on the power supply unit switches with any fault

JP1 selects the relay’s passive state.

1−2 Current flows through the relay in its passive state (no cur-

rent when function is activated)

2−3 No current through the relay in its passive state (current

flows when function is activated)

We recommend that the safety circuit be switched through an auxiliary contactor.

The jumper JP2 connects the Signal GND to Earth potential (default setting).

Important:with Jumper JP2 inserted (Signal GND connected to Earth), then − dependent on the wiring − there is a risk that an earth loop may exist. To prevent earth loops and the associated possible malfunctions, consult the installation circuit drawing.

S The valve test number is stamped on the body (below the manual

emergency−lowering valve) ⇒ 1.2.2.

S The C−DELCON test number is on a label on the connector ⇒ 1.4.

Important: always quote the test number when making enquiries. This makes it easier for the factory to help you!

Important: the test numbers on the C−DELCON and the valve must be the same to avoid the need for resetting.

4.3.2 Checking the minimum static pressure

To check the minimum static pressure (with empty car):

1. Open pressure gauge shut−off valve

2. Read the minimum static pressure on the pressure gauge

3. Compare minimum static pressure on rating plate with actual minimum static system pressure on the pressure gauge

I ⇒ Page 9, Section 1.2.1, Item (4)

4. If the difference is more than 5bar, the maximum pressure setting must be increased by the amount of the difference (⇒ 4.3.4)

I Bypass pressure too high: car travels past landing

I Bypass pressure too low: UP starting jolt

The minimum static pressure shown is correct

Important: if the difference is more than > 10bar, please contact

Customer Services.

4.3.10 Setting the mechanical null point

The null point is factory−set.

With Handterminal, see Page 37, Section 3.3

This can be checked with the Handterminal (or PC). If, on commissioning, the reading is outside the range ±0.05V, then the null point must be reset.

Setting the null point

1. Close the ball valve

2. Connect the Handterminal to the C−DELCON and press key 3 on Handterminal => null point or feedback value will be displayed

3. Using a 3mm Allen key, slacken the adjusting/clamp screw (14) a little

4. Remove Allen key (it has a magnetic influence)

5. Hold the feedback sensor by the plug and move it axially until the feedback reading is less than ±0.05V

6. Tighten adjusting/clamp screw (14)

7. Return to RUN mode by pressing the ↑ and ↓ on the Handterminal simultaneously.

8. Open the ball valve.

The null point is now correctly set

Checking null point after maintenance work

The error memory of the C−DELCON should be checked each time maintenance work is carried out. If there is a warning with regard to nullpoint deviation or, if the actual value for the null point is outside the range ±0.2V, then the null point has to be reset.

4.3.11 Pilot filters

Filter−strainers are positioned upstream of the lowering and lifting valves in accordance with the international standards for lifts. The filters are easily accessible from outside the valve.

Contamination in valve (filter)

This can cause leakage. Never operate the lift without the pilot filter installed.

Carry out regular maintenance as per maintenance plan ⇒ Page 89

Cleaning the pilot filter

1. Switch main switch OFF

2. Close the ball valve

3. Press emergency−lowering lever (vents pressure in the valve)

I the pressure in the valve is vented

Caution

Note the maintenance plan on Page 89

4. Unscrew the filter screw

I with a 22 A/F open−ended spanner

5. Remove filter

6. Clean or exchange the filter

7. Insert the filter

4.3.12 The pipe−rupture valve test

A precondition for testing the pipe−rupture valve is that the lift must be working properly, without any faults.

Uncontrolled descent (free fall)

People may suffer injury and materials may be damaged. Before testing the pipe−rupture valve, make sure that there are no

people or materials in the lift shaft.

Uncontrolled descent (free fall)

Can cause damage to the support frame and car. The elevator car must come to rest within 3 ... 5 metres.

If it does not, immediately switch off the main switch for the lift control system (and repeat the test).

Danger

Attention

Preparing to test the pipe rupture valve

1. Load the car to half of its rated capacity

2. Drive the car to the top floor

Important: do not carry out the test if the car is too close to the lowest floor.

3. Prepare the handterminal or an computer with WinDelta32

300−I−9010212−E−10/08.08

62/92

C−LRV lift control valve Installation and commissioning

Testing the pipe−rupture valve (for C−DELCON software version

2.110 or higher)

1. On the Handterminal, select the Pipe rupture" function in the Information (4) menu under Commands"

I ⇒ Page 76, Section 5.1.4.4

2. Press and hold the + key on the Handterminal; the "DOWN" LED on the C−DELCON will start to flash

3. Send DOWN command

4. Wait until the car is accelerating

5. When the triggering speed is reached, the pipe rupture valve closes and travel stops.

Important: Releasing the + key on the Handterminal stops the travel, and the maximum feedback value is displayed. If the DOWN command is still present on quitting the menu, travel will resume normally.

Important: after the pipe rupture valve has closed, pressure can again build up between the C−LRV and the pipe−rupture valve, causing the pipe−rupture valve to re−open. If the pipe rupture valve is to remain closed for a long period, this pressure must be vented through the manual emergency−lowering valve on the C−LRV. If the hose/pipe is actually burst, the pipe−rupture valve will always remain closed. Very slight leakage through the pipe−rupture valve is permissible.

The pipe−rupture valve has been successfully tested

6. In order that the pipe rupture valve re−opens and the elevator is ready for service: build up pressure using the hand pump or carry out an upwards travel.

The system is once again ready for use

5.2 Calculating the demand values for maximum speed

The demand values are shown on a label on the C−DELCON’s microprocessor

The demand values for the maximum UP and DOWN speeds can be calculated from the following table:

Valve type Flow range, Q

Flow ring Conversion

[l/min.]

C−LRV 175

15–45 46–90

91–250

R45 R90

R250

1V <=> 4.8l/min. 1V <=> 9.7l/min.

1V <=> 29.1l/min.

C−LRV 350 251–500 R500 1V <=> 52.2l/min.

C−LRV 700 400–1000 R1000 1V <=> 112.0l/min.

Calculation example

Flow rate UP (Q) 120l/min. Flow rate DOWN (Q) 150l/min.

Valve selection:

Valve type C−LRV 175 Flow range 91–250l/min. * Flow ring R250 Conversion 1V <=> 29.1l/min. *

Conversion:

Flow rate UP: 120[l/min] / 29.1[l/min] = 4.12V Fast UP

Flow rate DOWN: 150[l/min] / 29.1[l/min] = 5.15V Fast DOWN

→ Settings in the C−DELCON

C−LRV 175 − 120 / 150 − 21 / 45 R 250 − K 251 / 6−80 / 55 bar

* These values are taken from the above table.
