1 Product description

1.1 Intended use

The structural component SM01-001 may be used exclusively as an electrical fail-safe circuit in all control

systems for lifts in line with

EN 81, Part 1 and Part 2, clause 14.1.2.3

TRA 264.2

95/16/EU directive, article 1, para. 1 and article 8, para. 1.

The structural component SM01-001 is fitted with four safety relays and associated connection terminals.

The component is housed in an open casing which is designed to be secured on mounting rails.

1.3 Functional description

When both the landing door and the door of the lift car are open, the approach and positioning of the lift

must be monitored by two independent contact elements.

Within the SM01-001 safety circuit module itself, the two independent zone switches S71 and S72 are

monitored by means of relays K71, K72 and K73 to ensure that they are operating perfectly. The correct

output of these relays is controlled by the monitoring circuit that exists between terminal 7 and terminal 12

of the SM01-001 safety circuit module. In the case of non-equivalence operation of relays K71 and K72,

the flow of current to terminal 12 will be interrupted in accordance with EN 81, Part 1 and Part 2, no.

14.1.2.3.2 (the "Status" LED will go out) and any attempt to re-start the lift will be prevented by the

sequential circuit.

The bypass feeder (terminal 1 and 2) is only closed as the lift approaches and is being positioned in the

zonal area.

When both the doors are open, the contact pieces of the safety circuit module work directly on the lock

gate. If the lift approaches and is being positioned within the zonal area, the lift will be shut down

immediately in the event of an interruption of this sort.

An electronic display circuit showing "LED Bündig / Level" which is fitted on the component will indicate

whether the lift car is level when zone switch S72 is actuated.

IMPORTANT!

The procedure to be used to carry out a performance test can be found in the section on „Commissioning“.

2 General safety instructions

2.1 The need for care on the part of the operator / demands made of the op.personnel

The operator must

make the operating instructions available to all personnel and ensure that all personnel have read and

understood them,

ensure that the structural component is used for the application intended,

ensure that only a sufficiently qualified person carries out operation and maintenance tasks.

2.2 Clarification of the safety symbols used

DANGER!

indicates a real threat of danger to life and limb.

WARNING!

indicates a potentially dangerous situation. Should the instruction be ignored, either serious

injury or death may occur. This instruction is also used to warn of any possible dangers

posed to the machine itself, to materials used or to the environment.

NOTE!

identifies information which will help towards a better understanding of the procedures

involved.

2.3 Fundamental safety measures

Operation when the current is live represents a real DANGER to life and limb.

Disconnect the power supply before carrying out maintenance and repair work (mains switch,

fuse).

Never remove safety devices or effectively put them out of action by making adjustments to

them.

Observe the regulations given in the DIN VDE 0100 and VBG 4 standards.

3 Transport / assembly

Ensure that the limit values shown below are not exceeded:

Ambient temperature Shock resistance Vibrostability

0 ... + 65 °C 15 g at 11 ms 10 g at 2 Hz

Use in those lift control systems as laid down in section 1.1 is only permitted provided the structural

component is completely protected against the penetration of water, conductive dust particles and dew.

The component must therefore be housed in a casing or box with a system of protection of at least IP 33.

4 Commissioning

4.1 Connecting up to the power supply


Carry out the following on the system before commissioning:

1. Isolate the system

2. Prevent against restoration of power

3. Verify the safe isolation from the power supply

4. Earth and short-circuit

5. Mask or safeguard any adjacent parts which may be live

Now connect up the structural component according to the details given in the circuit diagrams:

WARNING!

Do not connect the negative pole of the emergency power source to the PE connection or to

the 0V connection of the 24VDC supply voltage. By avoiding this you will prevent a feedback

of energy from the emergency power source entering the 24VDC supply voltage.

NOTE!

Observe the information given in the magnetic switch diagram included in the wiring

documents.

Check the following before running for the first time:

that all clamping joints are correctly connected and tight

operation of the component in line with the details given in the section on „Performance test“.

4.2 Performance test

Precondition: Switches S71 and S72 are installed in line with the details given in the magnetic switch

diagram and the switching contact is closed, i.e. the lift car is positioned within the

zonal area.

Procedure:

1. When starting the lift car, keep switch S71 closed. To do this, place a wire jumper from terminal

6 to terminal 3 of the safety circuit module.

2. Now call the lift to any level.

As the lift approaches the level in question, the lift door and locking device switch will no

longer be bypassed. The "Status" LED will no longer be lit and any further movement of

the lift will be blocked.

NOTE!

Should you be operating a lift with a hydraulic drive and should you have requested the lift to

descend, any fault in the SM01-001 safety circuit module will not immediately block any

further movement of the lift but will in fact first lower the lift as it would do in an emergency.

Only then will any further movement of the lift be blocked while it sits at the lower level.

3. Now remove the wire jumper and switch the control system OFF and ON again. The block will

thus be lifted.

Any further movement of the lift will proceed as normal.

4. Repeat points 1 - 3 for switch S72. Ensure that you have now placed a wire jumper from

terminal 6 to terminal 4 of the safety circuit module.

5 Help in the event of any malfunctions

Only attempt to eliminate a malfunction if you happen to possess the relevant qualification to do so.

Also read the section on "General safety instructions".

5.1 Possible causes of malfunctions and their elimination

NOTE!

Since the introduction of the MPK generation of A series control systems, all faults are now

stored in the MPK event recorder. The way in which you read this recorder and obtain

supplementary information on the entries contained therein is described in the MPK

document entitled „Brief instructions“. The terms „readjustment, readjust, make good“

correspond directly with the term „reset“ used in Part 1 and Part 2 of the EN 81 standard.

Procedure for eliminating the malfunction:

1. Read off the information given in the event recorder.

2. Is the „Status“ LED on the SM01-001 safety module lit up?

NO: see case study 1

YES: see case study 2

Case study 1:

Possible causes of the error messages:

re. The zone switches are defective.

re. The position of the magnets does not

match the position of the switches.

The distance between the magnet

and the switch is too great.

Eliminating the cause of the error:

Check the zone switches

Check the current with the zone

switches closed

(SM01-001: current at terminals 3 & 4

measured downstream of terminal 13

greater than 20 V).

Check the position of the magnets.

Check whether adjacent switches are

affected by the magnets (observe the

instructions given by the magnetic

switch manufacturer).

Check the clearance of the car guide

rails.

6 Maintenance / repairs

WARNING!

Do not remove the protective caps on the relays. Never rework the contact pieces of any of

the relays as you would otherwise ruin the component and put other people’s lives at risk

from potentially fatal power currents.

Return the defective component to the manufacturer. You are dealing with a safety device

which is subject to acceptance procedures and special test conditions.

NOTE!

At each maintenance interval check that the component is functioning correctly (see section

on „Performance test“).

Check the clamping joints on the component at least once a year.

Where necessary clean the component with a dry cloth. Do not use detergents or solvents.

7 Decommissioning


Carry out the following on the system before decommissioning:

1. Isolate the system

2. Prevent against restoration of power

3. Verify the safe isolation from the power supply

4. Earth and short-circuit

5. Mask or safeguard any adjacent parts which may be live

NOTE!

When you come to dispose of the component, please observe the legal requirements for the

disposal of hazardous waste material. Have the component disposed of by a specialist

company or return the component to the manufacturer.
