For the connection to the switching inputs you need:

for use as a time switch or a pulse delay (operation mode 1 or 2):

four push buttons, e.g. item no. 84-5212x, x=1..5 (or circuits to

release a switching pulse);

for use as a random switch (operation mode 3):

four switches, e.g. item no. 84-51510 (or comparable circuits);

for use as a start-brake-stopover switch (operation mode 4):

one switch, e.g. item no. 84-51510 (or a circuit to switch over the

signal);

one reed kontact (e.g. item no. 84-53110) or Hall sensor (e.g. item

no. 84-53210) in combination with a magnet (e.g. item no. 84-

53990)

or a photoelectric barrier or similar for initiating of braking;

one push-button (e.g. item no. 84-5212x, x=1..5) or switch (e.g.

item no. 84-51510) to extend the duration of stay manyually.

2. Safety instructions

Mechanical hazards

Cut wires can have sharp ends and can cause serious injuries. Watch

out for sharp edges when you pick up the PCB.

Visibly damaged parts can cause unpredictable danger. Do not use

damaged parts: recycle and replace them with new ones.

Electrical hazards

Touching powered, live components,

touching conducting components which are live due to malfunction,

short circuits and connecting the circuit to another voltage than

specified,

impermissibly high humidity and condensation build up

can cause serious injury due to electrical shock. Take the following

precautions to prevent this danger:

Page 5

tams elektronik

nglish Multi-Timer

Never perform wiring on a powered module.

Assembling and mounting the kit should only be done in closed,

clean, dry rooms. Beware of humidity.

Only use low power for this module as described in this manual and

only use certified transformers.

Connect transformers and soldering irons only in approved mains

sockets installed by an authorised electrician.

Observe cable diameter requirements.

After condensation build up, allow a minimum of 2 hours for

dispersion.

Use only original spare parts if you have to repair the kit or the

ready-built module.

Fire risk

Touching flammable material with a hot soldering iron can cause fire,

which can result in injury or death through burns or suffocation.

Connect your soldering iron or soldering station only when actually

needed. Always keep the soldering iron away from inflammable

materials. Use a suitable soldering iron stand. Never leave a hot

soldering iron or station unattended.

Thermal danger

A hot soldering iron or liquid solder accidentally touching your skin can

cause skin burns. As a precaution:

use a heat-resistant mat during soldering,

always put the hot soldering iron in the soldering iron stand,

point the soldering iron tip carefully when soldering, and

remove liquid solder with a thick wet rag or wet sponge from the

soldering tip.

angerous environments

A working area that is too small or cramped is unsuitable and can cause

accidents, fires and injury. Prevent this by working in a clean, dry room

with enough freedom of movement.

Other dangers

Children can cause any of the accidents mentioned above because they

are inattentive and not responsible enough. Children under the age of

14 should not be allowed to work with this kit or the ready-built

module.

Caution:

Little children can swallow small components with sharp edges, with

fatal results! Do not allow components to reach small children.

In schools, training centres, clubs and workshops, assembly must be

supervised by qualified personnel.

In industrial institutions, health and safety regulations applying to

electronic work must be adhered to.

3. Safe and correct soldering

Caution:

Incorrect soldering can cause dangers through fires and heat. Avoid

these dangers by reading and following the directions given in the

chapter Safety instructions.

Use a small soldering iron with max. 30 Watt or a regulated

soldering iron.

Only use electronic tin solder with flux.

When soldering electronic circuits never use soldering-water or

soldering grease. They contain acids that can corrode components

and copper tracks.

Insert the component connecting pins of into the PCB´s holes as far

as possible without force. The components should be close to the

PCB´s surface.

Observe correct polarity orientation of the parts before soldering.

Solder quickly: holding the iron on the joints longer than necessary

can destroy components and can damage copper tracks or soldering

eyes.

Apply the soldering tip to the soldering spot in such a way that the

part and the soldering eye are heated at the same time.

Simultaneously add solder (not too much). As soon as the solder

becomes liquid take it away. Hold the soldering tip at the spot for a

few seconds so that the solder flows into the joint, then remove the

soldering iron.

Do not move the component for about 5 seconds after soldering.

To make a good soldering joint you must use a clean and unoxidised

soldering tip. Clean the soldering tip with a damp piece of cloth, a

damp sponge or a piece of silicon cloth.

Cut the wires after soldering directly above the soldering joint with a

side cutter.

After placing the parts, please double check for correct polarity.

Check the PCB tracks for solder bridges and short circuits created by

accident. This would cause faulty operation or, in the worst case,

damage. You can remove excess solder by putting a clean soldering

tip on the spot. The solder will become liquid again and flow from

the soldering spot to the soldering tip.

4. Operation overview

Four outputs

The Multi-Timer has 4 outputs to control downstream circuits. In order

to release the switching operations, the contacts of the 4 related

switching inputs have to be closed. The switching duration can be set

via trim-pots individually for the different switching operations.

Four modes of operation

When used in analogue or digital layouts:

1. time switch

2. pulse delay

3. random switch

When used in analogue layouts:

4. start-brake-stopover switch

Setting the mode of operation

The mode of operation has to be set by means of jumpers. The

operation modes 1 and 2 are set to the 4 outputs of the Multi-Timer

individually. Thus using one Multi-Timer as a combined time switch and

pulse delay is possible. When using one Multi-Timer as a ramdom

switch or a start-brake-stopover switch, the setting is effective for the

whole module.

Operating principle "switch"

The Multi-Timer works like a switch and does not provide current for

the operation of downstream circuits at it´s outputs. Therefore the

downstream circuits have to be provided externally with current. It is

possible to use d.c. as well as a.c. voltage for the power supply.
