1. Basic instructions

1.1 Designation

Designation of the manufacturer:

See page 1 of this Operating Manual

Device serial number

See the rating plate on the unit: it will

show the complete ratings and the electri-

cal specifications.

1.2 Purpose for which this system was designed

This Operating Manual contains the information required for operation of the products de-

scribed here, for the purpose for which they have been designed. This Operating Manual

is intended to be used only by technically qualified staff.

“Technically qualified staff” in the sense of this manual is defined as those persons who –

as a result of their training; their experience; the instructions which they have received; as

well as their knowledge of the relevant standards, regulations, accident-prevention regu-

lations, and conditions under which this system will be used in the company –have been

authorized by the person responsible for the safety of the company facilities to carry out

the activities and actions required for operation of the equipment described below, and

who can recognize and prevent any possible dangers arising from such operation (this

definition of technically qualified staff has been provided in IEC 364).

The User must by all means observe the requirements and limit values, as well as all

safety instructions, given in this Operating Manual. Any use of this device not in conformity

with these stipulations shall be considered tobe in violation of the use for which this system

was intended. If this device must be operated under special conditions, or with special

modes of operation, then this will be authorized only after consultation with the manufac-

turer, and after obtaining his prior and express approval.

This Automatic Vicat Needle Apparatus is intended only for determining the setting time

for cement. The beginning and the end of the setting process is determined by the pene-

tration behaviour of a steel needle into a cement paste sample, under certain specified

conditions.

IMPORTANT

NOTE:

The instructions given in this Operating Manual are valid only under

conditions in which the device is correctly used. In order to properly

perform the test, the User must observe the specific standards that ap-

ply to the test.

1.3 Conditions under which this system may NOT be used

This system has been designed and built in accordance with the latest state of the engi-

neering art, and with recognized engineering rules and regulations. However, danger can

arise to the health and safety of the User, and of third parties, and damage can result to

the components of the system, or to other objects of value in the vicinity. For these rea-

sons, the User must observe the following instructions:

Do not take the device apart, and do not try to repair or to modify it.

Operate the device only in the range of voltage supply as given in this Operating Manual.

Do not operate the device in places that are subject to the following conditions:

Formation of ice, Heat radiation, Formation of condensate, Dust, Corrosive gases, Vibra-

tions, Severe impacts, Do not operate the device in places with great relative humidity and

temperature fluctuations.

Caution

The mixing of cement with water causes the release of alkaline sub-

stances. In working with concrete, it is essential to take all necessary

precautions to prevent dry cement from entering the eyes, mouth, or

nose. Use protective clothing to prevent skin contact with wet cement

or concrete. If cement or concrete enters the eyes, immediately and

carefully wash out the eyes with clean water. Seek medicalhelp without

delay. If moist concrete comes into contact with the skin, wash it off

immediately.

Caution

Be sure to take all normal and logical precautionary measures to en-

sure that the equipment is not subject to impact, and that it is not dam-

aged in any other way.

We recommend that the Automatic Vicat Needle Apparatus be placed on a work

desk, so that the drum with the plot of measuring results is located at a conven-

ient level for the operating personnel.

The main working position for the operating personnel is in front of the device.

1.7 Electrical connections

Danger

In accordance with the pertinent standards, the yellow-green connec-

tion terminal must be connected to the earthing system before addi-

tional electrical connections are made.

Before making the electrical connections. Also check the machine rat-

ing plate to make sure that the ratings of the building power supply

conform to the requirements of the product for voltage, wattage, am-

perage, and frequency.

The technical characteristics of this safety device must also satisfy the

standards that apply in the country in which the machine is installed.

Caution

The manufacturer of this product cannot be held liable for any damages

that result because the information here is not observed.

Actual voltage: 10% of the rated voltage

Frequency: 50 Hertz 1% of the rated frequency, continually; 2% of the rated fre-

quency, on a short-term basis

The manufacturer shall not be liable for damages to persons or property that arise be-

cause the above instructions have not been observed.

We recommend the use of a residual-current-operated circuit-breaker (RCCB) with

30-mA rated residual-current trip.

2. Characteristics of the equipment

The noise levels given here do not necessarily represent safe levels for persons operating

the equipment. The safety and suitability of the noise levels for operating personnel are

influenced by other factors such as the following: length of time that personnel are ex-

posed to the noise, the surrounding environment, other equipment installed in the vicinity,

etc.

Official data on noise-exposure levels are necessary to evaluate the damage that person-

nel can suffer from being subjected to the noise from this equipment.

Sound pressure level equivalent “A” at the workplace:

23 dB(A)

Standards applying to the above data:

EN ISO 3746

This system belongs to those items of equipment whose acoustic emission in general does

not reach a rating level of 90 db(A) (in accordance with DIN 45 635).

The noise emitted by the system will depend on various factors: e.g., the specific product,

the place of installation, and the like. For this reason, it is not possible to indicate a gener-

ally valid sound pressure level for this system.

3. Operating the Vicat needle apparatus

3.1 Putting the machine into operation

Attention

For reasons of safety, the drop rod must be removed from the machine

before it is transported. Before placing the Vicat needle apparatus into

operation, take the drop rod and insert it into the machine at its proper

place.

The recording stylus for plotting the Vicat results is delivered with a ballpoint-pen refill or

with a propelling-pencil (mechanical-pencil) lead. After you insert the drop rod, you must

use the knurled nut to set the exact distance between the point of the recording stylus and

the recording drum.

Insert the needle into the drop rod as far as it will go. Then lightly

tighten the headless grub screw with the supplied no. 2 Allen

wrench.

The next step is to wrap the recording paper around the recording drum. Use the paper-

holding springs to hold the paper in place, and shove the paper up to the edge. The lowest

paper-holding spring should be set so as to be positioned just over the edge.

Carefully insert the drop rod, from the top, all the way into the cover of the system housing

lid, until it will go no farther. Push the recording stylus (ballpen refill or pencil lead) back so

that it moves past the retaining spring of the recording drum with the paper.

Switch on the system by using the switch on the rear side.

The system will now perform a self-test. If the system successfully passes the self-test, it

will signal that it is ready for operation by showing the green signal lamp.
