safe and appropriate installation and commissioning of the

Velocity-Time-Meter, VTM. It also contains information about

service and maintenance, and how to remedy simple malfunctions

yourself.

O Read this instruction manual carefully, especially chapter 3

“For your safety”, before you start working with the VTM.

1.1 Abbreviations

2 Applications

VTM is used to measure time and velocity for pneumatic

components.

Abbreviation Meaning

VTM Velocity-Time-Meter

For your safety

30 AVENTICS | VTM | R402002668-BDL-001-AC

3 For your safety

The VTM has been manufactured in accordance with current

engineering standards and safety regulations. Even so, there is a

risk of injury or damage if the following general safety instructions

and the specific warnings given in this instruction manual are not

observed.

O Read these instructions completely before working with the

VTM.

O Keep these instructions in a location where they are accessible

to all users at all times.

O Always include the operating instructions when you pass the

VTM on to third parties.

3.1 Intended use

O The VTM may only be used within the limits listed in the

technical data.

O The VTM is primarily intended to be used in industrial

applications.

Intended use includes having read and understood these

instructions, especially the chapter “For your safety”.

3.2 Improper use

It is considered improper use when the VTM

W is used for any application not stated in these instructions, or

W is used under operating conditions that deviate from those

described in these instructions.

For your safety

AVENTICS | VTM | R402002668-BDL-001-AC 31

English

3.3 Personnel qualifications

Installation, connection and commissioning require fundamental

knowledge of electronics and pneumatics, as well as knowledge of

the applicable technical terminology. For this reason, the device

may only be installed, connected and commissioned by a specialist

in electronics and pneumatics or by a person under the control and

supervision of such a specialist.

Qualified personnel are those who can recognize possible hazards

and institute the appropriate safety measures due to their

professional training, knowledge, and experience, as well as their

understanding of the relevant conditions pertaining to the work to

be done. Qualified personnel must observe the rules relevant to

the subject area.

3.4 Safety instructions

In this document, there are safety instructions before the steps

whenever there is a danger of personal injury or damage to the

equipment. The measures described to avoid these hazards must

be followed.

Safety instructions are set out as follows:

W Safety sign: draws attention to the risk

W Signal word: identifies the degree of hazard

W Type of risk: identifies the type or source of the hazard

W Consequences: describes what occurs when the safety

instructions are not complied with

W Precautions: states how the hazard can be avoided

SIGNAL WORD

Type of risk

Consequences

O Precautions

For your safety

32 AVENTICS | VTM | R402002668-BDL-001-AC

The signal words have the following meaning:

3.5 Observe the following for the VTM

In pneumatic systems, good design aims to minimise the risk of

failure or injury in the event of malfunctions.

Particular attention must be paid to the following:

W Collisions between moving parts must not be possible.

W Unexpected and unwanted cylinder movements must not be

possible to occur.

W Vented strokes must not be possible (ie a cylinder movement

when the opposite chamber is not pressurised).

General information W Observe the local regulations to protect the environment in the

country of use and to avoid workplace accidents.

W The VTM must never be altered or modified from its original

configuration.

W The VTM may only be used within the power ranges stated in

the technical description. See the product catalogue.

Table 1: Hazard classes according to ANSI Z535.6–2006

Safety sign, signal word Meaning

WARNING

Indicates a potentially hazardous situation which, if not avoided, could

result in death or serious injury.

NOTICE

If this information is disregarded, the operating procedure may be

impaired

WARNING

Damage may occur when built-in protection is bypassed

When you tamper with sensors or control signals to valves you bypass any built-in

protection. This increases the risk of injury to personnel and damage to equipment.

O Vented strokes are especially serious. Here there is a risk of extremely high speeds,

which may lead to failures in which the load comes loose and goes outside the normal

area of action.

For your safety

AVENTICS | VTM | R402002668-BDL-001-AC 33

English

On installation W Position cables where people cannot trip over them.

Maintenance W Never use solvents or strong detergents. Never hose down the

VTM with water. Clean the VTM only with a cloth slightly

moistened with water or a mild detergent.

Waste disposal W Dispose of the device in accordance with local regulations.

7.1 Commissioning

Note: The cylinder may only be commissioned by a specialist in

pneumatics or by a person under the control and supervision

of such a specialist (see “Personnel qualifications”, page 31).

7.2 Velocity measurement

Note: The meter can only measure the velocity of cylinders that

have a magnet.

Fig. 4: Meter with velocity probe connected

1. Plug the connector of the probe (1) into the meter.

2. Switch on the instrument by pressing “On”.

3. The word “Velocity” appears on the display. If not, press the

function button repeatedly until it does.

4. Press “Enter” to choose velocity measurement.

5. Position the probe at least one metre from powerful magnets

or wires carrying a high current, and calibrate it by pressing

“Cal”.

6. The meter is now ready to be used for velocity measurement.

Fig. 5: The velocity probe applied to a cylinder

7. Position the locating edge (1) of the probe in the sensor slot of

the cylinder. Apply the probe to the point on the stroke of the

cylinder where you want to know the velocity of the cylinder.

You can use the strap to fix the probe in place.

8. The arrow on the probe must be pointing in the direction of

motion of the cylinder (2).

9. Press “Enter” to set the instrument to standby for

measurement.

10. When the sensors have registered the passing of the piston, the

velocity appears on the display.

11. To repeat the velocity measurement, press “Enter” to set the

instrument to standby for measurement.

Explanation The position of the sensors in the probe is indicated by two marks

in the form of dots. VTM measures the time taken by the piston to

travel between the two dots and calculates the average velocity.

Usually it is the peak velocity of the cylinder before the piston

reaches the damping position that is measured.

Limitations The meter is limited to velocities up to 9.99 m/s. If you measure the

velocity in the wrong direction, “Error” appears on the display.

8. Press “Enter” again to start measurement.

9. To repeat the time measurement, press “Enter” to set the

instrument to standby for measurement.

Explanation With a falling flank, triggering takes place when the voltage goes

from high to low. With a rising flank, triggering takes place when

the voltage goes from low to high.

In the example above, initially the right-hand sensor is low and the

left-hand sensor is high. The meter waits for the cylinder to begin

its plus motion so that the left-hand sensors goes low and timing

can start. At the end of the stroke, the right-hand sensor goes high,

measurement ends and the time difference between the two

flanks is displayed.

Limitations The longest possible measuring time is 60 seconds.
