1 Safety advice

1.1 Safety instructions and warnings for user

This manual contains all information required for the correct operation of the Roland equipment.

It has been written for technically qualified personnel.

Unauthorized tampering with the unit, especially ignoring the warnings in this manual can cause

malfunction and damage to the unit. Only authorized personnel should be allowed to make

changes to the unit and perform cable connections especially the power supply.

Should it be necessary, e.g. in case of service or repair, to make measurements within the unit,

then all customary accidents prevention procedures should be observed. Only professional

electrical tools should be used.

Note The factory pre-settings – especially the upper / lower limit values – have

been chosen such that an optimal machine protection is ensured.

Diverging settings can impair the machine protection.

1.3 Intended use

Flexible Manufacturing Systems in the sheet processing industry require reliable Double Sheet

Control systems in order to protect presses and other sheet processing machines against damage

caused by feeding multiple sheets.

The Double Sheet Detector R1000 L20 was specifically developed for this technical environment.

The reliable function of the Double Sheet Detector depends therefore most importantly on the

selection of the correct sensors and the mounting of the sensors.

1.4 General hints for process reliability

The process security of the system is influenced by the following factors:

• Stability of the measuring values

• Setting of under-gauge threshold and over-gauge threshold

• Evaluation of the status signals

Stable measuring conditions will result in stable measuring results. Varying measuring results are

undesirable, because in such cases the user is inclined to decrease the under-gauge threshold

LOW and to increase the over-gauge threshold UP. On doing so, the user puts up with the

drastically increasing risk of not detecting a double sheet.

The following external factors decisively influence the stability of measuring results and need to be

considered for operation of a double sheet detector:

• Optical characteristics of the material

• Tolerance in material thickness

• Contamination of the material

• Geometric conditions at the place of measurement (Stability of the sensor gaps)

• Contamination of the sensors (dirt, oil …)

From this some simple rules can be derived, which enable a high process security when abided by:

• Every different sheet (Thickness, material and contour) is measured with separate

measuring program.

• Adjust the switching thresholds as tight as possible!

• Keep the sensor gap constant!

• Make use of the air connection to keep the sensors clean!

Furthermore it is necessary that the machine control:

• checks all status signals of the L20,

• checks the 0-sheet signal.

While measuring, only the 1-sheet signal may occur. If 0-sheet or 2-sheet occurs, the measured

sheet may not be transported on. In such cases, the sheet will usually be removed.

• The machine controls needs to evaluate all status signals !

Checking-up through the 0-sheet signal is to assure that a sheet really is between the sensors

during measuring. If 0-sheet occurs while measuring, the measurement is not correct. For example,

a defective sensor holder might change the sensor gap. Monitoring the sheet thickness would then

only be seemingly performed.

In case of double sheet severe consequences could then result.
