Warnings
The present manual is for device fitters and operators.
We recommend to read this manual carefully before the handling, installation, use, maintenance
and disassembly of the device.
This manual is an integral part of the device and must be kept until the device is decommissioned. It
reflects the technical state of the device at the time of its sale.
The plant builder may include the present manual in the documentation for plant use.
Re S.p.A. reserves the right to update its production and/or manuals without updating products already
sold and previous manuals.
This device is a partly completed machine that complies with directive 2006/42/CE. It is destined for
professional use in industrial settings; it is not able to carry out any process on its own but must be fitted
into a machinery.
It is the machine manufacturer’s responsibility to comply with the laws in force in the country the

We strongly recommend you to use the partly completed machine only for the purpose it has
been designed for.
This device complies with directive EMC 2004/108/CE (D.Lgs. 6/11/2007 n.194).
Handling instructions
When handling take care not to knock the webguide as this may damage it.
Safety notes
The webguide WG251 SKB-B RESMART must be fitted and used by qualified
technical personnel, in compliance with the safety norms required for the environment
the machine is installed in.
It is not suitable for work in open air areas, corrosive, explosive or excessively dusty
environments.
Don’t touch any voltage carrying parts.
Do not damage, tamper with or tread on the connection cables.
The webguide WG251 SKB-B RESMART includes moving parts so it is fitted with
special guards to stop anyone from crushing their hands. In any case, always take care
and do not touch moving parts.
During installation and use, remove bracelets, watches and other items from arms and
hands which may catch on moving parts and secure loose clothing.
Beware of the material that runs on the webguide as it could cut you!
When handling the webguide always wear safety gloves and boots
and observe all the safety norms required for the environment in
which it is located.

Assembling the webguide on the end machine
1) Fit the SU m-25 sensor on the webguide sensor holder bar:
Application with a micrometer bar (the SU m-25 sensor is already fitted on the micrometer
bar)
Fit the micrometer lock onto the sensor holder bar so that the outer side of the securing
bracket is aligned with the outer side of the sensor holder bar.
Tighten the two dowels under the securing bracket.
Screw up the positioners inserted in the slide until they are resting on the bar and then lock
them in place with the two nuts.
(All the locking elements are supplied already inserted in their relative housings)
To assemble the webguide wear safety gloves and boots and observe
all the safety norms required for the environment in which it is
installed.

Application without a micrometer bar
Fit the slide onto the sensor holder bar so that the sensor is in the required position
according to where the material will run.
Tighten the knob located under the sensor.
2) Fasten the WG251 SKB-B RESMART webguide to the machine structure using the 4 holes on the
external box support table using 4 x M6x10 screws (not supplied with the webguide).
The direction of the guide should be fixed according to the direction the material will run in (the
arrow on the frame of the webguide indicates the material feed direction).
Check that the infeed and outfeed machine rollers are parallel and on the same plane as the
webguide rollers.
Assemble the guide observing the safety distances between the webguide and the rest of the
machine, as stipulated in current normatives
Caution! It is important to secure the webguide before connecting it up electrically;
when making the electrical connections follow the instructions in the following section.

Attention!
To ensure this instrument functions correctly, wait for at least 5 seconds between
switching it off and switching it on again.
Important!
Use shielded power supply cables only, and connect the shield to the earth point
located on the MWG10 unit. The earth point (represented in the drawing), must be
connected to the machine frame by a cable, that must be as short as possible; the
cable section must be 6mm2minimum.

Sensor positioning
Caution!
When calibrating or using the webguide, if you need to adjust the
position of the sensor we strongly advise you to make the adjustment
when the webguide and the material are NOT moving!
Application with a micrometer bar
Move the sensor by turning the micrometer bar knob until the required position is reached.
Application without a micrometer bar
Slacken the knob located under the sensor.
Move the sensor until it reaches the required position.
Screw up the knob to lock the sensor.
