Introduction
This installation manual is provided for the connection and starting
procedure of your cutter.
Further informations like e.g. dimensioned drawings are available in our
Printers and Cutters Catalogue or on request. The devices of the type L
(0685.74 ...) model series are electric motor driven paper cutters. The paper
is cut by two flat knives. Cutting is monitored by an internal microswitch.
Cutting is triggered by an external SPDT contact. The cutters of these
model series are available in various versions, depending on the paper
width and the operating voltage.
Safety Instructions
This cutter is a quality product manufactured in accordance with
established electrical engineering standards. The unit has been delivered
from the factory in perfect conformance to safety regulations. To maintain
this condition, please observe all notes and warnings in this document!
•Installation and mounting of electrical devices may only be
performed by an electrotechnical expert!
•When installing and mounting the cutter, please observe the
demands made on the whole facility by the respective device safety
regulation.
•The cutter may only be used for the purpose it was designed for – i.e.
for cutting paper strips.
•The cutter is designed complying with EN 60950, protection class III.
To prevent dangerous structure-borne currents, the equipment has to
be run on safety extra-low voltage (SELV) and must be in an area of
equipotential bonding.
•The cutter may only be operated within the limits specified by the
technical data. Maximum operating voltages must not be exceeded!
•Hengstler Cutters are designed for industrial use.
•Installation environment and cabling have a very significant
influence on Electromagnetic Compatibilty (EMC). When installing
the cutter sub-assembly in a complete unit, you should seek
guarantees from the manufacturer of the complete unit regarding
EMC.
Caution: Danger!
•The flat knives has two sharp cutting edges! Therefore never reach
into the cutting area, e.g. for removing jammed material! Only use
tweezers, tongs or the like for this purpose (do not damage the
knife)!
•It is expressively emphasized that the cutter is to be started only
when completely installed, i.e. the knife is covered on all sides and
the material feed and delivery slot are dimensioned such that, e.g.,
small children cannot reach into the cutting area.
•Installation or servicing works are to be carried out only when the
power supply lines are disconnected from the cutter!
•If safe operation is not possible any more, the cutter has to be set out
of order and to be protected against unintended starting.
Operating Instructions
•During the cutting process, there must be no paper feed.
•Please make sure that the cutter remains free from shreds of paper
and that the strips must be taken out after cutting and before the
next strip is cut.
•Having applied voltage, please ensure that the knives are in home
position before paper is fed.
•The cutter doesn’t have internal switching (page 2), so the user must
install a suitable safety switch to ensure that power is removed from
the cutter within a max. of 10 seconds in the event of a break-down,
such as a jammed cutter. If this is not done, the motor may be
damaged through overheating.
•Do not use cleansing agents containing solvents.
•When cutting linerless material there can be accumulations of glue
on the flat knife. This does not affect the cutter´s performance.
Installation Instructions
•The cutter must be installed in the intended unit before connecting
the power lines!
•The cutter can be installed in any position. The strips cut off,
however, must not collect in the cutting area, thus blocking the flat
knife!
•The cutter is attached by means of two M3 screws.
•Install the cutter in the unit/housing such that paper transport is
smooth. Electrically connect the cutter to the control system and
power supply when these are switched off. You will find the
connection diagrams of this model series on page 2 ”Connection
diagram” and on the units’ backs.
•Wire the cutter’s connecting lead, such that it does not disturb any
function of the assembly and that it will not be damaged or
squeezed.
Preparations for use
•Make sure that the cutter is turned off. Slide the through the paper
channel in the paper feed direction indicated.
If the knives are not in home position they will hinder the paper strip
from being slid through the channel.
You can put the knives to home position in two different ways:
1. Turn the shaft screw on the outside of the case using a flat screwdriver
until the channel is clear.
2. Turn on the assembly and conduct one cutting cycle without paper.
Perform a trial run with paper.
Ensure that the paper strips are fed to the cutter continuously and
properly and that the unit cuts them precisely.
