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 H
(0685.2 ...) model series are electri c mo tor driven paper cut ters. The paper
is cut by a double-edged rotary knife. Thus two cuts can be made per one
single turn of the knife. These models allow the following triggering of the
drive motors:
K = Cutting is triggered by applying nominal voltage
via mechanical SPDT contacts
The cutters of these model series are avai l a b l e i n var i o us vers i o ns,
depending on the paper width and the operating voltage.
Safety Instructions
This cutter is a q ua lity product manuf actured in accorda nce w ith
established electrical engi neer ing standards. The unit has been del i ver ed
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 electrot echnical 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 co mplying with EN 60950, pro tection class III.
To prevent dangerous structure-borne current s, t he 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 o p e r a ting 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 rotary knife has two sharp cutting edges! Therefore never r each
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
• Do not cut self-adhesive labels! The traces of adhesive will pollute
the rotary knife and impair safe operation!
• During the cutting process, there must be no paper feed.
• Please make sure that the cutter remains free from shreds of paper.
• Having applied voltage, please ensure that the rotary knife is in home
position before paper is fed.
• If the cutter doesn’t have internal switching (page 3 of 4), the user
must install a suitable safety switch to ensure that power is removed
from the cutter within a max. of 10 seco nds in the event of a breakdown, such as a jammed cutter. If this is not done, the motor may be
damaged through overheating.
• Do not use cleansing ag ents containing solvents.
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 colle ct in the cutting area, thus blocking the
rotary 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 3 ”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
(please observe the key of fig. „Designation of parts“ on page 2)
• Make sure that the cutter is turned off. Slide the paper in the paper
feed direction indicated (10) through the paper channel (2).
If the rotary knife (3) is not in home position it will hinder the paper
strip from being slid through the channel.
You can put the rotary knife to home position in two dif f e r e nt ways:
1. Insert a hex key, size 3, into the rotary knife’s shaft (7) and turn the
knife until it does not block the channel any lo nger. Then remove the hex
key from the shaft!
2. Turn on the assembly and cond uct 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.
