Safety Instructions and Responsibility
General Safety Instructions
This operation manual is a significant component of the unit and includes important rules and
hints about the installation, function and usage. Non-observance can result in damage and/or
impairment of the functions to the unit or the machine or even in injury to persons using the
equipment!
Please read the following instructions carefully before operating the device and observe all
safety and warning instructions! Keep the manual for later use.
A pertinent qualification of the respective staff is a fundamental requirement in order to use
these manual. The unit must be installed, connected and put into operation by a qualified
electrician.
Liability exclusion: The manufacturer is not liable for personal injury and/or damage to property
and for consequential damage, due to incorrect handling, installation and operation. Further
claims, due to errors in the operation manual as well as misinterpretations are excluded from
liability.
In addition the manufacturer reserve the right to modify the hardware, software or operation
manual at any time and without prior notice. Therefore, there might be minor differences
between the unit and the descriptions in operation manual.
The raiser respectively positioner is exclusively responsible for the safety of the system and
equipment where the unit will be integrated.
During installation or maintenance all general and also all country- and application-specific
safety rules and standards must be observed.
If the device is used in processes, where a failure or faulty operation could damage the system
or injure persons, appropriate precautions to avoid such consequences must be taken.
Use According to the Intended Purpose
The unit is intended exclusively for use in industrial machines, constructions and systems. Non-
conforming usage does not correspond to the provisions and lies within the sole responsibility
of the user. The manufacturer is not liable for damages which has arisen through unsuitable
and improper use.
Please note that device may only be installed in proper form and used in a technically perfect
condition - in accordance to the Technical Specifications (see chapter 11). The device is not
suitable for operation in explosion-proof areas or areas which are excluded by the EN 61010-1
standard.

Fs340_02b_oi_e.docx / Nov-21 Page 6 / 49
Installation
The device is only allowed to be installed and operated within the permissible temperature
range. Please ensure an adequate ventilation and avoid all direct contact between the device
and hot or aggressive gases and liquids.
Before installation or maintenance, the unit must be disconnected from all voltage-sources.
Further it must be ensured that no danger can arise by touching the disconnected voltage-
sources.
Devices which are supplied by AC-voltages, must be connected exclusively by switches,
respectively circuit-breakers with the low voltage network. The switch or circuit-breaker must
be placed as near as possible to the device and further indicated as separator.
Incoming as well as outgoing wires and wires for extra low voltages (ELV) must be separated
from dangerous electrical cables (SELV circuits) by using a double resp. increased isolation.
All selected wires and isolations must be conformed to the provided voltage- and temperature-
ranges. Further all country- and application-specific standards, which are relevant for structure,
form and quality of the wires, must be ensured. Indications about the permissible wire cross-
sections for wiring are described in the Technical Specifications (see chapter 11).
Before first start-up it must be ensured that all connections and wires are firmly seated and
secured in the screw terminals. All (inclusively unused) terminals must be fastened by turning
the relevant screws clockwise up to the stop.
Overvoltages at the connections must be limited to values in accordance to the overvoltage
category II.

EMC Guidelines
All motrona devices are designed to provide high protection against electromagnetic interference.
Nevertheless you must minimize the influence of electromagnetic noise to the device and all
connected cables.
Therefore the following measures are mandatory for a successful installation and operation:
•Use shielded cables for all signal and control input and output lines.
•Cables for digital controls (digital I/O, relay outputs) must not exceed a length of 30 m and
are allowed for in building operation only
•Use shield connection clamps to connect the cable shields properly to earth
•The wiring of the common ground lines must be star-shaped and common ground must be
connected to earth at only one single point
•The device should be mounted in a metal enclosure with sufficient distance to sources of
electromagnetic noise.
•Run signal and control cables apart from power lines and other cables emitting
electromagnetic noise.
Please also refer to motrona manual “General Rules for Cabling, Grounding, Cabinet Assembly”.
You can download that manual by the link

Cleaning, Maintenance and Service Notes
To clean the front of the unit please use only a slightly damp (not wet!), soft cloth. For the rear
no cleaning is necessary. For an unscheduled, individual cleaning of the rear the maintenance
staff or assembler is self-responsible.
During normal operation no maintenance is necessary. In case of unexpected problems, failures
or malfunctions the device must be shipped for back to the manufacturer for checking,
adjustment and reparation (if necessary). Unauthorized opening and repairing can have
negative effects or failures to the protection-measures of the unit.

Available Models
The two models as shown below are available. Both models are fully similar in terms of
function and performance; however there is some difference with the size, the alert outputs
and the speed ratio setting.
FS340:
▪Front size 96 x 48 mm (3.780’’ x 1.890’’)
▪Cutting length setting by keypad
▪Analogue output 14 bits
▪4 power transistor outputs (alert)
FS641:
▪Front size 96 x 96 mm (3.780’’ x 3.780’’)
▪Cutting length setting by keypad
or by front thumbwheel switches
▪Analogue output 14 bits
▪4 power transistor outputs (alert)
▪and 4 relay outputs (alert)
Both models are suitable for front panel or operator desk mounting, by means of the included
mounting clamps.
Where you desire to mount the units on DIN rails inside a cabinet, please refer to the mounting
brackets type SM 300 and SM 600 available as accessories.

Introduction
The FS340 / FS641 units are suitable for control of “Flying Shears” and “Flying Saws”,
frequently used for cut-to-length applications with endless material, where the material is in
continuous motion and cannot be stopped during the cutting process.
The mechanical construction provides a carriage with a cutting tool, following synchronously
the material while the cut is in progress, and then returning to a home position, to wait for the
next cut.
The FS340 / FS641 units have been designed for the special requirements of flying shear
systems, under consideration of maximum efficiency and accuracy, with minimum stress for all
mechanical parts. Very short control cycles together with intelligent motion profiles provide
excellent performance under all operating conditions.
This unit is very easy to set up. All settings can be made either by keypad and display at the
unit or by PC, with use of the motrona operator software OS10.
All relevant operational parameters and variables are accessible by RS232/RS485 interface. For
PROFIBUS applications, our PB251 gateway is available. Therefore the user has multiple
possibilities for remote control of all batch and cutting parameters via operator terminals, PC or
PLC systems
•This manual first provides all basic instructions for operation of model
FS340
•For operation of relays and thumbwheels with model FS 641 see appendix
•For PC setup our “OS10” software is available on the USB stick included to
delivery, or on our homepage www.motrona.com
•For communication by PLC or IPC or by a remote operator terminal, please
observe the serial protocol details described in our separate manual
“Serpro”.
•PROFIBUS communication is possible with use of our gateway PB251.
