Safety
The European standard EN 60204-1 requires the power
supply connection to be established by a suitable plug
device. The power supply cable must not be connected to a
power distributor directly by way of a terminal connection,
without a plug connector.
Safety limit switch S1 prevents the machine from starting up
when the machine hood is open. This safety device must be
checked before putting the machine into operation each
time to make sure it is fully functional.
Procedure:
First switch on the machine and wait for the reference run to be performed
(see last paragraph below), open the hood, do not reach into the machine
(!), then press the foot pedal. The machine must not start up.
Caution! Risk of crushing! Checking the safety mechanism
During downward movement, the RBM-10-310 toothed rack has an electro-mechanical
safeguard. If the RBM-10-220 needle shoe touches any object above the worktop, the
drive motor gets immediately reversed and the rack moves up into the starting position.
To check this safety mechanism, lay a sheet of paper over the worktop opening. Now
start the machine by pressing the pedal. If this process damages the sheet of paper, the
safety mechanism needs checking (see procedure on page 12). The manufacturer
recommends performing this test on a daily basis.
Always pull the mains plug before maintenance and cleaning
work!
When inserting a new string bobbin, and when threating the
string, always pull the mains plug.
A minimum of 500 lux is required for local lighting.

Siebeck GmbH 0perating manual rbm-bed-0910
Page 9
Set-up and commissioning
Erect the machine in the designated location and press the wheel locks
down so that the machine is stable.
To avoid collisions with other machines and to ensure operating
and maintenance staff have sufficient access, there must be
minimum of 1.5 metres of clearance around the entire machine.
If not otherwise stipulated, the machine is designed for 230 V 1-phase
alternating current 50/60 Hz when supplied from the factory. Measure
the local mains voltage and compare the measurement with the value
specified on the type plate.
Check that the machine is correctly grounded. Adhere to the local
electrical engineering regulations. Maximum fuse protection 16
amperes. Connect the machine to the supply mains using a plug
connector. Switch on the master switch. The indicator lamp lights
up.
Checking the motor's rotary direction
The machine is fitted with a device to monitor the direction of rotation
(phase sequence relay).
Using the mains plug, connect the machine to the electricity mains. Turn
on main switch. After c. 5 seconds the control light glows solidly, thus
signalising that the direction of rotation is correct. The machine is ready for
use.
If the control light does not come on, the phase sequence is wrong. The
monitoring device cuts off the supply of electricity. For the correct direction
of rotation you need to switch two phase lines inside the mains plug.
Tying material
The knotting mechanism is designed for a maximum material thickness of
900 linear metres per kilogram (ELA-900). It is recommended that during
the warranty period you purchase the material from the machine
manufacturer. This avoids any potential loss of your right to make a
warranty claim that incorrect material use may cause.

1. Insert the string bobbin into the string container (A) and press
firmly against the foam rubber pad (B).
2. Feed string through the hole (C) in the flat bar, under the brake
plate (D) and through the hole (E).
3. Feed through between the brake bracket and brake plate (F).
4. Thread from front to back into the five string rollers, starting at 1
and in sequence up to 5, and then through the hole (G) in the
needle arm.
5. Using your right hand, pull the end of the string further up to the
right, rear corner of the worktop and secure it there.
6. Actuate machine (after enabling it as described on page 14) via
the foot pedal. The string then gets automatically deployed under
the worktop and cut off.
Caution, risk of crushing!
The opening in the middle of the worktop must be kept clear!
When the needle dips in, there is a significant risk of injury
here.

Correct positioning of the products to be tied up
1. For the first and each subsequent binding the products to be
tied up should be fed until over the guide edge marked on the
worktop (see illustration below).
2. After the first binding, the products get fed further to the right
and once again until nearly over the guide edge.
Should tying up the product twice not suffice, the process
needs to be repeated.
3. If the product gets pushed beyond the guide edge, the binding
will be loose. If the product gets fed just short of the guide
edge, the binding will fail / the string will snap.

Checking the safety mechanism
(Enabling)
Caution! Risk of crushing!
During downward movement, the RBM-10-310 toothed rack
has an electro-mechanical safeguard. If the RBM-10-220
needle shoe touches any object above the worktop, the drive
motor gets immediately reversed and the rack moves up into
the starting position.
After switching on, the machine's start-up is blocked. This block
also becomes automatically active if the machine is not used for
over an hour. This start-up block is indicated by a flashing a
control light.
In order to enable the machine, you need to push the (yellow)
RBM-10-220 needle shoe gently with your flat palm up as far as it
will go and then let go again. Do not use any force! The needle
shoe must allow itself to be pushed up easily and automatically go
back to the starting position.
This procedure checks every element of the integrated safety
mechanism. If all is functioning properly, the machine gets
enabled. The control light glows solidly and the machine is ready
for use.
If the machine does not get enabled, the following checks should
be made:
1. Switch off machine.
2. Unscrew covering panel on the needle arm.
3. Check that the needle shoe moves easily. If necessary, clean
and oil.
4. Check that the RBM-10-470 securing plate is firmly in place.
5. Check that the RBM-50-030 monitoring switch is firmly in place
and working properly both electrically and mechanically.
6. Check that the RBM-10-210 contact is at the correct distance
from limit switch lever and firmly in place.
7. Check that the RBM-10-290 adjusting collar is firmly in place.
Only authorised and traind staff is allowed to perform this
chec-up!

The story of knots
Incorrect knotting
patterns and their
causes
Short loops
The knotter opens too early. Shift the mount for
the cam roller for opening the knotter backwards
towards the chain wheel. The stripper does not
rest on the knotter. The string is too thin.
Knots not strong enough
Stripper slot too large. The knotter opens too
early. The string is too thin.
String not cut cleanly
The string knife is blunt. Flip or replace the knife.
String break before the knot
Sharp edges on the stripper, drawslide head, tip
up lever or knife lever.

One loop of normal length, one loop which is too short
The knotter is not closing properly. Tension
spring for the knotting lock is too weak. The
stripper does not rest on the knotter.
Single loop
The knot has only a single loop. The second
loop is drawn through. Increase the spring
pressure on the twine button. The lead end of
the string which protrudes from the twine button must not move when the
tying arm starts up.
Loop ends torn
Upper or lower finger of knotter or stripper has
sharp-edges.
The perfect knot
A correct knot has two loops of equal
length and one short and one long end of
string. The knot is tight and hard.

Siebeck GmbH Operating manual rbm_bed_0910

Faults and their causes
Never rework the surface of the twine button housing! This
surface has an exactly specified contour. The notch is
intentional and has not been created by wear. Only ever
make the necessary settings by adjusting the string brake and
twine button spring.
1. Threading: Make sure that threading has been performed
properly.
The string taking the wrong course is the most common cause of
string breaks (see "Inserting the string" on page 10).
2. String: The machine is set to a certain string thickness.
Always use the same quality and thickness of string in order to achieve
the best results.
a) String which is too weak often breaks on the twine
button instead of being pulled out without hindrance
b) If the string is too thick, it will not be released by the
knotter
c) String which is too thin causes a loose knot
3. Twine button: If you are using a good quality of string of the
correct thickness and it still breaks and leaves behind residual fibres in
the twine button, this is generally caused by excessive spring tension on
the twine button.
Reduce the spring tension. Make sure that the setting wheel re-
engages properly and the retainer screw is tightened.
4. String tension: You achieve the best results with an even,
smooth string brake setting. Check the setting by pulling out a few
metres of string from the tying arm tube. You can change the string
tension by turning the knurled nut on the string brake.
Every person on the user's premises given the task of
setting up, commissioning, operating, maintaining and
repairing this machine must have read and understood
this operating manual, and in particular the chapter
"Safety".

Residual risks and incorrect operation
Residual risks and incorrect operation which exist despite measures for
integrated safety and technical protective equipment, are described and
illustrated in the following. These risks are documented in a risk analysis
and filed by the manufacturer.
With the worktop unscrewed, it is possible to advance the knotting
aggregate step by step via the push button (jog mode). The individual
movement processes can thus be well observed.
Jog mode:
Only authorised and trained staff is allowed to
perform this procedure.
In the entire area of the knotting aggregate, in particular on its
drive elements, between the chain wheel and roller chain , and
between the trigger and the frame, there is a considerable
risk of crushing.
Caution, risk of crushing!
The opening in the middle of the worktop must be kept clear!
When the needle dips in, there is a significant risk of injury
here.
Thermal hazard!
The drive motors M can reach temperatures of up to 80°C.
When the sections of panelling are removed, contact can
cause injuries.
