3 General description and use for the purpose intended
3.1 General description
Bi-cord conveyors are ideal for soiled table-
ware return.
The linear attachements of the polycord
leaves virtually the whole of the conveyor
surface free.
This type of soiled tableware return is greatly
favoured because it allows transport of en-
tire only, and not of individual tableware
items (plates, cups, cutlery, bottles etc.),
preventing them from failing off the conveyor
in bends or curves abd thus ensuring high
levels of safety.
Bi-cord conveying technology makes any type of cornering possible.
Speeds alterations ensure the safe, centered and properly distanced transport of the
around bends.
Maintenance free deflection rollers glide with minimum wear the bi-cords around all cor-
ners provided with sturdy elevated tray guides which prevent the tableware from falling
off the conveyor.
3.2 Determined use
DANGER!
This transport system is determined to transport trays with dishes, other kind of use is not
allowed.
This belt conveyor is intended solely for use in a commercial environment.
If not otherwise agreed, the transport system can be loaded with up to 5 kg/m.
The max. speed is 20 m/min.
The admissible dimensions of trays indicated in the chapter „Technical conditions“, and all
other technical specifications must be observed without exception.
If the round belt transport system is not used acc. to it’s determination a safe operation
cannot be guaranteed!
For all injuries and damages to property arising of the non-determined use, not the manu-
facturer, but the operator of the round belt transport system is responsible.

6 General safety rules
6.1 Operator’s duty of care
CAUTION!
The round belt transport system was designed and constructed under consideration of a
danger analysis and a careful selection of the harmonized standards to be observed as
well as of further technical specifications. The system corresponds to the latest state of
technique and guarantees maximum safety.
The safety can only be guaranteed during operation if all necessary measures are taken.
The operator’s duty of care comprises the planning of these measures and the supervision
of their observance.
After the installation, setting in operation and handing-over of the round belt transport sys-
tem to the customer/operator further modifications are not allowed (f. ex. electrcial change-
ments or changements reg. location). Any modifications to the round belt system without
the written approval of MEIKO or undertaken by unauthorized persons will invalidate any
right to claim and product liability.
CAUTION!
The operator must especially make sure that...
... the round belt transport system is only used acc. to its’ determination.
In case of other use or operation, damages or danger may arise for which we decline any
responsibility (cf. chapter „Determined use“).
... function and safety are guaranteed by using original parts from the manufacturer.
The user loses all evtl. claims if the system was altered with others than original spare
parts.
CAUTION!
... only sufficiently qualified and authorized personnel operates, maintains and repairs the
system.
CAUTION!
... the personnel is regularly instructed regarding working safety and environmental pro-
tection, and that the operation instructions and especially the safety regulations are known
to them.
CAUTION!
... the system is only operated in perfect, operationally efficient condition, all safeguards
and cladding panels are installed, and, in particular, that the safety systems and switch
elements are regularly checked for their operational efficiency.

10.7 Jam switch option
JAM SWITCH option with the CONTINUOUS OPERATION - QUEUE OPERATION toggle
switch
If CONTINUOUS OPERATION operating mode is selected, all drive motors are active and
are permanently driven by the control system.
QUEUE OPERATION is only recommended during quiet times for the pot wash.
No people are needed at the washware clearing stations to clear the washware in progress.
When selecting QUEUE OPERATION, only the drive motor of section 1 (tray feed) is per-
manently controlled. At the end of this drive a light key is integrated into the conveyor belt.
If a tray actuates this light key, the drives of section 2 are activated for a time set via a time
relay.
This time corresponds to the crossing distance and the tray distance from section 1 to the
continuing section 2 of the bi-cord conveying system. Once the set time has elapsed, sec-
tion 2 stops again.
Proceed in this way with each additional tray until the first tray in the dishwashing area is
at the height limitation. This control system creates a row of trays at narrow intervals.
Then a hoot will sound to indicate the situation. This signal can be switched off by pressing
the toggle switch to CONTINUOUS OPERATION.

When at the additional sockets with 230V / 400V voltage are provided on the bi-cord con-
veying system, a suitable residual current circuit breaker is installed in the control cabinet
of the bi-cord conveying system for these sockets. The sockets are designed to meet the
IPX5 requirement. A product from the company Marechal is thus used. A matching plug is
supplied with each socket.
10.10 Position and level indicator
With the position and level indicator, the absorbed empty trays are guided onto a tray dis-
penser trolley at the end of the bi-cord conveying system and deposited there.
To detect whether a tray dispenser trolley is present, it is scanned via a light key on the
positioning device.
A second light key detects the height of the trays on the tray dispenser trolley and signals
the imminent full signal of the tray dispenser trolley by a yellow lamp at the control panel.
If there is no tray dispenser trolley, the yellow lamp also lights up and the bi-cord conveying
system stops. As soon as a tray dispenser trolley is moved into the positioning device and
positioned at the correct location, the bi-cord conveying system starts up again automati-
cally.
An additional buffer is available as an option for this version. This is automatically extended
as soon as the tray dispenser trolley is moved away after full signal.
This buffer is also monitored by a light key.
Only when a defined quantity of trays has accumulated does the bi-cord conveying system
stop.
By pushing an empty tray dispenser trolley into the positioning device, the buffer is pushed
back into the belt body of the bi-cord conveying system. After correct positioning, the bi-
cord conveying system starts up again automatically.
10.11 Connection to BTA machines
There are 3 versions for the connection to BTA machines:
Version 1:
The BTA machine provides a potential-free contact that needs to be integrated into the
control system of the bi-cord conveying system. If the BTA is ready for operation, then the
bi-cord conveying system may also run.
If the BTA machine switches off the machine transport, the entire bi-cord conveying system
stops.
Version 2:
In addition to the potential-free contact of the BTA machine, a light key is installed at the
end of the bi-cord conveying system.
If the BTA machine now switches off the machine transport, the bi-cord conveying contin-
ues to run until a tray moves onto this light key. The bi-cord conveying system then stops.
Version 3:
This function is the same as for version 2.
However, a photoelectric barrier is installed at the end of the bi-cord conveying system
instead of the light key. This photoelectric barrier also measures the distance between the
trays. If two trays pass this photoelectric barrier in direct succession, the bi-cord conveying
system is switched off briefly (approx. 0.5 sec) after the first tray has passed, thus creating
a gap between the trays in the BTA machine.
