Function
The labelers receive their starting signal via the product sensors (see Fig. 7-15).
 Product sensor 1 detects the product which is then labelled by the master system.
The slave system receives a corresponding information and ignores the already la-
belled product if this is detected by the product sensor 2.
or
 Product sensor 1 detects a product that is not labelled by the master system (e.g. end
of roll). The slave system receives the corresponding information and expects the
product sensor 2 to detect the product after a certain distance; the slave system then
labels the product.
When controlled by a PLC, both labelers also require a start signal for each product, as is
normally provided by the product sensors. This means that if a product is at the dispens-
ing edge of the master system, the master system receives a start signal. If the same
product reaches the dispensing edge of the slave system, the slave labeler also receives
a start signal.
An unlabelled product can be introduced into the conveyor system not only before the
master system but also before the slave system (between the labelers). The slave system
then labels this product because no information has been sent from the master system.
The individual operating states of the labelers can be displayed via a 3-colour signal lamp.
Prerequisites
 Two labelers
 Both labelers receive their start signal via their own product sensor or via the PLC
(connection of the labelers with the PLC is established via the respective product
sensor input).
 Connection of the two labelers is performed via the network connection (X20
"Ethernet", see page45).
 A rotary encoder that is connected to both labelers by means of a splitter box or...
one separately connected rotary encoder per labeler
Setting the ZeroDownTime / alternating operation
Incorrect parametrisation can lead to process and function er-
rors that can also cause mechanical damage.
This also applies for changes to reserved or undocumented
parameters, as well as a parametrization which is beyond the
valid parameter range.
- The parametrisation may only be conducted by trained per-
sons!
The machine parameter 023 “ZeDoTime Mode” is used to set whether labels are labeled
in the ZeroDownTime mode or alternating operation.
