Product description
The ZoneControl is used to facilitate zero pressure accumulation conveying, meaning that goods are transported
without coming into contact with each other. To achieve this, the conveyor is sub-divided into zones. One zone consists
of a RollerDrive, several idler rollers, a ZoneControl and corresponding sensors.
Zero pressure accumulation conveying is achieved by there being only one product in every zone and by the zones
retaining the package until the downstream zone is detected as being „free” by the corresponding sensor. When
accumulation occurs, a signal is transmitted upstream to retain the next package. A gap is always left between the
goods being transported so that no accumulation pressure occurs.

10 Package
The sensor in zone 1 has detected a package. The ZoneControl in zone 1 sends a request to zone 2 to ask whether
the package can continue to be conveyed. Since zone 2 also contains a package, its ZoneControl denies permission
until this package has been transferred to zone 3 (singulated release mode) or at the very least its onward transport
has been started.
In singulated release mode, the package is only conveyed on if the package in the downstream zone has fully left
this zone. In train release mode, the packages are virtually transported simultaneously (with a time delay of approx.
125 ms to reduce peak current when starting up.)
The ZoneControl in zone 1 only activates the RollerDrive in this zone after it receives the corresponding signal from
the ZoneControl in zone 2.
