– ECC-DFC field bus controller
As soon as the first box has passed the vicinity of the photo sensor, the gap timer
starts. The next box arrives in the discharge zone and is stopped there until the
gap timer has elapsed. When the gap timer has elapsed, the discharge zone is
released and the train of boxes in all 10 upstream zones will start to move again
simultaneously.
If you choose “Gap Train” in the “ZPA Mode” drop-down menu, the “Gap Timer”
input field and the “Set” button are activated. Enter the required time value and
click “Set” to update the value in the selected node.
INFORMATION
Gap Train mode is designed for use in the discharge zone of a zone group that is
in train mode. If several successive zones are configured as Gap Train, a wait
will occur in each of these zones for the duration of the respective Gap Timer.
Depending on the time setting, the result may be very similar to “Singulation”
mode.
T-bone configuration
In conveyor applications, special raising and lowering mechanisms are often
needed to transfer a load at right angles from one conveyor belt to another. In
other applications, a conveyor can simply transport its load from its downstream
zone directly into the upstream zone of another conveyor arranged at a right an-
gle. This configuration is generally known as a T-bone arrangement.
The ECC-DFC fieldbus controller contains the logic for controlling a T-bone ar-
rangement without the need for an external controller interface or programming.
Figure 34 shows the type of T-bone arrangement that is possible with the ECC-
DFC fieldbus controller without an external interface.
