7.8. Network error
In cases where the Ethernet network connection between the modules of the
fieldbus controller is interrupted during operation, loads continue to be transport-
ed and jam in the downstream zone that is furthest from the location where the
network has been interrupted. This furthest downstream zone will automatically
jam the load and not allow any further transportation in the downstream flow di-
rection. As soon as network communication is restored, the zone returns to nor-
mal operation.
7.9. Low voltage fault
In cases in which the controller detects that its supply voltage has dropped below
DC 18 V, it will put its configured zone(s) into jam mode. The controller will retain
this condition until it has determined that its input voltage has increased to at
least DC 21 V.
NOTICE!
Repeated temporary stopping or delaying of normal zone-to-zone movement
may be an indication of low voltage.
If this behavior is observed continuously, measure the voltage at the point that is
furthest from the current supply unit and check the dimensions of the current
supply and the wiring techniques in order to ensure that the correct voltage is
provided at all modules.
INFORMATION
The ECShell engineering software has several diagnosis functions. These can
be used to determine how often the current supply has dropped below DC 18 V.
This can assist with finding electrical problems in the system.
7.10. Automatic module replacement
If a linear conveyor with auto configuration has been started up, the modules of
the fieldbus controller store the configuration data of their neighboring modules.
This configuration data is updated automatically, even if the parameters of the
linear conveyor are modified by the ECShell engineering software. The firmware
of the ECC-DFC uses this function for easy module replacement, so that the en-
tire linear conveyor system does not have to be reconfigured if a single module is
replaced.
INFORMATION
Automatic module replacement is used to replace modules in systems with sev-
eral subnetworks. It is not necessary to temporarily interrupt network connections
or isolate the subnetwork in which the replacement is going to take place.
