address:
2. The pump needs to be restarted to initialise the
new bus address. Switch off the power supply of
the pump and wait for approximately 20 seconds.
3. Switch on the power supply of the pump.
The pump is initialised with the new bus address.
7.17.5 Characteristics of bus communication
To start and stop the pump via bus, it needs to be in
operating state "Running". When the pump is
remotely stopped from bus, the "
External stop
"
symbol is displayed and the pump switches to
operating state "Standby".
While bus control function is activated, the "
Setup
"
menu only shows the "
Bus
" and "
Key lock
"
submenus. The other main menus, the "
External
stop
" function and the keys are still available.
All operation modes (see section
) can still be used when bus control is
activated. This allows to use the bus control only for
monitoring and setting the pump. In this case the
respective "
BusWatchDog
" (see functional profile on
CIM/CIU product CD) should be deactivated in bus
control, because otherwise faults in communication
can stop the pump.
7.17.6 Deactivate communication
After deactivating the bus control function, the pump
can start automatically.
Bus control function can be deactivated in the "
Setup
>
Bus
" menu. After deactivation all submenus in
"
Setup
" menu are available.
The "Bus" symbol in the display disappears at next
restart of the pump, after the CIU plug was
disconnected.
7.17.7 Communication faults
Faults are only detected, if the respective
"
BusWatchDog
" (see functional profile on CIM/CIU
product CD) is activated.
After a communication fault is repaired, the pump
can start automatically, depending on current bus
control and pump settings.
In case of bus communication faults (e.g.
communication cable break), the pump stops dosing
and switches to operating state "Standby"
approximately 10 seconds after the fault was
detected. An alarm is triggered, detailing the cause
of the fault. See section
.
