Ecolab Smart Dose II Rack Manuel D'utilisation page 78

Description of Operation
If the controller also includes a dosing signal that comes in via one of three possible
inputs, then this impulse is passed on to the correct TurboSmartPump II. The pump will
start the metering procedure independent of the stored washing program parameters. This
procedure is continued until the proper dosing quantity has been reached.
The display will show a pump's metering procedure next to the active pump number.
The display will also show an "animated" arrow that will show which pump is currently
active.
Metering pumps (pos. 8 - 11) feed the product into the connected manifold. The product
then leaves the manifold where it is fed into the machine and rinsed with water.
Using a manifold has two advantages:
n Less time required for installation and lower installation costs since only one metering
line to the machine is required.
n Product concentration is reduced due to water being incorporated to ensure that the
washing procedure is gentle on the objects being cleaned.
A post rinse takes place after the metering has been completed. All of these steps ensure
that all of the required product quantity ends up in the washer, in order to achieve
excellent washing results.
There are two options for parameterizing the water flow:
Purging: Water is released in addition to metering.
n
n Post-rinse: Each time dosing has ended, the dosing line is rinsed out with water.
A solenoid valve (pos. 5) is used to control the water intake. The solenoid valve is
connected to the controller.
To guarantee optimum process stability, a through-flow monitor (pos. 6) checks the stream
of water. The controller sounds an acoustic alarm if the water does not flow. If this occurs,
the water supply must absolutely be inspected.
The product-empty signal is another technical means of supporting the washing process.
The empty-signal float (pos. 13) that is connected to the suction pipes (pos. 15) generates
the signal.
The empty-signal float follows the product level as it drops within the product supply
container. The controller (pos. 3) emits an acoustic signal if the contact for the
empty-signal float is broken.
When the acoustic signal sounds, it is time to change the supply container.
The empty alarm sounds from its location on the lowest, most outer location on the
suction pipe to ensure the all residual material has been emptied out of the supply
container.
The Smart Dose II Rack's function described above outlines an overview of the safety
function that is implemented. There is also an illustration showing how these functions
have been integrated into the metering procedure's process cycle.
These technical monitoring processes ensure the Ecolab's proprietary, high degree of
dosing process safety and guarantee you, the customer, with smooth, everyday operation.
