Dispensing sys-
tem setup
Set up dispensing system is used to calibrate the dispensing systems.
This must be performed if:
- The connected process chemical has been changed (different vis-
cosity).
- A new dispenser pump or a new flow sensor has been installed
- The dispensing system needs to be checked, e.g., in the event of
qualification, requalification, or a periodic check.
During setup, the dispenser pump is activated for a defined number
of pulses. In parallel to this, the control module counts the pulses
emitted by the flow sensor. After the measured volume has been en-
tered into the control module, the module calculates the conversion
factors for the throughput of the dispenser pump in µl/Imp and the
pulse rate of the flow sensor in µl/Imp.
Carrying out setup
The setup for a dispensing system can only be performed when
there are no load carriers in the wash cabinet.
To determine the precise throughput of the dispenser pump and the
pulse rate of the flow sensor, 2 measuring cylinders are required:
- 1x1000ml
- 1x100ml
 Put the dispensing system suction wand in a 500–1000ml measur-
ing cylinder.
 Fill the measuring cylinder with the process chemical to be dis-
pensed.
 Fill the 100ml measuring cylinder with the process chemical to be
dispensed.
Before dispensing system setup is performed, the dispensing sys-
tems need to be primed.
 Press the Fill dispensing systembutton.
 Press the button for the required dispensing system, e.g., DOS 1.
Once the process has finished:
 Press OK to confirm the message.
 Fill the 500–1000ml measuring cylinder with the process chemical
to be dispensed from the 100ml measuring cylinder and mark or
note the fill level.
 Completely fill the 100ml measuring cylinder with the process
chemical to be dispensed.
 Press the Set up dispensing systembutton.
 Press the button for the required dispensing system, e.g., DOS 1.
The following message appears in the display:
DOS setup for dispensing system... starting. Prepare dispensing system.
