6.6.4 Testing / determining the number of pulses of the flow sensors
per litre
To determine the number of pulses of each flow sensor, proceed as follows:
Connect a hose to the first flow sensor and insert the other end into a measuring
container.
Go to the o.-parameter level by entering code '10E5'.
Select the appropriate flow sensor [o.81 to o.85] with the arrow keys.
o.81 => Detergent alkaline
o.82 => Detergent acidic
o.83 => Disinfectant
o.84 => Cold water
o.85 => Warm water
Activate the selected parameter with the SET button
Reset the displayed number of pulses by pressing the 'Cool' key.
By pressing the 'cleaning' key, the corresponding dosing pump can now be acti-
vated or the water valve opened. Keep the 'cleaning' key pressed until the meas-
uring container is filled up to the 1-litre mark - and then release the key.
The display now shows the number of pulses per litre.
Record the number of pulses displayed and enter them in the corresponding L-
parameter [L121...L125].
Now repeat the procedure described above for each additional flow sensor.
TIP: If you do not have a 1-litre measuring container available, you can also use a
bucket with a defined filling quantity, for example. The number of pulses displayed
must be converted to pulses per litre.
