Select menu 3.3.3 by pressing key <3> three times.
☺ This give you access to the options for the additive dispensing device.
Stroke
frequency
The Sening additive pump is a piston pump which regularly discharges
full strokes into the product flow. The frequency of the strokes is given
by the desired mixing ratio, product flow rate and the capacity of the
piston pump.
Press key <1>.
The parameter "Piston capacity" is called up.
The capacity of the Sening additive pump is approx. 50 ml.
Confirm the capacity value with <Enter>.
Define the meter factor of the additive pump with key <2>.
This factor is mandatory only when the additive dispensing is subject to
W & M inspection (see next parameter).
Meter factor The piston capacity is determined during the preliminary testing of the
pump and is included with the device. However, since the volume can
only be quoted as an integer, the meter factor is required for fine
adjustment.
The meter factor is calculated from the division of the volume V
Std
(parameter 3.3.3.1, "Piston capacity") by V
PC
(preliminary certificate).
The default (neutral value) is 1.0.
Confirm the value with <Enter>.
Press key <3>.
The injection point at which the additive is discharged into the product
flow is now defined:
Injection
point
selection:
0: No additive dispensing.
1: Additive dispensing before the measuring system.
2: Additive dispensing after the measuring system.
Define the hose volume with key <4>.
This volume states how much product is taken up by the measuring
system and the wet hose.
