removal" menu item (menu 8) can be used for removal of residue from
the measuring system. It is controlled in accordance with the maximum
operating time (parameter 3.1.8.5.2), with the <START> and <STOP>
keys.
If the EPE2 detects that a product change cycle has not been completed
after a product change, the driver also has the option in these residue
removal modes to call up the menu point “Automatic residue removal”
directly from the residue removal request before actual discharge.
Pressing the <F1> key in the residue removal request will call up the
menu point “Automatic residue removal”, via which the output from EPE2
can be controlled.
If you choose "EPE2 AI" in the menu "Residue removal via EPE2" (menu
8), the state of the EPE2 sensor is also being monitored during residue
removal.
If a complete residue removal cycle has been detected, the EPE2 outputs
are deactivated and the residue removal will be paused.

The options for control and operating sequences when using EPE2-
AIII (4) and EPE2-AI (5) are mostly identical. If parameter 3.1.8.5.1 is set
to 5 (EPE2-AI), the user is instructed, after completing the residue
removal and fill procedure, also to observe the prescribed “minimum
discharge quantities after residue removal”. The acknowledgment of this
instruction is recorded in the events log book. If an EPE2-AI is used, it is
also possible to remove residues during product change between AI- and
AIII-products.
