Memory Function (see Fig. 26)
The software continually monitors incoming external signals. When the frequency of the impulses is high and the
pump is not able to dose all the corresponding strokes, the outstanding impulses can be recorded, up to a
maximum of 65,535, so as to dose these strokes as soon as possible (for example - there is a reduction in the
flow of water through the counter).
Memory
Function
OFF
(
Memory
icon off).
The pump does not record external impulses of (
▲
) keyboard strokes received. The under dosage situation is
however indicated, with a message that reads
ALL2
appearing on the display. This will disappear once the under
dosage situation has been resolved.
Memory
Function
ON
(
Memory
icon lit).
As soon as the pump starts recording outstanding external impulses or (
▲
) keyboard strokes, the
Memory
icon
flashes until all the recorded strokes have been completed.
If the memory is exceeded (more than 65,565.5355 strokes recorded) the Alarm LED also switches on and the
alarm repetition relay is activated.
WARNING:
The recorded impulses are deleted under the following conditions:
Switching the dosage pump off.
Entering programming.
Carrying out the priming procedure (pushing the
▲
and
▼
keys together).
Activating the level alarm with pump cut-out.
Activating the Flow Alarm.
The pump temperature exceeds the safety limit and the pump goes into self-
protect mode (when the temperature falls below the threshold the pump
restarts with the memory zeroed).
The set status is confirmed by pressing the
Prog
key and the programming moves on to selecting the Flow
function.
WARNING:
The pump may stop automatically due to a pump cut-out signal emitted by the level
sensor (
Level
icon and
Alarm
LED lit), see par. 3.1.4 “Checking the level of the liquid to be dosed”.

Flow Control Function (see Fig. 26)
This can be enabled by pushing the
▲
or
▼
keys, and stored in the memory by pushing the
Prog
key.
Displaying and Operation
On exiting programming the
N
value set during programming will be displayed.
The number displayed indicates the number of strokes the pump will dose for each external signal received. The
dosage frequency can be changed by pushing the
Mode
key and
▲
or
▼
keys together.
The
1:c
stays on and the
STOP
icon must be off while the pump is running.
The external impulses can be provided via a contact connected to PINS 11 and 12 or by pressing the
▲
key.
