Alarm display
If the pump detects one or more alarm conditions, LED 1
changes from green to red. When an alarm is active, the
LEDs indicate the type of alarm as shown in the following
table. If more than one alarm is active at the same time, the
LEDs only show the alarm condition with the highest priori-
ty. Alarm priority follows the order of the table.
When no alarm is active, the user interface automatically
displays pump performance.

Default setting
Button lock/unlock function
The button lock function serves to prevent improper use or
accidental changes to pump settings.
When the button lock is active, pressing the button has no
effect. This prevents users from accidentally accessing set-
ting mode while allowing them to use setting display mode.
To enable/disable the blocking function, press (1) key for
more than 10 seconds. In doing this, all the leds will flash,
except for the red one, to indicate the switching of the
blocking function.
Setting mode
To modify settings, press the button (1) for between 2 and
10 seconds. Users can only select new settings provided
the button lock function is disabled.
Available settings are displayed in a pre-defined sequence
that is repeated every time the button is briefly pressed and
released.
If the button is not pressed for over 10 seconds, the pump
exits setting mode and returns to performance display
mode.
