If the system finds any faults it records them
permanently in the alarms log (up to a maximum
of 15 alarms). For each recorded alarm a page
composed of 3 parts is displayed: an
alphanumeric code that identifies the type of fault,
a symbol that illustrates the fault in graphic mode,
and a message in the language selected on Page
10.0, giving a brief description of the fault.
By pressing the right button you can scroll through
all the pages of the log.
2 questions appear at the end of the log:
"Reset Alarms?"
Pressing OK (left button) resets any alarms still
present in the system.
"Delete Alarms Log?"
Pressing OK (left button) deletes the alarms
memorised in the log.
On page 12.0 you can set the system status in
ON, OFF or controlled by a remote signal EXT
(digital input IN1).
If ON is selected the pump is always on.
If OFF is selected the pump is always off.
If EXT is selected, reading of the status of digital
input IN1 is enabled. When input IN1 is energised
the system goes ON and the pump is started (on
the Home Page the messages "EXT" and "ON"
appear alternately at bottom right); when input IN1
is not energised the system goes OFF and the
pump goes off (on the Home Page the messages
"EXT" and "OFF" appear alternately at bottom
right).
For the connection of the inputs see par. 6.2.1
