e17 - e19
e20
e22 - e30
e31
On page 8.0 it is possible to choose the parameter to be displayed on the Home Page:
Measured head expressed in metres
Estimated flow rate express in m
Rotation speed expressed in revs per minute (rpm)
Voltage measured on the analogue input 0-10V
Power distributed expressed in kW
Operating hours
Liquid temperature measured on the input "A1V" (18-pole terminal block)
Liquid temperature measured on the input "A2V" (18-pole terminal block)
∆T Temperature difference of the liquid T-T1 in absolute value
On page 9.0 you can choose the language in which to display the messages.
On page 10.0 you can display the alarms log by pressing the right button.
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 9.0, 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?"
1.
Pressing OK (left button) resets any alarms still present in the system.
"Delete Alarms Log?"
2.
Pressing OK (left button) deletes the alarms memorised in the log.
On page 11.0 you can set the system status in ON, OFF or controlled by a remote signal EXT (digital
input I1).
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 I1 is enabled. When input I1 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 I1 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. 5.5.1
