Alarms Function and Display
The alarm display can be accessed by selecting ‘Alarming’ in the Menu
(press the Menu button and use the up and down buttons to select).
Pressing the Menu button again will close the totalizer display.
The alarm screen looks as follows (example for High flow alarm 95%, Low
flow alarm 5% and setpoint deviation alarm 2%):
The alarm function has three different alarm modes per channel: absolute
maximum, absolute minimum and deviation alarm versus setpoint.
Adjusting one of these alarms is done in three steps. Step 1: select the line
of the alarm by using the up and down buttons. Step 2: press ‘Enter’ and
select alarm ‘ON’ or ‘OFF’ by using the up and down buttons, confirm the
by pressing ‘Enter’ again. Step 3: adjust the alarm value, if necessary, and
press ‘Enter’ to confirm this setting and to go back in the Menu itself.
If two channels are displaying an alarm the flashing message of these
channels goes synchronically.
Start-Up Preference
The setpoint values after power up are determined in the menu “Start-up
prefs”.
This can be done per channel independantly. It is possible to start with the
memorized setpoint values ( the setpoint that was used before power
down) or always power up with a zero setpoint.
Default factory settings are “preset to zero after power up”.
