L2. PROTECTION LEVEL MODE
Menu>>Setup>>Password>>Protection Level Mode
Protection Level mode is the measurement used to monitor the flow through the pulse meters. There are three modes available:
•
Volume per
•
Timed
•
Crosscheck
The other settings available on this screen will change according to the mode selected.
L2.A VOLUME PER
Figure 19 - Protection Level - VOLUME MODE
Default setting is ‘Volume Per’
. In this mode the
system will allow a set amount (volume) of water
through the pulse meter during a defined period. e.g.
1500ltr water volume allowed in any half hour period.
In this setting there are three further options for
defining that period:
•
½ Hour
•
Hour
•
Day
By combining these values you increase or decrease
the ‘sensitivity’ of the systems measurement of flow
volume.
To edit the flow volume, press the edit button under the high or low volume value you wish to adjust to enter the value edit screen. Then
volume times).
In the example shown in Fig.19 above the system will allow 1500ltr per half hour during high volume periods, and 60ltr per half hour
during low volume periods. Any water use above this level will put the system into alarm.
L2.B TIMED
Timed
does not measure volume.
Instead it will
allow water flow for defined periods of time. Periods
available are:
•
10 minutes
•
15 minutes
•
30 minutes
•
60 minutes
Any
uninterrupted
flow above this user defined time
will put the AT-WFM into alarm. In the example in fig.20
the unit is set for 10 minutes. If the water flows for 11
minutes the system will go into alarm. If the water runs
for 9 minutes, stops, then flows for another 9 minutes,
stops, etc the system will not go into alarm.
Figure 20 - Protection Level - TIMED MODE
There are two reset options available:

– The Reset button must be pressed to stop the alarm and reset the controller
Automatic Reset
– The controller will automatically reset as soon as the water flow stops
Note:
A flow switch can be used in place of pulse water meters on this setting if required.
