Example 4: Setting the Unit to Alarm on Hi-Floc Levels
High Floc Alarm
The unit is now able to pick up on high level of floc readings, to do this it reacts to the
raw echo trace rather than the processed echo. You are then able to set an alarm that
is only reacting to the raw floc levels which will activate if the % of intrusion (P163)
is reached between the distances set (in measurement units) in P160 Start distance
and P161 End Distance. So if the reading is low and sat near the bottom of the tank
the processed echo is low but the raw echo can be high.
The unit will pick up hi levels of floc near the surface which it can only do by looking
at the raw trace. The alarm On Delay P164 and Off Delay P165 can be set to prevent
passing ‘clouds’ of material in flight from nuisance alarming.
With the introduction of the High Floc Alarm feature, several different parameters and
features now need to be included into the manual. Below are the illustrations,
parameters and their descriptions which require adding to the new release of manuals
due to be compiled indicating how to program a high floc alarm.

Note: When setting a High Floc Alarm it is necessary to access two menu systems
the RELAYS menu to set up the relay and the FLOC ALARM menu to set the alarm
parameters.
