Function
Functions are going to be assigned to the relay which has been chosen by en-
tering the >Channel Number<.
Available are:
-
inactive
-
(relay will energise if a flow limit value [to be set] has been exceeded and
will de-energise if flow falls below a second limit value [to be set])
-
Velocity output (relay will energise if a velocity limit value [to be set] has
been exceeded and will de-energise if velocity falls below a second limit
value [to be set].)
The functions below can be set only once:
-
Total positive impulses (relay will output volume-proportional impulses if
the flow direction is positive. Weighting and impulse duration are free
programmable)
-
Total negative impulses (relay will output volume-proportional impulses if
the flow direction is negative [= backwater]. Weighting and impulse dura-
tion are free programmable)
-
Error messages (relay will energise in case of error messages such as
sensor error, cable break, power failure, processor failure or similar))

Defining the relay function
Logic
Pressing the >ALT< key enables to select between >normally open< and >nor-
mally closed<. The relay is going to energise if >normally open< has been se-
lected and the according value has been reached, if >normally close< has been
selected the relay will energise immediately after the parameter has been set
and will de-energise as soon as the according value has been reached.
Trigger Levels
This menu will be indicated only if the function >Limit contact< has been cho-
sen.
