Settings in the "Extended menu“
Relay outputs
In the menu item " prop. to “, you choose a
parameter to which the relay reacts. You can
choose between percent and volume ("prop.
to volume“ is useful when under "Conditioning
- Linearisation curves“, for example, a spheri-
cal tank or a user-programmable lin. curve is
selected). In the next menu item, you can
select the suitable
Unit . In the menu item
" Mode “, the mode of the relay can be se-
lected. The individual relay modes are de-
scribed on the following pages.
If mode "Rising tendency“ or "Falling ten-
dency“ is selected, the menu items "Devia-
tion“, "Dev. per time“, "Cycle time“ and
"Number of cycles“ appear.

With all other modes, the menu items "Low“
and "High“ appear. There you can determine
the switching points for the relay.
The menu item "
Failure mode “ always ap-
pears. "Failure mode off“ causes the relay to
deenergise when a failure (e.g. sensor
shortcircuit) occurs. "Failure mode hold“
causes the actual relay status to be main-
tained when a failure occurs.
Under "Add’l functions“ you can adjust a
switch on delay (t on) and a switch off delay
(t off) of the relay of max. 600 s (with the relay
modes "Rising tendency“ or "Falling ten-
dency“ no switching delay can be set).
