Output Current; Relay - Burkert 8225 Notice D'utilisation

4 OPERATION

4.3.5 Output Current

Within this mode, the measuring range of the conductivity measuring range is entered,
which corresponds to the output current 4-20 mA. E.g. 0 to 10 mS/cm corresponds to 4-
20 mA. The beginning of the measuring range might be larger than the end of it, e.g. 0 to 10
mS/cm corresponds to 20-4 mA (inverted output signal).
The adjustments (engineering unit and decimal point), which have been selected for the
conductivity display will be valid within this option.

4.3.6 Relay
Within this menu, the setting of the parameter limits can be defined. 2 limit values are ente-
red for each relay: 1- and 1+ or 2- and 2+. The user has also the option to invert the relays
and to set a delay time between 0 and 180 seconds. This delay shall prevent the relays from
being activated too quickly, e.g. when time for homogenization is required (e.g. measure-
ments in tanks with agitator). If the conductivity exceeds a limit value, the transmitter awaits
the set delay time before activating the relay in order to introduce a hysteresis effect. Units
and decimal points as selected in the submenu "UNIT" are actived within this menu.
The following condition must be observed 1- ≤ 1+, 2- ≤ 2+.
