5.7.2 Setting the 4...20 mA output inclusive error level
If you selected or left the 4...20 mA output in the previous step (for detailed information refer to
Selecting the output on page 36), the device automatically switches to this submenu. At first you
see the following display:
Your task is now to set the lower and the upper turbidity limits:
• Use the buttons ↑ and ↓ to define the lower turbidity limit which is assigned to the 4 mA output
level or leave the setting.
• Accept your selection by pressing ^.
i The device switches to the next menu item, i.e. the setting of the upper limit.
• Use the buttons ↑ and ↓ to define the upper turbidity limit which is assigned to the
20 mA output level or leave the setting.
• Accept your selection by pressing ^.
i The device switches to the last menu item of this submenu, i.e. "Error level".
In case of an error the 4...20 mA output can be used to indicate the problem. That means the
device can set the current either to 4.00 mA, 2.00 mA, 0 mA or to "OFF" ("OFF" is the default
setting and effects that the 4...20 mA output is unaffected by any error condition):
• Use the buttons ↑ or ↓ to choose the desired setting for the error level or leave the setting.
• Accept your selection by pressing ^.
i The device switches to the submenu "Configuring the alarm relays".
