Description of functions

6.4.1 Set up 1 – Sensor input
In this menu, you can change the measured value acquisition settings, such as the
operating mode, the measuring principle, or the electrode type.
Apart from the measured value attenuation, you have already made all the settings in
the menu at the first commissioning in Quick Setup (s. page 23). You can change the
selected values in this menu.
For the first entry to the parameter setting, you have to insert your specialist code
(s. page 20). To enter the menu, proceed as follows:
CODE CHOICE
(default = bold)
A1
One circuit CH1
One circuit CH2
Combined circuits
Independent circuits
Comb. circuits look-
ahead
Ind. circuits look-ahead
A2 CH1 – CH2
CH2 – CH1
CH1/CH2
CH2/CH1
(CH1 – CH2)/CH1
(CH2 – CH1)/CH1
(CH1 – CH2)/CH2
(CH2 – CH1)/CH2

INFO
Select measuring principle
(only for two-circuit device)
One circuit channel 1 / channel 2 = measurement via sensor
input 1 or 2
Combined circuits = measurement via both sensor inputs
with the option of creating a characteristic value (see next
field)
Independent circuits = independent measurement via both
sensor inputs
Combined / Independent circuits look-ahead = look-ahead
control with combined / independent circuits measurement
!
(only for instruments with 2 current outputs)
Note!
• If a two-circuit device is configured as such, it keeps these
settings even if a transmitter (circuit) is removed or is
defective.
• If, with a defective transmitter, the error message E006,
E007 is not required, then you can switch the device to
"one circuit". As each relay is assigned to a circuit (alarm,
rel. 1, rel. 2 to input 1; rel. 3, 4, 5 to input 2), you should
keep in mind that, in such a case, functions which access
the deactivated relay are no longer functionable.
Select characteristic value
(only related circuits)
Here, you can define a process-related characteristic value
as a further output parameter.
