4.4.1 Configuration
The configuration menu consents to set the general parameters of the instrument. Only those parameters
which are pertinent to the selection made and to the hardware installed will appear in the menu. When a
digital value is requested, pressing the ENTER key will cause a cursor to appear in the display: at this point a
numeric value may be entered using the second function of the keyboard pushbuttons. When ENTER key is
pressed again, the value shown on the display will be confirmed, whether the latter has been modified or not.
Here is a description of the parameters appearing in the menu. A summary of the configuration menu
flowchart follows in the next page.
4.4.1.1 Configuration
parameters
Language:
select the language of the displayed messages.
Available languages: Italian, English,
French, German, Spanish. Default: English
Password:
set the password, that is an alphanumerical code composed of up to 5 characters. Default
setting by Factory: 00000
Serial link:
optional serial communication link.
See Section 11.3 “Serial Communication” for detailed instructions
Cleaning:
logical sequence for periodical cleaning of the sensors.
See paragraph 4.4.1.3 for details
Temperature select:
select measuring units for displayed temperature value: °C or °F; default is °C.
Temperature set:
define temperature at which operate temperature compensation when the thermo-
resistance is faulty; default is 20 °C.
Altitude:
not
supported.
CCI in ‘OR’:
when AW400 is installed on a water analytical unit and another Micro2Chem is driving the
cleaning sequence for all the sensor installed on the water analytical unit, the AW400 that
is not driving the cleaning needs to be "informed" that its sensors are being cleaned: this
information comes through its CCI that are connected to the CCO driving the cleaning on
the other AW400. When CCI in OR option is chosen, if one or the other or both the CCI
is/are closed the AW400 "knows" that it has to freeze output signals.
Average:
for dual channels transmitters, with identical sensors installed; the transmitter computes
the average of the two input signals. The choice is Average NO or Average YES; default is
NO (the average is not computed).
Delta:
for dual channels transmitters, same installed parameter; the transmitter displays an alarm
when the difference between the two measured values is higher than the set value
allowed for the deviation. Default = 0.0 (the delta is not active).
Smoothing:
The number is the smoothing in seconds on the input signal. It can be separately set for
the three channels. Allowed values are 0.00 – 10.00. Default is 1.00
Digital I/O Setting:
allows to set the status of digital input and digital outputs.
Instrument test:
see paragraph 4.4.1.4
