9.3.3 Display settings
In the Display settings menu the appearance of the parameter on
the parameter screen and in the stored parameter files can be
configured.
To change the name of the parameter, select Name with [Up]- and
[Down] buttons and by pressing [OK] button the name can be
changed with [Up]-, [Down]-, [Left]- and [Right] buttons. Pressing
[OK] button confirms the new name.
To change the unit of the parameter, select Unit with [Up]- and
[Down] buttons and by pressing [OK] button the unit can be
changed with [Up]-, [Down]-, [Left]- and [Right] buttons. Pressing
[OK] button confirms the new unit.
Disp. Format shows the number of decimal places actually
displayed.
To change the number of decimal places, select Disp. Format
with [Up]- and [Down] buttons and by pressing [OK] button the
number of decimal places can be changed with [Up]- and [Down]
buttons. Pressing [OK] button confirms the new number of
decimal places.
Load Defaults: Reloads the defaults from the sensor.
To reload the default display settings from the sensor select Load
Defaults with [Up]- and [Down] buttons and by pressing [OK]
button the default display settings are loaded from the sensor.
All modifications performed by the operator within the Display
settings will be documented in the logbook of the CU 382.
9.3.4 Alarm settings
In the Alarm settings menu a lower and upper limit for an alarm
can be defined. An exceeding of these limits will generate an
alarm and may stop the controller depending on the controller
settings (see table below and section
9.4 Controllers / settings
).
To change the requirement for acknowledge an alarm, select
Require ack. with [Up]- and [Down] buttons and by pressing [OK]
button Yes and No can be toggled with [Up]- and [Down] buttons.
Pressing [OK] button confirms the new requirement.
To change the lower level of alarm-trigger, select Al. lower with
[Up]- and [Down] buttons and by pressing [OK] button the lower
level can be changed with [Up]-, [Down]-, [Left]- and [Right]
buttons. Pressing [OK] button confirms the new lower level.
To change the upper level of alarm-trigger, select Al. upper with
[Up]- and [Down] buttons and by pressing [OK] button the upper
level can be changed with [Up]-, [Down]-, [Left]- and [Right]
buttons. Pressing [OK] button confirms the new upper level.
9.3.5 Output
To allocate the parameter to an output, select Output with [Up]-
and [Down] buttons and by pressing [OK] button the output can
be changed with [Up]- and [Down] buttons. Pressing [OK] button
confirms the output.
Following a list of possible outputs:
– Analog output (4/20 mA #1,2,3)
– Digital output (Level, PULS, PWM)
For configuration of the analog and digital outputs see section
9.3.6 Output settings
.
9.3.6 Output settings
In the Output settings menu a parameter can be allocated to an
analog or digital output.
If an analog output is chosen, [4 mA] defines the parameter value
for 4 mA and [20mA] defines the parameter value for 20 mA.
Parameter values between these two limits will be calculated
according to a linear calibration.
To change the parameter value that will be mapped to 4 mA
select [4 mA] with [Up]- and [Down] buttons and by pressing [OK]
button the parameter value can be changed with [Up]-, [Down]-,
[Left]- and [Right] button. Pressing [OK] button will confirm the
parameter value.
To change the parameter value that will be mapped to 20 mA
select [20 mA] with [Up]- and [Down] buttons and by pressing
[OK] button the parameter value can be changed with [Up]-,
[Down]-, [Left]- and [Right] button. Pressing [OK] button will
confirm the parameter value.
If a digital output is chosen, three different kinds of types (Level,
PULSE, PWM) can be defined. The individual output types are
explained below:
To change the digital output to type Level select Type with [Up]-
and [Down] buttons and by pressing [OK] button the type can be
changed with [Up]-, [Down] button to Level. Pressing [OK] button
will confirm the type of digital output.
After confirming an additional row will be available.
To change the threshold level of the level output select Threshold
with [Up]- and [Down] buttons and by pressing [OK] button the
threshold level can be changed with [Up]-, [Down]-, [Left]- and
[Right] button. Pressing [OK] button will confirm the threshold
level.
Value:
Within this line the measured value of the sensor
as displayed on the Parameter screen also (using
the actual calibration).
Private:
In case of a pH::lyser or redo::lyser connected, this
value is the quality factor of the sensor. 0 means
bad quality and 1 means perfect quality of
measurement. In case of any other sensor
connected, this value is the raw value of the
sensor currently measured.
S-Status:
Sensor status (see sensor documentation for
further details). 0000 means status is ok.
P-Status:
Parameter status (see sensor documentation for
further details). 0000 means status is ok.
