The recipe function can be used when the process
conditions vary so much that one calibration cannot
cover the entire range. Such process changes may be
caused by a conductivity or temperature change that
takes the signal level out of the normal operating range,
or by a consistency change that exceeds the measure-
ment dynamics (about 15%). In such cases the sensor
can be configured separately for each distinct process
situation. These setups can be saved as recipes (max. 7).
As the recipe function is needed only rarely, it is
password-protected. To edit the recipes go from M
AIN
MENU
=> S
ELFDIAGNOSTICS
=> S
PECIAL FUNCTIONS
and
then press the number key 0 (zero). When two or more
recipes have been calibrated, the recipe function is
automatically visible in the “Special functions” menu.
Select R
ECIPES
and press [ENTER] to open the
display shown in Fig. 9.11. Each of the calibrated
recipes reads “Ready”, and the currently used recipe is
also indicated by the text “In use”.
9.D.1. Selecting a recipe
Recipes are selected using either the Communicator or
the binary inputs. Set the selection mode with the
function key [F5&F6] K
EYBOARD
/ B
INARY INPUTS
, and
the set method will be shown under the heading R
ECIPE
SELECTION
. Recipes can be activated only with the
method set in this menu.
Selection mode: keyboard
When using this selection mode, first select the recipe
from the list with arrow keys and then press [F1&F2]
T
AKE INTO USE
.
Selection mode: binary inputs
When this selection mode is used, the MCAi will use
the recipe number set to binary inputs bin1...bin3
(where input bin1 is the least significant). For more
information see section 9.D.5.
9.D.2. Taking a new recipe into use
• Selection mode: keyboard
Select the desired recipe number (must be blank!) with
the arrow keys and press [F1&F2] T
AKE INTO USE
. The
MCAi will prompt: “The selected recipe is empty.
Start-up and calibrate the device for the recipe X?”
Press [F5&F6] Y
ES
to accept, and the MCAi will go to
the start-up mode for signal level setting. Starting with
signal level setting, perform start-up and calibration as
instructed in sections 6.A and 7.A of this manual. After
this the recipe is ready and will be taken into use.
• Selection mode: binary inputs
Select the desired recipe number (must be blank!) with
the binary inputs. The function T
AKE INTO USE
will then
appear in the Recipe menu. This function will not
appear if an already calibrated recipe is selected with the
inputs. Press T
AKE INTO USE
and the MCA
I
will prompt:
“The selected recipe is empty. Start-up and calibrate the
device for the recipe X?”. Press Y
ES
to accept, and the
MCAi will go to the start-up mode for signal level
setting. Starting with signal level setting, perform start-
up and calibration as instructed in sections 6.A and 7.A
of this manual. After this the recipe is ready and will be
taken into use.
As long as the start-up and calibration for the new
recipe have not been completed, the sensor will inter-
pret the situation as an error. This means that the current
output is set to the error mode defined for the previously
used recipe (0, 4, 20 mA or freeze). If the recipe is
changed before either the consistency calibration or
current output scaling has been performed for the new
recipe, the new recipe will disappear.
9.D.3. Erasing and overwriting recipes
If you wish to write a new recipe over an existing one,
you must first erase the old recipe. This can only be
done using the “Keyboard” selection mode. Select the
recipe with the arrow keys and press [F3&F4] E
RASE
R
ECIPE
. The MCAi will first ask you to confirm the
command; press Y
ES
and the recipe number will be free
to be used again.
NOTE: Recipe 1 and the recipe marked “In use” cannot
be erased!
