It is advised to check data, including crystal content from time to time, or when, for example, feed syrup purity
has been changed considerably and change configuration parameters, if needed.
NOTES:
Use on-line data from a massecuite density, solids content or motor consumption transmitter
whenever available.
All parameters can be entered by manual entry (KEYBOARD) or via digital data communication.

LEVEL MEAS.
YES / NO Level measurement is optional. If the answer
was NO, then instead of LEVEL data CR.
SIZE (mean size) will be displayed on the
MAIN DISPLAY.
PAN MAX LEVEL 40 - 100 % If level is measured and available, max
level in %.
CONC. (REFR., SEED.) 65 - 95 % Concentration measured by the refracto-
meter when seeding.
CONC.(REFR., STRIKE END) 65 - 95 % Concentration measured by the refracto-
meter at the end of the strike.
TEMP. (REFR., SEED.) 30 - 85
˚C
Temperature measured by the refracto-
meter when seeding.
TEMP. (REFR., STRIKE END) 30 - 85
˚C
Temperature measured by the refracto-
meter at the end of strike, or cooling
crystallization.
CR. CONT. (STRIKE END) 0 – 60 % Crystal content at the end of the strike (% by
volume). It must be specified in Set up ->
Inputs, and can not be entered or modified
here.
SEED CRYSTAL SIZE 0.005 – 1.5 mm If shock, or full seeding with slurry is practiced
0.01 mm is typical.
PRODUCT CRYSTAL SIZE 0.03 - 6 mm Mean product crystal size.
LENGTH OF CRYST. TIME 30 - 420 min Length of the real time of crystallization (from
seeding to the end) in minutes. After the 1
st
strike the time of the last crystallization can
be accessed by going to DISPLAY -> TEST -
> OTHER DATA
AVERAGE SUPERSAT. 1< VALUE From seeding to the end of strike. After the
1
st
strike average supersaturation during the
last strike can be accessed by going to
DISPLAY-> TEST -> OTHER DATA, or use
the STRIKE HISTORY screen.
FEED SYRUP PURITY 55 - 100 % It must be specified in Set up -> Inputs,
and can not be entered or modified here.
