7 CONFIGURE SeedMaster 2 51

NOTES:
1. Selecting MANUAL SEED means that seeding is carried out on a regular basis using the “Manual
seed” selection in the Menu. However, even if any other type of seeding had been configured
previously, manual seeding can be performed at once any time as an exception by selecting
“Manual seed”. Password is needed.
2. If the seeding valve is operated directly by a PCS based on data received from SeedMaster 2, by
configuring AUTO SEED and selecting the same SET- POINT (supersaturation, or density) for
seeding as the one used in the PCS will result in approximately synchronous operation of the two
devices. This means that both will attempt to open the seeding valve at the same time, but only the PCS
will succeed, because in this case the DO2 digital output of the SeedMaster 2 should be left
unconnected. The advantage: there is no need for any outside information (digital input DIN2, or
information via digital data communication) on the completion of seeding performed by the PCS. Not
to forget: the set-points of seeding in the two devices must be identical!
3. In any case: SeedMaster 2 always needs information in time when seeding was carried out.
This may come from any one of the outside sources (Digital input, or COMMUNICATION), or it
can be self-generated (MANUAL or AUTOMATIC seeding).
7.6 ACTIVE INSTRUMENT
SeedMaster 2 can serve up to 2 vacuum pans or crystallizers. The device can be configured to serve only
one (I1, or I2), or 2 instruments (see: Ch. 7.1) simultaneously. Configuration is very simple (Fig. 7.12).
