This advises that the common data has been completed
and that pressing the Enter key will now scroll through the
system history data for the master section of the chiller, i.e.
the data for System 1 followed by the data for System 2.
The data for each system is given by twenty informa-
tion displays as described under YCAS 2 System Mod-
els – System Data above.
After completing the system data for the master sec-
tion, pressing Enter again gives the following message:
Pressing the Enter key will now scroll through the sys-
tem data for System 3, then System 4, as for Systems
1 and 2 above.
At the end of this sequence, the display scrolls back to the
request to select a safety shutdown number to display.
4.7 FAULT HISTORY DATA – REMOTE PRINTOUT
The following text shows a typical example printout ob-
tained by pressing the History key with an optional
printer attached. In this case an example is given for a
YCAS 3 System Chiller. YCAS 2 System Models and
YDAS models provide similar printouts for the appro-
priate number of system:
