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 Systems 3 and 4. Pressing the Operating
Data key three times jumps directly to System 4.
At the end of this sequence the displays scroll back to
the beginning of the common data section.
4.4 OPERATING DATA – REMOTE PRINTOUT
The following text shows a typical example printout ob-
tained by pressing the Operating Data key with an op-
tional 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 ap-
propriate number of systems:

4.5 HISTORY KEY
If a safety shutdown occurs on the chiller, a comprehen-
sive list of operating and programmed settings data is
stored by the Microprocessor. The information is stored
at the instant of the fault, regardless of whether the fault
caused lockout to occur. This information is not affected
by power failures or manual resetting of a fault lockout.
The Microprocessor stores data for up to nine safety shut-
downs (up to nine on YCAS 2 system units). Once the
limit is reached, a further shutdown will cause the oldest
set of data to be discarded in favor of storing the new
shutdown data. The safety shutdowns are numbered from
1-9 with number 1 always being the most recent.
