YORK INTERNATIONAL 57
FIG. 21 HISTORY PRINTOUT
NOTE: In actual print-outs, this would be one continuous print-out.
Shutdowns which occurred. The information is stored at
the instant of the fault regardless of whether the fault
caused a lockout to occur. The information is also not
affected by power failures (long term internal memory
battery back-up is built into the circuit board) or manual
resetting of a fault lock-out.
When the HISTORY key is pressed, a Printout is trans-
mitted of all system Operating conditions which were
stored at the instant the fault occurred for each of the 3
SAFETY SHUTDOWN BUFFERS. There is one buffer
(storage area) for data related to each of the last 3 safety
shutdowns.
The printout will begin with the most recent fault which
occurred. The most recent fault will always be stored as
SAFETY SHUTDOWN NO. 1 (See printout Fig. 21). Iden-
tically formatted fault information will then be printed for
SAFETY SHUTDOWN NO. 2 and SAFETY SHUTDOWN
NO. 3.
Information contained in the SAFETY SHUTDOWN Buff-
ers is very important when attempting to troubleshoot a
system problem. This data reflects the system condi-
tions at the instant the fault occurred and often reveals
other system conditions which actually caused the safety
threshold to be exceeded. (See Fig. 21)
