YORK INTERNATIONAL
Safety 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. 20).
Identically formatted fault information will then be printed
for SAFETY SHUTDOWN NO. 2 and SAFETY SHUT-
DOWN NO. 3.
Information contained in the SAFETY SHUTDOWN
Buffers is very important when attempting to trouble-
shoot a system problem. This data reflects the system
conditions at the instant the fault occurred and often
reveals other systems conditions which actually caused
the safety threshold to be exceeded. (See Fig. 20)
