The Run Time for SYS 4 since the last start is displayed.
History
The HISTORY key also allows the user to scroll through
the SAFETY SHUTDOWN buffers to display informa-
tion relating to the last 3 Safety Shutdowns which oc-
curred. Information contained in the SAFETY SHUT-
DOWN Buffers is very important when attempting to
troubleshoot a system problem. This data reflects sys-
tem conditions at the
instant
the fault occurred.
Information is stored in the SAFETY SHUTDOWN Buff-
ers on every 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 reset-
ting of a fault lock-out.
When the HISTORY key is passed, the following mes-
sage will appear.
The operator must then select which SAFETY SHUT-
DOWN Buffer is desired. When deciding this, keep in
mind that Buffer No. 1 is always the most recent fault.
As new fault information is stored, it is always placed in
Buffer No. 1, No. 1 is loaded to No. 2, No. 2 is loaded to
No. 3, and information previously in No. 3 is discarded.
To select a buffer, simply press the 1, 2, or 3 EN-
TRY key and press ENTER. Repetitively pressing the
ENTER key will allow the operator to scroll through the
information available in the SAFETY SHUTDOWN
Buffer.
In the information that follows, a sample message along
with an explanation is provided for all available mes-
sages.
This message informs the operator of the time and date
of the fault.
This message informs the operator of the nature of the
fault which occurred if it is on the MASTER Module.
