"At Least One Die Protect Input Must be Used"
If the die protection system is not bypassed, then at least one of the sixteen inputs must be
programmed as some type other than "Unused". The operator must program at least one input to one
of the eleven active types.
"Memory Data Loss, Must Re-Program Input"
This message indicates that the programming information for this input has become corrupt and
cannot be used. The operator must first reprogram the input type either as Unused or as one of the
eleven active die protection types. When this is done, all other data values which are associated with
this type such as description, stop output, window setpoints, etc. will be displayed. These must also
be reprogrammed before continuing.
"Die Protection Board Fault XX"
This message will appear followed by a fault number (in the XX spaces above) if an internal fault
occurs on the module. The fault can be cleared by pressing the RESET ERROR softkey or by
cycling power to the unit.
Section 5.2 Diagnostic LEDs
The 5000-7 Die Protection Module has two LED indicators which provide status information for the
module. These are visible above the terminal strip on the connector card assembly and are labeled
as follows:
+5V
This green LED indicates the status of the internal +5 volt power supply for
the unit. It should normally be ON when power is on the unit and if off
indicates a fault in the System 5000 card rack.
RESET
This red LED turns on for approximately 1/2 second when power is applied
to the card rack. It should never turn on during normal running conditions
and if it does indicates a fault on the die protection module.
