Scenario Trigger Action
RAM Test During startup, press PB1.
Ethernet LEDs
in ACE 3660+
A detailed memory test of SDRAM
and SRAM plug-in is performed.
- At the beginning of the RAM test,
the four Ethernet LEDs (see left) will
blink three times. During the RAM
test, the LEDs will be lit.
If the RAM test succeeds, the four
LEDs will blink three times and turn
off and the restart sequence will
continue.
If the RAM test fails, the RTU will
freeze (restart sequence stops) and the
four LEDs will blink seven times.
The fail error code will be displayed
on the LEDs, in binary code, as
follows:
ERR Code 1
ERR Code 2
ERR Code 3
(where OFF LED = '0'; continuously
lit LED = '1'. The highest LED is the
most significant.)
-ERR Code 1 = Error in Flash
-ERR Code 2 = Error in SDRAM
-ERR Code 3 = Error in SRAM
- To exit/abort the RAM test in the
middle, restart the RTU (see RTU
Restart above.)
Erase User FLASH During startup, press both
PB1 and PB2 simultaneously
until the buzzer buzzes five
times quickly, then
continuously for three
seconds.
All the user FLASH memory content
excluding logging files (files tagged
as data logging files) is erased,
including the site configuration, user
application programs, user tables, etc.
