(SD0)
The voltage(100 to 240VAC) of the
power supply module on the extension
base unit dropped to or below 85% of
the rated voltage.
(This can be detected from the control
system of the stand-alone system or
1520
redundant system.)
On the redundant base unit, the one
damaged redundant power supply
module was detected.
The 24 VDC power supplied to the
system management module AS92R
has dropped below 90% of the rated
1530 voltage.
(This can be detected from the control
system or standby system of the
redundant system.)
• The battery voltage in the CPU
module has dropped below stipulated
1600 level.
• The lead connector of the CPU
module battery is not connected.
Voltage of the battery on memory card 1
1601
has dropped below stipulated level.
Voltage of the battery on memory card 2
1602
has dropped below stipulated level.
The number of writing to flash ROM
(standard ROM and system securement
1610
area) exceeds 100,000 times.
(Number of writings >100,000 times)
*4 Function version is B or later.
*5 Function version is A.
*6 The module whose first 5 digits of serial No. is 04101 or later.
*7 The module whose first 5 digits of serial No. is 07032 or later.
*8 The module whose first 5 digits of serial No. is 08032 or later.
*9 The module whose first 5 digits of serial No. is 09012 or later.
*10 The Universal model QCPU except the Q02UCPU.
*11 The Q13UDHCPU and Q26UDHCPU
*12 This applies to the QnUDE(H)CPU.
*13 The module whose first 5 digits of serial No. is 10042 or later.
Corrective Action
Check the supply voltage of the power
supply module. If the voltage is
abnormal then replace the power supply
module.
Hardware fault of the redundant power
supply module. (Contact your local
Mitsubishi representative, explaining a
detailed description of the problem.)
Check the 24VDC power supplied to the
system management module AS92R.
• Change the battery.
• If the battery is for program memory,
standard RAM or for the back-up
power function, install a lead
connector.
Change the battery.
