0110 Backup memory data error EEPROM
(Control PWB)
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Check that the EEPROM on the main
circuit PWB is peroperly installed on the
main circuit PWB and, if not, re-install it.
3. Replace the control PWB and check for
correct operation (see page 2-2-12).
0120 MAC address data error
For data in which the MAC
address is invalid.
EEPROM
(Control PWB)
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Check the MAC address on the network
status page.
3. If it is blank, obtain an EEPROM with its
MAC address written from the service
support and install.
4. Replace the control PWB and check for
correct operation (see page 2-2-12).
0130 Backup memory read/write
error (main NAMD)
Flash memory
(Control PWB)
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Replace the control PWB and check for
correct operation (see page 2-2-12).
0140 Backup memory data error
(main NAND)
Flash memory
(Control PWB)
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Replace the control PWB and check for
correct operation (see page 2-2-12).
0150 Backup memory read/write
error (control PWB)
No response is issued from
the device in reading/writing
for 5 ms or more and this
problem is repeated 5 times
successively.
Mismatch of reading data from
2 locations occurs 8 times
successively.
Mismatch between writing
data and reading data occurs
8 times successively.
EEPROM
(Control PWB)
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Check that the EEPROM is peroperly
installed on the control PWB and re-
install it.
3. Replace the control PWB and check for
correct operation (see page 2-2-12).
4. Check the EEPROM and if the data are
currupted, contact the service support.
0160 Backup memory data error
(control PWB)
Reading data from EEPROM
is abnormal.
EEPROM
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Execute U021 - memory initializing.(see
page 1-3-22)
3. If the EEPROM data are currupted,
contact the service support.
