Corrective action
Check the power supplied to the redundant
power supply modules mounted on the
redundant base unit.
The cause is a hardware failure of the
redundant power supply module. Please
consult your local Mitsubishi representative.
• Change the battery.
• Engage the battery connector when a
program memory, standard RAM, or the
back-up power function is used.
• Check the lead connector of the CPU
module for looseness. Firmly engage the
connector if it is loose.
Change the battery.
Change the CPU module.
Reset the CPU module and run it again. If the
same error code is displayed again, the
cause is a hardware failure of the CPU
module, I/O module, intelligent function
module, END cover, branch module, or
extension module. Please consult your local
Mitsubishi representative.
• Disconnect the extension block.
• Do not use the LA1S extension base unit.
• Reset the CPU module and run it again. If
the same error code is displayed again, the
cause is a hardware failure of the CPU
module, I/O module, intelligent function
module, END cover, branch module, or
extension module. Please consult your
local Mitsubishi representative.
