[NO END COVER]
• There is no END cover.
• The LA1S extension base unit is used as an
extension base unit.
■Collateral information
• Common information: Module No. (Block No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
• Attach an END cover.
• Check that the modules are properly
connected with referring to the System
Monitor window.
• 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.

• Attach an END cover.
• Check that the modules are properly
connected with referring to the System
Monitor window.

• Reset the CPU module and run it again. If
the same error code is displayed again, the

[UNIT BAD CONNECT]
(1) The I/O module status is different from the
I/O module information at power ON.
(2) The I/O module (including the intelligent
function module) is nearly disconnected or
removed while the system is running.
(3) An extension cable is not securely
connected.
(4) Runaway or failure of the CPU module (built-
in I/O, built-in CC-Link)
• Malfunction due to noise or other causes
• Hardware failure
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: -
■Diagnostic timing
• Always
• Read common information of the error
using the programming tool to identify the
numeric value (module No.). Check the
module corresponding to the value and
replace it as necessary.
• Monitor SD1400 to SD1431 using the
programming tool to identify the module
whose data bit is "1". Check the
corresponding module and replace it as
necessary.
• Securely connect the connector part of an
extension cable to the module. (Insert the
connector until it clicks.)
• Take noise reduction measures.
• 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.

[EXT. CABLE ERR.]
An extension cable is disconnected.
■Collateral information
• Common information: Module No. (Block No.)
• Individual information: -
■Diagnostic timing
• When an END instruction executed
• Connect the extension cable.
• 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.
