There is a PLC self checking function and the software can show the error codes. Refer to
the following table to perform troubleshooting.
ERR. CODE DESCRIPTION STEPS TO TAKE
E 01
A Program with a syntax error has
been written
Change to PROG. mode and correct
the error
E 02
Two or more OT (OUT) instructions
and KP(Keep) instructions are
programmed using the same relay.
Change to PROG. mode and correct
the program so that one relay is not
used for two or more OT instructions
and KP instructions. Or set the
duplicated output to “enable (K1)” in
system register20.
E 03
For instructions which must be used in
a pair such as jump (JP and LBL), one
instruction is either missing or in an
incorrect position.
Change to PROG. mode and enter the
two instructions which must be used in
a pair in the correct positions.
E 04
An instruction has been written which
does not agree with system register
settings. For example, the number
setting in a program does not agree
with the timer/counter range setting.
Change to PROG. mode, check the
system register settings, and change
so that the settings and the instruction
agree.
