[<CHK>ERR ***-***]
Error detected by the CHK instruction. (The "***"
portion of the error message indicates the
numbers of contact and coil that have been
detected.)

Read the individual information of the error
using the programming tool to identify the
numeric value (error number). Check the
program corresponding to the value.
Use the DIP switches to set the valid
parameter drive to the standard ROM. Then,
switch power on again, and perform boot
operation from the standard ROM.
