Resume data lost
! Problem
Although the resume function had been set to ON, no resume data
has been retained since the BHT was not normally turned off and then
left without dry cells or battery cartridge loaded or with dead dry cells
or discharged battery cartridge loaded.
The BHT displays this error message for three seconds and
automatically runs the execution program from the point of
start-up.
Error in System Mode settings
! Problem
Your settings made in System Mode contain an error.
If this error occurs, the System Mode settings revert to the
factory defaults.
The BHT displays this error for three seconds and runs a user
program first registered in the BHT from the beginning. The
program may not be the auto-start execution program preset
before occurrence of the error.
If no user program is loaded in the BHT, the message "No
execution program loaded. Contact your administrator." appears
following this error message.
! Solution
Make your settings in System Mode again.
If the message "No execution program loaded. Contact your
administrator." appears, run System Mode and download a user
program(s) in DOWNLOADING menu.
(For the downloading procedure, refer to Chapter 2, Section 2.5.3,
[ 2 ]. For the starting up way of user programs, refer to Section 2.7.)
