31 Appx.1: Setting the System Lock

31.3 Display of Time Limit Warning and Alarm Notification

(1) If the number of days remaining before expiration reaches 7 or less, the warning "Z64 Valid term soon to be
expired" appears at the bottom right of the screen.
This warning appears at every cycle start after power ON until the expiry date comes. Cycle start operation is
enabled before the expiry date.
(2) If the expiry date is passed, the alarm message "Z65 Valid term has been expired" appears, which disables cycle
start operation. Reset signal is unable to cancel this alarm. Instead, enter the decryption code issued by a machine
tool builder, and then turn OFF and ON the CNC power.
If the expiry date is over during a cycle start operation, the operation continues until automatic operation pause,
block stop or reset is input.
If the expiry date is over during a cycle start operation and automatic operation or block stop occurred, cycle start
operation cannot be performed.

31.4 Caution

(1) The system lock function is enabled by setting an encryption key and an expiration date while the system lock is
disabled. Be careful that the date and time of the CNC cannot be set both to a past and to a future from the
expiration date while the system lock is enabled.
(2) MTBs need to manage the encryption dedicated tool and the encryption key not to be leaked to the users. The
encryption key file must be created on a PC.
(3) If you turn OFF and ON the power after the time limit has expired, "EMG Emergency stop LINE" may appear at the
same time.
(4) When the clock data is incorrect without a battery backup, the automatic start cannot be performed. Exchange the
battery and set the current date and time.
(5) If you upgrade the M800 Series/M80 Series software version from C3 or older to C4, perform the upgrading work
after canceling system lock.
(6) When you upgrade the M800 Series/M80 Series software version from C3 or older to C5 or later with system lock
enabled, the password for the system lock is automatically expanded to 8 digits. To issue a decryption code, add
"0000" to the head of the conventional encryption key. Moreover, use the "System Lock Pass Code Maker" (BND-
2201W000-A0 or later) to issue the decryption code.
(7) When you downgrade the M800 Series/M80 Series software version from C4 or later to C3 or older, you cannot
perform the downgrade work with system lock enabled. To downgrade from version C4 or later to version C3 or
older, cancel system lock and then perform the downgrade work.
