(4) Precautions for clock setting

(a) Clock setting
1) Setting method
Set the clock of the C Controller module as described in Page 4-30, Section
4.7 (4) (a).
If the year 2100 is exceeded after clock setting, clock data of the year 2100
and later can be used until the C Controller module is restarted.
At the time of restart, year data of the C Controller module will be reset to those
of 2000 to 2099.
2) Condition for the setting
The clock of the C Controller module must be set with the QBF_WaitEvent and
QBF_WaitUnitEvent functions not being executed.

(5) Precautions for starting the C Controller module

(a) Time required for connection from each utility to the C Controller module
After power-on or reset, the C Controller module is ready to connect to each utility
at the following timing.
• When executing the script file, "STARTUP.CMD":
Upon completion of the RUN LED flashing
• When not executing the script file, "STARTUP.CMD":
Fifteen (15) seconds after completion of the start or reset process
Do not attempt a connection before the above timing after power-on or reset.
Changing "Priority" to a larger value in the Option tab of C Controller setting utility
increases the time after which the C Controller module can be connected.
(b) Flashing "01" or "02" of the 7-segment LED (Q12DCCPU-V only)
At start-up of the C Controller module, "01" or "02" flashes on the 7-segment LED
in the following cases.
• When the C Controller module is in factory-default state
(Because the standard RAM is not initialized)
• When the C Controller module is left unused for a long period of time with no
battery installed
(Because the standard and battery-backed-up RAM data are corrupted)
If "01" or "02" flashes on the 7-segment LED, install a battery and perform the
module initialization setting procedure. ( Page 6-77, Section 6.10.1 (6))
