4.5.3 Reset operation
For the Universal model QCPU, the RUN/STOP/RESET switch of the CPU module is used to
switch between the RUN status and STOP status and to perform RESET operation. Moving the
RUN/STOP/RESET switch to the reset position will not reset it immediately.
Perform reset operation with the RUN/STOP/RESET switch as shown in following figure:
NOTES Hold the RUN/STOP/RESET switch in the RESET position until reset processing is complete
(the flashing ERR. LED turns off).
If you release your hand from the RUN/STOP/RESET switch during reset processing (the
ERR. LED is flashing), the switch will return to the STOP position and reset processing can-
not be completed.
Operate the RUN/STOP/RESET switch with your fingertips. To prevent the switch from being
damaged, do not use any tool such as screw driver.
