6.1 Part Names
6.1.3 Universal model QCPU
No. Name Application
1) Base unit installation hole Pear-shaped hole for installing the unit on a panel such as a control panel. (For M4 screw)
2) Cover
Protective cover for extension cable connector. Remove this cover when connecting an
extension base unit.
3) Extension cable connector
Connector for transferring signals to or from the extension base unit. Connect an extension
cable.
4) POWER LED Power indicator LED for 5VDC. Turns on in green during normal output of 5VDC.
5) MODE LED
Indicates the mode of the CPU module.
On: Q mode
Flash:
Executional conditioned device test is being executed.
External input/output forced on/off function is being executed.
6) RUN LED
Indicates the operating status of the CPU module.
On: During operation with the RUN/STOP/RESET switch set to "RUN"
Off: During stop with the RUN/STOP/RESET switch set to "STOP"
When the error that stops operation is detected.
Flash:
When parameters or a program is written during STOP and the RUN/STOP/RESET
switch is moved from "STOP" to "RUN".
To turn on the RUN LED after writing the program, perform the following operations.
• Shift the RUN/STOP/RESET switch from "RUN" to "STOP" to "RUN".
• Perform reset with the RUN/STOP/RESET switch.
• Power on the programmable controller again.
To turn on the RUN LED after writing the parameters, perform the following operations.
• Perform reset with the RUN/STOP/RESET switch.
• Power on the programmable controller again.
(If the RUN/STOP/RESET switch is shifted from "RUN" to "STOP" to "RUN"
after changing the parameter values, the new values are not reflected on the parameters
related to the intelligent function module, such as the network parameters.)
7) ERR. LED
On: When the self-diagnostic error (other than a battery error) that will not stop operation is
detected.
(When continuation of operation at error detection is set in the parameter)
Off: Normal
Flash:
When the error that stops operation is detected.
When reset operation is performed with the RUN/STOP/RESET switch.
8) USER LED
On: Annunciator (F) turned on.
Off: Normal
9) BAT. LED
Flash (yellow): Battery error due to voltage drop of the CPU module battery.
On (green):
Keeps on for 5 seconds after competing of restoring the data that are backed up by the
latch data backup function to the standard ROM.
Flash (green):
When data are backed up to the standard ROM by the latch data backup function
Off: Normal
10) Serial number display Shows the serial number printed on the rating plate.
11) Module connector
Connector used for mounting an module or intelligent function module.
(To the connector of the spare space where no module is mounted, fit the accessory connector
cover or the blank cover module (QG60) to prevent dust from entering.)
12) DIN rail adopter mounting holes Holes for mounting a DIN rail adaptor.
13) FG terminal Ground terminal connected with the shield pattern of the printed circuit board.
14) LG terminal Power filter ground having a half potential of the input voltage.
15) Power input terminals Power input terminals for connection of a 100VAC to 200VAC power supply.
16) Battery Backup battery for use of the standard RAM and battery power time function.
