EC Directives

6-1 Applicable Directives
6-2 Concepts
6-3 Conformance to EC Directives
If the power remains off for a period exceeding the data backup period,
AR 1314 will turn ON to indicate that the capacitor can no longer back up data
and the data backed up by the capacitor will be cleared. AR 1314 will remain
ON unless it is turned OFF using I/O monitor operations, using memory clear
operations, or from the user program.
If desired, the PC Setup setting in DM 6604 can be set to create a fatal error
and thus stop the system when AR 1314 goes ON.
• The data stored in flash memory will not be lost even if power remains off for a
period exceeding the data backup period, because the data stored in flash
memory will be read to the CPU Unit when the CPM1A is turned on.
• If the power is turned off without changing the mode from PROGRAM mode to
RUN or MONITOR mode after having made changes in the data that is backed
up in flash memory, the changes will not be written to flash memory. If the pow-
er is then left off for more than 20 days (at 25_C), the changes (i.e., the con-
tents of the RAM) will be erased and the data values will become undefined.

EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to EMC
standards (see the following note). Whether the products conform to the stan-
dards in the system used by the customer, however, must be checked by the
customer.
EMC-related performance of the OMRON devices that comply with EC Direc-
tives will vary depending on the configuration, wiring, and other conditions of the
equipment or control panel on which the OMRON devices are installed. The cus-
tomer must, therefore, perform the final check to confirm that devices and the
overall machine conform to EMC standards.
Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility):
EMI (Electromagnetic Interference):
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC or 75 to
1,500 VDC meet the required safety standards for the PC (EN61131-2).
All CPM1A CPU Units with model numbers ending in "-V1" conform to EC direc-
tives.
The following restrictions apply to CPM1A CPU Units with model numbers not
ending in "-V1."
• Relay Output Units and Transistor Output Units of CPU Units with DC power
supplies conform to EC Directives. Relay Output Units, however, conform to
EC Directives only when the output load power supply is outside the ranges
specified for the Low Voltage Directive (less than 75 VDC or less than 50 VAC).
• Relay Output Units and Transistor Output Units of CPM1A CPU Units with AC
power supplies do not conform to EC Directives.
