5-8 Connect UPS
The OMRON S8BA UPS protects the AMR Controller from power failures, voltage variations and in-
stantaneous voltage drops. Short power interruptions will be backed up by the UPS and the AMR Con-
troller will continue normal operation. The UPS signals the AMR Controller when a power failure oc-
curs and then the AMR Controller can shutdown normally without data loss. The AMR Controller can
automatically start up again when the power is restored.
To connect the AMR Controller to the OMRON S8BA UPS use one of the following two options:
• The USB connector and Power Attendant Lite Utility Software.
Refer to 5-8-1 Connect UPS Using the USB Connector on page 5-41 for details.
This is the preferred connection method.
• The I/O connector and a custom software program
Refer to 5-8-2 Connect UPS Using the I/O Connector on page 5-43 for details.
WARNING
The use of an uninterruptible power supply (UPS) allows normal operation to continue
even if a momentary power failure occurs, possibly resulting in the reception of an er-
roneous signal from an external device affected by the momentary power failure. Take
external fail-safe measures. Where necessary, monitor the power supply voltage on
the system for external devices and use it as an interlock condition.
Precautions for Safe Use
• Always use an uninterruptible power supply (UPS) to prevent data loss and other system file
integrity issues caused by unexpected power interruption.
• Use an Omron S8BA UPS with the correct revision number to prevent improper system shut-
down.
• Correctly perform wiring and setting, and ensure that the shutdown by the UPS can be exe-
cuted.
Additional Information
• The minimum power requirements of the UPS are dependent on the power consumption.
Refer to 4-1-3 Power Consumption Specifications on page 4-4 for power consumption details.
• Refer to the OMRON website for S8BA specifications or to the UPS S8BA User's Manual
(Cat. No. U702) for the UPS manual.
Note that the power consumption details determine the output current/capacity of your UPS.
