Battery Backup (Standard, Analog and Ethernet PLC Units)

All of the CLICK PLC units have a super capacitor to maintain back up data in SRAM.
However, the backup period by the super capacitor depends on the CLICK PLC unit type you
use.
If you need the CLICK PLC unit to maintain data in the SRAM for longer than the above
period after the power is shut off, you must install a battery in the CLICK PLC unit.
NOTE: CLICK Basic PLC units do not have the battery backup feature.
Use battery part number D2-BAT-1 (not included with the PLC unit; order battery separately).
Typical battery life is 3 years, which includes PLC runtime and normal shutdown periods.
NOTE: Please power off the PLC while installing and/or changing the battery.
To install or replace the D2-BAT-1 battery:
1.
Press the retaining clip on the battery door
and swing the battery door open.
2.
Install the battery into the coin-type slot
with the +, or flat, side out.
3.
Close the battery door so that it locks securely.
4.
Make a note of the date the battery was installed.
The battery backup is now available.
WARNING: Do not attempt to recharge the battery or dispose of it by fire. The battery may explode or
release hazardous materials.
TIP: The CLICK PLC has a feature that indicates the pre-scheduled battery replacement date has
passed. In the CLICK programming software, go to the pull-down menu: Setup > Battery backup Setup.
