When the ERR/ALM indicator flashes, connect the CX-Programmer to the
peripheral port and read the error message. If the message "BATT LOW"
appears on the Programming Console* and the Battery Error Flag (A40204) is
ON*, first check whether the battery is properly connected to the CPU Unit. If
the battery is properly connected, replace the battery as soon as possible.
BATT LOW
Once a low-battery error has been detected, it will take 5 days before the bat-
tery fails. Battery failure can be delayed by ensuring that the CPU Unit power
is not turned OFF until the battery has been replaced.
Note *The PLC Setup must be set to detect a low-battery error (Detect Low Bat-
tery). If this setting has not been made, the BATT LOW error message will not
appear on the Programming Console and the Battery Error Flag (A40204) will
not go ON when the battery fails.
Install a replacement battery within 2 years of the production date shown on
