Detection of battery error and time for replacement
-
Special internal relays R9005 and R9006 will go on if the battery voltage drops. Create a program to
announce errors to the outside as necessary. Two seconds after starting supplying power, the battery
voltage is checked.
-
When the system register No.4 "Battery Error Alarm" is enabled, the ERR.LED of the control unit will
flash.
-
Although data will be retained for about a week after the detection of battery error without power, the
battery should be replaced as soon as possible.
Note:
-
If a week has passed without power after the special internal relays R9005 and R9006 turned on or the
ERR.LED flashed, retained memory data may be lost.
-
Regardless of how much time has passed after the detection of battery error, supply power to the
control unit for more than two minutes before replacing the battery.
-
Special internal relays R9005 and R9006 will be on when a battery error is detected regardless of the
setting of system register No.4.
