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.
