10.4.3 Protection Function

10.4.3.1 Protective Functions

iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
The DC power supply PCB and the power supply PCB for each option in this equipment have protective functions against overcurrent and overvoltage which cuts
automatically the output voltage to prevent malfunction of the power supply circuit when a fault such as short circuit occurred on a load causes overcurrent or ab-
normal voltage.
When an abnormality occurs in 3VB (all-night power supply), all power supplies are cut.
When an abnormality occurs in other power supplies than the above, all power supplies but 3VB (all-night power supply) are cut.
If an abnormality occurs in 3VB (all-night power supply), turn off the main power switch of the printer assembly, eliminate causes for activation of the protective
circuit, and then replace the all-night power supply PCB (because the fuse of the all-night power supply PCB has burned out.)
For other cases than that, turn off the main power switch of the printer assembly, eliminate causes for activation of the protective circuit, leave it for approx. 3 min
or more, and then turn on the power again to reset the protective circuit.

10.4.4 Backup Battery

10.4.4.1 Backup Battery
iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
The main controller PCB for this equipment contains a lithium battery as a backup battery for various data in case that a blackout occurs or the power plug is dis-
connected.
The DC controller PCB does not contain a battery.
