Turns on/off the 24V
Protective Functions
Protective Functions
The 24VDC circuits (used for driving solenoids, etc.) on the finisher controller PCB and saddle stitcher controller PCB are provided with a fuse or a motor driver with an overcurrent protective function.
The 24VDC input circuit of each controller PCB is also provided with a fuse which is blown when an excessive current flows.
Power supply unit is provided with an overcurrent/overvoltage protective function to shut off the output voltage automatically when an excessive current or voltage occurs due to a problem on the load
side (e.g., short-circuiting), thus protecting electric circuits.
Each circuit is provided with a fuse which is blown when an excessive current flows in the AC line, thus shutting off the excessive AC current.
