About Safety Cover Interlock
1. Basic feature of safety cover interlock
Before starting regular automatic production on this machine, close all safety covers.
Since a screen displays the message prompting you to supply a member when it needs to be
supplied, open the corresponding cover according to the member to be supplied and then conduct
the work.
If you accidentally open a safety cover during automatic production, the machine comes to an
emergency stop to ensure the safety of operators.
2. How to use servo switch
Since an operator needs to put the hands or part of body into the machine for the purpose of model
changeover or maintenance, the operating panel is equipped with the servo switch in order to
ensure on-the-job safety. When this servo switch is turned OFF, all of the drive shafts of the ma-
chine will be inactive. For information about the operations above, refer to the instruction manuals
for each model.
About Key Switch for Maaintenance
1. Key switch for maintenance at our company
This switch, which is targeted for the technician belonging to our company or the commissioned
maintenance technician, can release all of the safety cover interlocks. It is used for such an exten-
sive maintenance work as you cannot perform.
2. Feature of key switch for maintenance at our company
It is dangerous to use this maintenance key, because the safety cover interlock function will be
disabled and both the hardware and software judge that the safety covers are closed; eventually,
the safety features will be disabled in all modes.
If you need to put your hands or part of body into the machine while the safety cover interlock is
released, be sure to turn OFF the servo switch and restrict each shaft action before work.
