SAFETY PRECAUTIONS
Be sure to observe

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 machine 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 commis-
sioned maintenance technician, can release all of the safety cover interlocks. It is used for
such an extensive 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 inter-
lock is released, be sure to turn OFF the servo switch and restrict each shaft action before
work.
3. Handling of maintenance key
We basically do not deliver this maintenance key to you.
If you should make a request for the maintenance key, we will deliver it after exchanging the
certificates of delivery acknowledgement.
In that case, we assume no responsibility for any accidents caused by your unsafe acts, for
example, releasing the interlock function.
Your safety manager should manage the maintenance key adequately.

HEIGHT SENSOR UNIT
The CM88 is equipped with the height sensor unit which complies with Interna-
tional Standard IEC 825-1 (1993) as the class 1 light emitting diode unit and its
safety level is defined as “Lasers which are safe under reasonably foreseeable
conditions of operation.” However, if the LED unit disassembled or modified,
and used for the other purpose, the safety for the human being cannot be guar-
anteed. Therefore, great care must be taken when handling.
(1) Object of using the LED product
1
To detect the thickness of a chip picked up.
2
To detect a pick-up miss or tombstoning by detecting
1
.
3
To measure the heights of all nozzles and to control the heights by feeding back measuring
results.
(2) Measuring principle
To detect the nozzle height and the chip thickness by sensing the quantity of the light which comes
through the slit (5 mm × 0.1 mm) in front of the light receiving element.
