Integrated Mold Sensing System MIS-304-P/T
Relay Box Mounting Instructions
For details of how to mount the overall system, see the Integrated Mold Sensing System MIS-202 Instruction Manual
(EN294-1906*).
Relay Box Mounting
The relay box can be mounted either by attaching using the magnets or by bolting using the mounting bolt holes.
When mounting using the magnets, attach to the moving part (platen) of the mold clamping unit. Also make sure the
operating temperature does not exceed 70 °C here.
If the magnets do not provide sufficient magnetic attraction or when attaching to a location where the operating
temperature exceeds 70 °C, the relay box should be bolted to the mold.
Handling Precautions
The relay box ambient temperature should be in the range 0 °C to 70 °C when mounted using the
magnets, and in the range 0 °C to 100 °C when mounted using the bolts.
When mounting using the magnets, check that there is sufficient magnetic attraction. If the
magnetic attraction is insufficient due to the mounting surface conditions, or if the relay box is to be
used for extended periods, mount using the bolts.
Keep credit cards and cash cards away from the magnets, as the magnetism may render them
unusable.
Likewise, the magnets may also cause malfunctions if precision equipment such as PCs and mobile
phones are close by.
Be sure to remove the magnets before mounting the relay box using the bolts. Otherwise, the box
will not make close contact with the mounting surface and will not be securely attached.
Be sure to use bolt mounting when mounting the relay box on a mold.
Mount using two M4 hex socket head bolts each on
either side. (M4 tapped holes must be drilled in the
mounting surface.)
Be sure to remove the magnets when using
bolts to attach the relay box. The magnets can
be removed by removing the screw in the center
of each magnet.
