Safety Precautions
Please be sure to read this manual before attempting to use the equipment.
1. Installation location
CAUTION
Install in a location where temperature and humidity conditions are within the ranges described
below.
Amplifier
Environmental temperature: －10° C to 50° C
Environmental humidity: 85 % RH or less (Non-condensing)
Relay box:MPC-308B
Environmental temperature: 0 °C to 70 °C (0 °C to 100 °C when not using magnets)
Environmental humidity: 85 % RH or less (Non-condensing)
Relay box: MRB-304-BI ,MRB-304-CV
Environmental temperature: 0 °C to 100 °C
Environmental humidity: 85 % RH or less (Non-condensing)
WARNING
To minimize the risk of unforeseen accidents, avoid installing equipment in the following locations.
(1)
Do not install in the following locations:
Hot locations or locations exposed to direct sunlight
Damp locations
Dusty locations
Environments containing corrosive gases or salt
Locations subject to sudden temperature or humidity fluctuations
Close to equipment that generates magnetic or electromagnetic radiation
Locations subject to the effects of radiation and radioactive materials
Locations such as laboratories where chemical changes may occur

(2) When installing the amplifier
The individual component dimensions are as shown below:
The amplifier is held in place by sticking the magnetic sheet on the bottom of the device to the surface
on which it is to be installed.
The following conditions must be complied with when installing the amplifier.
The surface on which it is installed must be flat and must be a strongly magnetic material (e.g., iron or
ferritic stainless steel) at least 5 mm thick.
The magnetic sheet must be fully in contact with the surface.
CAUTION
Take care, as there is a risk of injury if your fingers become trapped between the magnetic sheet and
the equipment or rig on which the device is mounted.
CAUTION
Keep credit cards and cash cards away from the magnetic sheet, as the magnetism may render them
unusable.
Likewise, the magnetic sheet may also cause malfunctions if precision equipment such as PCs and
mobile phones are close by.

(3) When installing MPC-308B relay box
(For more information on installing the MRB-304-BI or MRB-304-CV, see the separate instruction
manuals.)
MRB-304-BI instruction manual EN294-1959
MRB-304-CV instruction manual EN294-1960
The individual component dimensions are as shown below:
The relay box can be mounted using the magnets or bolt-mounted using the mounting holes.
When mounting using the magnets, attach to the moving part (platen) of the mold clamping unit. Make
sure operating temperatures do not exceed 70 °C here.
Mount with bolts if the magnets provide insufficient magnetic attraction; if ambient temperatures at the
installation location exceed 70 °C; or if the relay box is mounted to the mold.

CAUTION
Make sure ambient temperatures around the box are between 0 °C and 70 °C when mounting using
the magnets and between 0 °C and 100 °C when bolt-mounting.
CAUTION
When mounting using the magnets, check to confirm that magnetic attraction is adequate. If the
magnetic attraction is insufficient due to mounting surface conditions or if the relay box is to be
used for extended periods, mount using the bolts.
CAUTION
Keep credit cards and cash cards away from the magnets; the magnetic force may render them
unusable.
Likewise, the magnets may also cause malfunctions if precision equipment such as PCs and mobile
phones are located close by.
CAUTION
Remove the magnets before mounting the box with the bolts.
Otherwise, the box will not mount flush with the mounting surface.
M4 hex socket head bolts × 4
Magnet mounting screws × 2
Magnets × 2
Mount using the M4 hex socket head bolts in two of
the three holes on each side. (M4 tapped holes must
be drilled in the mounting surface.)
Remove the magnets before mounting using the bolts.
The magnets can be removed by removing the screws
in the center of the magnets.

2. Power supply
WARNING
Turn off power before connecting or disconnecting cables.
Leaving power on may result in electric shock or equipment damage.
WARNING
Before turning on power, confirm that the power supply specifications match the power supply
specifications for the equipment.
Contact with us if the specifications do not match. Using an unconfirmed power supply may result in
electric shock or equipment damage.
CAUTION
Always ground the equipment.
Failure to ground the equipment may result in electric shock or malfunctions.
3. Precautions
CAUTION
Always set the sensor or pressure transmitting pin using the software before first use or after
replacing them. Failure to set the equipment may result in incorrect measurements, equipment
malfunctions, and damage to peripheral equipment. Likewise, reset the equipment if it has been set
once but gives incorrect results.
CAUTION
Confirm that the wiring is correctly connected before attempting to use the equipment. Incorrect
wiring of the equipment may lead to incorrect measurements, equipment malfunctions, damage to
peripheral equipment, and serious accidents.
CAUTION
Altering the settings while carrying out measurements using the equipment will result in incorrect
measurements, equipment malfunctions, and damage to peripheral equipment.
CAUTION
Protect the equipment from impact or shock—for example, impact or shock caused by striking
against other objects.
Impact or shock may damage the equipment and lead to failures in the electrical circuits.
CAUTION
Do not remove the equipment case cover or attempt to disassemble the equipment.
Doing so may damage the case and affect durability and operations.
This system saves measurement data to a PC memory storage device (e.g., hard disk drive).
Periodically sort out stored data to prevent freezing or degradation of PC performance.
To prevent communication errors, always shut down the measurement software before turning off
the equipment power or disconnecting the USB cable connecting the equipment and PC.
VII
Do not open numerical data or alarm history csv files while acquiring data with the PC.
Opening such files while acquiring data with the PC will result in an error, and will turn the PC
interface off-line without updating the numerical data or alarm history.
Set the start trigger signal interrupt interval to at least 1 s.
Leave an interval of at least 1 s before starting measurement after changing the conditions or
aborting measurement using the [Stop] button.
Always make sure that the latest version of the measurement software is installed and used. Older
versions of the software will not operate with the latest version of the amplifier updated with
additional features.
The latest software version supports all previous amplifiers.
When upgrading the measurement software, always uninstall the old software version first before
installing the new version.
For details on how to attach the sensor to the mold, see Section 25 "Appendix".
