Precautions for Safe Use
● Installation Environment
• Do not use the product in areas where flammable or explosive gases are present.
• Install the product so that air can flow freely through its cooling vents.
• Clean the vent hole and discharge opening to prevent dust or particles from blocking them. Blocked
cooling vents or discharge opening of the fan increasing heat inside, causing malfunction of the product.
• Do not install the product close to high-voltage devices and power devices in order to secure the safety of
operation and maintenance.
• Make sure to tighten all installation screws securely.
● Power Supply and Wiring
• Make sure to use the product with the power supply voltage specified by this manual.
• Use the specified wire size (AWG10 to 16).
• Keep the power supply wires as short as possible (Max.2m).
• Use a DC power supply with safety measures against high-voltage spikes(safety extra low-voltage circuits
on the secondary side).
• Do the following confirmations again before turning on the power supply.
− Is the voltage and polarity of the power supply correct? (24VDC)
− Is not the load of the output signal short-circuited?
− Is the load current of the output signal appropriate?
− Is not the mistake found in wiring?
− Is the voltage and polarity of the encoder power (ENC0 VDD / ENC0 GND / ENC1 VDD / ENC1 GND)
supply? (5VDC)
● Ground
• The power supply circuit of the FH sensor controller is insulated from the internal circuit.
• Be sure to use a base to install the camera connected with the FH Sensor Controller. Since the exclosure
of the camera main body made of metals is short-circuited with the internal circuit, the internal circuit might
be short-circuited with FG if no base is used, so that failures or malfunctions may be caused.
• Perform Class D-class grounding (with a grounding resistance of 100Ω or less).
• Keep the ground line as short as possible by setting the grounding point as close as possible.
• Ground the FH Sensor Controller independently. If sharing the ground line with other devices or
connecting it with a building beam, the controller might be adversely effected.
• Check wiring again before turning on the Controller.
● Other
• Use only the camera and cables designed specifically for the product. Use of other products may result in
malfunction or damage of the product.
• Always turn OFF the Controller's power before connecting or disconnecting a camera or cable. Connecting
the cable with power supplied may result in damage of the camera or peripheral devices.
• For the cable that is flexed repeatedly, use the robotic cable type (flexing resistance type) to prevent
damages.
• Do not apply torsion stress to the cable. It may damage the cable.
• Secure the minimum bending radius of the cable. Otherwise the cable may be damaged.
• Do not attempt to dismantle, repair, or modify the product.
• Should you notice any abnormalities, immediately stop use, turn OFF the power supply, and contact your
OMRON representative.
• The FH Sensor Controller and camera case are hot while power is supplied or directly after the controller is
turned off. Do not touch the case.
• Be sure to dispose of the product as industrial waste.
