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 ventilation holes and fan outlet regularly to 

prevent dust and particles from clogging them. If they are 

blocked, heat is trapped inside, causing a malfunction.

• 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.

• When mounting the Sensor Controller using the DIN rail 

mounting bracket, make sure the screw is tightened.

• Make sure to mount the product on DIN-rail securely.

Power Supply and Wiring

• Make sure to use the product with the power supply 

voltage specified.

Do not connect AC power source to Sensor Controller. If

failure.

• The recommended power supply is the S8VS-

○○○

24 

(manufactured by OMRON) or S8VK-G-

○○○

24 

(manufactured by OMRON).

• Use the wire of a suitable size (AWG 16 to 12) according 

to the current consumption.

• 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 source set 

correctly? (DC24V for positive terminal. DC0V for 

negative terminal.)

 - Make sure to connect the earth (FG) only to the 

grounding terminal.

 - 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?

●Ground

• The power supply circuit of the FH-L series Sensor 

Controller is not insulated from the internal circuit.

• When the connected camera to FH-L series Sensor 

Control comes packaged with a base, make sure to 

mount with the base. 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 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-L series Sensor Controller independently. 

If sharing the ground line with other devices or connecting 

it with a building beam, the Sensor Controller might be 

adversely effected.

• Check wiring again before turning on the FH-L series 

Sensor Controller.

Do not ground the plus (+) terminal of the 24VDC power 

source when the FH-L series Sensor Controller is 

connected to the FH-MT12 with a USB cable.Doing so 

may cause a short circuit of the internal circuit, resulting 

in a malfunction.

Do not ground the plus (+) terminal when the FH-L series 

Sensor Controller is connected to the 

FH-SC12/FH-SM12.Doing so may cause a short circuit of 

the internal circuit, resulting in a malfunction.

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.

Please insert monitor connector perpendicularly so that 

the connector resin part and pin are not rubbing against 

each other. Damaged pin may cause contact failure due 

to generation and invasion of resin powder.

• Always turn OFF the power of the FH-L series Sensor 

Controller and peripheral devices 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

  (Bend resistant camera cable) 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.

• While the power is ON or immediately after the power is 

turned OFF, the FH-L series Sensor Controller and 

camera case are still hot. Do not touch the case.

• When disposing of the product, treat it as an industrial 

waste.

• Do not drop the product nor apply excessive vibration or 

shock to the product. Doing so may cause malfunction or 

burning.

• This product is heavy. Be careful not to drop it while 

handling. 

• A lithium battery is incorporated, so a severe injury may 

rarely occur due to ignition or explosion.

Be sure to take fail-safe measures externally when 

controlling stages and robots by using the measurement 

results of the Sensor Controller (axis movement output by 

calibration and alignment measurement).

Image Processing System

Ambient Temperature

• For good ventilation, provide a clearance of 50 mm or 

more above the sensor controller away from other 

devices in the normal floor mounting. For the right and left 

sides, provide a clearance of 30 mm or more, and for the 

back side, 15 mm or more. These clearances are also 

required when mounting multiple sensor controllers side 

by side. For the back mounting, the back-side clearance 

of 15 mm is nor required.

• Do not install the product immediately above significant 

heat sources, such as heaters, transformers, or 

large-capacity resistors.

• Do not let the ambient temperature exceed 55

(127°F).

• Provide a forced-air fan cooling or air conditioning if the 

ambient temperature is near 55

(127°F) so that the

ambient temperature never exceeds 55

(127°F).

Noise Resistance

• Do not install the product in a cabinet containing 

high-voltage equipment.

• Do not install the Sensor Controller within 200 mm of 

power cables.

Component Installation and Handling

• Touching Signal Lines

When touching a terminal part or a signal wire in a 

connector, take anti-static measures using a wrist strap or 

another device to prevent damage from static electricity.

• Handling a USB Memory Device/SD Memory Card

Before removing a USB memory device or SD memory 

card, make sure that data is not being read or written to 

them.

• For a USB memory device, the memory device's LED 

flashes while data is being read or written. Make sure that 

the LED stops flashing before removing the memory 

device. 

• Do not insert an SD card in the reverse orientation, at an 

angle, or in a twisting manner.

• For an SD memory card, the SD BUSY LED of Sensor 

Controller flashes while data is being read or written. 

Make sure that the LED stops flashing before removing 

the card.

• Turning OFF the Power

When a message is displayed indicating that a task is in 

progress, do not turn OFF the power. Doing so causes 

the data in the memory to be corrupted, resulting in the 

product not operating properly upon the next start-up. 

Do not turn OFF during saving data to Sensor 

Controller.

Possible to be corrupted data and Sensor Controller may 

not perform correctly at next startup.

When turns OFF, conform the followings proceedings 

have completed. and then operate again.

-

When saves using Sensor Controller:

Confirm the save processing is completed and next 

operation is possible.

-

When saves using communication command:

Intended command is completed.

BUSY signal is turned OFF.

Setting of Power Source

The power source need to be supplied from DC power 

source apparatus which is taken a save ultra-low voltage 

circuit: to protect high voltage.

Maintenance

• Turn OFF the power and ensure the safety before 

maintenance.

• Clean the lens with a lens-cleaning cloth or air brush.

• Lightly wipe off dirt with a soft cloth.

• Dirt on the image element must be removed using an air 

brush.

• Do not use thinners or benzene.

Communication with High-order Device

After confirming that this product is started up, 

communicate with the high-order device. During start-up, 

an indefinite signal may be output from the high-order 

interface. To avoid this problem, clear the receiving 

buffer of your device at initial operations.

Fail-Safe Measures

• When controlling stages and robots using the 

measurement results from the FH-L series Sensor 

Controller (axis movement output based on calibration 

and alignment measurement),  always take fail-safe 

measures within the stage and robot systems, such as 

checking whether the data obtained from the 

measurement results is within the range of movement of 

the stages and robots. 

• On the FH-L series Sensor Controller side, 

use logical operations and conditional branches in a 

complementary way to add a check process based on 

the range of movement of the stages and robots, for 

example, "data is not externally output if in a range of 

-XXXXX to XXXXX."

Connecting the Sensor Controller and Monitor with a 

Switcher and Splitter

Do not use devices that make the sensor controller 

recognize the monitor again when switching operation 

is performed. Re-recognition process in switching 

operation has an effect such as a delay in 

measurement time.
