Power Supply and Wiring
• Make sure to use the product within the power voltage specified by catalog, this manual, or instruc-
tion sheet.
• Never connect the product to AC power. If connected, it causes malfunction.
• Select and use the appropriate wire size based on consumption current.
• Keep the power supply wires as short as possible.
• Provide the power from a DC power supply (safety extra-low voltage circuits) that has been taken
measures not to generate high-voltage.
• Check the following again before turning on the power.
- Are the voltage and polarity of the power source set correctly? (24 VDC for positive terminal. 0
VDC for negative terminal.)
- Is the FG (functional grounding terminal) connected to the ground?
- Is the load of the output signal not short-circuited?
- Is the load current for the output signal within the specified range?
- Are there no wrong wirings?
- Are the voltage value and polarity of the power supply that is provided to the encoder cable (ENC0
VDD/GND, ENC1 VDD/GND) correct? (5 VDC)
• The recommended power supply for FH-L series is the S8VS-
£££
24 (manufactured by OMRON)
or S8VK-G-
£££
24 (manufactured by OMRON).
Grounding
• Since the power supply circuit for the Sensor Controller is described in the manual and instruction
sheet, please check it.
• When a base is packed in a camera that will be connected to the Sensor Controller, make sure to
mount the camera using the base. Since the enclosure of the camera body is connected to the inter-
nal circuits, mounting the camera without using the base allows the internal circuits to be directly
connected to the ground, which may cause malfunction or failure.
• Apply Class D grounding (grounding resistance: 100 [Ω] or less) Wire the grounding wire for the
Sensor Controller independently. If the grounding wire is shared with other devices or connected to
a building beam, the Sensor Controller may be adversely affected.
• Check the wiring again before turning on the power.
• Do not ground the plus (+) terminal when the FH series Sensor Controller is connected to the FH-
SC12/FH-SM12. The internal circuits may cause a short-circuit and result in malfunction.
• Do not ground the plus (+) terminal of the 24 VDC power source when the FH series Sensor Con-
troller is connected to the FH-MT12 with a USB cable. The internal circuits may cause a short-circuit
and result in malfunction.
• When using the Sensor Controller and the peripheral devices such as a monitor, USB connection
devices, RS-232C connection devices, there should be no potential difference in ground level. If not,
it may cause malfunction. Take measures that the potential difference does not occur between the
grounds for the Sensor Controller and the peripheral devices.
Others
• Use only the camera and cables designed specifically for the product. Use of other products may
result in malfunction or damage of the product.
