• 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. - Is the voltage and polarity of the power supply correct? (24 VDC) - Is not the load of the output signal short-circuited? - Is the load current of the output signal appropriate? - Is the voltage and polarity of the encoder power (ENC0_VDD/GND ENC1_VDD/GND) supply?
(5VDC) - Is not the mistake found in wiring? Grounding (FH-5050) • 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 internal circuits, the circuits may cause short-circuit with FG if the base is not used to mount the camera and result in malfunction or damage. • 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 Sensor Controller is connected to the FH-SC12/FH- SM12. 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 (FH-5050) • 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 power of the 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 apply stress to the connector by pulling or bending the cable. It may damage the connector. 14
