Precautions for Safe Use
Power Supply and Wiring
• Keep the power supply wires as short as possible (Max.10 m).
• Use the cables and crimping terminals with the specified dimensions.
Do not directly connect an electric wire to the terminal lock that is simply twisted.
• Recommended wire size: 1.31 to 2.63 mm
• Terminal screw: M4
• Crimping Terminal
8.5 mm max.
Ground
• The power supply circuit of the Sensor Controller is not insulated from the internal circuit.
• When grounding the 24 VDC power supply's positive terminal, do not ground the controller's
FG terminal or the PLC's FG terminal. [ ,
nected inside the PC, current would run through the route shown in the figure below and
cause burnout.
• As in the case with a PC, you can safely ground the controller's FG terminal without a prob-
lem when there is no possibility that the SG (0 V) and the FG will short-circuit. For information
about the PLC wiring, check the specifications of your PLC before wiring.
• When the connected camera to the Sensor Control comes packaged with a base, make sure
to mount with the base. [ ] As the shell of the camera is the SG (0 V), it can cause short-cir-
cuiting between the SG (0 V) and the FG if a pedestal is not used.
• To avoid receiving an electric shock when grounding a positive terminal, do not touch the SG
(0 V) (camera, power supply terminal).
• Perform Class D grounding (with a grounding resistance of 100 Ω 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 connect it with a building beam, the controller might be adversely effected.

Precautions for Correct Use
The LCD panel used for the LCD-integrated type has been made using precision technology,
and sometimes a few pixels are missing in the panel. This is due to the structure of the LCD
panel, and is not a malfunction.
