Precautions for Safe Use
Power Supply and Wiring
• Make sure to use the product with the power supply voltage specified by catalogue, this manual, or
Instruction sheet.
• Do not connect AC power supply.
If AC power source is connected, possible to cause of failure.
• Use the appropriate wire size.
• Keep the power supply wires as short as possible.
• Use a DC power supply with safety measures against high-voltage spikes (safety extra low-voltage
circuits on the secondary side).
• Check the following confirmations again before turning on the power supply.
• Is the voltage and polarity of the power supply correct? (24 VDC)
• Is the load of the output signal not short-circuited?
• Is the load current of the output signal appropriate?
• There is no the mistake found in wiring?
• Is the voltage and polarity of the Encoder power (ENC0_VDD/GND ENC1_VDD/GND) supply?
(5 VDC)
Ground
• Confirm the internal circuit is written in this manual or Instruction Sheet.
• When the connected camera to the Sensor Control comes packaged with a base, make sure to
mount with the base. Since the enclosure 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 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 con-
necting it with a building beam, the controller might be adversely affected.
• Check wiring again before turning on the FH Sensor Controller.
• Do not ground the plus (+) terminal of the 24 VDC power source when the following Sensor Control-
lers are connected to the FH-SC12/FH-SM12 (12 megapixels). Doing so may cause a short circuit of
the internal circuit, resulting in a malfunction.
• FH-1000 series
• FH-2000 series
• FH-3000 series
• FH-5000 series
• FH-L series
• Do not ground the plus (+) terminal of the 24 VDC power source when the following Sensor Control-
lers are connected to the FH-MT12 with a USB cable. Doing so may cause a short circuit of the inter-
nal circuit, resulting in a malfunction.
• FH-1000 series
• FH-2000 series
• FH-3000 series
• FH-5000 series
• FH-L series
• When using the Sensor Controller and external devices such as monitors, USB connection devices,
and RS-232C connection devices, their ground potentials should be same. If not, it may cause mal-
function.
Ground the Sensor Controller and external devices so that both electrical potential will be equal.
