Precautions for Correct Use
When connecting the sensor controller and monitor with a switcher and splitter
Do not use devices that may require re-recognition of the monitor by the Sensor Controller
when a switching operation was performed. If such re-recognition processing happens at
switching operation, it may cause measurement time to be longer.
Connection of Terminal Block of FH-2000/FH-5000 Series
Connecting of Sensor Controller’s terminal block in order to connect package the terminal block con-
nector (male; FH-XCN).
Use the specified wire size (AWG10 to 16) and keep the power supply wires as short as possible
(Max. 2 m).
1
Insert the end of the signal line (electric wire) into the terminal block connector (male), and
tighten the three screws on the connector top to fix the wire. Recommended tightening torque:
0.7-0.8 N•m
2
Connect the wire to the terminal block connector (male) depending on the indicated terminal
block connector.

Name Function
+
DC input terminal
(+V)
Connect to the DC output terminal (+V) of 24 VDC power.
-
DC input terminal
(-V)
Connect to the DC output terminal (-V) of 24 VDC power.
FG (Functional
grounding termi-
nal) Connect to the earth.
Functional grounding is done to protect device and system
functions, including prevention of noise from external sour-
ces, or prevention of noise from devices or equipment that
could have harmful effects on other devices or equipment
• When you ground the FG, it may cause to enter noise into devices or equipment. If an equip-
ment malfunction or failure occurs, disconnect the FG from the ground and see if the condi-
tion improves.
• The outer shell of the Sensor Controller has continuity with the FG. Connecting the outer
shell to the ground may allow noise to enter the device or equipment. If an equipment mal-
function or failure occurs, remove the connection between the outer shell and the ground
and see if the condition improves.
