2-2. Notes on connections
●
Please go after turning off the power supply without fail when you connect wires.
●
Please do not energize the power supply until the installation is completed.
●
Keep the connecting cable with the instrument away from the noise source like power supply
line and I/O line for control as far as possible.
●
Conduit wiring should be the type of exclusive one, and avoid using with another line together.
●
Please connect the earthing cable securely. The earthing should be D class with single earth.
Don
’
t share with the earth of power supply system.
●
The crimp type terminal lugs that suits the terminals of this instrument is as shown in the table
below.
Width of crimp type terminal lugs Suitable crimp type terminal lugs
6.0 mm or less 1.25-3 or Y-type 1.25-3.5
2-3. Connection with strain gage applied transducer
①
Case : Connection with one point of strain gage applied load cell
● When tension load is applied with the application of tension type or universal (compression / tension) type of load cell, and output of
“
+
”
direction is required, please replace and connect "Amplifier input +
”
and "Amplifier input
–”
.
● When the total length of cable specifies more than 30 m, the accuracy may be out of warranty because the resistance of cable makes the
input voltage of the instrument decreased.
● When the length of cable is applied more than 10 m, or when the system is using the zener barrier, the CALIB value is not applicable.
● When this instrument suits the CE standard, please make sure to shield the signal cable by mounting this in the storage case or control
