To Connect Transducers; Terminal Blocks - KYOWA WGA-680A Series Instruction Manual

3-3. TO CONNECT TRANSDUCERS

3-3-1. Terminal blocks

It is recommend to connect the crimp terminals with insulation coating to the terminal blocks. Use crimp
terminals with insulation coating equivalent to JIS C 2805 crimp terminal for copper wire 1.25-3.
The terminal blocks have terminal block covers. Before connecting the wires, remove the terminal block
cover.
Before connecting the crimp terminals, remove the screws.
After completing wiring to the terminal block, put the terminal block cover.
Please do not press the terminal block too strongly.
To prevent electric shock hazards, be sure to use the terminal block cover.
3-3-2. To connect transducers
Connect transducers to terminals A to E as described
in the following.
(Cable colors are KYOWA's standard color codes.)
A: Bridge excitation (+)
B: Bridge output (-)
C: Bridge excitation (-)
D: Bridge output (+)
E: Shield
NOTE
For transducer wiring, use as short as possible 4-conductor shield cable (TEDS: 6-conductor cable).
In addition, locate the transducer far apart from power lines and wirings interfered with noise.
You cannot directly connect a remote sensing transducer.
When the WGA-680A has the optional TEDS terminals, do not connect the cables for the remote
sensing transducer.
MEMO
Factory default of bridge excitation voltage is set to 2V. It can be changed to 10V. Set the voltage
applicable to transducer specifications (within recommended excitation voltage) before using the
transducer. For details, see "4-2. TO SELECT BRIDGE EXCITATION VOLTAGE."
