INTERFERENCE SUPPRESSION FUNCTION
CAUTION
The terminals 0 - B for interference suppression function are
indicated as blank terminals with the EX-500W series (compliant
model with EMC directive of CE marking). These terminals can be
used for the interference suppression function as shown below.
However, please note that the EX-500W may not conform to EMC
directive, if you use this function and these terminals. If you want
to use the function, be sure to check whether the operation
complies with the EMC directive on your account.
Interference suppression function
Through a simple wiring change and using the interference
suppression function, up to 5 sensors can be installed side by
side. This enables multi-point measurement in a limited space.
■ Procedure
1. Turn the power OFF.
2. Connect wires as shown below.
Connect sensors using shielded cables to shorten the overall
cable length.
3. Make sure that the connections are completed correctly and
then turn the power ON.
Make sure that terminals 0 and A of the sub controllers are
properly connected. If you turn the power ON without connect-
ing these terminals, the controllers may be damaged.
4. After warm-up, make the analog output adjustment under
actual measurement conditions. (See p.7)
5. Start measurement.
* Principle of operation
Using the interference suppression function of the EX-500(W)
Series, all sensors can operate at the same clock frequency.
EX-500W only
Up to 4 sub controllers
can be connected to
the main controller.
