It is usually thought that a DC inductive load is difficult to switch on and off when compared to a
resistive load. However, the use of an appropriate spark killer enhances the DC inductive load to
almost the same performance as that for a resistive load.

However, the monitor unit displays a value even lower than the minimum value.
0 When external equipment such as a recorder is connected, its load resistance should
be 10kilohms or larger.
* The analog output terminal (AO) should never be shorted with an other terminal so
as to prevent failures.

4-2. Sensor unit mounting
When mounting the sensor unit, pay attention to the following points.
0 To connect to the sensor unit, use Rcl/Z, Rcl, and Rcl l/2 screws.
0 Mount the unit in such amanner that the flow direction of measured fluid and the
arrow marked on the sensor unit conform to each other.
* The unit can be mounted in the vertical, horizontal, or any other direction. However,
the plastic cover part should not facedownward.
l
When connecting piping to the sensor unit, use care so as to prevent foreign matter from
entering the pipes. Pay particular attention to the amount and application of sealant and
tape.

4-3. Wiring method ’
~For wiring the sensor unit and the monitor unit, use the accessory cables
Switch output
e
Accessory cable
For wiring between the sensor unit and the monitor unit, use the accessory cable.
Connect a Class 3 grounding (100 ohms or lower) to the FG terminal. However, do not
share the grounding cable for the FG terminal with strong current carrying wires.
Keep the accessory cables separated as much aspossible from noise sources such as
strong current carrying wires.
For the power line, use a 600-volt vinyl seated wire or equivalent. Use a noise filter, as
required.
Keep the monitor unit separated as much aspossible from high-voltage wires, high-
voltage equipment, and power plants.
Before wiring, confirm that the terminal block is free from chips, Vpirestrands, etc.
