No.Q-0600-0057-05
Caution: The sensor power supply (EXCITATION) is the power supply for a sensor with VALCOM
built-in amplifier.
(If the power supply specification for the model (*2) specifies an AC power supply, the standard
specification is 12 VDC, 25 mA.)
(If the power supply specification for the model (*2) specifies a 24VDC power supply, the standard
specification is 15 VDC, 40 mA.)
.
Caution: Follow the instructions described below to avoid malfunction of the unit due to noise
caused by surge or induction
.
* Be sure to use a shielded cable as the sensor cable. When
extending the sensor cable, be sure to use a shielded cable.
* Be sure to connect the shielded wire to the terminal No. 5 with the
shortest possible leads A through D exposed from the shield.
* Avoid connecting the sensor cable in parallel with a power line, etc.
or in the same conduit.
* Securely ground the grounding terminal F.G. (frame ground).
4. Particularly Important Precautions
* Be sure to use the amplifier and sensor bearing the same serial
number.
(Otherwise, correct readings cannot be obtained.)
* Be sure to confirm that the power-supply voltage is correct, and
perform wiring correctly.
* Do not touch the diaphragm with a screwdriver, etc.
inserted through the pressure introduction port of the
sensor.
* When installing the sensor, tighten it with an appropriate torque so
that no leakage is caused.
(*Applying an excessive torque can cause a permanent set,
preventing the sensor from showing its guaranteed accuracy.
(The reading is not zeroed.))
* Do not make any modification or touch any control or switch by
opening the case unless required.
(*If you touch a control coated with red paint, preventing the
guaranteed accuracy from being obtained, we are not liable for
the failure.)
