Detailed Safety Instructions
Caution
1.Do not press the setting buttons with a sharp tip. It may damage the setting buttons.
2.Do not apply excessive force to the setting buttons. It may cause damage to the button or the product itself.
3.For DIN rail mounting, use 35 mm wide DIN rails.
4.When mounting on DIN rail, install commercially available DIN rail terminal blocks on both sides of the product. Excessive vibrations and shocks may cause the product to detach from the DIN rail.
5.Do not apply excessive load to the DIN rail release lever. It may damage the release lever. In particular, when installing or removing the tube with the sensor mounted on the DIN rail, hold the unit by hand to prevent any load being applied to the release lever.
6.Do not press hard on the pressure display with your fingers. It may damage the display screen or cause the panel to come off.
7.The surface of the LED display is covered with a protective film at the time of shipment. Peel off and use as required.
8.The cartridge fitting can be attached and detached by removing the retaining pin, but make sure that the retaining pin is securely inserted during use.
Frequently Asked Questions for Pressure Sensor & Switch Series
If the pressure is not displayed on the separate display, check the following.
1)
Incorrect connection (wiring) of the connector cable
2)
Is the sensor head "analog output type"?
(Please note that the pressure indicator cannot be used with the "switch output type" sensor head.)
3)
Does the sensor type setting match the rated pressure range of the sensor head (sensor input specifications)?
Does the sensor type settings ("C-1 (compound pressure)", "C-2 (positive pressure)", "C-3 (negative pressure)") match the rated pressure range (sensor input specifications) of your sensor head ? Please check if they match. If you set a different sensor type, the correct value will not be displayed.
SED-31 sensor type setting and recommended sensor head (Reference: Excerpt from our catalog)
「C-1(compound pressure)」 VUS11-□AR
「C-2(positive pressure )」 VUS11-□A、VUS12-□A
「C-3(negative pressure)」 SEU11-□A

Damaged sensor head
If a voltage higher than the power supply (V) of the sensor head and display is applied, the sensor head and display may be damaged, and as a result, the pressure may not be displayed on the pressure display. Be sure to use it within the range of the power supply (V) of the sensor head.
