Do not use corrosive or flammable gases or liquid with this product.
Please use within the rated pressure range. Do not apply pressure beyond recommended maximum pressure,
permanent damage to the pressure sensor may occur.
Do not drop, hit or allow excessive shock. Even if switch body appears undamaged, internal components may
be broken and can cause malfunction.
Turn power off before connecting wiring. Incorrect wiring or short circuit will damage and / or cause malfunction.
Do not use in environment where steam or oil vapor is present.
This product is not explosion-proof rated. Do not use in atmospheres containing flammable or explosive gases.
Avoid wiring the sensor cable adjacent to or in the same cable tray with power or high voltage lines. Doing so
could cause malfunction due to noise.
This product is not a safety sensor. Its use is not intended to protect life and prevent bodily injury or property
damage from dangerous parts or machinery. It is a normal object detection sensor.

ERROR CODE INSTRUCTION
PRESSURE UNIT CONVERSION TABLE
Turn power off and check the cause of overload current or
lower the current load under 125 mA, then restart.
Excess load current error
Residual pressure error
Applied pressure error
System Error
Change input pressure to ambient pressure and perform
zero calibration again.
Adjust the pressure within operating pressure range.
Cycle power and restart. If error condition persists
please contact factory for help.
Output load current is more than 125 mA
During zero calibration, ambient pressure is over ±3% F.S.
Applied pressure exceeds the upper limit of the
operating / set pressure range.
Applied pressure exceeds the lower limit of the
operating / set pressure range.
