ŸDo not use corrosive or flammable gases or liquids with this product.
ŸPlease use within the operang pressure range (see table below). Do not apply pressure beyond the maximum recommended pressure as
permanent damage to the sensor may occur.
ŸDo not drop, hit or allow excessive shock. Even if the switch appears undamaged, internal components may be damaged and can malfuncon.
ŸTurn power off before connecng wiring. Improper wiring or a short circuit will damage the unit or cause a malfuncon.
ŸDo not use in an environment containing steam or oil vapor.
ŸThis product is not explosion-proof rated. Do not use in an environment containing flammable or corrosive gases.
ŸWiring for the pressure sensor should avoid power source and high voltage lines. If used in the same circuit, noise may cause a malfuncon.
Ÿ ESD protecon: ± 4 kV
Safety precauons. Please read before using.

VSMN/VSMP: Adjusng Pressure Setpoint
ŸUse the vacuum seng trimmer (VR) to set the “ON”
pressure. Rotate clockwise to increase the vacuum setpoint;
rotate counter-clocksiwse to decrease the setpoint.
ŸUse appropriate sized flathead screwdriver for the seng
trimmer. Gently turn the screwdriver to make adjustments.
To prevent damage to the vacuum seng trimmer, do not
force the trimmer when it comes to a stop.
