1 References : pages / and / page /5 Presentation Functions Pressure switches type XMX and XMA are switches for control circuits, with an adjustable differential. They are used to control the pressure of water and air, up to 5. Equipment fitted to various models Location of setting screw Pressure switches type XMX have an internal setting screw, only accessible after removing the cover. Pressure switches type XMA have an external setting screw, accessible without removing the cover. Case Pressure switches type XMX have a black opaque case. Pressure switches type XMA can have a transparent case or a black opaque case. Setting When setting XMX or XMA pressure switches, adjust the switching point on rising pressure (PH) first and then the switching point on falling pressure (PB). Switching point on rising pressure The switching point on rising pressure (PH) is set by adjusting screw-nut. Switching point on falling pressure The switching point on falling pressure (PB) is set by adjusting screw-nut. / Te
