User manual PILZ PNOZ X7 AC

[. . . ] The unit may only be installed and operated by personnel who are familiar with both these instructions and the current regulations for safety at work and accident prevention. Follow CEN and local regulations especially as regards preventative measures. Any guarantee is void following opening of the housing or unauthorised modifications. [. . . ] Emergency stop button not operated): Relays K1 and K2 energise and latch. The safety contacts 13-14/23-24 are closed. The safety contacts 13-14/23-24 are opened redundantly. Earth faults are detected in the emergency stop circuit. Automatic reset: unit is active, as soon as the input circuit is closed. Manual reset: unit is only active, when a reset button has been pressed. The safety relay must be panel mounted (min. There is a notch on the rear of the unit for DIN-Rail attachment. If the unit is installed on a vertical mounting rail (35 mm), ensure it is secured using a fixing bracket such as end bracket. To prevent contact welding, a fuse (6 A quick / 4 A slow acting) must be connected before the output contacts. Capable capacity CL must be adhered to, otherwise the unit could malfunction. Low currents should not be switched across contacts across which high currents have previously been switched. Use copper wire that can withstand 60/75 °C. The unit must be earthed - PNOZ X7 24 VAC/DC at the connection terminal A2 - PNOZ X7 AC at the terminal marked This enables earth faults in the circuit Y1Y2 to be detected · Feedback control loop with manual reset: Connect reset button at Y1 - Y2 or connect external contactors in series The safety contacts are closed.

With capacative loads, possible current peaks are to be avoided. With DC contactors/relays use suitable spark suppression to ensure extended life of the contactors/relays. [. . . ]
