Operating Instructions Edition: April 1 (#)FLENDER Connecting diagram Pressure control ~ -S1 0,5bar ~ To be connected as make or break contact, as required. 5 EN Page 2 of 2 The pressure inside the hydraulic system is increased and decreased repeatedly for checking the switching point. To avoid self-readjustment of the switching point, the integrated turning lock only allows for movement of the screw when certain torque is exceeded . Spare parts It is recommended to keep only complete switches on stock as spare parts. For use in an explosion area, the pressure control can be made intrinsically safe by means of cutoff relay (see example) . Example: Cutoff relay in combination with pressure control (pressure to be monitored 0.5 bar).
