These can be mounted on all filter models. Operating pressure 0.13 MPa Once a value is displayed, it will continue to be displayed until reset, even if the pump is stopped. (Reset type) Perform element replacement when the red ring floats up and covers the entire view port. Operating pressure 0.13 MPa When a value has been displayed, it will be automatically reset when the pump is stopped. (Non-reset type) This is a visual dual-purpose. Perform element replacement when the switch has actuated (when the red ring floats up and covers the entire view port). N.. and N.O. common OM. N.O. N.. Reset button View port View port G Handling Precautions q Mounting onfirm and before mounting. Then connect so that the case is oriented downward. For maintenance, make sure to provide sufficient space above the filter for removing the element. w Operation The hydraulic fluid used becomes high viscosity when the temperature is low during the winter, etc., and the differential pressure or the switch may activate. If this occurs, wait until the oil temperature rises by a warm-up operation, then check if this is caused by clogging. Once the differential pressure is actuated, the indication continues to be displayed until the is reset (by depressing the reset button), even if the pump stops operating. Reset after replacing the element and restarting operation, or after normal operation starts in cold weather such as during winter. When using a differential pressure indication switch and if a filter clogged signal is incorporated into the sequence circuit of the machine, make sure to design the system so the filter clogged signal does not operate until normal operation starts. e Element replacement When the pressure difference reaches 0.13 MPa during operation (actuating the differential pressure ), stop operation and replace the element. When replacing the element, drain the fluid from the case. lso, check the O-rings and replace them if they are damaged. r Other Refer to the operating manual regarding the tightening torque for clamping ring. Use a commercially available hook wrench (applicable sizes 80 to 85 mm) for tightening and removing clamping rings. Refer to page 5 for Microswitch for differential pressure. 523
