Repeated and sudden increase and decrease in pressure and pressure pulsation must be avoided because it could adversely affect the life of the pressure gauge. Ease the pressure fluctuation in the circuit. The pressure switch setting value is indicated with the green setting indicator. Set the pressure switch value so that the setting indicator turns clockwise. If the setting indicator passes the setting position, turn the setting indicator counterclockwise once, then reset. Set the setting with a difference of 0.1 or more from the working pressure (including pressure drop). Malfunctions could result if the difference is small. Refer to the drawings above for details on setting the setting needle. When using the pressure switch in the normal open state, the switch may not turn on when the pressure drops unless a pressure, to which the set indication error (±0.05 ), hysteresis (0.07 ), and indicated accuracy (±3%F/S) have been added, has been applied. dd the pressure gauge's indication accuracy to the maximum value of the setting indicator and indicator's error (set indicator error). When the D lamp is used, the internal voltage drop is to be 4V or less and load current 8 to 30m at 24VD. Wire the lead so that the repeated bending strain and tensile strength are not applied to the wire. Failure to do so could lead to disconnection or malfunction. void using in an atmosphere containing silicone. contact fault could result. 668
