Changing the Argon Flow Sensor Setpoint
On occasion, it may be desired to change the setpoint of the argon flow switch. This flow switch
indicates when the flow exceeds the minimum set value.
1)
On the digital flow sensor, press the blue ‘S’ button until “P_1” is displayed.
2) Press the up or down arrow to set the minimum flow value. Note this is in liters/min.
3) Press the blue ‘S’ button again to register the value.
4) Test the set value and the actual flow rate by turning on the gas flow. Press the ‘Gas’
button on the control pendant. Adjust the gas flow with the black knob on the flow meter to
exceed the minimum set value. The displayed flow value should display in green when the
alarm is satisfied.
