To Next PageTo Next PageWhy Brooks SLA5860 flow cannot be achieved?
If you cannot achieve flow with your Brooks Measuring Instruments, regardless of the Setpoint, it might be due to a clogged control valve or the valve override input being grounded. Check the valve override input (Pin 12).
What to do if Brooks Measuring Instruments controller oscillates?
If your Brooks Measuring Instruments controller oscillates, the cause might be that the pressure drop or inlet pressure deviates from calibrated values. Adjust pressures to original specifications. Another reason may be unstable inlet pressure, so you should check the external pressure regulator.
What to do if Brooks Measuring Instruments output signal follows Setpoint at lower Setpoints, but does not reach full scale?
If the output signal of your Brooks Measuring Instruments follows the Setpoint at lower settings but doesn't reach full scale, it could be due to insufficient inlet pressure or pressure drop. Adjust pressures and inspect in-line filters, cleaning or replacing them as needed. Also, the sensor or valve might be partially clogged, so cleaning them is recommended.
What to do if Brooks SLA5860 output signal follows Setpoint at higher Setpoints but will not go below 2%?
If the output signal of your Brooks Measuring Instruments follows the Setpoint at higher settings but won't go below 2%, it is possible that the control valve leaks or is stuck open. Clean the control valve.
What to do if Brooks SLA5860 instrument is grossly out of calibration and flow is higher than desired?
If your Brooks Measuring Instruments is grossly out of calibration and the flow is higher than desired, the sensor may be partially clogged. Clean the sensor.
What to do if Brooks SLA5860 Measuring Instruments output stays at zero?
If the output of your Brooks Measuring Instruments remains at zero, regardless of the Setpoint, even with flow through the meter/controller, the sensor might be clogged. Clean sensor.
Why is the flow rate not achieving setpoint in my Brooks Measuring Instruments?
If the flow rate or flow signal of your Brooks Measuring Instruments fails to achieve the setpoint, it might be due to insufficient pressure drop across the MFCs. If necessary, increase the pressure.
What to do if the output signal doesn't reach full scale on Brooks Measuring Instruments?
If the output signal of your Brooks Measuring Instruments follows the setpoint at lower setpoints but doesn't reach full scale, it could be due to several reasons: * Insufficient inlet pressure or pressure drop: Adjust the pressures and inspect in-line filters, cleaning or replacing them as needed. * Partially clogged sensor: Clean the sensor. * Partially clogged valve: Clean the control valve.
What to do if flow cannot be achieved regardless of setpoint on Brooks SLA5860?
If the flow cannot be achieved regardless of the setpoint in your Brooks Measuring Instruments, it could be due to a clogged control valve. In this case, you should clean the control valve.
Why is the flow higher than desired on my Brooks SLA5860?
If the instrument is grossly out of calibration and the flow is higher than desired in your Brooks Measuring Instruments, a partially clogged sensor could be the cause. Clean the sensor to resolve this issue.
