What to do if Brooks SLA5863 output signal stays at approx. 5.5 Vdc or 22 mA?
If the output signal of your Brooks Measuring Instruments stays around 5.5 Vdc or 22 mA, even when the Setpoint changes, and there's flow, it could be due to a valve issue. Specifically, the valve may be leaking or stuck open. Another potential cause is +15 V applied to the valve override input. You may also check the valve override terminal (Pin 12).
How to fix controller oscillations in Brooks SLA5863?
If the controller oscillates in your Brooks Measuring Instruments, it could be due to pressure drop or inlet pressure deviating from calibrated values. Adjust the pressures to the original specifications.
Why won't the output signal go below 2% on Brooks Measuring Instruments?
If the output signal of your Brooks Measuring Instruments follows the setpoint at higher setpoints but will not go below 2%, it might be because the control valve leaks or is stuck open. You should clean the control valve.
What causes low flow on Brooks Measuring Instruments?
If the instrument is grossly out of calibration and the flow is lower than desired in your Brooks Measuring Instruments, it could be due to a partially clogged restrictor. Replace or clean the restrictor.
