Why does my Bray 6A remain in RUN 1?
If your Bray Valve Positioner remains in “RUN 1”, it could be because initialization was started from the end position, the maximum response time of 1 minute was not observed, or the network pressure is not connected or is too low. Ensure a waiting time of up to 1 minute, avoid starting initialization from the end position, and provide the necessary network pressure.
Why has my Bray Valve Positioners completely failed?
If the device function of your Bray Valve Positioners has completely failed, showing no view even on the digital display, it could be due to an inadequate electrical auxiliary power supply. Check the power supply. Also, in cases of very high continuous loads due to vibrations, the screws of the electrical connecting terminals may be loose, or the electrical connecting terminals and/or electronic components may be knocked out. Firmly tighten the screws. For prevention, install the positioner on damping pads.
What causes zero point displacement in Bray 6A?
If the zero point on your Bray Valve Positioners displaces sporadically by more than 3%, it is likely due to impact or shock loads causing high accelerations that move the friction clutch, such as from vapor shocks in vapor lines. Correct the causes for these shock loads and then re-initialize the positioner.
