it is released
using the AUTO
command or
cycling power on
the actuator.
Screen 6
This screen displays the current GPM and the setpoint send by
the controller. The voltage signal is converted to GPM in the
actuator. This can be used to troubleshooting to verify the signal
send by the controller and to verify Setpoint vs. Actual flow.
Screen 3
A message is displayed “Y and U5 Adjusted” for 5 seconds.
Then the new Vmax value is displayed. Press ESC to continue
to the next screen or simple disconnect the device from the
actuator.
Screen 5
This screen displays the current GPM and valve position. This
is used for troubleshooting. A small valve position and big GPM
reading might indicate overpressure in the system. A small flow
and a big valve position might indicate that there is not enough
flow or pressure in the system
