Shutdown 16—Multiposition valve is not switching
The multiposition valve has tried to switch twice without success. The valve
shuts down and reports that it is not ready (not at setpoint). Clear the shutdown
by entering a new setpoint. Possible causes include:
• The valve is not connected to the correct valve driver or is not connected at
all. Connect the valve to the correct valve driver.
• The valve is stuck.
• The switching time is too short for the speed of the valve. The valve could
be switching more slowly than usual because it is sticking slightly or the
sample is viscous. Increase the switching time.
