Operation
3.1
Powering up and powering down
It is recommended to turn on power before applying pressure and to switch off power after removing pressure.
Be sure to apply the specified operating pressure(s) . Avoid pressure shocks and bring the fluidic system gradually up to the
level of operating conditions; open and close the fluid supply gently.
3.2
First use
Before starting measurement and control, make sure to expel gas from the system by flushing all fluidic lines with the
process fluid at a relatively high flow rate.
For controllers, give setpoint = 100% or use special
= 8 (valve fully open), to ensure getting the highest
possible flow rate. Control mode 8 bypasses the PID controller, which is particularly useful when having the ES-FLOW™ set
to a low capacity flow range.
