5 Initialisation and
commissioning
If the GEMÜ 1436 cPos eco
is delivered fully mounted to
a valve ex works, it is already
preset at the factory (at a control
pressure of 5.5 - 6 bar without
operating pressure) and is
therefore ready for operation. A
reinitialisation (see chapter 5.2)
is recommended if the plant is
operated with a diff erent control
pressure or if the mechanical end
positions have been changed
(e.g. seal replacement on the
valve or actuator replacement).
The initialisation is retained even
in the event of voltage cutoff .
