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 6.2)
is recommended if the plant is
operated with a different 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.
6.1 Electrical and pneumatic
connection
The symbols are explained in
chapter 7 “Display elements”.
1. Make the connection between pneumatic
positioner outlet
A1
(single acting) and
the pneumatic actuator control air inlet.
2. Connect the control air supply (additional
air) to the air supply connection
P
(max. 7
bar) (see chapter 4 “Pneumatic
connections”).
3. Switch on the 24V DC power supply (see
chapter 5 "Electrical connections").
