Operation - GEM 1434 mPos Operating Instructions Manual

No set value applied after initialisation
▶ Without a set value specification (for the 4–20 mA
design), once initialisation has been completed, error
message no. 2 (see "", page 28) appears, which is auto-
matically acknowledged when the set value signal > 4 mA
is applied.
Initialization is active for an unusually long time
▶ For actuators with a large air volume (filling volume), in
some circumstances it can take several minutes until ini-
tialization can be completed. Initialization is only unsuc-
cessful if an error message (see "LED messages",
page 28) appears with LED signalling.
9. Specify analogue set value 4–20 mA/0–20 mA/0–10 V.
10. Following initialisation, the process valve can be posi-
tioned in accordance with the set value signal.
* If the input has not been wired on the system side, the sep-
arately obtained initialisation kit 1434 000 ZIK can be used for
this. Alternatively, for connectors without cable, the housing
of the M12 connector, with which the product has been con-
nected, can be opened and a temporary wire bridge can be at-
tached from pin 1 to pin 5.
