Design and principle of operation
Testing according to DINEN14597
TheTypes3374ElectricActuatorwithfail-
safe action "actuator stem extends" is tested
bytheGermantechnicalsurveillanceassoci-
ation(TÜV)accordingtoDINEN14597in
combination with various SAMSON valves.
The register number is available on request.
3.2 Communication
Serial interface
TheactuatoristtedwithanRS-232serial
interface as standard. This allows communi-
cation with TROVIS-VIEW using SSP proto-
col.
The actuator can also be tted with an op-
tional RS-485 module (see the 'Installation'
section).
Conguration

TROVIS-VIEW software. In this case, the seri-
al interface on the actuator is used to con-
nect the actuator to the computer.
