Design and principle of operation
and cannot be changed. The Type 5825 Ac -
tuator is available with fail-safe action "ac-
tuator stem extends" or "actuator stem re-
tracts" .
The actuator stem of Type 5824 Actuator re-
mains in its last position in the event of sup-
ply voltage failure.
Increased wear and shortened service life
of the actuator.
Î
Do not use the fail-safe action to control
the valve position.
A handwheel (2) is not fitted on the front
housing cover of Type 5825. Manual over
-
ride is possible, after removing the front cov-
er, using a 4 mm Allen key. The actuator re -
turns to its original position as soon as the
Allen key is released.
Testing according to DIN EN 14597
The Type 5825 Electric Actuator with fail-
safe action "actuator stem extends" is tested
by the German technical surveillance associ -
ation TÜV according to DIN EN 14597 in
combination with different SAMSON valves.
Tested versions are indicated on the name-
plate. Refer to Technical data.
The registration number is available on re-
quest.
3.2 Versions
Version with faster motor
The Types 5824-13/-23/-33 and
Types 5825-13/-23 have a more powerful
motor in a housing at the back of the actua-
tor.
3.3 Additional equipment
Limit contacts
Optionally, the actuator can be equipped
with two limit contacts. They consist of two
changeover switches. Their switching posi-
tions are changed independently from one
another by continuously adjustable cam
disks.
Limit contacts are not suitable for retrofitting.
Resistance transmitter
Optionally, the actuator can be equipped
with a resistance transmitter. It is linked to the
gear and produces a resistance signal be-
tween approx. 0 and 1000 Ω (usable range
0 to 800 Ω) proportional to the valve travel.
It can be used to assess the process of the
actuator stem.
The resistance transmitter is not suitable for
retrofitting.
