Set Point · Type 2371-11 - Samson 2371-10 Mounting And Operating Instructions

Operation
5.2.1 Set point · Type 2371-11
Manual set point adjustment ∙See Fig. 1 on
page 7.
The set point is adjusted for the lowest output
pressure in the delivered state. The locking
screw (12) is not tightened.
NOTICE
Set point screw screwed too tight!
The regulator is blocked and the me-
dium flow through it is restricted.
Pressure regulation is no longer pos-
sible.
Only screw the set point screw up to
the point where the spring tension
can still be felt.
How to proceed:
1. Remove the stopper. Use an Allen key
(3 mm) to undo the locking screw (12) if
it is tightened (two turns counterclock-
wise).
2. Use an Allen key (8 mm) to remove the
blanking plug (6.1).
3. Place the key through the opening to
reach the set point screw (6).
4. Turn the set point screw (to tension the set
point spring) to adjust the set point:
− Turn clockwise : Increases the pressure
set point (the output pressure rises).
− Turn counterclockwise : Reduces the
pressure set point (the output pressure
drops).
Monitor the downstream pressure at a pres-
sure gauge (see Fig. 3 on page 10).
12
The valve closes when the output pressure p
exceeds the adjusted set point.
5. Retighten the locking screw (12) to pre-
vent the set point screw (6) from being
turned.
− Reinsert the stopper.
