Connection Example 2 (Globe Valve) - Samson SAM -01 Mounting And Operating Instructions

   *# 

Connection example 2 (globe valve)

• Operation with single-phase alternating current (three-step control)
• Final switch-off, actuator stem extending from the actuator (direction "CLOSED"), load-de-
pendent via switch DE-S1
• Final switch-off, actuator stem retracting in the actuator (direction "OPEN"), load-dependent
via switch DE-S2 connected in series with switch WE-S3
Connecting the actuator
– Connect the grounding conductor of the
connecting line (green/yellow wire) to the
grounding conductor clamp
– N of connecting line to clamp 1.
– Control line extending actuator stem
"CLOSED" to clamp 11.
– Control line retracting actuator stem
"OPEN" to clamp 14.
– Insert jumpers; from clamp 10 to clamp 3,
from clamp16 to clamp 2, and from clamp
13 to clamp 17.

Testing the actuator
– Use a three-step controller to control the actuator.
– Use an isolated screw driver to operate the
switching rolls of the switch and check
whether the switch actually does deactivate
the motor:
With extending actuator stem ->
upper switch DE-S1,
With retracting actuator stem ->
lower switch DE-S2 and
switch WE-S3 .
– If required, switch the motor supply jumpers
on the clamps 2 and 3.
