Test run
12.1 Check direction of rotation
.
If provided, place indicator disc on shaft.
The direction of rotation of the indicator disc (figure M-1) indicates the
direction of rotation of the output drive.
.
If there is no indicator disc, the direction of rotation can also be observed
on the hollow shaft. For this, remove screw plug (no. 27) (figure M-2).
.
Move actuator manually to intermediate position or to sufficient distance
from end position.
.
Switch on actuator in direction CLOSE and observe the direction of
rotation:
If the direction of rotation is wrong, switch off immediately
Correct phase sequence at motor connection. Repeat test run.
12.2 Check limit switching
.
Move actuator manually into both end positions of the valve.
.
Check whether limit switching is set correctly. Hereby observe that the
appropriate switch is tripped in each end position and released again after
the direction of rotation is changed. If this is not the case, the limit
switching must first be set, as described from page 15.
If no other options (chapters 13. to 15.) require setting:
.
Close switch compartment (see page 23, chapter 16.).
