Direction of rotation at mechanical position indicator: check
Figure 82: Direction of rotation of the position indicator for operation in direction
CLOSE (“clockwise closing” version)
Valve damage due to incorrect direction of rotation!
→
If the direction of rotation is wrong, switch off immediately (press STOP).
→
Eliminate cause, i.e. correct phase sequence for cable set wall bracket.
→
Repeat test run.
Check direction of rota-
tion
1.
Move actuator manually to intermediate position or to sufficient distance from
end position.
2.
Switch on actuator in direction CLOSE and observe the direction of rotation on
the mechanical position indication.
➥
The direction of rotation is correct if the actuator operation in direction CLOSE
and the symbols (
/
) turn counterclockwise.
10.6.3.
Limit switching: check
1.
Set selector switch to position Local control (LOCAL).
2.
Operate actuator using push buttons OPEN, STOP, CLOSE.
➥
The limit switching is set correctly if (default indication):
-
the yellow indication light/LED1 is illuminated in end position CLOSED
-
the green indication light/LED5 is illuminated in end position OPEN
-
the indication lights go out after travelling into opposite direction.
➥
The limit switching is set incorrectly if:
-
the actuator comes to a standstill before reaching the end position
-
one of the red indication lights/LEDs is illuminated (torque fault)
-
the status indication
S0007
in the display signals a fault.
3.
If the end position setting is incorrect: Reset limit switching.
