Commisioning
It is assumed that the actuator has been correctly assembled and electrically connected (see Section 3, page
8).
Caution: Remove silica gel from the indicator lid.
4.1
Switching the actuator to manual operation
The actuator is switched to manual operation by moving the hand lever (see Figure 8 u. 9) by approximately
15
◦
, and by simultaneously turning the hand wheel. The lever remains in this position and will be switched
back automatically as the motor starts up.
WARNING:
•
When switching to manual operation, the actuator’s
automatic interlock is deactivated
, that
means that the driven valve must not initiate reverse torque to the output shaft of the actuator!
•
Switching back to motor operation is made
automatically
as the motor starts up. It
must not
be undertaken with the hand lever!
•
Only switch to manual operation when the motor is idle!
•
Hand lever has a slewing angle of approximately 15
◦
, therefore release the hand lever immediately
upon activation!

4.2
Monitoring the Rotating Direction
Move the actuator with coupled fittings to the middle position by hand. Give the actuator the short electrical
command “CLOSE“.
Caution:
The motor couples in automatically.
Monitoring
The output shaft must be rotating in a clockwise
direction (see direction arrows on the hand-wheel).
In the case of incorrect rotating direction:
•
With three-phase current, exchange L1 and L2.
•
With one-phase motor, exchange connections at R and L.
Warning:
The travel and torque switches do not operate if rotating direction is incorrect.
The result is destruction of the actuator and/or the fittings!!!
4.3
Setting of the Travel Switch
Caution:
: Depending on the load intensity, special actuators with high output speed display a trailing effect
when switched off. This must be taken into consideration accordingly when adjusting the travel switches. The
actuator can use either a roller-type counter or a camshaft gear for travel determination, as need be.
4.3.1
Roller-type Counter (operational range starting at 1 rev. at the output)
•
Setting the position „CLOSE“:
Move the actuator into the position „CLOSE“by hand. To set the final position, push the flasher shaft with
square cam (see Figure 10) downwards with the finger. Using a screwdriver, turn the slotted shaft of the
“R“rollers in the direction of the arrow, until the corresponding counter-clockwise trip cam activates the
travel switch (see Figure 11). Release flasher shaft and be sure that the toothed roller locks in.
