5 Commisioning
Before commissioning, please ensure the actuator is correctly assembled and electrically connected. (see
section 4, page 9)
CAUTION: Remove silica gel from the connection compartment
5.1 General
textbfCAUTION: During commissioning and after every disassembly of the actuator, you have to
make the mechanical preadjustment (see sction 5.3, page 13), adjust the mechanical position indi-
cation (see section 5.4, page 14), adjust the additional components (see scetion 5.5, page 14) and
adjust the end positions (see section 5.7, page 14).
ATTENTION: The torque unit is adjusted at work and must not be changed.

5.2 Switching the actuator to manual operation
The actuator is switched to manual operation by moving the hand lever (see Figure 15 u. 16) 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!
