Commisioning; General; Switching The Actuator To Manual Operation - SCHIEBEL AB3 Operating Instructions Manual

Operating Instructions for Actuators Type AB with Control Unit
OM-ENGLISH-ABCSC.V1.2-16xx-V2.02-2023.04.27
CAUTION: If, during outdoor installation, commissioning is not
carried out immediately after electrical connection, the power
supply must be connected at a minimum to achieve a heating
effect. In this case, the silica gel may remain in the connection
compartment until commissioning. See section 3.3, page 11.

5 Commisioning

Before commissioning, please ensure the actuator is correctly assembled and electrically connected. (see
section 4, page 11)
NOTE: Remove silica gel from the connection compartment.

5.1 General

CAUTION: During commissioning and after every disassembly of
the actuator, you have to make the mechanical preadjustment (see
sction 5.3, page 16), adjust the mechanical position indication
(see section 5.4, page 17), adjust the additional components (see
scetion 5.5, page 18) and adjust the end positions (see section
5.8, page 18).
NOTE: 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 18 and 19) by approx-
imately 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.
Please be aware of the following items listed below, when switching to manual operation.
• 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 under-
taken with the hand lever!
