Safety instructions

Note
The electrical power supply and supply air pressure data
indicated on the name plate must be complied with during
commissioning.
3
Before switching on the device, make sure that your installation
3
complies with the environmental conditions listed in the chapter
"Technical Data" or on the data sheet.
If there is a chance that safe operation is no longer possible,
take the device out of operation and secure it against
unintended startup.

Checks prior to commissioning

Air pressure in the compressed air connecting line:
• 1.4 to 10 bar (20 to 145 psi)
• Marine version: 1.6 to 8 bar (23 to 116 psi)
Current input active: 4 to 20 mA

Mechanical mounting checks

During commissioning, the mechanical mounting on the linear
and rotary actuators is checked. For this purpose, the actuator is
first moved into the end positions and Auto Adjust is then
carried out.
With large actuators, it can occur that the time for automatic
adjustment is significantly than in smaller actuators.
