Operating and installation instructions
Electric thrust actuator ARI-PACO 0,85 kN
6.0 Putting the actuator into operation
6.1 Putting the actuator into operation ARI-PACO 0,85 D
Automatic operation without housing:
- For safety reasons, the actuating drive switches over to manual operation when the
housing is removed.
In order to test the functions during commissioning, the drive can be set to automatic
operation with the magnet switch A.
- Actuating direction ARI-PACO 0,85 D
6.1.1 Overload recognition ARI-PACO 0,85 D
Long-lasting, impermissibly high pressure differences in the valve can lead to overloading
witch could limit the working life of the actuating drives.
On commissioning, impermissibly high pressure differences can be determined
immediately in the windows in the transmission cover beneath the housing.
If the transmission gear wheel is displaced from the middle window position upwards or
downwards, then the pressure difference in the valve too high.
ATTENTION !
- Actuator components which rotate or move during operation.
Crushing or injury hazard!
Before putting a new plant into operation or restarting a plant after repairs or
modification, always make sure that:
- all works has been completed!
- Regional safety instructions must be observed as a matter of policy.
- hood of thrust actuator assembled.
ATTENTION !
- Before any commissioning, the correct insertion of the valves as well as the
electrical connections should be checked.
