Preventive measures for servicing and safe operation
The following actions are required to ensure safe device operation:
6 months after commissioning and then once a year
●
Carry out visual inspection:
Cable entries, cable glands, screw plugs, blanking plugs, etc. have to be checked
for correct fit and sealing. If required, tighten cable glands and blanking plugs
with torque in compliance with the manufacturer's specifications.
Check actuator for damage as well as for grease or oil leakage.
●
When deployed in areas where dust formation represents a potential explosion
hazard, perform visual inspection for deposit of dirt or dust on a regular basis.
Clean devices if required.
●
Check fastening screws between actuator and gearbox/valve for tightness. If
required, fasten screws while applying the tightening torques as indicated in
chapter <Assembly>.
●
When rarely operated: Perform test run.
●
For devices with output drive type A: Press in Lithium soap EP multi-purpose
grease on mineral oil base at the grease nipple with a grease gun.

●
Lubrication of the valve stem must be done separately.
Exception: For output drive type A in version with stem lubrication (option), the
stem is lubricated together with the output drive. If the valve manufacturer inter-
val specifications are shorter for lubricating the valve, the shorter lubrication
intervals of the valve manufacturer apply.
