Preventive measures for servicing and safe operation
The following actions are required to ensure safe device function during operation:
6 months after commissioning and then once a year
• Carry out visual inspection:
Check cable entries, cable glands, blanking plugs, etc. for correct tightness and
sealing. If required, tighten cable glands and blanking plugs with torque in compli-
ance 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 re-
quired fasten screws while applying the tightening torques as indicated in the As-
sembly [}13] chapter.
• When rarely operated: Perform test run.
For enclosure protection NEMA 4X/6P
After immersion:
• Check actuator.
• In case of ingress of water, locate leaks and repair. Dry device correctly and check
for proper function.
