11.1. Preventive measures for servicing and safe operation
The following measures are required to ensure safe device operation:
Every 6 months after commissioning
.
Carry out visual inspection:
–
For electrical devices: cable entries, cable glands, screw plugs, etc.
have to be checked for correct tightness and sealing.
Consider torques according to manufacturer’s details.
.
If rarely operated: perform test run.
.
For devices with output drive A, press in Lithium soap EP multi-purpose
grease on mineral oil base at the grease nipple with the grease gun
(quantities see 13, table 2). This procedure does not grease the valve
stem. Lubrication of the valve stem must be done separately.
6 months after commissioning and then once a year
Check screws between multi-turn actuator and valve for tightness. If
required, tighten by applying the torques given in table 1, page 12.
For enclosure protection IP 68 (option)
After submersion:
.
Check multi-turn actuator.
.
In case of ingress of water, dry device correctly and check for proper
function.
