5. Service, maintenance and troubleshooting
5.1 Service
1
. In general it is provided that service of the EA is performed by a qualified worker in accordance with
requirement given in Chapter 1!
2. After putting the EA into operation it is needed to verify whether during manipulation any scratch on surface
occurred, it is to be removed to prevent actuator against corrosion!
The EA SP 1-Ex requires just negligible service. Proper putting into operation is a recondition of
reliable operation.
The service of the EA leads from the operation conditions and usually resides in information
processing for further arranging of required functions. EA could be controlled by electric remote control
or a manual control directly on place of installation. EA can be operated manually by hand wheal.
The stuff has to perform prescribed maintenance to prevent the EA during operation against
impacts of environment, which exceed the frame of allowed influences.
Is necessary to pay attention to avoid owerwearing of surface resisting closure EA compare to
name plate values and overvibration of EA.
Manual control:
If needed (during adjusting, function checking, failure etc.) the stuff can change setting of the
controlled body using the hand wheel. While rotating the hand wheel clockwisely the output part
moves in the direction "Z - closed".
5.2 Maintenance - extent and periodicity
During inspections and maintenance it is needed to tighten all screws and nuts which influence
tightness and protection enclosure.
Another maintenance resides in greasing. Changing or filling grease up during first years operation is
not required. To refill or to replenish the grease is needed during revisions. Intervals between two
prevention inspections are four years.
Grease:

HF 401/0 or GLEITMO 585K - gear part
ISOFLEX TOPAS

50 - operating temperature from -50

C to +40

C
Greasing of the valve spindle is independent on maintenance of the EA!
Every six months it is recommended to perform one check move in frame of adjusted operation
stroke to verify reliability of functioning with setting back to the original position.
If the audit rules do not determine else the inspection of EA is performed ones a year and tightening
of all connecting and grounded screws have to be checked to avoid overheating.
After 6 months from putting of EA into operation and once a year it is recommended to check
tightening of fixing screws between the EA and the valve. (Tighten the screws with the cross system.)
5.3 Maintenance to assure inexplosiveness
A half an hour before removing of the actuator cover it is needed to switch power supply off. The
given period is required to assure cooling of the electric motor and the space heater below the admissible
temperature value of the temperature class T6 (85 °C).
The fixing screws of the upper cover have to be always in full numbers, i.e. 8 pcs, with flexible
washers and tightly fastened.
The actuators with damaged closing surfaces, e.g. scratches, rifts, etc. have to be immediately put
out of operation.
While electric connection or disconnection of EA check the sealing of the cable bushing – demaged
and outworn sealing replace by original sealing!
Keep EA clean and pay attention on removing dirt and dust. Do the cleaning regulary according to
operating possibilities or demands.
