Manual control:
If needed (during adjusting, function checking, failure etc.) the stuff can change setting of the
controlled body using the handle.
Instructions for manual control:
•
Switch the power supply off.
•
Turn the button for gear disengagement to the right by 90° (Fig. 10, the button arrow shows the
symbol of hand) what disengages the gear in the actuator.
•
Set the actuator to the chosen position:
•
Push and turn the hand wheel located on the actuator upper cover. While
turning counter-clockwisely the valve is turning in the direction "open".
Having the valve in the required position turn the button for gear
disengagement to the position "motored operation" what engages the
gears. Put the hand wheel back to its original position.
Note:
After putting the button for disengaging of gearing again to the position of motor
operation if the gearing is not connected it is needed to turn the hand wheel to put the
gears into mesh.
In case of manual control the set of end positions are not detuned.
4.2 Maintenance - extent and periodicity
All screws and nuts affecting tightness and protection (IP) must be tighten during the inspection
and maintenance. Similarly, once a year should be checked and if necessary tighten mounting screws
of the terminal wires and assuring of the slip-on joints with wires.
The internal between two preventive inspections is four years.
In case of damage or after 6 years of the actuator´s operation the replacement of cover seals
and oil filling seals must be done.
The grease in the supplied actuators is designed for the lifetime of the product.
It is not necessary to change the grease during the operation of the actuator.
Lubrication:
•
- gear part – grease HF 401/0 (GLEIT-
µ
) resp. GLEITMO 585 K
•
- linear adapter – grease GLEIT-
µ
- HP 520M.
Lubrication of the valve stem is independent on maintenance of the EA!
After every potential flooding of the product check, whether there is no water inside. After eventual
water penetration, dry the product before repeated putting into operation and replace damaged
sealings, resp. other parts of EA. identically check also tightness of cable bushings and replace them,
if they are damaged.
•
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.)
•
While connecting and disconnecting of the EA check the tightness of cable glands –
those with damaged sealings should be replaced by new ones of the approved type!
•
Keep the EA clean and take care about removing impurities and dust. The cleaning has
to be performed regularly according to the operation possibilities and requirements.
