Manual control:
If needed (during adjusting, function checking, failure etc.) the stuff can change setting of the
controlled body using the handwheel.
Instructions for manual control:
•
Switch the power supply off.
•
Turn the button for gear disengagement to the right by 90° (Fig. 9), the button arrow shows the
symbol of hand) what disengages the gear in the actuator. In case of lever actuator it is needed to
hold the lever to prevent the device with load against stroke to the end position.
•
Set the valve to the chosen position:
a) For actuators with manual control: push and turn the hand wheel located on
the actuator upper cover. While turning counter-clockwisely the valve is turning
in the direction "closing". 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.
b)
For actuators without manual control of the version with a stand and lever -
using the lever. After resetting of the valve put the gear disengagement button
to the 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 handwheel or the lever
to put the gears into mesh.
In case of manual control the set end positions are not mistuned.
Actuators without gear disengagement cannot be manually controlled.
4.2 Maintenance - extent and periodicity
During inspections and maintenance is needed to tighten all screws and nuts that affect the tightness and
coverage. 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 interval between two preventive inspections is four years.
The replacement of cover gaskets and gasket of an oil filling is needed in case of damage or after 6 years of the
operation.
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 - igrease HF 401/0 (GLEIT-
µ
) resp. GLEITMO 585 K
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
.
