4.9 Local electric control
(Fig.14)
-
Additional accessories
In case of necessity (set up,
functional check, etc.) but at
provided supply is possible to
adjust the EA by local electric
control. After switch over of mode
selector to the mode „LOCAL“ is
possible to control the movement of
output member in desired direction
by direction change over switch.
The signal lamps go out with
reaching the end position of the
appropriate direction.
5. Service, maintenance and troubleshooting
5.1 Operation
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!
•
Electric actuator requires only inconsiderable operation. The assumption for reliable operation is proper
putting into operation.
•
The operation of these EA comes out of operating conditions and usually consists of information processing
for consequential securing of required function.
•
EA can be controlled either remotely by electrics, or manually on their assembly position. Manual control is
executed via hand wheel.
•
The operators must take care for performing of prescribed maintenance and for protection of EA during
operation against harmful ambient effects and atmospheric exposure, which exceeds the scope of
acceptable effects described in part „Working conditions“.
•
Operation beyond the switching – off torque limits is not allowed.
•
It is necessary to prevent excessive heating of the surface of EA, exceeding of type label values and
excessive vibration of EA.
5.2 Maintenance – scope and regularity
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.
In case there is no leakage in the transmission box caused by damaged seal the oil filling is permanent. The
change of oil filling shall be done after 6 years of the actuator´s operation.
The oil level check must be carried out once in a 3 months interval. The oil level must reach the filling hole. Oil
capacity is1,6 l (1,5 kg).
