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!
·
Electric actuator requires only inconsiderable operation. The assumption for reliable ope-ration is
proper putting into operation.
·
Operation of multispeed EA results from operating conditions and usually is limited to pas-sing of
impulses to individual functional tasks.
·
In case of electric power breakdown perform set up of controlled body by hand wheel.
·
If is electric actuator connected to the circuit f automatics, it is recommended to place members for
manual remote control in the circuit, in order to control electric actuator even during breakdown of
automatics.
·
The operators must take care for performing of prescribed maintenance and for protec-tion of EA
during operation against harmful ambient effects and atmospheric exposure, which exceeds the
scope of acceptable effects described in part „Working conditions“.
·
The operation above the scope of turn-off torque moments is not permitted.
·
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
During inspections and maintenance is necessary to fasten every bolts and nuts, which effects
tightness and coverage.
Exchange oil after 500 hours of actuator´s operation. Chesk oil every quater of year. The oil level
is to reach the fillng hole. The actuator is to be filled with the gear oil .To fill the actuator up is needed
1,6 l of the oil. Once a half of year it is needed to rub teeth of gearing of the control box and bearings
where the gearings are set.
Lubrication:
·
the gearbox – oil 80, or Gyrol 75W
·
gears of transmission unit and drive mechanism on the control board – grease Gleit- μ HF 401/0
Lubrication of armature spindle is performed regardless on EA service!
·
It is recommended to perform inspection run every 6 months within set up working stroke
to verify proper function, with reverse set up of original position.
·
Unless otherwise stated in revision rules, perform inspection of EA once a year, whereby check
tightening of all connecting and grounding bolts, to prevent heat-up.
·
6 months after putting EA into operation and then once a year is recommended to check tightness
of fastening bolts between EA and armature (bolts should be tightened by cross method).
5.3 Troubleshooting
At failure of power supply the EA stops in the position where it was before the failure. If needed the
EA can be set only with the manual control (the hand wheel). After restoration of power the EA is prepared
for operation.
In case of failure of any element of the EA it can be changed by a new one. Entrust the change to a
service centre.
In case of an EA failure, which cannot be eliminated directly in operation, follow instructions for
under-guaranty and after-guaranty service.
Note: If the EA requires dismantling follow the chapter "Dismantling".
Taking the EA to pieces for repair purposes is allowed only by professionally qualified
persons trained in the production plant or by a contracted service centre!
