5. Service and Maintenance
5.1 Service
1. In general it is supposed that the EA is serviced by a qualified person as required in the Chapter 1!
2. After the EA is put into operation it is necessary to check whether during manipulation its surface
finishing was not damaged – the damages should be eliminated to prevent the surface
against deterioration caused by corrosion!
•
The EA requires just an insignificant service. The reliable operation is determined by the correct putting into
operation.
•
The service of the EA results from the operation conditions and generally consists in treating the information
for subsequent performing of a required function. The EA can be controlled by remote control electrically or
manually on the place of their installation. The manual control is available with a handwheel.
•
The service staff should arrange the required maintenance and prevent the actuator during operation against
impacts of environment and climate what exceed the frame of allowed influences stated in the Chapter
“Operation Conditions”.
•
It is necessary to avoid overheating of the EA surface, exceeding of parameters stated on the nameplate
and abnormal vibrations of the EA.
Manual control:
•
If the manual control is needed (adjustment, function checking, failures etc.) the staff can reset the
regulated member using the handwheel. While rotating the handwheell clockwisely the output element
moves in the direction “CLOSING”.
Electric local control: - additional equipment ( Fig.7 )
If necessary in the case of accession, function check and so on, it is possible to preset EA or change
some parameters by local electric control with secured power feeding.
It is possible to control after removing of the padlock (1). Control mode selection is changed by sequential
pressing of the button (2)
REMOTE-OFF-LOCAL to “Remote” “Shut off”, “Local”, “Shut off” , which is
displayed on 2 rows LCD (6). Signalling motion and failure of the EA is also indicated by LEDs diode (7).
Mode “Shut off” – it is possible to change some parameters in this mode in particular menus.
Mode “Local” – it is possible to control EA by the local buttons in this mode - (3)
OPEN , (5) STOP , (4)
CLOSE .
Mode “ REMOTE ” – it is possible to control EA by the commands from superior remote system
Proceeding in setup of particular parameters in the mode
“SHUT OFF” is described in the independent
amendment No. 74 1076 02, which is delivered together with EA equipped by local electric control.
When you finish the work in the “REMOTE” mode put the padlock on the button (2) again. This measure
would be received because of potential unauthorized person’s intervention.
Note: Modes of Local or Remote control is conditioned by program choices of inputs I1 and I2. In the case
that inputs I1 or I2 are programmed for “Local releasing”, it is only possible to control the EA by local
control with active input I1 or I2.
