Note:
The setting program enables data to be copied from the memory of parameters of the electronics DMS2 and
DMS2 ED into the computer as a file with suffix
“par”
(in the example in the figure the file
52 030.par
is created in the
directory
Flash
). The file can serve as a back-up for the case that it will be necessary to replace the position sensor in
the given actuator and to set it in the same way as the replaced one; or it can be sent as an enclosure to e-mail to the
manufacturing or service firm in solving possible problems.
9. ASSEMBLING AND PUTTING THE ELECTRIC ACTUATOR
INTO OPERATION
Upon receipt of the actuator from the factory, it is essential to check that no damage was caused during transport
and to compare the data on the actuator rating plates with those contained in the order and accompanying
documentation. Any discrepancy, defect or damage should be immediately reported to the supplier. Putting into
operation is excluded in this case. When the unpacked actuator is not immediately installed it should be stored at a dust-
free location with a temperature within the range of -25 °C to +50 °C and relative humidity up to 80% where there are
neither aggressive gases nor vapours and which is secured against the harmful effects of climatic conditions. Any
manipulation of the equipment at a temperature below -25 °C is forbidden. Storing the actuator out of doors or at
a location that is not protected against the effects of rain, snow or ice accretion is inadmissible. Before putting the
actuator into operation, excess grease should be removed. When unpacked actuators are to be stored longer than
3 months it is advisable to place a bag with silica gel or another suitable desiccant in the terminal box.
The user can only put into operation electric installations with compliance documented by a report of the initial
revision.
Before fitting in place, the actuator should be carefully inspected, particularly in case that it has been stored for
a prolonged period; the following should be checked:
– condition of parts and connections forming explosion-proof closure;
– insulation resistance of the motor winding;
– possible damage during storage.
It should also be checked that location corresponds to provisions of the par.
“Working conditions”.
If different way
of assembly is required by local conditions the manufacturer should be contacted.
The protective conductor must be connected to a protective terminal marked according to ČSN IEC 417. On the actuator,
the protective terminals are located on the body and inside the actuator, on the control board at the terminal board.
Connection
The actuator should be connected according to the wiring diagram placed inside the cover in such a way that
power supply wires have permanent good contact with the connecting terminals. The supply voltage must correspond
to the voltage stated on the rating plate of the actuator. Internal space of the cover should be clean and dry. No free
wires may stick out of the connected conductors.
Protection
Electric motors of the actuators are fitted with a built-in automatically restoring thermal protection according to
ČSN EN 600034-11. For the actuators type no. 52320 with single-phase electric motors ES 7150-2AL, ES 7130-4AL
and FCJ2B52D, it is connected in series with the electric motor winding; hence, it controls the motor directly and is not
