Analogous repeat test towards "open" by switching over of switch S1 contacts. If any of
function is not correct, check the connection of switches according to wiring diagram.
Check of position switches (pic.7).
When the actuator moves towards "close" switch over
contacts of switches S4 (39) resp. S6 (40) by pressing of disconnecting bell (36) of relevant switch. If
the connection is properly performed, the actuator must stop when contacts of switch S4 are switched
over and light up when contacts of switch S6 are switched over. Analogous repeat test towards
"open". By pressing disconnecting bell of switches S3 (37) resp. S5 (38), the actuator must stop resp.
signalize. Again, if any of the function is not correct, connection of switches should be checked
according to wiring diagram.
3.2 Disassembly
Attention!
Before disassembly is necessary to disconnect electric supply of electric actuator!
Connection and disconnection of connectors must not be performed under the vol-tage!
Secure by prescribed way protection against connection of EA to the network and thus
potential electrical accident!
·
Turn off EA from power supply.
·
Disconnect connecting wires from terminal board of EA and release the cable from bushing. In
version with connector is enough to disconnect the connector.
·
Release fixing flange bolts and EA coupling bolts and separate EA from the armature.
·
If you will send EA to the service, pack it to sufficiently firm package, to prevent its damage during
transportation.
