Ormazabal cgmcosmos-p User Manual

5.2.5. Opening operation from closed position
1. Move the black slider in the red area to the left, as
before (this releases the lever access so the switch-
disconnector can be disconnected).
2. Disconnection operation
a. Manual operation (B driving mechanism). Insert
the lever in the switch access (red area), move the
actuating arm to the end and turn anti-clockwise
90°.
b. Motorised operation (BM driving mechanism).
Activate the corresponding operation command.
When, for any reason, the motor stops halfway through
a motorised operation, before restarting it you must
nish the operation manually, so that the whole
mechanism: sensors, controllers, etc. are in a reliable,
eective and logical position for the control system of
the motorised unit when it is switched back on.
