Opening and closing the shaft cover - Electric actuator LA36
Chapter 06: Using the shaft cover
Hailo e-controller for LA 36 (optional):
Attention!
- When opening or closing the cover, please first ensure that no other persons are
located in the immediate hazard area.
1. First release the locks using the operator key, as described on page 11.
2. Release the emergency off switch on the e-controller - the controller is now ready to operate.
3. To open the cover, press and hold the “Up / Open” button
- the cover now opens for as long
as the button is kept pressed, and switches off automatically when it reaches the end position. If
the button is released before then, the lid immediately stops moving.
4. To close the cover, press and hold the “Shut / Close” button
- the cover likewise only moves
as long as the button is kept pressed and stops moving immediately the button is released, and
at the latest in the end position.
The lid latch must be released before the cover can be closed.
5. When leaving the cover, the emergency off switch must be locked again in order to prevent
inadvertent activation of the cover. Screw the locks in again correctly. This is important to ensure
that the seal is pressed firmly against the frame and a watertight surface water seal is formed
.
Emergency opening:
The lower attachment point of the LA36 actuator on the frame is designed in such a way that,
when the shaft cover is in the closed position, the lid can be opened or raised easily e.g. using a
crane, as it is only in this position that the anti-removal bolt clears the attachment point. The
anti-removal bolt locks the attachment point immediately after an opening operation is started
using the LA36 actuator, with the result that the actuator cannot unintentionally slip out of the
frame bracket.
