A2, E2 and S2 logics interrupting the safety device contacts
causes the gate to stop closing, then to start opening again
when the safety devices are released.
5.2.10. ELECTRONIC SAFETY DEVICE
(models 820 EMC - 860 EMC only)
The operator is equipped with a system which cuts in when
it senses a 20% reduction in pinion speed. The device inverts
the closing movement and inhibits opening movement.
When this safety device cuts in, LED S goes out for a few
seconds. Automatic re-closure is inhibited if the electronic
anti-crushing safety has cut in.
