Low Oil Protection Circuit

From Garaventapedia

In the event of low oil and the elevator fails to reach it’s destination in the predetermined time, the elevator will return to the lower landing and shut down. This may occur due to a leak in the hydraulic line.

If the Low Oil Protection Circuit is activated, the elevator would not be able to operate without a service visit from a certified Garaventa Lift technician. This safety feature prevents possible damage to the hydraulic cylinder/motor and compromising safety of the passenger.
