Control buttons
•
RESET
Enables the system after the following: the first start-up, an UCM, a bypass action,
manual locking of the overspeed governor (MANUAL TRIPPING) or a fault/error.
•
MANUAL RESCUE/BYPASS: This button must be held down for more than 3 seconds to be
activated. It can be used in maintenance work and for a manual rescue if the lift has no power.
A periodic warning beep will sound while the bypass is activated. The bypass function can be
turned off by pressing the “MANUAL RESCUE/BYPASS” button again or by pressing the
“RESET” button. The maximum duration of this mode when the SD-BOX is powered by batteries
is 10 minutes, whereupon it automatically returns to a resting state. As many rescues as
necessary can be performed by pressing the button again as long as the battery has enough
charge. The maximum duration of this mode with an external power supply is not established.
MAX. 10 minutes
The maximum duration of this mode when the SD-BOX is
powered by batteries is 10 minutes, whereupon the SD-BOX
automatically returns to a resting state. To warn of the
automatic disconnection, the beep frequency increases
during the final minute.
Application of bypass
during the process of
disengaging the safety
gear
After an UCM or a manual lock (MANUAL TRIPPING), the
bypass must be applied to prevent the overspeed governor
from locking in the opposite direction when the car is moved
to disengage the safety gear.
•
MANUAL TRIPPING: This is to lock the governor during maintenance work. It is used in
combination with the “MODE” button and with an indication on the display to prevent the
governor from being locked accidentally or by mistake.
•
MODE
: This enables the use of the manual lock (MANUAL TRIPPING), the setting of the de-
energisation wait time at floor level and the output relay FAILURE.

The RESET function will not work when the “MOTOR” input is activated.
