1. INTRODUCTION
1.1. DESCRIPTION
This equipment is to detect any type of unintended movement of the car (UCM) with the doors open.
If there is unintended movement, it opens the safety line output connected to the safety chain and
locks the overspeed governor by deenergizing the associated rotation coil and engaging the safety
gear. This corresponds to the following device in table A.1 in the standard EN 81-20: 2017.
•“Detection of unintended car movement with open doors”, with a minimum SIL of 2.
This device must be used in combination with an overspeed governor equipped with a governor
rotation locking coil. When energised, the coil allows the governor to turn and locks it when it is de-
energised. The coil must be designed to be powered continuously (100% duty cycle) at 24 VDC and
consume a current of 150-800 mA while energised.
This system compares the car door status with the unlocking zone at all times. If it detects that the
car has left the unlocking zone with open doors, it locks the overspeed governor.
Facing the appearance of an UCM, a competent technician is needed to make the installation
operational again. Once the problem causing the UCM is resolved, the "RESET" button on the SD-
BOX is pressed to re-establish the safety line and make the system operational again.
No intervention of the lift control is
needed to make the overspeed
governor coil act, as the system
described acts directly on it.
If a fault occurs in this contact or in the
coil that may pose a risk, a system
failure signal is activated to inform the
controller. When this signal is received
it prevents the lift from starting the
following travel.
If batteries are used as an auxiliary
power supply, an external charger
between the batteries and the SD-BOX must not be connected under any circumstances. The SD-
BOX is capable of charging the batteries itself.
Important
note
Do not connect a charger between the batteries and SD-BOX, it may
burn. For further details on how to connect the SD-BOX to your control
panel, please refer to “5.3 ELECTRICAL DIAGRAMS” in this manual.
Note: This manual displays partial information on the instructions for use and maintenance of this product. Please refer to the customer

4.3. GENERAL DESCRIPTION
The control button functions and the general information supplied by the LEDs and the display are
described below.
Control buttons
•RESET5: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.
•MODE6: 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.
5The RESET function will not work when the “MOTOR” input is activated.
6If the “MOTOR” input is activated, no configuration can be made.

be locked and safety gear engaged on further movement of the car.
•81: Access to the FAILURE output relay setting. For further information, please see “6.3
SETTING THE FAILURE OUTPUT RELAY”.
4.4. OPERATION DESCRIPTION
Depending on the input signals the controller receives, the SD-BOX is able to detect unintended car
movement and lock the overspeed governor only when this happens; and not during normal stops.
The basic operation is as follows:
The following input signals are needed from the lift:
•Doors closed (DOORS).
•2 independent unlocking zone sensors (LEVEL1 and LEVEL2).
•Motor contactor (MOTOR).
When the car reaches a floor, the level inputs are activated and the coil remains energised keeping
the overspeed governor unlocked. The doors open, the closed doors signal is lost and, if UCM
occurs, the level inputs will be lost. At that moment, the safety line contact opens, the coil de-
energises and the overspeed governor is locked. If UCM does not occur, the doors will be closed
and a travel made.
4.5. DESCRIPTION OF FAULTS
Once an error has occurred, the SD-BOX will inform the user through the LEDs and the display
showing the status in which the error occurred and will remain in safe mode until it is restarted.
A list of possible failures that can occur during the operation of the SD-BOX, with their possible
causes and solutions, appear in the following table.
