4.3 OVERSPEED CONTACT

The governor has a built-in overspeed contact. Bearing in mind that the governor will be placed in the car, said

contact will have automatic rearming. In any case, the starting of the lift after interlocking must be carried out by a

qualified person, but without the need for direct access to the governor.

Below, a picture of the overspeed contact position is shown, where (1) is the automatic rearming contact.

WARNINGS AND SUGGESTIONS

The anti-creep system requires the lift controller to be able to manage the functions that the anti-creep system uses,

such as the coil power, control sensor monitoring and manual rescue. If the controller is unable to manage these

functions, Dynatech offers the possibility of installing an electronic module, D-Box. For more information, see the

website.

If the D-Box is not used, please observe the following warnings and follow the recommendations below for proper

controller design.

Note. It is highly recommended that the controller designer contacts Dynatech before designing the circuit to

manage the anti-creep system, to clarify any doubts regarding connections and to be recommended a specific

solution for their installation:

Locking the overspeed governor after UCM can be done by either of the following 2 methods: 1) Detecting the

UCM or 2) Letting the anti-creep system proactive.

(1) To detect the UCM, either a sensor needs to be placed on each floor or, as is the case with the D-Box, a

leveling signal needs to be used. Therefore, if the car creeps with the doors open, the sensor detects it

and cuts off the current to the anti-creep system coil, thus locking the overspeed governor.

(2) In this case, the anti-creep system clamping device is locked at each floor in the installation. When the lift

moves, the anti-creep system coil is excited and releases the overspeed governor. Then, once the car
