INSTRUCTIONS: QUASAR SV Code: DYN 64.1.06

Date: 08/11/2016 Revision: 06

It is recommended to over-excite the coil with a voltage slightly above nominal for less than one second

to ensure the anti-creep system unlocks. Once it is unlocked and the lift begins to move, the supply

voltage should be reduced during the journey to lessen the coil heating.

Also, if the choice of keeping the coil excited while the lift is at a floor is taken, the voltage to the solenoid

can also be lowered. This saves energy and improves the energy efficiency of the lift.

Below is a table of recommended voltages.

All values - V

190

* This is the voltage at the rectifier output, which can vary between the values shown.

To ensure proper operation of the device, it is advisable to design a circuit such that, if the inductive

sensor does not detect the anti-creep system unlocking, the controller will try more than once to supply

current to the coil (the Dynatech D-Box makes 7 attempts before the error message appears that no

reading for the control sensor is detected).

Thus, if there is any mechanical fault preventing the sensor from being read, the same attempts to solve

the problem will be made before an error message appears on the controller.

To prevent the car from stopping due to the loss of the control sensor signal while travelling, it makes a

reading only at the floors.

In the event of a cut in the electricity supply to the electric magnet coil when the car is moving, the speed

governor will lock and the safety gear subsequently engaged.

The installation of an autonomous power system is recommended to avoid undesired engagement in the

event of a cut in the mains electricity supply.

Open the pin to enable the speed governor to turn for automatic rescue. If the pin is not released, the

governor will lock and the safety gear will engage during the rescue movement.

Use in installations with re-levelling over 20 mm: in installations with re-levelling over 20 mm, certified

switching must be used to activate the electric magnet during the re-levelling process because if it re-

levels by more than 20 mm then the governor could lock and the safety gear engage. In this case, the

switching must discriminate between re-levelling and an uncontrolled movement.

Use in installations with door pre-opening: in installations with door pre-opening, certified switching must

be used to ensure the electric magnet remains activated during the pre-opening process because if the

electric magnet does not remain activated then the governor could lock and the safety gear engage. In

this case, the switching must discriminate between pre-opening and an uncontrolled movement.

5 FIXING THE GOVERNOR TO THE FRAME

The figure on the following page displays the governor's anchoring points to the lift's frame: Measurements are given

in millimetres.

The governor must be anchored by means of four M10 screws with an 8.8 quality. Suitable lengths are between 30

and 40 mm.

It is recommended to use Autoblock nuts to prevent screws' loosening.
