SCALE LIGHT WITH EXTINGUISHING NOTICE

The timers have only 2 times available, ON time and OFF time, therefore it is not possible with a single timer to obtain, for example, a 50-second staircase light that after 40 seconds turns off for 0.5 seconds as a notice of end of time and after another 9.5 seconds goes off definitively, because this case would require programming of three times (40, 0.5 9.5 seconds).
To obtain this result there are different solutions, for example two timers can be connected IN SERIES with the two inputs connected together to have a simultaneous trigger, the first can have an ON time equal to the total cycle of 50 seconds and an OFF time 1 cent with 2 overall commutations, starting with the ON state.

The second timer, connected in series, will have an ON time 40 seconds and an OFF time of 0.5 seconds, with 4 total commutations starting with the ON state, so after switching off for 0.5 seconds it will reactivate for another 40 seconds, but the series will be interrupted after 9.5 seconds from the first timer. Another way IN SERIES is to use a first relay as a staircase light timer and a second relay in series with three ON-OFF-ON switches starting at ON, where the ON time is set at 40 seconds and the OFF time at 0.5. seconds.

The series connection of the contacts is more practical to carry out physically, but the assessments must be made on a case-by-case basis.

If you do not want the switch-off notice, you can avoid connecting the second timer or, without changing the wiring, you can exclude or put back the notice by setting the second timer as the first or as needed for the notice.

Using the third contact and / or changing the times of the timers it is possible to obtain more warning of switching off.

TIMED LIGHT USING DIVERTERS AND SWITCHES INSTEAD OF BUTTONS

When you need to time a light point in an old house where the command is given through switches or deviators, and you do not want or cannot replace the old commands with new buttons, then these permanent commands are used instead of the buttons, setting triggering of the timer on the on and off sides, so that at each change of state of the circuit-breaker or of the series of switches, a new timed cycle will occur.

FORWARD REVERSE MOTORS CONTROL

In the passage from forward to backward direction it is good to go through the completely off state, both for electrical and mechanical reasons, and this device allows you to set the duration of the off time, it is also possible to have the control with two buttons or three buttons, in both in cases it is possible to have the command in toggle on each direction so the button that turns on can also turn off and this is convenient, but it also has limits of use that can be overcome with the three-button system that allows you to turn off the engine by pressing in in any case always the same button and this is especially useful if you do not see the engine or if you do not know in which direction it is turning or if it is turning. Normally when there is an interruption of energy on return the motors must remain off and start only on explicit command, however this unit is flexible and also allows you to establish the start in a certain direction when the mains voltage is restored. It is also possible to set a maximum operating time separately for the two directions.

STUDIO LIGHT BUSY-WAIT-FORWARD

FLASHING

REDUCTION OF THE AVERAGE FLOW OF A PUMP WITHOUT USING INVERTER

Sometimes you need a pump that delivers less water than its nominal flow rate, if you do not use an inverter to regulate it, you can use a command that has a working time and a rest time, such as a flashing light, so on average it is possible to reduce the stream of water. Pay attention to the inrush of the pump which can be higher than the capacity of the smart relay contacts therefore this unit must be used to drive a relay with a higher capacity. If the load is three-phase, the three channels of the smart relay can be used, set and controlled in the same way, as long as the load current is low enough, otherwise a three-phase contactor will be used. A more advanced solution can be to set the 3 channels respectively to 25%, 50%, 75%, then with a selector select which output to use to drive the pump or the remote control, and if the selector has 4 positions, it can be added even 100% and with a fifth position even 0%.

RING TONE WITH COURTESY LIGHT

(USEFUL ALSO FOR THE DUDE)

The bell output is connected as a dead man, while the light output is a timed output and the button controls both inputs.

Whoever rings the bell will be illuminated for a certain time by the courtesy light, also useful for seeing who is from the window or from a camera.

This light can also be duplicated inside the house to let deaf people know that they have rang.

VISUAL SIGNAL OF BELL PRESSED FOR A LITTLE OR LONG TIME (USEFUL ALSO FOR THE HEARING)

FORWARD REVERSE CONTROL FOR SMALL DIRECT CURRENT MOTORS

MASCHIATORE CON TRAPANO A COLONNA

Applicazione dello smart relè per il comando della rotazione del motore di un trapano a colonna adattato per filettare con maschio sul mandrino.

Application examples

1. The elderly person with shopping bags who needs more time to climb stairs can press the light button three times for triple time;

2. In a condominium, a person who has to go down or up the stairs, finding the light already on, can make sure that he has time to get to his destination with the option of recharging the timer or adding time;

3. In a condominium, during the cleaning of the stairs, you need a long time to avoid having to turn the light back on continuously during work;

4. In a condominium with two lines of paired stair lights, by switching off the first one, you can give the switch-off notice for the second line;

5. In condominiums with a staircase light line, lights can be switched off for 0.3..0.5 seconds as a notice of time expiration;

6. If you want a timed light in an old system where there is already a switch or a two-point command with diverters, and you don't find buttons of the same aesthetic shape, you can get the same on / off + timer function using the existing commands. with diverters / switches and triggering the timer on the ON / OFF variation edges of the input;

7. In the event of voltage fluctuations during thunderstorms or in the case of systems with lamps that must not be re-ignited when hot, reconnection to the electricity grid can be delayed after the energy has been restored;

8. Returning from an absence, you could have a steady green light if there has never been a power failure and / or a flashing red light otherwise;

9. Control of the motor of an up / down / stop awning with maximum operating time in both directions and pause in changing from one to the other;

10. Courtesy indicator command, closed / wait / forward, at the door of a medical or professional office.

11. Visual indication that a bell has been rung, useful for the deaf or for people who arrive after the sound.

12. To start three-phase motors in the star-delta connection, you must first connect the motor in star for the first starting phase, then when you switch to delta you have to wait a moment for the star to release before connecting in delta.
