Advantage of the “Zero hysteresis” patented circuit:

ensures reliable switching without wasting energy

Switch OFF level = Switch ON level.

Patented “Zero Hyseresis” circuitry

ensures reliable switching without

wasting energy.

“Traditional” light dependent relays

incorporate switching hysteresis to

prevent malfunctioning or tripping.

This results in an unnecessary delay in

switching off, and a resulting waste of

energy (over period T).

Notes

1. It is good practice to try to achieve a correct installation where the light emitted from the lamp(s) does not influence the light level seen by the

light sensor, although the “light feedback compensation” principle will help when this is not fully achievable. In this case it should be appreciated

that the “light feedback compensation” principle may delay slightly the time of Switch Off - beyond the ideal.

2. The compensation principle is not effective where the combined effect of the ambient light and the controlled lighting exceeds a maximum value

(200 lux for the 11.91, 160/2,000 lux for standard/high range of the 11.41).

3. The 11.41 and 11.91 types are compatible with gas discharge lamps that attain full output within 10 minutes, since the electronic circuit

monitors lamps' light output over a 10 minute period to achieve a true assessment of its contribution to the overall lighting level.

Advantage of the “light feedback compensation” principle:

avoids the effect of the lamps repeatedly “hunting” between On and Off, due to poor installation

Functions 11.91

11 Series - Light Dependent Relay 12 - 16 A

All the functions and the values can be set through the front joystick and are displayed on the front LCD.

Display mode

During normal operation, with AC supply connected, the following is displayed:

- the current time

- the current lux level (upper bars)

- the set lux threshold (lower bars)

- the status (open/closed) of the 11-14 output contact

- the “moon” symbol (only if the current lux level is lower than the set threshold). It also indicates that the Auxiliary

output is On, although the main output contact 11-14 may be On, depending on the chrono program.

- the “chrono” symbol (only if a switch-off time is enabled).

From Display mode it is possible to enter Program mode or Set-up mode with a short or long (> 2s) press respectively, to

the joystick centre. From Display mode it is also possible to enter Hand mode, where (independently of the lux level and

the Chrono program) the 11-14 output contact is forced into the On or Off position with a long (> 2s) press of

the joystick upper or lower quadrants, respectively. The “hand” symbol is then displayed. A long press to the opposite

quadrant will reset the hand mode.

Program mode

In this mode it is possible to set the lux threshold level, to enable and to set the switch-off time, to enable and to set the

switch-on time. With a short press to the joystick right or left quadrant it is possible to progress from one program step to

another (accepting the values set). At any program step it is possible to modify the set values with a short press to the

joystick upper or lower quadrant. A long (> 1s) press allows the fast increment (or decrement) of values. A short press to the

joystick centre will resume the display mode.

Set-up mode

In this mode it is possible to set the current year, month, day, hour and minute (in this order) and to enable european

“Daylight saving”.

With a short press to the joystick right or left quadrant it is possible to progress from one set-up step to

another (accepting the values set); in any step it is possible to modify the set values with a short press to the joystick

upper or lower quadrant. A long (> 1s) press allows the fast increment (or decrement) of values.

A short press to the joystick centre will resume the display mode.

Note: the product is supplied with central european time factory set and “Daylight saving” enabled.

Power-off mode

If the 230 V AC supply is not connected, the relay enters power-off mode and to ensure the long life of the built-in

back-up battery only the clock is maintained active. The display turns off and no other operation (including light

measurement) is performed.

With a press to the joystick during power-off mode it is possible to “awaken” the device and to enter program or set-up

mode (the“electrical plug” symbol is displayed); after about 1 minute inactivity the power-off mode is resumed.

Note: with the supply not connected, the program or set-up modes absorb a higher current than the power-off

mode, thus influencing the battery life.

Auxiliary output

A solid state output at terminals Y1-Y2 is provided (rated 12 V DC, 80 mA 1 W max.): this can be used with the power

module 19.91.9.012.4000 connected by the dedicated 011.19 connector. Or, it is possible to connect a suitable

relay (for example, 38-48-49-4C-58-59 interface module) provided the coil is within the rating, and the wiring does not

exceed 40 cm length. The auxiliary output is driven exclusively by the light sensor of the device, and is consequently

independent of the time switch. With the main contact, this permits a flexible lighting system controlled by the ambient light,

both with and without the influence of the time switch function.
