16 A Advantage of the “Zero hysteresis” patented circuit: ensures reliable switching without wasting energy TYPE 11.41 “ZERO HYSTERESIS” LIGHT DEPENDENT RELAYS TRADITIONAL LIGHT DEPENDENT RELAYS OFF threshold set threshold ON/OFF threshold Switch OFF level = Switch ON level. Patented “Zero Hyseresis” circuitry ensures reliable switching without wasting energy. ON threshold “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). Brightness of the natural light The NO of the light dependent relay is closed (light is switched on) Advantage of the “light feedback compensation” principle: avoids the effect of the lamps repeatedly “hunting” between On and Off, due to poor installation Light dependent relay where the lighting being controlled does not influence the light level seen by the light sensor Traditional light dependent relay where the lighting being controlled influences the light level seen by the light sensor Type 11.41 and 11.91 light dependent relay with “light feedback compensation” recalculated OFF threshold set threshold set threshold Correct functioning - provided the light sensor can be shielded from the effects of the controlled lighting switching On and Off set threshold Incorrect functioning where the lamps cycle between On and Off, because their effect is being detected by the light sensor The innovative principle of “light feedback compensation” avoids the annoying and damaging effects of the lamps repeatedly “hunting” between On and Off, due to poor installation Ambient light level as measured by the light dependent relay's light sensor. Ambient light + controlled light level as measured by the light dependent relay's light sensor. 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. 5 11 Series - Light Dependent Relay 12 - 16 A Functions 11.91 Switch-OFF time Switch-ON time Application examples Working as a standard light-dependent relay Working where lighting is not required from 10 PM onwards Working where lighting is not required between 1 AM and 5 AM Additional output - light dependent without time switch intervention 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. CHRONO lux 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. PROG CHRONO OFF SETUP 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. 6 11 Series - Light Dependent Relay 12 - 16 A 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. 19.91 power module specification Contact configuration 1 CO (SPDT) Rated current/Maximum peak current IN/Imax Rated voltage/Maximum switching voltage 16 / 30 A ( 120 A – 5 ms) UN/Umax 250 / 400 V AC Rated load AC15 (230 VAC) Nominal lamp rating (230 V): 750 VA incandescent 2,000 W compensated fluorescent Nominal supply voltage 750 W UN 12 V DC Ambient temperature range –20…+50 °C Protection category IP 20 11.31/41/42 LED Supply voltage NO output contact 11.41 / 11.42 11.31 OFF Open Open ON Open Open ON Open (timing to close in progress) Open (timing to close in progress) ON Closed Closed ON Closed (timing to open in progress) Closed (timing to open in progress) ON Fixed position (On or Off on selector) — 7 11 Series - Light Dependent Relay 12 - 16 A Outline drawings 11.31 Screw terminal 11.42 Screw terminal 11.41 Screw terminal 11.91 Screw terminal 19.91 (power module for 11.91) Screw terminal 11.91 + 19.91 power module Screw terminal 011.19 11.91 8 19.91 11 Series - Light Dependent Relay 12 - 16 A Accessories Light sensor (supplied with light dependent relay) 011.02 - Cadmium free - Non polarized - Double insulated with respect to light dependent relay supply - Not compatible with old 11.01 and 11.71 light dependent relay (to be used with 011.00 photosensor) 011.02 011.03 Flush-mounted light sensor (protection category: IP66/67) - Cadmium free - Non polarized - Double insulated with respect to light dependent relay supply - Not compatible with old 11.01 and 11.71 light dependent relay Connection cable Material PVC, flame retardant Conductor size Cable length Cable diameter Working voltage Test voltage, cable Max. temperature mm2 mm mm V kV °C 011.03 0.5 500 5.0 300/500 2.5 +90 * ring adaptor for Ø 18 mm (Ø 15 mm without adapter) Adaptor for panel mounting (supplied with light dependent relay), 35 mm wide 011.01 2-pole connector (for type 11.91 and 19.91 power module) 011.19 011.01 For direct connection of 11.91 auxiliary output (Y1-Y2) to 19.91 supply (A1-A2) 011.19 Sheet of marker tags, for types 11.31, 11.41, 11.42, 19.91, plastic, 72 tags, 6x12 mm 060.72 Identification tag, for types 11.41 and 11.42, plastic, 1 tag, 17x25.5 mm 019.01 060.72 019.01 9
