6.2 Manual operation
Manual operation is always useful, when the connected load is
to be operated independently of time. Press the "MANUAL"
button. The output of the AC Timer is now active (switched on,
LED a steady green), until the "MANUAL" button is pressed
again (switched off, LED flashing green).
6.3 Automatic operation
Automatic operation comprises
programmes: When the "MODE" switch is in the "1" position,
the Adapter can be used as a twilight switch (without time limit).
When the "MODE" switch is in the "2" position, the timer
switches on according to the ambient light and switches off once
the selected time has elapsed. If the "MODE" switch is in the "3"
position, the internal LDR is switched out and the unit operates
as a purely random switch.
a) MODE 1, light-dependent-only mode
Set the "MODE" switch to position "1" and the "S.C." switch
to "NOR" (= normal). The LED now flashes red. Press the
"START" button. As a result, the light-dependent resistor sen-
sor is activated. When the sensor is darkened, or twilight
occurs (in the evening), the unit switches the output on. The
8
three different switch
LED lights a steady red. The output remains switched on until
either sufficient light falls on the sensor (dawn or pocket lamp,
etc.) or the "Manual" button, the "MODE" switch or the "S.C."
switch is operated.
If the "S.C." switch is set to "REV", then the process or activati-
on is reversed: the switch switches on with sufficient light and
off with insufficient light.
b)MODE 2, light- and time-dependent mode
Set the "MODE" switch to position "2" and the "S.C." switch
to "NOR". The LED now flashes red. Press the "START" button.
As a result, the light-dependent resistor sensor is activated.
When the sensor is darkened, or twilight occurs (in the eve-
ning), the unit switches the output on at a random time. The
LED lights a steady red. After an indeterminate time the out-
put is switched off again. Should the ambient light not have
changed, the "random" process can repeat itself unpredictab-
ly often, without the "START" button having to be pressed
anew.
The output can be switched off manually, either by pressing
the "MANUAL" button or by moving the "MODE" or
"TIME/HR" switches."
If the "S.C." switch is set to "REV", then the process or activati-
on is reversed: the switch switches on with sufficient light and
off with insufficient light.
c)MODE 3, light-independent mode
Set the "MODE" switch to position "3". The "S.C." switch and
the light sensor are now switched out and are without influen-
ce. Then press the "START" button. As a result, at random
times thereafter the AC Timer output is switched on (the LED
lights a steady red) or switched off (the LED flashes red).
The output can be switched off either by pressing the
"MANUAL" button or by moving the "MODE" switch.
