Light Sensitive Switches
Using light sensitive switches can prevent the unnecessary use of
lighting circuits where sufficient daylight exists. The benefit of modular
devices is the facility to set the ambient lighting level at which
the device will operate, and as the device is fitted at the distribution
point prevent unauthorised tampering. The remote photocell unit
can be mounted up to a distance of 50 metres from the device. Two
devices are available the standard EE100 light sensitive switch and
an enhanced programmable version the EE171 that allows time clock
control also.
Principle of Operation
Both devices control lighting systems according to natural illumination;
• The user sets the working level:
• The photo cell measures the external light level
The output of the EE100 is:
• ON, when the measured level is lower than the pre-set
light level
• OFF, when the measured level is higher than the pre-set
light level
The output of the EE171 during the programmed ON time period is:
• ON, when the measured level is lower than the pre-set
light level
• OFF, when the measured level is higher than the pre-set
light level
The output of the EE171 during the programmed off time period is:
• OFF, regardless of the lighting level

The light sensitive switches include a built in time delay which avoids
unnecessary switching due to temporary factors such as car headlight
beams etc...

The programmable light sensitive switch EE171 has two main
functions:
• Light sensitive switch comprising
➀ Override selector switch to allow permanent ON or OFF, auto or
test mode
➁ Lighting range selector
➂ Potentiometer to set light level
➃ Indicator to show output switching status
• A programmer to establish the automatic operating cycle
The programmer comprises 4 keys:
➄ ON / OFF to choose whether the circuit is on or off.
➅ Prog to set the program and scroll program steps
