Commissioning
The appropriate voltage must be supplied to the Dasy for commissioning. Therefore,
make sure that the housing is properly closed and screwed together.
Switch-on threshold
After connecting the operating voltage, move the potentiometer to the left stop
to set the switch-on threshold EON. If the outdoor brightness is at the desired level,
the potentiometer should be slowly turned to the right
until the control diode
illuminates. This process sets the switch-on threshold to the desired illuminance. The
load relay switches on after the switch-on delay has expired.
Switch-off threshold
The switchoff threshold E
OFF
is fixed at 1.5 times the value of the switch on threshold
E
ON
. If the switchoff threshold is exceeded due to increasing brightness, the control
diode and the load relay switch off once the switchoff delay time has expired.

Switch-on/switch-off delay time
As soon as the switch-on threshold is altered due to the potentiometer being oper-
ated, the switching delays are reduced to 1 second for 5 minutes. This causes the load
relay to switch almost synchronously with the control diode, to be able to check im-
mediately that the device and load are functioning correctly. Should the delay times
be activated prematurely, the power supply to the device should be momentarily
interrupted.
Instructions for function test
When the weather is sunny or if the device is installed at an unfavourable location
with a lot of natural light, covering the lens with your hand may not suffice for test
purposes. The switch-on point cannot be reached because too much light is able to
enter the housing. In these cases, use the packaging to cover the housing or another
opaque aid to create conditions which are sufficiently dark for testing.
Warranty
All professionally installed, unaltered devices are covered by warranty for the dura-
tion of the statutory warranty period from the day of purchase by the end user. The
warranty is not applicable to damage incurred during transport or caused by short-
circuit, overloading or improper use. In the event of defects in workmanship or mate-
rial being discovered within the warranty period, the company will provide repair or
replacement free of charge.
Installation and operating instructions
for twilight switches DASY 10-2/230V,
DASY 10-2/24V, DASY 10-2/12V, DASY 16-2/230V
These instructions describe the installation and commissioning of the
Dasy twilight switch. They are intended for use by electrically skilled
persons. Electrical laypersons must not install and connect devices of
this type due to the considerable potential dangers. The instructions
must be kept so that they can be referred to at a later stage.
Safety instructions
Working with and on high voltages can be potentially fatal; the extent of injury can-
not be predicted. The basic requirement for safe work and the avoidance of accidents
due to electric current (electric shock, electric arcs, secondary effects, e.g. accidents
caused by tripping) is to comply with all safety and operating requirements stated
in these instructions. The local accident prevention regulations are also applicable.
1. Installation and connection must only be carried out by an electrician.
2. When the device is opened, voltage-carrying parts (terminals) become exposed.
Touching these can cause life-threatening injury. Therefore, only open the Dasy
when the supply voltage is disconnected.
3. Ensure there are no people or animals in the danger area when manually switching
(putting the Dasy in dark conditions).
4. Avoid quick switching sequences if sensitive luminaires (e.g. HQL) are connected.
Intended use
The Dasy is intended for brightness-linked control of electrical consumers. Accord-
ing to its protection class, it is also suitable for outdoor use, in which case it must be
installed on the wall or on a mast.
Functional description
The twilight switch compares the current illuminance with the set switch-on thresh-
old. If the illuminance drops below the desired switch-on threshold, the internal relay
switch (normally opened contact) is switched on once the switch-on delay has ex-
pired. If the switchoff threshold is reached due to increasing illuminance (1.5 times
the switchon threshold), the load relay switches off again after the switchoff delay
has expired. The delay ensures that the load relay of the twilight switch does not re-
spond to brief lighting fluctuations (e.g. lightning, car headlights).
Assembly
Observe the following points when selecting the place of installation and during
mounting itself:
»
Avoid locations in direct sunlight. North and east-facing walls are ideal.
»
The light reaching the sensor must not be interrupted by overhanging roofs etc.
»
The switched light source must not directly affect the sensor.
»
Mount the device so that the warning light and potentiometer are facing
downwards.
»
Use the optional mounting kit (must be ordered separately) to mount the device
on masts or pipes.
Installation
»
In order to prevent death or injury due to electric shock, the power supply must be
cut off before installation.
»
The device’s supply line must be protected using the specified miniature
circuit breaker.
»
The cable gland on the underside or back of the device should be used for the
supply line.
»
The specified stripping lengths for the lines are given in the following diagram.
»
The silicon tubes enclosed are to be fitted to the cores of the connection lines.
»
The terminal assignment is shown in the following figure.
»
The maximum torque when tightening screw-type terminals must not be
exceeded.
