Product details
• The Chronosense is a device intended for integration in an outdoor
type luminaire (street lighting, area lighting etc.) or to fit in a gear
tray that is mounted at the bottom of a pole.When mounted at the
bottom of a pole extra measures should be taken to protect the unit
against moisture.
• The Chronosense is a mains powered device and is using a changeover
relay to enable step-dimming.
• The Chronosense has an automatic switch-over function built in to
enable the ‘dim down’ and ‘dim up’ functionality.
This can be used during the period of the night with a relative
low traffic density in order to save energy while maintaining a
homogeneous spread of light.
• To establish the hours on which it should operate, the Chronosense
counts the hours that the power of the lights was turned on and
calculates a midpoint. It uses the midpoint of the power-on period as
a time reference point.
Note: Power on is more or less sun down, power off is more or less
sunrise, but the midpoint of the power-on period is not the same as
midnight (00:00)
• At power up the unit stays at 100% level for 10 minutes (warm-up
time of the lamp).
• The dim down times and the dim up times are specified as the hours
before and the hours after the calculated midpoint.
• The Chronosense calculates the midpoint of the power-on period by
half of the last known “On-time” value.
• When the Chronosense is connected for the first time, it needs to
synchronize for 2 days before it starts dimming.
If an unusually large deviation between the measured times occur
(i.e. power disruption), the Chronosense stops dimming and
resynchronizes during the next 2 days. After that it will again operate
as set.
• The available dipswitches can be used to:
1 Set the time that the Chronosense should dim down;
2 Set the time that the Chronosense should dim up;
3 Activate test mode.

Technical Data
General
The dim control signal activates a relay switch-over contact for dimming
purposes.The relay contact output is intended to be used in combination
with a conventional extra “dim” ballast or a multi-wattage ballast.
There is no thermal overload protection.
The Chronosense is mounted in a housing with classification IP20.
A HID-lamp must be reignited, even after a short mains power failure.
The Chronosense is equipped with a circuit that enables it to detect
short power interruptions, so appropriate measures can be taken in cases
of a short power failure.
The Chronosense accepts “Power-on” time periods between 4 and 22
hours. Shorter or longer time periods are ignored.The Chronosense
synchronizes (stops dimming) if the difference between the last recorded
time period and the average of the previous ones is more than 1 hour.
Application
• The Chronosense is designed for electro-magnetic ballasts for
70-400 W SON (-T) lamps as well as any other step-dim solution
where a switch from one circuit to another circuit is required.This
can include features like switching off the light in a certain period of
the night or switching LED drivers in or out.
• The unit is to be placed inside an outdoor luminaire or at the bottom
of a lamp post in a suitable enclosure (at least IP54).

Factory default settings
Dipswitch
The Chronosense has a six position dipswitch to set the mode of
operation (test/normal) and dim period.
Dipswitch 1,2 and 3 are used to set the dim hours before midpoint of
the night (t1)
Dipswitch 4 and 5 are used to set the dim hours after midpoint of the
night (t2)
Dipswitch 6 is used to set the mode of operation.
At factory default, all dipswitches are set to OFF:
• Dim down before midnight: 3:30
• Dim up after midnight: 5:30
• Test mode: OFF

Adjustments
By adjusting the dipswitch setting, the dim down and dim up times can
be altered.The dim down and dim up hours are defined relative to the
midpoint of the night.This is not necessarily 00:00 hours. Please check the
value for your country.

Example Chronosense
An owner of a lighting installation wants to decrease the use of energy
and chooses to optimize on the winter period.
His/her desire is to dim down at 22.00 and stop dimming at around 5:00
in the morning.
In order to choose the dipswitch settings to realize this request the next
steps are followed:
• Take the switch on/switch off times off the lighting installation on the
longest night of the year (Europe: 21 December). In example 16:45
switch on and 8:15 switch off.
• Calculate the midpoint (in example 0:30).
• Calculate the numbers of hours before midpoint (= midpoint minus
desired start dim time). In example 2 hours and 30 minutes (2:30).
• Calculate the number of hours after midpoint (= desired stop dim
time minus midpoint). In example 4 hours and 30 minutes (4:30).

• Look up the required dipswitch setting.
• Take the hours of the shortest night in the year (Europe 21 June) and
check whether the resulting dim down/ dim up hours are acceptable
in summer time (daylight saving time). Midpoint may change an hour
in case of winter/summer time adjustment.

Normal operation
Note 1: In this example the lights in the summer are switched off earlier
then the unit stops dimming.The unit is able to handle these situations.
Note 2: The mains power should be switched on and off normally.
