TORK MODEL DZS200
ASTRONOMIC CONTROLLER
Installation & Operation
INTRODUCTION
Model DZS200 is a microprocessor based time switch.
This astronomic unit is used for sunrise/sunset control
of outdoor lighting, providing two independent chan-
nels with 365 day scheduling. The unit is user settable
in 1 degree steps from 10 degrees to 60 degrees for
Northern or Southern latitudes.
In addition, the unit can be set to turn on or off from 1
to 99 minutes before or after actual sunrise or sunset
times. This compensates for longitudinal time differ-
ences and provides for more controlled lighting time
due to physical obstructions of natural light or other
special conditions.
The DZS200 may be utilized so that channel 1 pro-
vides astronomic settings for sunset to sunrise for all
night security lighting. At the same time, channel 2 can
be used for combination astronomic/straight time set-
tings. For example, store window lighting or "open and
closed" signs may be set to come on at sunset but off
during the night when no longer needed.
A unique feature of this TORK model is its momentary
contact capabilities which can be used to set each
channel individually for a user adjustable duration of 1-99
seconds. This feature is most useful for ringing school
bells, factory buzzers, sirens, or for automatic correc-
tion of clocks. Or, both channels can be used together
providing pulse output for mechanically-held contac-
tors or low voltage latching type relays – channel one
to close and channel two to open.
Up to 16 individual holiday dates can be set for special
schedules or to omit operations entirely. Likewise, 5
