Danfoss AK-SM 850 User Manual

Zone Name: Custom description (User Def) or select from a drop
down list
User Dened Name: Enter required name
Photocell: None (no photocell), Inside photocell, Outside
photocell or Skylight
Control Sensor: Min: The lowest-reading photocell at any given
time will be used as the control sensor. Max: The highest-reading
photocell at any given time will be used as the control sensor.
Average: All photocells are averaged, and the average value is
used as the control sensor value. Photocell ID#1 (etc.): If any
specic photocell is selected , its value alone will be used as the
control sensor value.
Num of Schedules: The number of schedules for this point.
Control Method: Schd and photo: For this point to be on, two
conditions have to be satised: (1) the schedule must be true; and
(2) the photocell must be above trip level. Once those two
conditions are satised, the pre-delay timer will start. Schd or
photo: For this point to be on, either of two conditions must be
satised: (1) the schedule must be true; or (2) the photocell must
be above trip level. Once one of those two conditions is satised,
the pre-delay timer will start.
Tip! For outside lighting control via photocell, the light level needs
to be below the trip level. In the case of interior lighting, turn o
lights when we’re above a trip level.
Num of control relays: Each zone is controlled by a relay output
(digital output) on the I/O network.
Trip Level %: The % level at which the photocell condition will be
true and act to turn the lights on. (If multiple relays are congured,
there will be one trip level per relay.)
Range: +/-: The range selected creates a dead band.
Pre Delay: When lights are o, the number of minutes that the
lighting condition must be satised before lights will be turned
on.
Post Delay: When lights are on, the number of minutes that the
lighting condition must be false before lights will be turned o.
Minimum on Time: When lights are turned on, the number of
minutes that they must remain on before being turned o.
Minimum o Time: When lights are turned o, the number of
minutes that they must remain o before being turned on.
Override Switch: (Yes / No) Whether or not there is an override
switch assigned to the zone.
Override Duration: The duration of an override when the
override switch is used.
Burglar Override: When this zone’s lights are turned o, whether
they are to be turned on when a monitored burglar alarm is
sensed.
Fire Override: When this zone’s lights are turned o, whether
they are to be turned on when a monitored re alarm is sensed.
There is no pre-delay for re alarms.
Enable Dimmer output: Whether or not a dimmer variable
output will be controlled.
Target %: The photocell level that the controller will seek to
maintain by operation of the dimmer.
Minimum output (0.0v): The minimum dimmer level.
Maximum output (10.0v): The maximum dimmer level.
Algorithm sensitivity:
Algorithm interval:
Max rate of change (% / Sec):
Tip! Target % applies if ‘inside’ or ‘outside’ photocell used. If a
skylight photocell used, then the min output/max output (slope
between 2 points) approach is enabled.
Schedules:
Type 1: Standard (directly linked with AK-SC lighting sched-
ule), Relative (a time that is dened before or after the scheduled
start / stop times).
Start1: Scheduled Start time
Stop 1: Scheduled Stop time
Days 1: Days of the week that will apply to this schedule
Holidays: Holidays that will apply to this schedule
