COMISSIONING
& PROGRAMMING
Panel. The switch used for this type of digital input must be
a momentary N .O . switch .
Momentary Override:
The digital input acts like a toggle
switch. This must also be a momentary N.O. switch. If the
time clock is on, pressing the switch turns it off, If the time
clock is off, pressing the switch turns it on.
Monitor mode:
the digital input acts as a monitor for the DI
and has no other function .
ASTRONOMICAL TIME
The Astronomical time function may be setup on any of
the channels. It controls and turns off the enabled light
channel for the daylight period form sunrise to sunset . The
following diagram illustrates the typical application of this
capability.
DIGITAL INPUT DELAY/FILTER
Enable the Digital Input Delay if you want the Digital Input to
be present for 15 seconds before it takes effect. This can
prevent cycling. Note, this delay if selected, will apply to all
eight channels .
To setup astronomical time, enter the Latitude and Lon
-
gitude parameters for the location being controlled. Also
enter the time offset from GMT (Greenwich Mean Time) .
For example, the USA Central Standard time zone is offset
-360 minutes from GMT. Madison, Wisconsin, USA is at 43°
5 minutes North (+) Latitude and 98° 30 minutes west (+)
Longitude . The GMT Offset range is + 720 Minutes . Also
click the box if applying daylight savings time to the astro
-
nomical time calculation .
Next, select the channel(s) that should have the astronom
-
ical time function and click the Enable box. This is done in
the Schedule section of the page .
Note: For non-North American Daylight Saving time set the
manual DLS (Day Light Saving) time .
CHANNEL OCCUPANT OVERRIDE
This is the number of minutes from 0 to 255 (4 hr, 15 min)
which the controller will bring a system that is Off to On
when its override button is pressed. This time can be differ
-
ent for each channel .
Occupied Override:
Select whether to allow an occupied
override and if so, whether it will be a schedule or channel
override .
HOLIDAY VANISHING
Choose whether to enable the Holiday Vanishing Feature. If
checked, the controller will make the number of days for a
holiday 0 after the holiday is over . This will keep the holiday
from occurring in subsequent years if it is not reprogrammed.
POWER DOWN PERIOD
If the controller loses power, it can remember which chan
-
nels have been overridden and how much time is remaining
in each override period . This is the amount of continuous
power loss time in minutes where the controller will re-
member the override status’. If the controller loses power
for longer than this period, the override buttons will have to
be pressed again as necessary.
INPUT VOLTAGE
The input voltage is monitored. The calibration factor is
used to scale the controller’s 24 VAC power input to the
appropriate line voltage. For example, if the line voltage is
120 VAC and the SLQ218 power input is 24 VAC, then the
calibration factor is 5.0. If the line voltage is 120 VAC and
the controller power input is 27 VAC, then the calibration
