Profile Selection
The DS-7C was designed to be as adaptable as possible to different operating requirements. The mode of
operation, called the “profile”, can be selected by setting the Profile Select switch. A profile is selected by
aligning the arrow on the screwdriver slot of the switch with the appropriate number or letter. The following
table lists the operating characteristics of each profile.
A CHANGE IN PROFILE WILL NOT TAKE
EFFECT UNTIL THE DS-7C HAS HAD POWER REMOVED, THEN REAPPLIED.
All profiles observe the
34
°
F to 44
°
F adjustable trigger temperature. Deice functions occur when temperatures are below or equal
to the trigger temperature and precipitation is detected. Rain functions occur when temperatures are above
the trigger temperature and precipitation is detected. Profiles noted as “Low Temp Cutoff” do not initially
trigger below 15
°
F but will retrigger if triggered above 15
°
F but temperature then drops below 15
°
F.
“Delay-Off” is the minimum time the relay will remain closed after a detection. All delays are restarted by a
detection during the Delay-Off period. Functions for the external control leads for each profile are listed.
