For GRASSLIN’s DTSX-B-240 type ;
The DTSX Defrost Timer is identical in
function, terminal identification, and
wiring to the Paragon 8140 and Precision
6140series Defrost Timers.
The DTSX may also be used to replace
Paragon 8040 and Precision 6040 series
time terminated defrost timers .
With the addition of a remote pressure
switch, the DTSX can replace the
Paragon 8240 series and Precision 6240
series pressure terminated defrost timers.
Defrosts will be initiated at the times set
on the timer, which will accept from 1 to
over 24 defrost initiation settings per day
at 15minute intervals (8:00AM, 8:15AM,
8:30AM, etc.)
Defrost duration is settable in 15 minute
intervals from a minimum of 15 minutes
up to several hours (15 minutes , 30
minutes , 45 minutes , 1hour, 1 hour-15
minutes , etc.)
The defrost duration determines the
termination time.
In standard configuration, the contacts
between terminals 1 and 3 are normally
open and close during a defrost to
energize defrost heaters ; the contacts
between terminals 2 and 4 are normally
closed (when timer is energized) and
open during a defrost to de-energize
refrigeration and fans.
Setting Defrost Initiation Time :
Move a white tab (tripper) on the outer
dial outward at each desired initiation
time. For example, to set defrost
initiation times at 6:00AM, 11:30AM,
4:30PM and 11:00PM, move the tab
adjacent to the "M" in AM on the dial
(6:00AM), the tab that lies between
11:30AM and 11:45 AM, the tab between
4: 30PM and 4: 45PM, and the tab
adjacent to the 11:00-11:15PM marks.
Setting Maximum Defrost Duration :
Different defrost durations may be set for
each defrost initiation setting. Each white
tab (tripper) provides a 15minute interval.
The tabs that set the initiation time
provide a minimum of 15minutes of
defrost. For longer defrost duration,
move additional tabs (following in time)
from the initiation tab. For example, if a
45minute defrost is to start at 7:00AM,
move the tab outward that lies between
7:00 and 7:15 on the AM side of the dial,
and the tabs adjacent to 7:15-7:30 and
7:30-7:45. (3 tabs moved outward). The
defrost will initiate at 7:00AM and time
terminate at 7:45AM (if temperature
termination does not occur first.)
