Setting the Time of Day:
Rotate the timer dial clockwise to align the triangle on the
inner dial with the desired time. The triangle represents the
current time on the timer.
NOTE: The AM and PM locations on the wheel represent 6
AM and 6 PM. For example, if the triangle points to the 7
after PM, then the current time is 7 PM. If the triangle
points to the 5 before PM, then the current time is 5 AM.
DO NOT ROTATE MINUTE HAND COUNTER-CLOCKWISE
Setting Defrost Times:
Follow this procedure to configure defrost times.
1. On the timer wheel, choose a defrost starting time.
2. Slide the tripper upward that is directly above the desired
time. The timer will initiate a 15 minute defrost at the
configured time.
3. To increase the duration of the defrost,
slide up the trippers that are adjacent to the
starting time.

APPLICATION
The DTAV40 Defrost Timer is equivalent in function, terminal identification
(with appropriate terminal block label attached), and wiring to the Paragon
8140 and Precision 6140 series Defrost Timers. The DTAV40 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 DTAV40 can
replace the Paragon 8240 series pressure terminated defrost timers.
Defrosts will be initiated by programming the timer, which will accept from 1
to over 24 defrost initiation settings per day at 15 minute intervals (8:00 AM,
8:15 AM, 8:30 AM, etc)
Defrost duration is settable in 15 minute intervals from a minimum of 15
minutes up to several hours. The defrost duration determines the termination
time. In standard configuration, the contacts between terminals 1 and 3 are
normally open and closed during a defrost to energize defrost heaters; the
contacts between terminals 2 and 4 are normally closed with S1 in “A”
position and open during a defrost to de-energize refrigeration and fans.
DTAV40 Time Initiated, Remote Temperature,
Pressure or Time Terminated:
Used in electric or hot gas defrost applications where the defrost is
terminated when the coil is frost free, as sensed by a temperature or
pressure switch, even though the defrost programmed termination time
has not been reached. The time termination functions as a fail-safe and will
terminate the defrost if the temperature or pressure switch fails to do so. The
temperature or pressure switch on the refrigeration coil has contacts which
close on a temperature or pressure rise above freezing, indicating
that frost and ice have melted from the coil. Typically a wide differential
SPDT temperature switch is used with it’s normally closed contacts wired to
the fans thereby delaying the fans from coming on until the coil temperature
has dropped back to below freezing. In most applications, the contacts at
terminals 2 and 4 are normally closed with S1 in “A” position and control the
fans and refrigeration equipment or compressor. For hot gas defrost, or for
double pole switching, contacts 2 and 4 may be configured as normally open
by selecting mode “B”. Refer to wiring diagrams 1 thru 10 for
additional detail.

REPLACING EXISTING DEFROST TIMERS
The DTAV40 will replace all models of Paragon 8040, 8140,8240 Series or Precision 6040, 6140 Series and all prior Grasslin Defrost Timer models.
TERMINAL IDENTIFICATION:
The standard DTAV40 terminal identification is identical to the Paragon 8145 with the addition of the “F” terminal. Terminal identification labels are provided for the other models to be
placed over the printed numbers on the printed circuit board. From the table above, select the proper label, apply to printed circuit board and wire per the original wiring or the wiring
diagrams indicated.
“F” TERMINAL:
The DTAV40 contains a normally closed contact between terminals 1 and F. This terminal may be used to switch the fans off during a defrost rather than terminals 2 and 4. For hot gas
defrost applications, with the mode switch set to position “B”, the fans may be connected to terminal “F”.
8143 Replacement: When replacing a Paragon 8143, wire the termination thermostat to terminal X of the DTAV40 (with the 8143 label attached), and the adjacent blank terminal. The
Paragon timers are wired to terminal X and the blank terminal. If the termination thermostat is wired to terminal N of the DTAV40 temperature termination will not occur and may result
in burnout of the DTAV40. See wiring diagrams 8 & 9.
8240 SERIES REPLACEMENT: The DTAV40 may be used to replace the Paragon 8240 series defrost timers with integral pressure termination by the addition of a remote pressure
switch wired to terminals Xp and p of the DTAV40 (with an 8240 series terminal label applied). There must be no external voltage connected to the pressure switch. Set pressure
switch cut-in to the same value as set on the Paragon defrost timer being replaced. Set cut-out 6 to 14 psi below cut-in. See wiring diagrams 10 and 3.
