I have a project that needs a timer relay to run
a device ON for a few seconds (30ish?) evey few minutes.

i purchased this item
http://www.dancon.com/pub/Timers/ElectronicTimer/Spec%20Sheet/DA100T.pdf

with a configured part number of DA1420A3
was told it was 0-60 seconds ON and 0-60 minutes OFF w/repeat
but the dial controls and the .pdf state it is the reverse of that and
does not repeat says the guy at Danher Controls tech supp.

before buying this unit i looked at some others I pasted my
model/part# notes below (sorry its just a jumble) which some interval
ranges are user configured by adding various values of resistor to a
pair of config terminals. the Danher guy says I can't do that with
this one or at least won't tell me how as they are configured at order
time (probably by doing just that)

rather than buying a new timer it seems there probably some simple way
to get this to repeat cycle into continuous on/off operation and was
hoping one of you gurus could show me how.

If it doesn't do what it was advertised as doing, then get your money
back, and either make them provide one that meets spec, or find another
vendor.

Good Luck!

sorry i guess i should have stated that i bought is off EBAy a couple
months back so i'm not ezpecting returns as an option and would like
to develop a plan to use what i have if possible.

I looked at the data sheet and if the part number you give is correct then
you can make it do what you want......

The 14 => 6 to 60 sec OFF
The 20 => 6.4 to 60 min ON
The A3 => 120V 50/60Hz AC or 120V DC
The blank at the end after the A3 => "standard, OFF time first, DPDT relay
Output"

The thing to note is that the output relay is DPDT which means if you use
the right contacts you _can_ invert the output so that it's it ON for
Seconds first then OFF for Mins just as you wanted.

If the blank was an 03 that would mean "one time" only so.... it appears you
DO have a standard repeating model as well.

Note the the minimium OFF time would be 6.4 Mins (eg 6 mins 24 Seconds).

thanks for your reply, it seems that the unit may be damaged then
i can only get the 0-60 second nterval working, it then switches to
the 0-60 minute "on" dial (with the red LED indicator and stays there
indefinately. i believe its possibile i could have shorted the output
while testing the lugs kept slipping off.

or

if you look under feature description it states that only the
"01" config is for coninuous operation and "00" and "03"
require toggling of the "start" switch.

since this is not a "01" model it does not repeat cycle on its own,
perhaps.

I have connected
L1 (white wire houshold power) to pins A,7, 9
and
L2 (black) to pin B and opposing side of myload1.
I have experimented with the output pins 1 or 4 or 3 or 6 to the
remaing side myload2

I get 2 results total from 4 outputs the smaller interval first and
then the LED lights at the ON timer dial (the longer interval and
STAYS permantly in that mode. (which has opened the possibilty
that i may have burned the larger interval timer circuit since the
2nd larger ON interval never completes.)

what i find confusing is that outputs 1 or 4 are identical to outputs
3 or 6 which are 2 different interval ranges.
it appears that i have a dual interval timer only half of which seems
to work which would be the smaller 0-60s "OFF" first interval (which
can be flopped as u stated depending on NO or NC conection .

No I think you missunderstand. It's NOT one timer operating each switch.
There is only _one_ relay coil and that operates the two switches together.
It like you have two switches linked together mechanically so both switch
together. In this case with your wiring I would expect "outputs 1 or 4 are


identical to outputs 3 or 6"

In the table for calculating the part number at the end of the dats sheet it
says under Features:

(Blank) = Standard, OFF Time First, DPDT
01 = ON Time First
03 = One Cycle Only (OFF Time First)
(Requires factory components)

So my interpretation is still that blank after the A3 means it's repeating.

Ok that helps...

Refer to the text below where it says ""00" Feature". It clearly says
"Repeat Repeat Cycle Timing" as it also does for feature = 01.

Only under 03 does it says "One Cycle Timing"

I think I can see the problem... Try this....

Close the control switch to start the timer running BUT _leave it closed_
don't toggle it. Just wait. Does it repeat when the timers expire?

It think it will repeat because it says "Close control switch to start
timing cycle. Open control switch to reset". eg It doesn't say toggle switch
to start. Leave it closed and see what happens.

yeah i tried both ways..second(lond) interval just stays
on permenant. like 2nd dial LED stays on too.

I even tried closing it after applying L1 to the oter points ..no
change..

toggleing doesnt work at all timer does not function at all if no
power to A and B

The Contol switch is the same as the start switch? No other switch on the
unit?

no switch at all ...thats added by the user

i took it apart. heres what it looks like.

if i can find my meter i can test some stuff like resistors caps
diodes.

I stated earlier that i connected the output to only ONE point 1 or 4
or 3 or 6 but i wonder if the 2nd interval circuit requires a load
also such that TWO output is (1 or 4) AND (3 or 6) , could this be why
the long interval is not ending properly?

the diagram shows both but what where would I connect the other OUT?

whats bugging me is that the configuration jumpers inside
could have been tampered or were even prepared by some
stoner at the factory or distributor level at purchase time.
and Eagle Signal doens't and won't provide that setup
chart such that i can check it.

it would be quit simple to check the cuts in the 3 SEVERABLE JUMPER
BLOCKS to be sure thats its not accidentally set for 0-60 hours
instead of minutes.

I asked..the guy wouldn't give.

Can you draw some kind of diagram of what you have in hand, and maybe
quote some text from labels or anything like that? I can only speak for
myself, but I'm not getting a clear picture of what we're trying to work
with here.

Thanks,
Rich

if this link works hopefully.

in a nutshell

is this timer broken?

am i not using it correctly?

was it just configured wrong at order time?
(since it is an internally custom configurable device.)

and probably how can i use it with another timer relay device
to get a recycling timer with different ON and OFF ranges
since half of this one seems to be broken or not up to my
needs.
