tmer relay help needed

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!

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).

heres is more text not found in the pdf.

temporary available at

ftp://partsarts@divxdude.dyndns.org/book2.jpg

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.

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?

diodes.

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,
