<font face="Arial">...or is an Off-On relay?<br>
<br>
We have a repeat-cycle relay (DH48S-S) that runs a water pump on a
preset on-off cycle. Yesterday it stopped working so I grabbed
the spare and swapped it out, being sure to copy the settings from
the old one to the new. Turned on the power and the display
started counting so all is well.<br>
<br>
Until too-early today I noticed the pump was running way too
much. Upon investigation it turns out the new relay has you enter
the times in reverse order. On the old one the left number was
time off and the right number was time on. On the new one the
time off is on the right.<br>
<br>
When people clone stuff, the least they can do is not swap the
controls around! <br>
<br>
In other news, opening up the old one didn't show any obvious
blown parts. In testing it turns out the transformer is open.
That's unusual for one that hasn't overheated (barely gets warm in
use). If I bypass the transformer I now have a working relay for
12VDC instead of 120VAC.<br>
