Hi everybody. I have problem with my MK188. I can´t get more delay than 20 seconds. I have tryed all combinations with jumper. I want to have delay the relay for up to 5 min. and than stop. Is it something wrong with the circuit or what can it be ?
Most likely an assembly problem.

If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.
