Tag 520 timer

We are still accepting TAG 520 timers as trade in or we will purchased them outright. This window is closing as these timers cannot be serviced.  Act soon if you want to recover any value from these timers.

Could it be that your wand is bouncing and giving multiple start signals?   Have you tried changing which wand is connected to which timer?

When we first got a set of 520’s, we were going crazy with false starts and finishes till we installed line isolation between the hill wire and timers. Never had that problem previously with our old Tag 505’s. Don’t know why the 520s were so sensitive to noise. 

possibly need to set a delay in software to ignore repeat impulses from dirty contact inside wand base.  We do this and it only take the first impulse if the wand bounces and gives multiple impulses.

no longer homologated but working good. check your parameters

What happens after a factory reset.

I would swap timers (B to A), without changing anything else, to verify if it's the timer or the wand. 

Check the lock time for the start (under parameters). You can change it to avoid this issue. 

The 520 timers are aging and no longer on the list of homologated timers. They are at the far end of their life cycle, so it is possible there's something odd going on internally. 

We had a similar problem with TIMY and Vola. TIMY sent impulse counter rather than bib # to Vola. Check under Timing Device 1/Parameters. Uncheck any boxes that are checked. 

Hi, you probably already checked it but is it the same lock time for input 1 on both timers? I usually have 1.0 sec on input 1 for the start.
Best regards,
