Yale ERP16ATF:

Hello guys, On this model have the following error message 30 RH TRACTION PMT SIGNAL AT START UP. When we put the directional lever in forward we get 2 FWD DIRECTIONAL SWITCH CLOSED. When we put the directional lever in reverse we get 3 REV DIRECTIONAL SWITCH CLOSED. We looked at all the fuses and there OK. As we don't have any information can someone give me guideline on where to start?
Many thanks in advance

Need to connect a charged battery to machine and see if codes clear and lift operates. A dead battery causes more codes than anything else in electric units. You do not need to reset controller unless it has lost the programming. With charged battery and other issues or codes come up, verify codes and post. Thanks

The hard to do we do right away. The impossible just takes a little longer.
hello fishmech, thanks for your reply. It's correct that it hes got 2 drive controllers, have controlled seat switch, accelerator switch and directional switch there all ok. Battery is indeed in a bad condition, is a minimum voltage of 2,11/cell needed to reset the controller after it has given these errors?

This lift should have two controllers, one is master and the other slave. Check all SRO switches, ie seat switch, accelerator switch and so on. Check battery voltage. I assume this is 36 volt system. Make sure the battery is reading between 38 to 39 volts. If it is reading 36 volts, battery needs to be charged. Still not working, check connection between controllers, master P21 to slave P10. Thanks.

Fact of the week
The concept of Daylight Saving Time (DST) was first implemented in Port Arthur, Ontario, Canada in 1908. The first proposal for DST, however, came in 1895 from New Zealand entomologist George Hudson who valued extra daylight so that he could hunt bugs after work during the summer months. He suggested a two-hour daylight-saving shift.
