I know this is an old post,but I wanted to something to it.
When this code appears,the first thing to check is the battery. Make sure that the water is at the correct level. I have been on many a service call for lift interrupt and the customer "just took it off charge". You find the battery dry and hot. Add water as needed and put the unit back on a equalize charge. Provided the battery is in good shape,you should not hear from the customer again.......or at least until the battery gets low again

go in to dash display set up and change your Battery Decrempment setting from 35 to 23. this will get max battery use. I always change this parameter when i work on these units, good luck

Hi lift Boys,
207 Means the lift interrupt switch has been activated check your battery is not flat and that the lift interrupt is only activated when the battery is 80% discharged.
If your battery checks out ok then check your line contactor and key switch is functioning ok.
