Gen2 Regen with GDCB

Dear All,

Could you help, please?
Gen2 Regen stopped with error 713 Block by 208, the first problem happened did power supply reset then the lift ran normally for 3/4 days only. 208 error means a fault on the capacitors of DC link, but we can't find any problem on capacitors. Any an idea about this issue?
Thanks in advance

Check the batteries. Even if they read good they still need to be replaced every few years.

Dear Jluff,

which battery do you mean?

Lift OK after changed the GDCB part number ACA26800KT1.
Thanks ALL

after 3 days working well, lift again shut down with the same the error " error 713 Block by 208 "

Drive caps are getting weak. If you can source new, replace them. This is a known issue on newer drives, there is an upgraded drive available from Otis.

lift working well after replaced 3 contactors inside the drive
