Chroma 62180D bidirectional source and load remote commands

[Gribo]

Hi all,
 I have a Chroma ATE Bidirectional source/load unit - 100V, 600A capability. It has a battery simulator functionality, is there anyone here familiar with these units?
How can I get the unit into battery simulator through remote commands? I tried the BATT:INIT and BATT:OUTP commands, but unless the unit is already in battery mode, These commands won't do anything.
Thanks,
