A CXY08 can be operated in either DHV11 or DHU11 mode. Preferred mode,
according to the user guide, is DH*U*11. Maybe yours is set that way?

Switchpack E36 (10 switches, on the left when handles are "up") should
have switch 1 ON for DHV11 mode. For switchpack E38 (8 switches) a
vector of 300(octal) has switches 4 & 5 on. Switch 1 must be ON,
switch 2 must be OFF.

Never had a problem with those PSUs. YMMV (obviously!).

A *quick* skim through the user guide didn't yield anything useful.
The DHV11 tech manual can be found here

I cannot find the CXY08 manual anywhere right now.
