I don't have the diagrams for that specific model. However, most similar
Weir-Lambda SMPSUs have 4 or 5 outputs, so I expect that what you've got
has two separate +12V outputs, a single -15V output, and a single -24V
output. An odd combination, but possible. There should be two or more
terminals marked 0V, which ar the "common" terminals.

On Weir PSUs, there's usually a "Power Fail" output. It's an
open-collector (active-low) TTL-level output that goes active when the PSU
is operating normally, and INactive when the input power drops below a
level at which the PSU can regulate properly (eg becasue the mains has been
disconnected). Perhaps you have two of those.
