An auxiliary pressure controller provides three channels of
forward- pressure regulation. Three modules can be installed
for a total of nine channels.
The numbering of the channels depends on where the controller
is installed. See “Auxiliary Pressure Controllers” on page 161
for details. Within a single module, channels are numbered from
left to right (as seen from the back of the GC) and are labeled on
the AUX EPC module.
