More about ROD setup
To setup the system for run-on-demand you first need to know what your system
flow requirements will be for the full compliment of tests or test systems you will
be using.
For example, you determine that all the tests you expect to be running will
require 70 gpm of hydraulic fluid flow. Therefore you will need three pumps (90
gpm) to meet this demand. Using the ROD startup procedure for the HPU model
you have, you enable the three pumps you want to run that day, setup the ROD
Setup, and start the HPU under ROD control. The HPU starts with one pump
running (the one with the lowest number of running hours) in high pressure and
the other two in standby mode.
