PIDs
Configuration
The plant cascade control PIDs can be set
to compensate for any performance related
issues that are caused by the Hydraulic design
of the system, the Normal set are optimised
for the standard frame and header installation.
The PIDs can be adjusted by the Installer
(Level 2) to be Faster or Slower in response
time to the Normal settings. These Faster and
Slower settings are tolerance within 10% of
the nominal values.
For hydraulic systems that cause a faster load
capacity change in the header then the Faster
response time PIDs should be selected, for a
hydraulic system which causes a slower load
capacity change, then the Slower response
time PIDs should be selected.
