Programming Port
A programming port is used to connect the unit to a hand-held
programmer or a PC for quick configuration, also can be connected
to an ATE system for automatic testing & calibration.
Auto-tune
The auto-tune function allows the user to simplify initial setup for a
new system. A sophisticated algorithm is provided to obtain an optimal
set of control parameters for the process, and it can be applied
either as the process is warming up (cold start) or as the process
has been in steady state (warm start).
Lockout Protection
According to
your
security requirement
s
, one of four lockout levels
can be selected to prevent
unauthorized changes
.
Bumpless Transfer
Bumpless transfer allows the controller to continue to control by
using its previous value
s if
a sensor
fails
.
Soft-start Ramp
The ramping function is performed during power up as well as any
time the set point is changed. It can be ramping up or ramping down.
The process value will reach the set point with a predetermined
constant rate.
Digital Filter
A first order low pass filter with a programmable time constant is used
to improve the stability of process value. This is particularly useful in
certain application where the process value is
unstable.
SEL Function
The units have the flexibility to select parameters which are most
significant
so as to
put these parameters in the front of display
sequence. There are 8 parameters
that
can be selected to allow the
user to build
a custom
display sequence.
