Programming
The BW500 is software ready, however the controller function must be specifically programmed
in addition to programming of parameters P001 through P017.
The BW500 offers programming for two separate PID controls, 1 and 2. The controller being
programmed is identified by the suffix to the parameter number. e.g. P400-01 indicates that PID
for control system 1 is accessed.
Note
All programming should be done in the PID manua
l mode.
Access
P400-01 PID System
E
Select: 0-Off, 1-Manual, 2-Auto
0
Select 1-manual to program PID parameters
Off
disables the PID parameter set, P401 to P418. They are not accessible.
Manual
: the control output is the manual output P410.
Auto:
engages the PID controller function. This can also be done using the following key:
Note
For the mA output:
•
mA output 2 (P201-02) is normally reserved for controller 1. The signal is output at
terminals 1 and 2 on the mA I/O board.
•
mA output 3 (P201-03) is normally reserved for controller 2. The signal is output at
terminals 3 and 4 on the mA I/O board.
