12.3
mA I/O Parameters (P200 - P220)
These parameters are specific to the use of the mA output. Refer to mA Output (Page 101)for
details.
● mA output 1 is physically located at terminals 21/22 on the main board
● mA outputs 2 and 3, and inputs 1 and 2 are physically located on the optional mA I/O board
which is mounted onto the main board.
1)
In the case of assigning mA input and output functions to PID control
1)
, the following correlation
exist:
mA input
mA output
PID control 1
1
2
PID control 2

3
1)
Not available with the BW500/L.
12.3.1
P200 mA Output Range
Sets the mA range for the output selected, outputs 1 to 3 (P200 - 01 to - 03)
2)
.
Entry:
1 = 0 - 20 mA
2 = 4 - 20 mA
f
2)
BW500/L has one output, parameters will not present multiple indexes.
12.3.2
P201 mA Output Function
Assigns the mA output function for the output selected, outputs 1 to 3 (P201 - 01 to - 03)
2)
Entry:
1 = rate
f
2 = load
3 = speed
4 = PID control output
3) 4)
2)
BW500/L has one output, parameters will not present multiple indexes.
3)
Not available with BW500/L.
4)
Valid for outputs 2 and 3, only if PID system (P400) is enabled.
12.3.3
P204 mA Output Average
Sets the averaging period, in seconds, for the rate output for output 1 only.
The instantaneous mA values are averaged for the set period, and then the average value is
output during the next period while a new average is being calculated.
Entry:
0 = OFF f
1 – 999 = averaging period
