Damping
Damping (P080) controls the speed at which the displayed readings and output functions
respond to changes in their respective input function; load, speed and the internal rate
signals. Changes in the displayed rate of material flow, material loading and belt speed
are controlled by the damping. Relay alarm functions based on input functions of flow,
load and speed, respond to the damped value.
If the specific mA output damping parameter (P220) is enabled (value other than 0), then
the damping (P080) as it pertains to the mA function is overridden, and the output value
and bar graph respond independently at the specified mA output damping rate (P220).
Analog Output
The BW100 provides one isolated analog output. The output can be assigned (P201) to
represent rate, load or speed. The output range can be set to 0 - 20 mA or 4 - 20 mA
(P200). The 0 or 4 mA value corresponds to empty or zero condition, whereas the 20 mA
value corresponds to the associated design value: rate (P011), load (P952) or speed
(P014). The analog output can be limited for over range levels of 0 mA minimum and 22
mA maximum (P212 and P213 respectively). The output 4 and 20 mA levels can also be
trimmed (P214 and P215 respectively) to agree with a millammeter or other external mA
input device.
The BW100 LCD provides a bar graph as a function of analog output. It displays the mA
value as percentage of the mA range.
The mA output value can be tested using parameter P911. Refer to
page 62.
