12.9 Totalization (P619 - P648)
BW500 and BW500/L
178 Operating Instructions, 12/2016, A5E33482052-AD
P569 Manual Batch Pre-Act Amount
Enter a value to make the setpoint relay change state at a known value lower than the setpoint
(P564). This allows the feeding system to empty with each batch. The value of the manual pre-
Act entry is generally reflective of the material that is left in the feeding system.
Example:
Setpoint = 1000
Manual Pre-Act = 50
The setpoint relay will activate when the batch totalizer reaches 950.
P598 Span Adjust Percentage
Accessible only through manual span adjust (P019), when percent change (1) is selected. Refer
to
% Change
.
Totalization (P619 - P648)
The following parameters are specific to the use of the BW500 and BW500/L totalizers. See
“Totalization (Page 103)”.
Sets the limit, in percent of design load, below which material rates are not totalized (
f
= 3.0).
The value of 0 is reserved to allow both negative and positive totalization. Enter drop out value in
% of design load, range is 0 to 25 %.
P620 Display Zero Dropout
Activates the limit as defined in P619 ’Totalling Dropout’, below which, the rate and/or load are
set to 0.0.
-01 = Rate
-02 = Load
