Batching
10.3 Operation
BW500 and BW500/L
124 Operating Instructions, 12/2016, A5E33482052-AD
The process continues, and when the batch total reaches the batch setpoint, the alarm event is
displayed and the assigned relay is actuated (contact opened). Typically the relay contact would
be integrated into the batch control logic to end the process.
Rate 123.4 kg/h
Relay 2 is programmed for batch setpoint, P100-2=8.
When the next batch is to be run, pressing the following keys then on the local keypad, or
providing a momentary contact closure across an auxiliary input (programmed as batch reset,
P270 = 8), sets the alarm display and resets the batch total to zero, and the relay contact to its
closed state.
Rate 0.00 kg/h
SP: 20.000
Note
The batch setpoint can be modified in RUN mode using the up/down arrow keys.
If repetitive batches are being run, the pre-act function (P568) can be enabled to automatically
trip the setpoint relay before or after the batch setpoint is reached to assure best batch accuracy.
