Slave Channels Setup
Navigate to each desired slave channel and set each SP Function to
Blend, then set the desired SP Blend rate percentage referenced to the
master channels actual delivery rate. Note that the home screen shows ‘S,’
indicating selected blend slave channels.
NOTE: Once a slave channel is set to Blend, SP Rate programming is prohibited for
both keypad and serial command.
3-6-4-2 Start Blend
1. Return to the Home screen.
2. Press the START key three times. Note the 'M' and 'S' suffix now
blinking to indicate channels with blend now in process.
3. Navigate to the Master Channel Instrument Configuration screen (or via
the Setpoint hot key) and set the Master SP Rate to the desired value.
The blending process is visible on the Home screen, observing that the SP
Rate of the slave channels is the programmed proportion of the master
rate. If desired, the Home screen can be reconfigured to replace SP Rate
of the slave channels with SP Blend ratio, as described in "3-4-1 PV-SP
Measures and Status" on p. 3-7.
