the channel that is configured as the control sensor. When the selected
channel is not the same as the configured control channel, B1 or B2 will
appear on the selected display line of Slot
B to indicate which channel is the
configured control channel.
The display to the left shows an example of this type of configuration. The
control channel is B1. The
Gauge Select switch is set to channel
B2.Therefore, the value of the control setpoint is displayed on channel B1
and B1 is displayed on line B2 indicating that channel B1 is the control
channel.

one of the switches.
To review a set point without affecting any output, turn the
Function
Select or Gauge Select switch to another position without changing
the displayed value.
