Note 1: The controller can be configured to limit the length of time the setpoint is
displayed. If the setpoint display blanking parameter is set to a value other than OFF, the
setpoint will be displayed for only the configured number of seconds. At the end of that
time period, the setpoint display will become blank and remain blank until the operator
presses any key. The setpoint will again be displayed for the configured number of
seconds (see 6.2.4 or 6.3.3).
Note 2: If a MODBUS master or Multi-Comm host is running a recipe based on values
stored in the host (as opposed to a recipe based on ramp/soak parameter values stored
in the controller’s database), the display will show only the PV and SV values. No other
message will alternate with either value.
