Macro 3: Raise/Lower Trim
This macro provides a raise/lower (push button) interface for an additional Setpoint Trim. The Setpoint is
derived from the sum of ANALOG INPUT 1, ANALOG INPUT 2 and the output of the raise/lower ramp.
This ramp is controlled by the 3 digital inputs RAISE INPUT, LOWER INPUT and RESET of the
RAISE/LOWER function block.
The raise/lower trim is restricted to be +/- 10.00%. This limit is set by the MIN VALUE and MAX VALUE
parameters in the RAISE/LOWER function block.
Note that the raise/lower ramp output is automatically preserved in non-volatile memory during a
power-down
.
