[Setpoint]
[Parameter switch]
Each controller can be configured as a monodirectional or bidirectional controller. Two parameter
sets are available for each controller. The 2nd parameter set is activated if the digital input 2 is set
[Control. parameter switch-over] . In this case [Parameter set 2] can be configured in the
as the
menu.
When connecting the actuator, ensure that the actuator which increases the measured value is con‐
nected to the corresponding output
the measured value is connected to the output
'Electrical installation' on page 38 .
Example: A medium with an actual value of pH 3 should have its pH increased to the setpoint pH 7
using a sodium hydroxide solution (pH >14). Therefore connect the actuator to the control output
[Increase measured value] .
