Conversion of Parameter Sets
If the binary input is configured to parameter set conversion (
SEt2
/
SEt3
), parameter set 2/3 is loaded when the contact is closed, and paramter set 1
is loaded when the contact is open. The active configuration is overwritten in each case. The W2 LED lights up when parameter set 2 and/or 3 is active.
Backup Functions
If the binary input is configured to backup function (
bACK
), the momentary actual value is adopted as setpoint value when the contact is closed. Control
is inactive and the manual operation LED lights up. When the contact is open2, control is effected with the adopted setpoint value according to config-
uration.
PI Performance
The differential component of the PDPI controller type can be attenuated to such an extent by activating PI performance (configuration:
PI
=
YES
) that
practically no more derivative action occurs. As opposed to a pure PI controller, response to setpoint changes can be configured without overshooting.
This setting is advisable for control systems which include true delay time.
