Configuration example
L4
control unit (LG) with slave controller (FR)
The control unit (SIPART DR21) operates as a setpoint trans-
mitter and manual control unit, the slave controller (FR) SIPART
DR22 as a K-controller
If the controller following the control unit is to operate as a K-controller, a SIPART
DR22 must be used. In the SIPART DR22 an additional analog output is available
for output of the setpoint and switching inputs for tracking the manipulated variable.
In this example the control unit is structured as a K-setpoint transmitter and as an
S-manual control unit. The controller has priority with respect to manual operation
and internal setpoint presetting. The setpoint can only be preset by the LG and ac-
cepted by the FR if both LEDs Int/Ext (17) and C (18) light up. In all other cases the
value preset by the FR is only displayed in the LG. Manual operation of the LG is only
possible when the Manual LED (12) lights steadily.
