DIGITAL INDUSTRIAL CONTROLLER
english
Cascade control
Manipulated variable limiting (main controller)
COh: High manipulated variable limit
Adjustment limit: COl
≤ COh ≤ 100 (in %)
COl: Low manipulated variable limit
Adjustment limit: 0
≤ COl ≤ COh (in %)
Direction of action (Main controller)
Inv: no The main controller (PID controller 1) works with positive direction of
action
Inv: yes The main controller (PID controller 1) works with negative direction of
action
Sub-menus of the main menu option INPUT 1 (controller input 1)
Signal type

Pt100 Connection
Mode of connection of the Pt 100 sensor
Pt100 : 3 Pt 100 sensor is connected by 3 wires (3-wire technique)
Pt100 : 4 Pt 100 sensor is connected by 4 wires (4-wire technique)
If a 3-wire connection is selected the terminals 35 and 36 have to be shorted by a
wire (see connection allocation)
