ABB GJR5252300R0101 7AC91D automation controller module
Technical data of product parameters
If the absolute value of the difference between Servo Driver target position and actual position is GJR5252300R0101 7AC91D
greater than this value, a contingency condition may exist. The condition must exist until a timer
expires for it to be reported. The timer is described below:
A situation could arise where the Servo Driver target position and the Controller’s target are not
equal. One example would be if the shutdown input were true, the Servo Driver set the target
position to 0, but the Controller did not track. In this situation, contingency would not be reported GJR5252300R0101 7AC91D
if the valve went to 0% positionRedundant LVDT option. If the redundant LVDT option is selected, the Servo
Driver will execute only 1 PI control loop. However, it will continue to process
both position feedback channels, middle-selects each to reject some noise, then
high-selects between the two feedback values.
If the option is not selected (RDNDNT = 0), the Servo Driver behaves as a twoindependent-channel closed loop servo controlEach Personality module has a simplified wiring diagram label on its side, which
appears above the terminal block. This diagram indicates how the wiring from the GJR5252300R0101 7AC91D
field is to be connected to the terminal block in the base unit. The diagram for the
Servo Driver Personality module is shown in Figure 22-1.
The Small Loop Interface Module (SLIM) provides the displays, keyboards inputs,
and accompanying logic needed for the operator to monitor and control the GJR5252300R0101 7AC91D
functions of an Ovation Loop Interface module (Section 16) or an Ovation Valve
Positioner module (Section 25).
Information is presented to the operator by various bargraphs, LEDs, numeric
displays and alphanumeric displays on the front panel of the SLIM. The keyboard
allows the operator to send control information to the Ovation Loop Interface
module to control the process (see Figure 23-1).
