Rockwell Automation 1413-ME-PEA Capacitor Bank Controller - Series B - Manual (Page 34)

Publication 1413-UM001C-EN-P - May 2006
32 Installation
The auto-configure process begins. During this process, the controller
energizes each capacitor-bank step for a short time, measures the
steps kVARs and records the value. This process repeats several times
and the results of each trial are averaged. When the process is
complete, the averaged values are copied to the Effinal_StepSize_Sn
parameters and the Auto_Detect_Cap_Size flag is reset.
You must manually configure any parameters that need to change
from the default values listed in the table.
Input Interlock Mode
The Input Interlock mode allows fault protection for each capacitor
step through the use of fault-protection relays. Wire normally closed
fault-protection relays to each input from 0…10 of the controller. Wire
a normally-open momentary pushbutton to Input 11. This pushbutton
serves as a reset button.
During a fault occurrence, the controller discharges and locks-out the
respective capacitor step associated with the fault relay that tripped.
The fault-protection relay wired to Input 0 discharges and locks-out all
capacitor steps. The remaining fault-protection relays discharge and
lock-out their respective capacitor step (that is, Input 1 discharges and
locks-out capacitor step 1).
In order to place a capacitor step back into the sequence, a fault must
not be present for that step, and a reset must be initiated by pushing
the Reset pushbutton.
Manually Set Configuration Parameters
Use the DAT to manually change the controller configuration
parameters.
1. Select Integer mode.
2. Scroll to and select the desired configuration parameter.
Refer to the Control and Status Parameters table on page 27.
3. Press the Enter key to edit the parameter.
4. Use the up/down keys to change the value of the parameter.
TIP
If the data is protected or undefined, pressing the
up/down key scrolls to the next data element.
