CHAPTER 2: INSTALL ATION/CONFIGURATION

When the “Y contactor maximum ON time” timer expires or the current has fallen below a pre-defined value, set
by threshold 4 (typical specific) in WinESG parameterization/device setting panel or Modbus function code 6
register 21, the EntelliPro contact output relay 23 will de-energize; contactor Y opens, opening the Wye
connection. When the Y contactor feedback is removed, and after the “Y to D switchover time” timer expires
contactor K2, controlled by EntelliPro ES output relay 43, will close, connecting the motor in a Delta
configuration.
When an OFF command is received, the EntelliPro ES output relays 43, 45 and 23 open, contactor K3, Y and K2
open and the motor stops.
The “Y contactor maximum ON time” and “Y to D switchover time” are configurable in the WinESG
parameterization/timer panel or Modbus registers 33 and 34 respectively.
If the default configuration and the Star delta reverse typical are selected in the WinESG
parameterization/information panel shown in the illustration below or by setting Modbus function code 6
register 62 bit0 to 1 and bits 8,9,10 and 11 to 0x3,the inputs and outputs are mapped as below:
For EntelliPro ES5 types:
Input 99 is mapped to contactor 1 feedback - active high
Input 98 is mapped to contactor 2 feedback - active high
Input 97 is mapped to contactor Y feedback - active high
Input 96 is mapped to contactor D feedback - active high
Input 95 is mapped to drawer operation position - active high
Input 94 is mapped to main circuit feedback - active low
Input 93 is mapped to control circuit feedback - active low
Input 11 is mapped to command OFF - active low
Input 12 is mapped to command ON1 - active high
Input 13 is mapped to command ON2 - active high
Input 14 is mapped to external fault 1 - active high
Input 15 is mapped to external supervision - active low
Input 16 is mapped to emergency stop - active low
Input 17 is mapped to safety circuit - active low
Input 18 is mapped to mode switch local - active high
Input 19 is mapped to mode switch remote - active high
