CHAPTER 2: INSTALL ATION/CONFIGURATION
2.32 EP OS MOTOR MANAGEMENT SYSTEM – INSTRUCTION MANUAL
If Fixed local is selected as a controlling device, any source assigned as local can control the motor (ON/OFF).
If Fixed remote is selected as a controlling device, only the remote source can control the motor (ON/OFF).
NOTE: only one control (local or remote) can be enabled at a time. If both (local and remote) are active the “drawer
ready switch” will be OFF and the motor cannot start.
NOTE: to make any changes on the configuration, “parameter allowed” must be enabled in WinESG
parameterization/function panel or Modbus function code 6 register 62.
Refer to section 2.2.1 for the motor control detailed configuration.
Star-delta open transition operation: when an ON1 command is received, contactor Y, controlled by EntelliPro ES
output relay 45, will close, connecting the motor in a Star configuration. When the Y contact feedback mapped to the
EntelliPro input is received, contactor K1, controlled by EntelliPro ES output relay 41, will close, connecting the motor to
the supply. The motor will start at 58% of the line voltage.
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 45 will de-energize; contactor Y opens, opening the Star 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.
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.
When an OFF command function is received the EntelliPro ES output relays 41, 43, or 45 open; contactor K1, Y, or K2
open and the motor stops.
