CHAPTER 2: INSTALL ATION/CONFIGURATION
EPOS MOTOR MANAGEMENT SYSTEM- INSTRUCTION MANUAL 2.37
If Hardwire is selected as a controlling device, one input must be mapped to mode switch local and a different input to
mode switch remote. If input mode switch local is active, all mechanisms defined as locals can control the motor
(ON/OFF). If input mode switch remote is active, the mechanism defined as remote can control the motor (ON/OFF).
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 reverse open transition operation: When an ON1 command is received, contactor Y, controlled by
EntelliPro ES output relay 23, will close, connecting the motor in a Wye 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 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 41, 43 and 23 open, contactor K1, Y and K2 open
and the motor stops.
Similarly, when an ON2 command is received, contactor Y, controlled by EntelliPro ES output relay 23, will close,
connecting the motor in a Wye configuration. When the Y contact feedback mapped to the EntelliPro input is received,
contactor K3, controlled by EntelliPro ES output relay 45, will close, connecting the motor to the supply. The motor will
start at 58% of the line voltage.
