CHAPTER 2: INSTALL ATION/CONFIGURATION
EPOS MOTOR MANAGEMENT SYSTEM- INSTRUCTION MANUAL 2.75
When an OFF command is received, EntelliPro contact output relays 41 or 43 open, contactors K1 and K2 close, and the
motor stops. The starter logic is fully symmetrical between right and left.
Configuration 2 operation - limit switched activated and switch OFF at current threshold:
In order to start the motor on either direction, the limit switch 1 reached and limit switch 2 reached inputs (inputs 96 and
97on EntelliPro ES3 and inputs 18 and 19 on EntelliPro ES5) must NOT be active at the same time.
NOTE: If both limit switches inputs are active (input 96 and 97 on EntelliPro ES3 and 18 and 19 on EntelliPro ES5) a
“position switch” error will be generated, since this is an invalid condition.
When an ON1 right command is received, contactor K1, controlled by EntelliPro output relay 41, will close, provided the
motor is in the off state and the drawer ready switch is active, which will start the motor in a right direction. When the
limit switch 1 is reached (input 97 on EntelliPro ES3 and input 18 on EntelliPro ES5 active) and the current has exceeded
the typical specific threshold 4 set in WinESG parameterization/device settings panel or Modbus function code 6 register
21, the motor will stop and will not rotate in the same direction even when the current is below the threshold. The motor
can only re-start on the opposite direction by using command ON2, after the “motor ON direction switchover time” timer
set in WinESG parameterization/timer or Modbus function code 6 register 30 expires.
Similarly when an ON2 left command is received, contactor K2, controlled by EntelliPro output relay 43, will close,
provided the motor is in the off state and the drawer ready switch is active, which will start the motor in a left direction.
When the limit switch 1 is reached (input 96 on EntelliPro ES3 and input 19 on EntelliPro ES5 active) and the current has
exceeded the typical specific threshold 4 set in WinESG parameterization/device settings panel or Modbus function
code 6 register 21, the motor will stop and will not rotate in the same direction. The motor can only re-start on the
opposite direction by using command ON1, after the “motor ON direction switchover time” timer set in WinESG
parameterization/timer or Modbus function code 6 register 30 expires.
In case the motor is running in one direction and a command is received instructing the motor to rotate in opposite
direction, the decision of accepting the commands will be dependent on the configuration of the “allow direction
switchover” parameter set in WinESG parameterization/typical settings panel or the bit set on Modbus function code 6
register 111.
If this bit is set, the motor is allowed to accept the command, which will cause the motor to stop and wait for the
“motor ON direction switchover time” transfer timer to expire before starting the motor in the opposite direction.
When an OFF command is received, EntelliPro ES contact output relays 41 or 43 open, contactors K1 and K2 close, and
the motor stops. The starter logic is fully symmetrical between right and left.
