Control Functions

Control functions (e.g. direct starters, reversing starters) are used for controlling load
feeders. They have the following important features:
● Monitoring the switch-on/switch-off sequence
● Monitoring the ON/OFF status
● Switching off in case of a fault.
For monitoring these statuses, SIMOCODE pro uses the auxiliary control input "Feedback
ON", which is usually derived directly from the current flow in the main circuit via the current
measurement modules.
All necessary interlocks and connections for the corresponding applications are already
implemented in the control functions.
Control functions contain:
● Plugs for control commands (ON <<, ON <, OFF, ON >, ON >>) that are usually
connected with the "Enabled Control Command" sockets.
● Auxiliary control inputs (plug ), e.g. Feedback ON
● Sockets for
– contactor controls QE1 to QE5
– displays (lamp controls) QL*, QLS
– statuses, e.g. "Status - ON <<, Status - ON >>"
– faults, e.g. "Trip - Feedback (FB) ON", "Trip - Antivalence"
● Settings, e.g. interlocking time
● A logic component with all necessary interlocking and connections for the control function
● Like control functions, the motor protection with its parameters and signals is active "at a
higher level in the background". Motor protection and thermistor protection are
independent functions that switch off the motor when activated via the control functions.
