• In addition to the status signals, the "QL..." lamp controls additionally
indicate the following:
– Unacknowledged fault (lamp output general fault QLS is flashing)
– Saving change-over command (QLE lamp outputs are flickering)
– Lamp test: All QL outputs are activated for approx. 2 s.
• Additional status information:
– Start active: If "Motor" is selected as the load type, this signal is present
during the start process of the motor for the duration of the specified
class time (e.g. 10 s for Class 10). Exceptions are the "Overload relay"
and "Solenoid valve" control functions.
– Interlocking time active: For control functions with a change in the
direction of rotation, the signal remains present until the specified
interlocking time has elapsed.
– Change-over pause active: For the "Dahlander", "Pole-changing starter"
and "Star-delta" control functions the signal is present until the specified
time has elapsed.
• Additional status information for the "Positioner" or "Solenoid valve" control
function:
– Feedback CLOSED (FC)
– Feedback OPEN (FO)
– Torque CLOSED (TC)
– Torque OPEN (TO).
These feedback signals specify the present status of the corresponding limit
switch and/or torque switch. The amount of usable status information is
directly dependent on the selected control function.
• Additional fault messages for the "Positioner" or "Solenoid valve" control
function:
– Stalled positioner: The torque switch has been activated before the
corresponding limit switch. The positioner may have stalled.
– Double 0: Both torque switches have been activated
– Double 1: Both limit switches have been activated
– End position: Positioner has left the end position without receiving a
control command
– Antivalence: The change-over contacts of the limit switch do not issue
an antivalent signal (only for the "Positioner 5" control function)
