AUMA SQ 12.2 - Opening Terminal Compartment for Mains

8. Signals
8.1. Feedback signals (binary)
Information The switches can be provided as single switches (1NC and 1 NO), as tandem
switches (2 NC and 2 NO) or as triple switches (3 NC and 3 NO).The precise version
is indicated in the terminal plan or on the order-related technical data sheet.
Type and designation in wiring diagramFeedback signal
Signalling via limit switches (NO), non potential-free
Value of the output signal depends on control voltage (refer to wiring diagram)
End position OPEN/CLOSED
reached
Limit switch, closing, clockwise rotationLSC
Limit switch, opening, counterclockwise rotationLSO
Option: Tandem switch with additional potential-free contacts LSC1 and LSO1
Potential-free signal via switches (NC/NO)
Condition: DUO limit switching in the actuator
Intermediate position reached
(option)
DUO limit switch, clockwise rotationLSA
DUO limit switch, counterclockwise rotationLSB
Potential-free signal via contacts, terminals XK 15 and XK 16
Condition: Relay board A5 within the controls
Output contact XK 15 closed = no torque fault
Output contact XK 16 = torque fault, i.e. the set torque was exceeded before reaching an
end position.
