4.2 Functional specification for 33SR10 to 33SR14
The time delay relay has two separate starting circuits.
• The inputs are controlled via the internal 15 V voltage at S11 and 12 V voltage at S21.
• The start buttons must be connected between S11 and S12 (starting circuit 1)
and between S21 and S22 (starting circuit 2).
• Diagnostic contacts 14 and 24 close when the device is ready for operation
and open if there is a fault.
