Connect the terminals 10 and 11 when undervoltage release is used.
A - Alarm function
position 1: Alarm is OFF
position 0: Alarm is ON
B - Delay time multiplication constant
position 1: K = 10
position 0: K = 1
C/D - Sensitivity multiplication constant
c,d in position 0: K = 0,1
c in position 1, d in position 0: K = 1
c,d in position 1 K = 10
E - Fail Safe (Trip Contact)
position 1: the relay is normally energized (Fail Safe)
position 0: the relay is normally de-energized
F - Fail Safe (Alarm Contact)
position 1: the relay is normally energized (Fail Safe)
position 0: the relay is normally de-energized

Auxiliary Power Supply Vaux:
ELR72P
• Terminals 2 - 3 = 110 V ac (±20%)
• Terminals 1 - 2 = 230 V ac (±20%)
• Terminals 1 - 3 = 400 V ac (±20%)
ELR72V24P
• Terminals 2 - 3 = 24 V ac/dc (±20%)
• Terminals 1 - 3 = 48 V ac/dc (±20%)
Toroidal transformer connection:
- To link terminals 7 and 8 with toroidal
terminals S1 and S2 (measure)
- To link terminals 5 and 6 with toroidal
terminals T1 and T2 (test)
Remote reset / Autoreset:
- To link terminals 15 and 16 with NO pushbutton
in order to realize remote reset function.
- To link terminals 15 and 16 each other to
realize autoreset function.
