Auxiliary Power Supply Vaux:
ELR48P
• Terminals 2 - 3 = 110 V ac/dc (±20%)
• Terminals 1 - 3 = 230 V ac (±20%)
ELR48V24P
• Terminals 2 - 3 = 24 V ac/dc (±20%)
• Terminals 1 - 3 = 48 V ac/dc (±20%)
Toroidal transformer connection:
To link the terminals 4 and 5 with toroidal terminals S1 and S2
A - Reset Mode
position 1: automatic reset
position 0: manual reset
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 - Output contacts Fail Safe
position 1: the relay is normally de-energized
position 0: the relay is normally energized (Fail Safe)
