Function
A
Output
PE
Connection for cable screen
B
Input
Pulsen ein
Thermal pulse mode up to max. 50 Hz, fixed balance of
50%
C
Input
SYN_E
Synchronisation for master/slave operation
D
Output
IGRO Relais
Current flows signal
I > 0
Contact closed = welding current flowing
(forms contact with signal G)
E
Input
