5.5.2. Signalling
The significance of signals (K51/1…K51/8) for protection unit SACE PR112 is as follows:
Contact
N° Pin on unit
PR010/K
Event which causes closing of relay
K51/1
5
Alarm protection L (overload)
K51/2
6
Alarm protection S (selective short circuit)
K51/3
7
Alarm protection I (instantaneous short circuit)
A
Alarm protection G (ground fault)
K51/4 *

“*” The reason for the closing of these contacts (K51/4 e K51/5) depends upon the configuration, set via the dip-
switch (event A or event B), of the PR010/K unit (see par.5.3).
