5.6.2. Signalling
The significance of signals (K51/1…K51/8) for the SACE PR113 protection unit is as follows:
Contact

Event which causes closing of relay
A
Alarm protection L (overload)
B
Pre-alarm function L (overload)
K51/1*

“*”The reason for the closing of these contacts (K51/1, K51/4 and K51/5) depends upon the configuration (event A or
event B) set via the dip-switch of the PR010/K unit, only if dip-sw N°5 is set to OFF (see par.5.6.1).
“§§” In the case of dip-sw N°5 set to ON all contacts (K51/1…K51/8) are exclusively associated with the function set
on the PR113 unit by the user, except contact K51/5 which shows ‘Internal Bus communication problem (bus KO)’.
5.6.3. Connection of 3 SACE PR010/K units with SACE PR113/P
It is possible to connect two or three SACE PR010/K units with a PR113/P unit (see par. 5.9.2).
The only condition being that one PR010/K unit must be configured as Master, with the other(s) configured as Slave.
In this way it is possible to activate up to (7 + 8 + 3 =) 18 contacts without potential (relay), plus 6 replicated (see
Emax manual).
