5.6.2.3.
User mode (see par. 4.5.3)
The dip-switches are to be set as follows: Dip-switch no. 5 = B, Dip-switch no. 11 = ignored.
All contacts (K51/1...K51/8) are associated exclusively with the function selected on the PR113 unit by the user, except
the K51/5 contact, which indicates the “Communication problems on the local bus (bus KO)” function.
5.6.3. Connection of 3 SACE PR021/K units with SACE PR113/P
Up to a maximum of three SACE PR021/K units can be connected to the PR113/P unit (see par. 5.14.4).
The only condition is that one PR021/K unit is to be configured as Master, while the other(s) is/are configured as
Slave(s).
This allows activating up to (7 + 8 + 3 =) 18 contacts without potential (K51/1, K51/2,...), plus 6 replicated contacts (see
Emax user manual).
5.6.2.2.
Latch mode (see par. 4.5.2)
The dip-switches are to be set as follows: Dip-switch no. 5 = A, Dip-switch no. 11 = ON.
