P02.22 – This defines the control type for tie breakers (Cx). If the system layout includes tie breakers, this parameter must
be set to a value other than OFF.
P02.23-P02.24-P02.25-P02.26-P02.27 – Control parameters of breakers used as tie breakers. Similar to P02.17…P02.21
P02.28-P02.29 – Alphanumeric description (code) which will be displayed on the synoptic panels on the display to indi-
cate the two tie breakers (where used), respectively.
P02.30 – Tie breaker closing delay after closing the corresponding line breakers.
P02.31 – P02.33 – P02.35 – Advance time between energising of pre-transfer output and the actual de-energising of the
respective load. This controls the outputs programmed with the pre-transfer function.
P02.32-P02.34-P02.36 – Post-transfer output energising time after conclusion of the load transfer from one line to the other.
P02.37-P02.38 – When the breaker command mode is set to Continuous (P08.01 = Continuous control Q), this parameter
defines the ATL behaviour when moving to OFF mode. OFF = Command relays are de-energized. NOC = Com-
mand relays hold their previous status (NO Change).
P02.39, P02.40 – Conditional enable of C1 tie breaker. OFF = Tie breaker is enabled normally. (Any other setting) = C1
tie breaker is enabled only if the selected variable is active. When the variable is not active, if the tie breaker is
open, its closing will be avoided. If the tie breaker is closed, it will be opened.
P02.41, P02.42 – Like previous parameters, referred to C2.

P04.01 - Rated battery voltage. If set to OFF, disables the battery state alarms and messages on the display.
P04.02 - MAX battery voltage alarm tripping threshold.
P04.03 - MIN battery voltage alarm tripping threshold.
P04.04 - Tripping delay between MIN and MAX battery alarms.
P04.05-P04.06-P04.07-P04.08 - Serial communication enabling between 422684 and any BCG…RS series communica-
ting battery chargers. It allows to read the voltages, charging currents and alarms concerning the corresponding
battery charger and to view information on the dedicated video page. ‘Local’ means the battery charger con-
nected to the battery which powers the 422684 in DC.
