are displayed when you select the synchronizing function; function groups set to
Disabled are hidden.
When using the trip circuit monitoring, there is the possibility to select at address 182
74 Trip Ct Supv if the trip circuit monitoring should work with two (2 Binary
Inputs) or only with one binay input (1 Binary Input) or if the function will be con-
figured as Disabled.
If you want to detect an ambient temperature or a coolant temperature and e.g. send
the information to the overload protection, specify in address 190 RTD-BOX INPUT
the port to which the RTD-box is connected. In 7SJ62/63/64 port C (service port) is
used for this purpose, for 7SJ64 either port C (service port) or port D (additional port).
The number and transmission type of the temperature detectors (RTD = Resistance
Temperature Detector) can be specified in address191 RTD CONNECTION: 6 RTD
simplex or 6 RTD HDX (with one RTD-box) or 12 RTD HDX (with two RTD-boxes).
Implementation examples are given in the Appendix (under "Connection Examples").
The settings in address 191 have to comply with those at the RTD-box (see Subsec-
tion 2.20.2, under „RTD-box Settings").
Several options are available at address 172 52 B.WEAR MONIT for CB mainte-
nance. This does in no way affect the basic functionality of summation current forma-
tion (ΣI procedure), which does not require any additional settings and sums up the
tripping currents of the trips initiated by the protection function.
The ΣI
x
procedure creates the sum of all tripping current powers and displays them
as reference quantity. The 2P procedure continuously calculates the CB's remaining
lifetime.
2
The I t procedure is only implemented in the 7SJ64. It forms the squared tripping cur-
rrent integrals over the arcing time and displays them as reference quantity.
Section 2.23.3 provides more detailed information on CB maintenance procedures.
