When using trip circuit supervision, address 182 74 Trip Ct Supv allows you to select whether this function
should work with two (2 Binary Inputs) or only one binary input (1 Binary Input) or if the function is
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. For
7SJ61 Port C (service port) is used for this purpose. 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 of the RTD-box (see Subsection 2.14.2, "RTD-box").
The flexible protection functions can be configured via parameter FLEXIBLE FUNC.. Up to 20 functions can
be created. This is done by setting checkmarks at the functions. If the checkmark of a function is removed, all
settings and configurations made previously will be lost. After re-selecting the function, all settings and config-
urations are in default setting. Setting of the flexible function is done in DIGSI under “Parameters“, “Additional
Functions“ and “Settings“. The configuration is done, as usual, under “Parameters“ and “Configuration“.
