Error Relay Output
A relay output on connector J14 is used to indicate ELISE2 module malfunction and can
also be used to indicate other errors. See application documentation for more information
about functionality.
Figure 12. Jumpering that decides when the error relay output is active, either
when the relay operates or is released.
The jumpering J15 decides if the output shall be active when the relay is operating or
released. 1-2 selects operating and 2-3 selects released. In
figure 12 , the relay is released
and as the jumpering is set to 1-2 the circuit is open and the error relay output is inactive.
At power-up or restart of the ELISE2, the relay is released until the applications are
working properly. If the relay is released longer, ELISE2 is malfunctioning.
RS232 Communication with External Unit
The ELISE2 has three identical RS232 connectors; J7, J8 and J11. Depending on software
application the RS232 ports can be used or not. How to connect external equipment to
the ELISE2 is described in the documentation of the software application.
In figure 13 , the RS232 connectors on the ELISE2 is described.
